NEW QUESTION # 372
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: C,D
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 # 374
See the network shown in the following figure.
R1 and R2 run IS-IS and establish an adjacency. IS-IS is enabled on Loopback0 of R2 but disabled on Loopback3 of R2. The configurations shown in the figure are performed in the IS-IS process of R2. Which of the following statements are true?
Answer: B,D
Explanation:
In the provided configuration, IS-IS is enabled on Loopback0 but not on Loopback3 of R2. As a result, R2 will advertise the route 10.0.2.2/32 (from Loopback0) to R1 through IS-IS. However, the route 10.0.2.3/32 will not be advertised because IS-IS is not enabled on that loopback interface. The import-route direct command does not override this behavior .
