Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q244-Q249):

NEW QUESTION # 244
Which of the following descriptions about the next-hop application of routing in BGP are correct? (Multiple choice)

A. By default, when BGP advertises imported IGP routes to IBGP peers, it changes the next hop attribute to its own interface address
B. You can use the peer X.X.X.Xnext-hop-local command to modify the next hop address when advertising routes to lBGP peers
C. The next hop attribute of BGP is different from that of IGP, not necessarily the IP address of the adjacent device
D. By default, no next-hop iteration routing policy is configured

Answer: B,C

NEW QUESTION # 245
See the following figure. RTA, RTB, RTC, and RTD are in the same AS and establish IBGP peer relationships through direct links. RTB an RTC are route reflectors (RRs), RTA and RTC are the RR clients of RTB, and RTB and RTD are the RR clients of RTC. If RTA advertises the route 10.1.1.0/24 to the BGP process, the Originator ID of the BGP route received by RTD is------------------.

Answer:

Explanation:
1.1.1.1
Explanation:
The Originator ID in a BGP route represents the Router ID of the device that originally advertised the route into the BGP domain. Since RTA originates the route 10.1.1.0/24 into the BGP process, the Originator ID in the route received by RTD will be set to 1.1.1.1 .

NEW QUESTION # 246

NEW QUESTION # 248
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. 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.
B. RSTP deletes three port states and adds two port roles.
C. The non-root switch running RSTP sends configuration BPDUs at the interval specified by the Hello timer, which is performed independently by each device.
D. RSTP reduces five port states to three port states based on user traffic forwarding and MAC address learning.

Answer: A

Explanation:
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 .
