Q48. Which of the following descriptions about the main implementation of single sign-on is wrong?

Accept PC message mode

Query the AD server security log mode

Query the syslog server mode

Firewall monitors AD authentication packets

Q49. USG firewall NAT configuration is as follows:

When FTP Server responds to Client A, it is converted to address 1.1.1.5 in address 1.

Source NAT configuration can only be converted for internal network users (10.1.1.0/24) to access the external network.

When changing the IP address of the FTP Server host to 1.11.3. Client A host can still access the FTP Server

Client A accesses FTP Server 1.1.1.1, the destination address is converted to 10.1.1.2, and the source address remains unchanged.

Q50. At this stage, we have mastered three source NAT technologies, namely NAT No-PAT, (), and Easy_IP

NAPT

Q51. Which of the following does not include the fragmented packets that a packet filtering firewall can filter?

Non-fragmented packets

First fragmented message

Forged ICMP error messages

Subsequent fragmented messages

Q52. There is no priority between custom signatures and predefined signatures. When traffic hits both custom signatures and predefined signatures, the final action will be based on the most stringent signature.

True

False

Q53. As shown in the figure is the process of AD single sign-on (accepting PC message mode). Please follow the process sequence and corresponding operations to match and associate.

Q54. The data format transmitted between data link layers in the OSI model is called a frame.

False

Q55. Which of the following options is the protocol number of GRE?

Q56. In an actual network environment, the session information of some special service data flows needs to not be aged for a long time. By configuring the long connection function, you can ensure the normal operation of this type of business. You can enable the long connection function by executing the command () enable.

Long-link

Q57. ____- The goal is to provide a rapid, composed and effective response in emergency situations, thereby enhancing the ability of the business to recover immediately from a disruptive event.[fill in the blank]*

business continuity plan

business continuity

Q58. Which of the following does not belong to Layer 2 VPN?

Different interfaces of the firewall can be in the same zone.

The zones that come with the firewall can be deleted.

The same interface on the firewall can belong to different zones.

Q60. Which of the following operations can be performed on data in a security posture? (Multiple Choice)

Q62. The IPS detects and analyzes all packets passing through a device and determines whether to permit or block the packets in real time based on the comprehensive detection mechanism. Sort the following steps into the correct order based on the basic implementation mechanism of the IPS.

Explanation:
* Protocol identification and analysis
* Application data reassembly
* Signature matching
* Attack response
The correct IPS processing order starts with protocol identification and analysis . Before an IPS can judge whether traffic is malicious, it must first determine what protocol is being used and analyze the packet structure according to the expected protocol behavior. This helps the device understand whether the traffic is HTTP, FTP, SMTP, DNS, or another protocol and prepares it for deeper inspection.
After that, the IPS performs application data reassembly . Many attacks are not visible in a single packet, so the IPS must reconstruct fragmented or segmented traffic into complete application data. This allows the device to inspect the real payload content rather than isolated packet pieces.
Once the data is reassembled, the IPS performs signature matching . At this stage, the traffic content and behavior are compared with known attack signatures, protocol anomalies, and detection rules to determine whether the traffic matches a malicious pattern such as injection, buffer overflow, or directory traversal.
Finally, the IPS performs the attack response . Based on the detection result, it may permit, block, reset, alarm, or log the traffic. Therefore, the correct order is D # A # B # C .
