Termination

NO.91 Huawei Agile Cloud Authentication (HACA) supports only IMaster NCE-Campus as the HACA server.

True

False

According to the Huawei documents and resources, Huawei Agile Cloud Authentication (HACA) supports iMaster NCE-Campus as well as Agile Controller-Campus as the HACA server. HACA is an authentication method that allows users to access a network without entering user names or passwords 3 . Therefore, B is the correct answer.

NO.92 Arrange the following steps in the correct order for upgrading the leader AP and Fit AP.

NO.93 Which of the following statements are true about the WLAN site survey In different typical scenarios? (Select All that Apply)

In a classroom scenario. If the walls are made of reinforced concrete, the signal attenuation Is high. In this case, you are advised to test the attenuation during the site survey. Additionally, pay attention to the locations of ELV rooms in the teaching building.

In an office scenario, the load-bearing columns and partitions affect the signal coverage. If an integrated ceiling is used, deploy APs near maintenance entrances. If a metal ceiling is used, mount APs on the ceiling or wall.

In a ward-round scenario, high requirements are posed on the coverage field strength, roaming effect, and bandwidth. Determine the interference of medical equipment and the areas where Wi-Fi signals are not allowed.

In a stadium scenario, the onsite environment is complex and cabling is difficult. Therefore, confirm with the property management company about ELV rooms and cabling. If the transmission distance is too long, consider deploying more switches. During the survey, focus on the interference between APs and AP mounting modes.

Explanation
Only: All statements are true about the WLAN site survey in different typical scenarios.

NO.94 On a campus network, which of the following problems may occur when you manually create a static VXLAN tunnel? (Select All that Apply)

Although the static VXLAN tunnel mode supports the distributed gateway scenario, the configuration involves a heavy workload and is complex to adjust.

A static VXLAN tunnel uses related protocols on the control plane, consuming device resources.

If N devices need to establish VXLAN tunnels, you need to manually configure the ingress replication list up to N x (N-l)/2 times.

Remote MAC addresses can be learned only through data flooding.

Explanation
B is false because a static VXLAN tunnel does not use any protocols on the control plane, saving device resources.

NO.95 In centralized gateway deployments, border nodes are used as gateways, facilitating centralized management and simplifying O & M. In distributed gateway deployments, edge nodes are used as gateways, facilitating network expansion.

TRUE

FALSE

NO.96 In the early phase of a project, after the project requirements are clarified, the project owner should Checklist to describe the customer ‘ s requirements. (Capitalize the first letter of each word.)

Customer Requirement Specification
Explanation:
Customer Requirement Specification (CRS) is a document that needs to be output after the project requirements are clarified. The CRS describes the customer’s requirements in detail and serves as the basis for subsequent project design and delivery.
References: https://support.huawei.com/enterprise/en/doc/EDOC1100058940/8a8f1c9b/crs

NO.97 In 802. IX authentication using port-based access control, once a user is authenticated successfully on a port, subsequent users on this port can access the network without authentication. When the authenticated user goes offline, all other users are denied access to the network.

True

False

According to the Huawei documents and resources, 802.1X authentication using port-based access control is a method that allows only one user to access the network through a po rt at a time. If a user is authenticated successfully on a port, subsequent users on this port can access the network without authentication. When the authenticated user goes offline, all other users are denied access to the network 1 . Therefore, A is the correct answer.

NO.98 A Wi-Fi RFID tag is a signal generator manufactured by tag vendors to help locate the objects. Which of the following types of tags can be located by Huawei devices?

Hotspot tag

AeroScout tag

Location tag

Ekahau tag

NO.99 According to the configurations displayed on a customer ‘ s WAC, which of the following statements are true?

On the WLAN, a single AP supports a maximum of 30 access STAs or 32 roaming STAs.

When 30 STAs are connected to an AP, the AP ‘ s SSID is hidden. However, new STAs that know the SSID can still connect to the AP.

If 30 STAs are connected to the AP, the AP allows a maximum of 32 roaming STAs.

If 28 STAs are connected to the AP, the AP allows a maximum of four roaming STAs.

NO.100 The display sync-configuration compare command is executed on the backup WAC in HSB to check wireless configuration synchronization. Based on the command output, which of the following statements are true?
(Select All that apply)

This command is used to check whether the public configurations on two WACs are consistent after wireless configuration synchronization.

The configuration of ssid-profile 2 exists on both the master and backup WACs.

The configuration of vap-profile name 3 exists on the master WAC but not on the backup WAC.

The configuration of vap-profile name 2 exists on the backup WAC but not on the master WAC.

The display sync-configuration compare command is used to check whether the public configurations on two WACs are consistent after wireless configuration synchronization. The command output shows the differences between the configurations on the master and backup WACs. In this case, the configuration of vap- profile name 3 exists on the master WAC but not on the backup WAC.

NO.101 Which of the fallowings is not an IPv6 address type?

Multicast address

Unicast address

Broadcast address

Anycast address

Broadcast address is not an IPv6 address type. IPv6 does not support broadcast addressing, but uses multicast addressing instead. The other options are valid IPv6 address types. Unicast address identifies a single interface, multicast address identifies a group of interfaces, and anycast address identifies multiple interfaces but delivers packets to only one of them.

NO.102 Which of the following parameters can be allocated to clients In DHCPv6 stateful autoconflguratlon? (Select All that Apply)

IPv6 address

PD prefix

SNTP server address

DNS server address

Explanation
In DHCPv6 stateful autoconfiguration, a client obtains an IPv6 address, a PD prefix (if required), and other configuration parameters (such as DNS server address) from a DHCPv6 server.

NO.103 In Huawei ‘ s QoudCampus Solution, deployment through the registration center is as follows: A network device connects to the Internet and then automatically sends a request to the registration center to obtain the IP address/URL and port number of iMaster NCE-Campus. Once the device obtains this information, it automatically registers with (Master NCE-Campus and goes online.

TRUE

FALSE

NO.104 In Huawei’s smart roaming solution, which of the following methods can be used by a WAC to discover and maintain neighboring AP entries of STAs? (Select All that Apply)

The WAC obtains such entries using 802. 11v.

The AP listens to the Probe frames sent by STAs.

The AP periodically and proactively scans neighboring APs of STAs.

STAs proactively report neighboring AP information.

Explanation
In Huawei’s smart roaming solution, the WAC can discover and maintain neighboring AP entries of STAs by using two methods: passive listening and active scanning. Passive listening means that the AP listens to the Probe frames sent by STAs and reports them to the WAC. Active scanning means that the AP periodically and proactively scans neighboring APs of STAs and reports them to the WAC.
