QUESTION 75
A company has HPE Aruba Networking Mobility Controllers (MCs), campus APs, and AOS-CX switches. The company plans to use HPE Aruba Networking ClearPass Policy Manager (CPPM) to classify endpoints by type. This company is using only CPPM and no other HPE Aruba Networking ClearPass solutions.
The HPE Aruba Networking ClearPass admins tell you that they want to use HTTP User-Agent strings to help profile the endpoints.
What should you do as a part of setting up Mobility Controllers (MCs) to support this requirement?

Create datapath mirrors that use the CPPM’s IP address as the destination.

Create an IF-MAP profile, which specifies credentials for an API admin account on CPPM.

Create control path mirrors to mirror HTTP traffic from clients to CPPM.

Create a firewall whitelist rule that permits HTTP and CPPM’s IP address.

HPE Aruba Networking ClearPass Policy Manager (CPPM) uses device profiling to classify endpoints, and one of its profiling methods involves analyzing HTTP User-Agent strings to identify device types (e.g., iPhone, Windows laptop). HTTP User-Agent strings are sent in HTTP headers when a client accesses a website. For CPPM to profile devices using HTTP User-Agent strings, it must receive the HTTP traffic from the clients. In this scenario, the company is using Mobility Controllers (MCs), campus APs, and AOS-CX switches, and CPPM is the only ClearPass solution in use.
HTTP User-Agent Profiling: CPPM can passively profile devices by analyzing HTTP traffic, but it needs to receive this traffic. In an AOS-8 architecture, the MC can mirror client traffic to CPPM for profiling. Since HTTP traffic is part of the data plane (user traffic), the MC must mirror the data plane traffic (not control plane traffic) to CPPM.
Option A, “Create datapath mirrors that use the CPPM’s IP address as the destination,” is correct. The MC can be configured to mirror client HTTP traffic to CPPM using a datapath mirror (also known as a GRE mirror). This involves setting up a mirror session on the MC that sends a copy of the client’s HTTP traffic to CPPM’s IP address. CPPM then analyzes the HTTP User-Agent strings in this traffic to profile the endpoints. For example, the command mirror session 1 destination ip <CPPM-IP> source ip any protocol http can be used to mirror HTTP traffic to CPPM.
Option B, “Create an IF-MAP profile, which specifies credentials for an API admin account on CPPM,” is incorrect. IF-MAP (Interface for Metadata Access Points) is a protocol used for sharing profiling data between ClearPass and other systems (e.g., Aruba Introspect), but it is not used for sending HTTP traffic to CPPM for profiling. Additionally, IF-MAP is not relevant when only CPPM is in use.
Option C, “Create control path mirrors to mirror HTTP traffic from clients to CPPM,” is incorrect. Control path (control plane) traffic includes management traffic between the MC and APs (e.g., AP registration, heartbeats), not client HTTP traffic. HTTP traffic is part of the data plane, so a datapath mirror is required, not a control path mirror.
Option D, “Create a firewall whitelist rule that permits HTTP and CPPM’s IP address,” is incorrect. A firewall whitelist rule on the MC might be needed to allow traffic to CPPM, but this is not the primary step for enabling HTTP User-Agent profiling. The key requirement is to mirror the HTTP traffic to CPPM, which is done via a datapath mirror, not a firewall rule.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
“To enable ClearPass Policy Manager (CPPM) to profile devices using HTTP User-Agent strings, the Mobility Controller (MC) must mirror client HTTP traffic to CPPM. This is done by creating a datapath mirror session that sends a copy of the client’s HTTP traffic to CPPM’s IP address. For example, use the command mirror session 1 destination ip <CPPM-IP> source ip any protocol http to mirror HTTP traffic to CPPM. CPPM then analyzes the HTTP User-Agent strings to classify endpoints by type (e.g., iPhone, Windows laptop).” (Page 350, Device Profiling with CPPM Section) Additionally, the HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide notes:
“HTTP User-Agent profiling requires ClearPass to receive HTTP traffic from clients. In an Aruba Mobility Controller environment, configure a datapath mirror to send HTTP traffic to ClearPass’s IP address. ClearPass will parse the HTTP User-Agent strings to identify device types and operating systems, enabling accurate profiling.” (Page 249, HTTP User-Agent Profiling Section)

QUESTION 76
A company has Aruba Mobility Controllers (MCs), Aruba campus APs, and ArubaOS-CX switches. The company plans to use ClearPass Policy Manager (CPPM) to classify endpoints by type. The company is contemplating the use of ClearPass’s TCP fingerprinting capabilities.
What is a consideration for using those capabilities?

ClearPass admins will need to provide the credentials of an API admin account to configure on Aruba devices.

You will need to mirror traffic to one of CPPM’s span ports from a device such as a core routing switch.

ArubaOS-CX switches do not offer the support necessary for CPPM to use TCP fingerprinting on wired endpoints.

TCP fingerprinting of wireless endpoints requires a third-party Mobility Device Management (MDM) solution.

QUESTION 77
How should admins deal with vulnerabilities that they find in their systems?

They should apply fixes, such as patches, to close the vulnerability before a hacker exploits it.

They should add the vulnerability to their Common Vulnerabilities and Exposures (CVE).

They should classify the vulnerability as malware. a DoS attack or a phishing attack.

They should notify the security team as soon as possible that the network has already been breached.

QUESTION 78
What is one way that WPA3-Enterprise enhances security when compared to WPA2-Enterprise?

WPA3-Enterprise implements the more secure simultaneous authentication of equals (SAE), while WPA2-Enterprise uses 802.1X.

WPA3-Enterprise provides built-in mechanisms that can deploy user certificates to authorized end-user devices.

WPA3-Enterprise uses Diffie-Hellman in order to authenticate clients, while WPA2-Enterprise uses 802.1X authentication.

WPA3-Enterprise can operate in CNSA mode, which mandates that the 802.11 association uses secure algorithms.

QUESTION 79
Which attack is an example or social engineering?

An email Is used to impersonate a Dank and trick users into entering their bank login information on a fake website page.

A hacker eavesdrops on insecure communications, such as Remote Desktop Program (RDP). and discovers login credentials.

A user visits a website and downloads a file that contains a worm, which sell-replicates throughout the network.

An attack exploits an operating system vulnerability and locks out users until they pay the ransom.

QUESTION 80
Your HPE Aruba Networking Mobility Master-based solution has detected a rogue AP. Among other information, the AOS Detected Radios page lists this information for the AP:
SSID = PublicWiFi
BSSID = a8:bd:27:12:34:56
Match method = Plus one
Match method = Eth-Wired-Mac-Table
The security team asks you to explain why this AP is classified as a rogue. What should you explain?

The AP has been detected using multiple MAC addresses. This indicates that the AP is spoofing its MAC address, which qualifies it as a suspected rogue.

The AP is probably connected to your LAN because it has a BSSID that is close to a MAC address that has been detected in your LAN. Because it does not belong to the company, it is a suspected rogue.

The AP is an AP that belongs to your solution. However, the AOS has detected that it is behaving suspiciously. It might have been compromised, so it is classified as a suspected rogue.

The AP has a BSSID that is close to your authorized APs’ BSSIDs. This indicates that the AP might be spoofing the corporate SSID and attempting to lure clients to it, making the AP a suspected rogue.

HPE Aruba Networking’s Wireless Intrusion Prevention (WIP) system, part of the AOS-8 architecture (Mobility Master and Mobility Controllers), is designed to detect and classify rogue APs. The “AOS Detected Radios” page provides details about detected APs, including their SSID, BSSID, and match methods used to classify them.
In this case, the AP is classified as a rogue with the following match methods:
Plus one: This indicates that the BSSID of the detected AP is numerically close (e.g., differs by one in the last octet) to the MAC address of a known device in the network.
Eth-Wired-Mac-Table: This indicates that the AP’s MAC address (or a closely related MAC address) was found in the wired network’s MAC address table, suggesting that the AP is connected to the LAN.
These match methods suggest that the AP is likely connected to the company’s wired LAN (via the Eth-Wired-Mac-Table match) and has a BSSID that is close to a known device’s MAC address (Plus one match). Since this AP is not part of the company’s authorized AP list (it’s broadcasting “PublicWiFi,” which may not be a corporate SSID), it is classified as a suspected rogue. This scenario is common when an unauthorized AP is plugged into the corporate LAN, posing a security risk.
Option A, “The AP has been detected using multiple MAC addresses,” is incorrect because the match methods do not indicate multiple MAC addresses; they indicate a close match to a known MAC and a presence in the wired MAC table.
Option C, “The AP is an AP that belongs to your solution,” is incorrect because the AP is classified as a rogue, meaning it is not part of the authorized APs in the solution.
Option D, “The AP has a BSSID that is close to your authorized APs’ BSSIDs,” is partially correct in that the “Plus one” match indicates a close BSSID, but the key reason for the rogue classification is its connection to the LAN (Eth-Wired-Mac-Table), not just the BSSID similarity.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
“The Wireless Intrusion Prevention (WIP) system detects rogue APs by analyzing their BSSIDs, SSIDs, and connectivity to the wired network. The ‘Eth-Wired-Mac-Table’ match method indicates that the AP’s MAC address (or a closely related address) was found in the wired network’s MAC address table, suggesting that the AP is connected to the LAN. The ‘Plus one’ match method indicates that the AP’s BSSID is numerically close to a known MAC address in the network, which can indicate a potential rogue device attempting to mimic a legitimate device.” (Page 412, Rogue AP Detection Section) Additionally, the guide notes:
“A rogue AP is classified as ‘suspected rogue’ if it is detected on the wired network (e.g., via Eth-Wired-Mac-Table) and is not part of the authorized AP list. This often occurs when an unauthorized AP is connected to the corporate LAN.” (Page 413, Rogue AP Classification Section)

QUESTION 83
You have been instructed to look in an AOS Security Dashboard’s client list. Your goal is to find clients that belong to the company and have connected to devices that might belong to hackers.
Which client fits this description?

MAC address: d8:50:e6:f3:6d:a4; Client Classification: Authorized; AP Classification: Suspected Rogue

MAC address: d8:50:e6:f3:6e:c5; Client Classification: Interfering; AP Classification: Neighbor

MAC address: d8:50:e6:f3:6e:60; Client Classification: Interfering; AP Classification: Interfering

MAC address: d8:50:e6:f3:70:ab; Client Classification: Interfering; AP Classification: Suspected Rogue

The AOS Security Dashboard in an AOS-8 solution (Mobility Controllers or Mobility Master) provides a client list through its Wireless Intrusion Prevention (WIP) system, showing the classification of clients and the APs they are connected to. The goal is to identify clients that belong to the company (Authorized clients) and have connected to devices that might belong to hackers (rogue or suspected rogue APs).
Client Classification:
Authorized: A client that has successfully authenticated to an authorized AP and is part of the company’s network (e.g., an employee device).
Interfering: A client that is not authenticated to the company’s network and is considered external or potentially malicious.
AP Classification:
Authorized: An AP that is part of the company’s network and managed by the MC.
Suspected Rogue: An AP that is not authorized and is suspected of being malicious, often because it exhibits suspicious behavior (e.g., a BSSID close to an authorized AP, indicating potential spoofing).
Neighbor: An AP that is not part of the company’s network but is not connected to the wired network (e.g., a nearby AP from another organization).
Interfering: An AP that is not part of the company’s network and may be causing interference, but is not necessarily malicious.
The requirement is to find a client that is Authorized (belongs to the company) and connected to a Suspected Rogue AP (might belong to hackers).
Option A: MAC address: d8:50:e6:f3:6d:a4; Client Classification: Authorized; AP Classification: Suspected Rogue This client is classified as “Authorized,” meaning it belongs to the company, and it is connected to a “Suspected Rogue” AP, which might belong to hackers. This matches the requirement perfectly.
Option B: MAC address: d8:50:e6:f3:6e:c5; Client Classification: Interfering; AP Classification: Neighbor This client is “Interfering” (not a company client) and connected to a “Neighbor” AP, which is not considered a hacker’s device (it’s just a nearby AP).
Option C: MAC address: d8:50:e6:f3:6e:60; Client Classification: Interfering; AP Classification: Interfering This client is “Interfering” (not a company client) and connected to an “Interfering” AP, which is not necessarily a hacker’s device (it may just be causing interference).
Option D: MAC address: d8:50:e6:f3:70:ab; Client Classification: Interfering; AP Classification: Suspected Rogue This client is “Interfering” (not a company client), although it is connected to a “Suspected Rogue” AP. It does not meet the requirement of being a company client.
The HPE Aruba Networking AOS-8 8.11 User Guide states:
“The Security Dashboard’s client list in ArubaOS shows the classification of each client and the AP it is connected to. An ‘Authorized’ client is one that has successfully authenticated to an authorized AP and is part of the company’s network. A ‘Suspected Rogue’ AP is an unauthorized AP that exhibits suspicious behavior, such as a BSSID close to an authorized AP, indicating potential spoofing by a hacker. To identify security risks, look for authorized clients connected to suspected rogue APs, as this may indicate a company device has connected to a malicious AP.” (Page 415, Security Dashboard Section) Additionally, the HPE Aruba Networking Security Guide notes:
“WIP classifies clients as ‘Authorized’ if they have authenticated to an authorized AP managed by the controller. A ‘Suspected Rogue’ AP is a potential threat, as it may be attempting to mimic a legitimate AP to lure clients. Identifying authorized clients connected to suspected rogue APs is critical for detecting potential attacks, such as man-in-the-middle attempts by hackers.” (Page 78, WIP Classifications Section)

QUESTION 85
What is a Key feature of me ArubaOS firewall?

The firewall is stateful which means that n can track client sessions and automatically allow return traffic for permitted sessions

The firewall Includes application layer gateways (ALGs). which it uses to filter Web traffic based on the reputation of the destination web site.

The firewall examines all traffic at Layer 2 through Layer 4 and uses source IP addresses as the primary way to determine how to control traffic.

The firewall is designed to fitter traffic primarily based on wireless 802.11 headers, making it ideal for mobility environments

QUESTION 86
You are deploying an Aruba Mobility Controller (MC). What is a best practice for setting up secure management access to the ArubaOS Web UP

Avoid using external manager authentication tor the Web UI.

Change the default 4343 port tor the web UI to TCP 443.

Install a CA-signed certificate to use for the Web UI server certificate.

Make sure to enable HTTPS for the Web UI and select the self-signed certificate Installed in the factory.

QUESTION 87
What is one difference between EAP-Tunneled Layer security (EAP-TLS) and Protected EAP (PEAP)?

EAP-TLS creates a TLS tunnel for transmitting user credentials, while PEAP authenticates the server and supplicant during a TLS handshake.

EAP-TLS requires the supplicant to authenticate with a certificate, hut PEAP allows the supplicant to use a username and password.

EAP-TLS begins with the establishment of a TLS tunnel, but PEAP does not use a TLS tunnel as part of Its process

EAP-TLS creates a TLS tunnel for transmitting user credentials securely while PEAP protects user credentials with TKIP encryption.

QUESTION 92
Refer to the exhibit.
A company has an HPE Aruba Networking Instant AP cluster. A Windows 10 client is attempting to connect to a WLAN that enforces WPA3-Enterprise with authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM). CPPM is configured to require EAP-TLS. The client authentication fails. In the record for this client’s authentication attempt on CPPM, you see this alert.
What is one thing that you check to resolve this issue?

Whether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster

Whether the client has a valid certificate installed on it to let it support EAP-TLS

Whether EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster

Whether the client has a third-party 802.1X supplicant, as Windows 10 does not support EAP-TLS

The scenario involves an HPE Aruba Networking Instant AP (IAP) cluster with a WLAN configured for WPA3-Enterprise security, using HPE Aruba Networking ClearPass Policy Manager (CPPM) as the authentication server. CPPM is set to require EAP-TLS for authentication. A Windows 10 client attempts to connect but fails, and the CPPM Access Tracker shows an error: “Client does not support configured EAP methods,” with the error code 9015 under the RADIUS protocol category.
EAP-TLS (Extensible Authentication Protocol – Transport Layer Security) is a certificate-based authentication method that requires both the client (supplicant) and the server (CPPM) to present valid certificates during the authentication process. The error message indicates that the client does not support the EAP method configured on CPPM (EAP-TLS), meaning the client is either not configured to use EAP-TLS or lacks the necessary components to perform EAP-TLS authentication.
Option B, “Whether the client has a valid certificate installed on it to let it support EAP-TLS,” is correct. EAP-TLS requires the client to have a valid client certificate issued by a trusted Certificate Authority (CA) that CPPM trusts. If the Windows 10 client does not have a client certificate installed, or if the certificate is invalid (e.g., expired, not trusted by CPPM, or missing), the client cannot negotiate EAP-TLS, resulting in the error seen in CPPM. This is a common issue in EAP-TLS deployments, and checking the client’s certificate is a critical troubleshooting step.
Option A, “Whether EAP-TLS is enabled in the AAA Profile settings for the WLAN on the IAP cluster,” is incorrect because the error indicates that CPPM received the authentication request and rejected it due to the client’s inability to support EAP-TLS. This suggests that the IAP cluster is correctly configured to use EAP-TLS (as the request reached CPPM with EAP-TLS as the method). The AAA profile on the IAP cluster is likely already set to use EAP-TLS, or the error would be different (e.g., a connectivity or configuration mismatch issue).
Option C, “Whether EAP-TLS is enabled in the SSID Profile settings for the WLAN on the IAP cluster,” is incorrect for a similar reason. The SSID profile on the IAP cluster defines the security settings (e.g., WPA3-Enterprise), and the AAA profile specifies the EAP method. Since the authentication request reached CPPM with EAP-TLS, the IAP cluster is correctly configured to use EAP-TLS.
Option D, “Whether the client has a third-party 802.1X supplicant, as Windows 10 does not support EAP-TLS,” is incorrect because Windows 10 natively supports EAP-TLS. The built-in Windows 10 802.1X supplicant (Windows WLAN AutoConfig service) supports EAP-TLS, provided a valid client certificate is installed. A third-party supplicant is not required.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
“EAP-TLS requires both the client and the server to present a valid certificate during the authentication process. If the client does not have a valid certificate installed, or if the certificate is not trusted by ClearPass (e.g., the issuing CA is not in the ClearPass trust list), the authentication will fail with an error such as ‘Client does not support configured EAP methods’ (Error Code 9015). To resolve this, ensure that the client has a valid certificate installed and that the certificate’s issuing CA is trusted by ClearPass.” (Page 295, EAP-TLS Troubleshooting Section) Additionally, the HPE Aruba Networking Instant 8.11 User Guide notes:
“For WPA3-Enterprise with EAP-TLS, the client must have a valid client certificate installed to authenticate successfully. If the client lacks a certificate or the certificate is invalid, the authentication will fail, and ClearPass will log an error indicating that the client does not support the configured EAP method.” (Page 189, WPA3-Enterprise Configuration Section)

QUESTION 93
You have deployed a new HPE Aruba Networking Mobility Controller (MC) and campus APs (CAPs). One of the WLANs enforces 802.1X authentication to HPE Aruba Networking ClearPass Policy Manager (CPPM). When you test connecting the client to the WLAN, the test fails. You check ClearPass Access Tracker and cannot find a record of the authentication attempt. You ping from the MC to CPPM, and the ping is successful.
What is a good next step for troubleshooting?

Renew CPPM’s RADIUS/EAP certificate.

Check connectivity between CPPM and a backend directory server.

Check CPPM Event Viewer.

Reset the user credentials.

In this scenario, a new HPE Aruba Networking Mobility Controller (MC) and campus APs (CAPs) are deployed, with a WLAN configured for 802.1X authentication using HPE Aruba Networking ClearPass Policy Manager (CPPM) as the RADIUS server. A client test fails, and no record of the authentication attempt appears in ClearPass Access Tracker. However, a ping from the MC to CPPM is successful, confirming basic network connectivity between the MC and CPPM.
The absence of a record in Access Tracker indicates that CPPM did not receive the RADIUS authentication request from the MC, or the request was rejected at a low level before being logged in Access Tracker. Access Tracker typically logs all RADIUS authentication attempts (successful or failed), so the lack of a record suggests a configuration or connectivity issue at the RADIUS level.
Option C, “Check CPPM Event Viewer,” is correct. The CPPM Event Viewer logs system-level events, including RADIUS-related errors that might not appear in Access Tracker. For example, if the MC’s IP address is not configured as a Network Access Device (NAD) in CPPM, or if the shared secret between the MC and CPPM does not match, CPPM may reject the RADIUS request before it reaches Access Tracker. The Event Viewer will log such errors (e.g., “RADIUS authentication attempt from unknown NAD”), providing insight into why the request was not processed.
Option A, “Renew CPPM’s RADIUS/EAP certificate,” is incorrect because the issue is that CPPM did not receive or process the authentication request (no record in Access Tracker). If there were a certificate issue (e.g., an expired or untrusted certificate), the request would still reach CPPM, and Access Tracker would log a failure with a certificate-related error.
Option B, “Check connectivity between CPPM and a backend directory server,” is incorrect because the issue occurs before CPPM processes the authentication request. If CPPM cannot contact a backend directory server (e.g., Active Directory), the authentication attempt would still be logged in Access Tracker with a failure reason related to the directory server.
Option D, “Reset the user credentials,” is incorrect because the issue is not related to the user’s credentials. The authentication request never reached CPPM, so the credentials were not evaluated.
The HPE Aruba Networking ClearPass Policy Manager 6.11 User Guide states:
“If an authentication attempt does not appear in Access Tracker, it indicates that the RADIUS request was not received by ClearPass or was rejected at a low level before being logged. The Event Viewer (Monitoring > Event Viewer) should be checked for system-level errors, such as ‘RADIUS authentication attempt from unknown NAD’ or shared secret mismatches. For example, if the Network Access Device (NAD) IP address of the Mobility Controller is not configured in ClearPass, or if the shared secret does not match, the request will be dropped, and an error will be logged in the Event Viewer.” (Page 301, Troubleshooting RADIUS Issues Section) Additionally, the HPE Aruba Networking AOS-8 8.11 User Guide notes:
“When troubleshooting 802.1X authentication issues, verify that the Mobility Controller can communicate with the RADIUS server. If a ping is successful but no authentication records appear in the RADIUS server’s logs (e.g., ClearPass Access Tracker), check the RADIUS server’s system logs (e.g., ClearPass Event Viewer) for errors related to NAD configuration or shared secret mismatches.” (Page 498, Troubleshooting 802.1X Authentication Section)

QUESTION 94
What are the roles of 802.1X authenticators and authentication servers?

The authenticator stores the user account database, while the server stores access policies.

The authenticator supports only EAP, while the authentication server supports only RADIUS.

The authenticator is a RADIUS client and the authentication server is a RADIUS server.

The authenticator makes access decisions and the server communicates them to the supplicant.

QUESTION 95
What is one way that WPA3-PerSonal enhances security when compared to WPA2-Personal?

WPA3-Perscn3i is more secure against password leaking Because all users nave their own username and password

WPA3-Personai prevents eavesdropping on other users’ wireless traffic by a user who knows the passphrase for the WLAN.

WPA3-Personai is more resistant to passphrase cracking Because it requires passphrases to be at least 12 characters

WPA3-Personal is more complicated to deploy because it requires a backend authentication server
