NEW QUESTION # 117

Answer: A
NEW QUESTION # 118
In IP multicast transmission, packets are transmitted from a source to a group of receivers. Which of the following statements are true about IP multicast technologies?
Answer: B,C
Explanation:
Comprehensive and Detailed In-Depth Explanation:
* IP Multicast vs. Broadcast:
* A. TRUE # Unlike broadcast, which sends data to all hosts in a subnet, multicast only sends data to interested receivers, preventing flooding.
* B. TRUE # Multicast optimizes bandwidth usage by sending a single copy of data, which is then replicated at network routers only when necessary.
* IP Multicast vs. Unicast:
* C. FALSE # Multicast does not improve security; it may expose data to unintended receivers if not properly controlled.
* D. FALSE # Multicast reduces the load on the source because a single data stream serves multiple receivers instead of sending individual unicast streams.
# Reference: Huawei HCIA-Datacom Study Guide, IP Multicast Principles and Benefits.
NEW QUESTION # 119
When multiple access channels are set for the same access requirement, the insecure access channels are not used and secure access channels are selected in normal cases.
Which of the following are secure access channels?
Answer: A,D
Explanation:
Secure access channels include protocols that encrypt the transmitted data to protect against interception or unauthorized access. HTTPS (HyperText Transfer Protocol Secure) ensures data encryption over web communications, while SFTP (Secure File Transfer Protocol) provides secure file transfer by utilizing SSH for data encryption. Telnet and SNMPv2, on the other hand, lack robust encryption and are considered insecure. Huawei security standards highlight the importance of encrypted communication to prevent data leaks.
NEW QUESTION # 120
Which of the following characteristics does the IS-IS protocol have? (Multiple choice)
Answer: A,C,D
NEW QUESTION # 121
By default, some security zones are created when Huawei firewalls are enabled. Which of the following security zones is created by users?
Answer: A
Explanation:
By default, Huawei firewalls create security zones such as Trust, Untrust, and Local. The DMZ (Demilitarized Zone) is a security zone explicitly created by users. A DMZ is used to isolate an internal network from the external one, providing an additional layer of security by placing public-facing services (e.
g., web servers) in this intermediary zone. This setup ensures that if a public-facing service is compromised, the internal network remains secure. Huawei Firewall configuration steps confirm this zoning principle, making DMZ creation an explicit user-driven action .
