Huawei HCIP-Datacom-Core Technology V1.0 認定 H12-821_V1.0 試験問題 (Q68-Q73):

質問 # 68
STP ensures a loop-free network but has a slow network topology convergence speed, affecting communication quality. RSTP has made some improvements based on STP.
Which of the following improvements is not included?

A. The non-root switch running RSTP sends configuration BPDUs at the interval specified by the Hello timer, which is performed independently by each device.
B. RSTP reduces five port states to three port states based on user traffic forwarding and MAC address learning.
C. RSTP deletes three port states and adds two port roles.
D. If a port does not receive configuration BPDUs from the upstream device within four Hello intervals, the switch considers that the negotiation with the neighbor fails.

正解：D

解説：
RSTP improves convergence by introducing changes to the BPDU handling mechanism and port roles. However, RSTP does not rely on a fixed timeout of four Hello intervals for negotiation failure. Instead, RSTP uses a more dynamic mechanism to detect topology changes. The other options describe valid RSTP improvements.

質問 # 69
Whether a non-edge port migrates to the Forvardin state is one of the criteria for RSTP to detect topology changes.

A. TRUE
B. FALSE

正解：A

質問 # 70
An administrator of a company modifies a user's access rights and authorization attributes and other parameters on the authentication server.
At this time, user A who has successfully passed 802.1x authentication will perform which of the following actions?

A. User A does not perform re-authentication and continues to be online normally
B. The device sends the reserved user authentication parameters to the server for re-authentication. If successful, the user: continue to go online normally
C. User A is directly offline without re-authentication
D. User A directly performs re-authentication, and if successful, it will continue to be online normally

正解：A

質問 # 71
In a large-scale WLAN network, when the VLAN Pool uses HASH to allocate VLANs, the number of users in each VLAN will be evenly divided.

A. TRUE
B. FALSE

正解：B

質問 # 72
A wireless access controller interface has both the DHCP server function and the DHCP relay function enabled.
So which of the following descriptions of the processing method of the wireless access controller are correct? (Multiple choice)

A. Prioritize using the local DHCP server to assign IP addresses
B. Only when the local server cannot assign an IP address, the remote server will be used to assign an IP address.
C. Use both the local DHCP server and the remote DHCP server to assign IP addresses
D. Prioritize using the remote DHCP server to assign IP addresses

正解：A、B

質問 # 73
