NEW QUESTION # 16
When an IPsec VPN is established in aggressive mode, AH+ESP can be used to encapsulate packets in NAT traversal scenarios.
- A. TRUE
- B. FALSE
Answer: B
Explanation:
Comprehensive and Detailed Explanation:
* Aggressive modeis a faster IKE Phase 1 negotiation method butdoes not support NAT traversal (NAT-T) with AH.
* NAT-T only works with ESP, because:
* AH includes the original IP header in its integrity check, which breaks when NAT modifies the IP address.
* ESP works with NAT-Tsince it does not include the original IP header in its integrity check.
* Why is this statement false?
* AH does not support NAT-T, soAH+ESP cannot be used in NAT traversal scenarios.

SYN scanning requires a fully established TCP connection and is recorded in system logs.
- A. TRUE
- B. FALSE
Answer: B
Explanation:
Comprehensive and Detailed Explanation:
* SYN scanning is a stealthy TCP scanning technique used by attackers to detect open ports.
* How SYN scanning works:
* The attacker sends aSYN packetto a target port.
* If the port isopen, the target responds with aSYN-ACK.
* Instead of completing the handshake with anACK, the attacker sends anRST (reset) packet, leaving the connection half-open.
* Why is this statement false?
* SYN scanning does NOT establish a full connection (three-way handshake).
* It may not always be recorded in system logs, depending on firewall settings.

A screenshot of a computer screen AI-generated content may be incorrect.
HCIP-Security References:
* Huawei HCIP-Security Guide# Bandwidth Management & Traffic Control Policies
* Huawei QoS Configuration Guide# Traffic Classification, Policing, and Queue Scheduling
1##Step 1: Traffic Classification and Bandwidth Policy Matching
* The firewallfirst classifies trafficusing predefined bandwidth policies.
* These policies match traffic based on criteria such assource/destination IP, application type, and protocol.
* This step ensures that each type of traffic is categorized correctly before applying bandwidth restrictions.
2##Step 2: Traffic Processing Based on Bandwidth Policies
* Once traffic is classified,the firewall enforces bandwidth limits and security actions:
* Traffic exceeding the assigned bandwidth is discarded or throttled.
* Service connection limits are enforced to prevent excessive connections per user or application.
3##Step 3: Queue Scheduling and Priority Handling
* If trafficexceeds the available bandwidth, the firewallprioritizes high-priority trafficusing queue scheduling mechanisms.
* Techniques likeWeighted Fair Queuing (WFQ) and Priority Queuing (PQ)ensure thatcritical traffic (e.g., VoIP, business applications) is prioritized over less important traffic (e.g., downloads, streaming).
