NEW QUESTION # 24
In the figure, FW_A connects to FW_B through two links working in active/standby mode. When the active link of FW_A is faulty, the old IPsec tunnel 1 needs to be torn down, and IPsec tunnel 2 needs to be established with FW_B through the standby link to route traffic. In this case, configuring the IKE _____ detection mechanism on FW_A helps detect link faults and tear down the IPsec tunnel.(Enter lowercase letters.)

Answer:

Explanation:
dpd
Explanation:
* What is IKE DPD (Dead Peer Detection)?
* IKE DPD (Dead Peer Detection)is a mechanism used inIPsec VPNsto check if a remote VPN peer is still reachable.
* It allows the firewall to detectlink failuresandautomatically tear down and re-establish IPsec tunnelswhen necessary.
* Why is DPD required in this scenario?
* The network uses an active/standby link setup:
* IPsec Tunnel 1 (Active) # Uses Link 1 (GE0/0/1).
* IPsec Tunnel 2 (Standby) # Uses Link 2 (GE0/0/2).
* IfLink 1 fails, the firewall must detect the failure andtear down IPsec Tunnel 1before establishingIPsec Tunnel 2 over Link 2.
* DPD detects unreachable peersand triggers a failover.
* How does IKE DPD work?
* DPD periodically sends probes (HELLO messages) to the remote VPN peer.
* If no response is received within a timeout period, the firewall assumes the peer is down.
* Thefirewall deletes the IPsec tunnel and switches to the backup link.
* Why is the answer "dpd" (lowercase)?
* The questionexplicitly asks for lowercase letters.
* "dpd" (Dead Peer Detection) is the correct technical term in Huawei firewalls and networking standards.

NEW QUESTION # 25
Which of the following operations can be performed to harden the Windows operating system?(Select All that Apply)

A. Periodically check account permissions.
B. Cancel default sharing.
C. Change the default TTL value.
D. Restrict the number of users.

Answer: A,B,D

Explanation:
Comprehensive and Detailed Explanation:
* Windows system hardening improves security by reducing attack surfaces.
* Recommended security measures include:
* A. Periodically checking account permissions# Prevents unauthorized access.
* B. Canceling default sharing# Reduces exposure to remote attacks.
* C. Restricting the number of users# Limits access to essential personnel.
* Why is D incorrect?
* Changing the default TTL value does not directly enhance system security.

NEW QUESTION # 26
Sort the intrusion prevention steps in sequence based on the working mechanism of the firewall device.

Answer:

Explanation:

Explanation:
Intrusion Prevention Systems (IPS) in firewalls follow amulti-step processto detect and mitigate threats. The steps occur in a logical sequence:
1##Step 1: Identifies and Parses Application-Layer Protocols
* The firewall firstidentifies the protocol being used(e.g., HTTP, FTP, DNS, SMTP).
* Parsing the protocol helps the IPS engineunderstand how the data is structuredand what types of attacks might be embedded.
* This step is crucial for detectingprotocol-based attackslike SQL injection or cross-site scripting (XSS).
2##Step 2: Reassembles IP Fragments and TCP Flows
* Attackers oftensplit malicious payloads across multiple packetsto evade detection.
* The firewallreassembles fragmented packets and TCP flowsto reconstruct the full data stream.
* This step is critical for detectingevasion techniques such as fragmented attacks or out-of-order packet attacks.
3##Step 3: Performs Signature Matching
* Once the full data stream is reassembled, the IPScompares it against known attack signatures.
* Signature matching helps detect:
* Malware patterns(e.g., botnets, Trojans).
* Exploits targeting vulnerabilitiesin software and operating systems.
* Firewalls usepredefined signature databasesthat are regularly updated.
4##Step 4: Performs the Response Action Based on the IPS Profile
* If an attack is detected, the firewall takes anaction based on the IPS policy:
* Block the traffic(drop malicious packets).
* Alert the administrator(generate logs and alerts).
* Rate-limit traffic(slow down potential attack sources).
* Theresponse mechanism is customizablebased on security requirements.
