問題 #175
Regarding multicast MAC addresses, which of the following statements are incorrect? (Multiple choice)

答案：B,C


問題 #176
When receiving a packet, a router matches the packet against ACL rules. The ACL matching result is either Matched or Unmatched. If the matching result is Unmatched, which of the following are possible causes?

答案：A,B,C

解題說明：
Comprehensive and Detailed In-Depth Explanation:
* When a packet is checked against an Access Control List (ACL), it is processed based on rule matches.
* "Unmatched" scenarios occur if:
* A. TRUE # The packet does not match any ACL rule.
* C. TRUE # No ACL is configured, so there are no rules to match.
* D. TRUE # An empty ACL exists, meaning no rules are defined.
* B is incorrect because if the packet matches a deny rule, it is "matched" and explicitly dropped, not "unmatched".
# Reference: Huawei HCIA-Datacom Study Guide, ACL Rule Matching and Processing Logic.


問題 #177
In IGMPv1, querier selection depends on a multicast routing protocol, such as PIM. In IGMPv2 and IGMPv3, the interface with the largest IP address acts as the querier.

答案：B

解題說明：
Comprehensive and Detailed Step-by-Step Explanation:
* IGMPv1 Querier Selection:
* In IGMPv1, there is no built-in querier election mechanism. Querier selection depends on the multicast routing protocol (e.g., PIM).
* IGMPv2 and IGMPv3 Querier Selection:
* In IGMPv2 and IGMPv3, the router interface with the largest IP address in the multicast group is selected as the querier.
* Correct Statement:
* The statement accurately describes the querier selection mechanisms in IGMP versions.

* HCIA-Datacom Study Guide, Chapter: IGMP Querier Mechanism

問題 #178
On an office network of an enterprise, OSPF is enabled on two directly connected routers. During adjacency establishment, the state machine stays in the 2-way state. Which of the following statements are not possible causes?

答案：B,D

解題說明：
OSPF State Machine:
OSPF adjacency progresses through several states: Down > Init > 2-Way > ExStart > Exchange > Loading > Full.
The 2-Way state indicates that routers have exchanged Hello packets but are not forming full adjacencies.
Possible Causes for Staying in the 2-Way State:
Hello Time Values Are Different (A): Mismatched Hello/Dead intervals prevent adjacency establishment.
Area IDs Are Different (B): OSPF routers must belong to the same area to establish adjacency.
Router IDs Conflict (C): While Router ID conflicts cause other issues, they do not result in the 2-Way state.
N-bit and E-bit Are the Same (D): Matching N-bit/E-bit values are normal and do not cause problems.


問題 #179
Which of the following mechanisms or techniques can VRRP be combined with to monitor uplink connectivity? (Multiple choice)

答案：A,B,C,D
