Huawei HCIP-Datacom-Core Technology V1.0 Sample Questions (Q308-Q313):

NEW QUESTION # 308
During BGP route summarization configuration, the keyword can be used to suppress all specific routes so that only the summary route is advertised. The summary route carries the Atomic-aggregate attribute rather than the community attributes of specific routes.

Answer:

Explanation:
suppress-spec-map
Explanation:
Understanding BGP Route Summarization:
* In Border Gateway Protocol (BGP), route summarization is a technique used to aggregate multiple specific prefixes into a broader summary prefix. This reduces the size of routing tables and improves routing efficiency.
* Summarization helps to hide unnecessary details from other parts of the network while still maintaining connectivity.
* HCIP-Datacom-Core Technology Training Material (BGP Route Summarization).
Suppressing Specific Routes:
When summarizing routes, the suppress-spec-map keyword is used to suppress specific prefixes so that only the summarized route is advertised.
The suppressed routes are not advertised to BGP peers; instead, only the summary route is propagated.
Reference: HCIP-Datacom Advanced Routing & Switching Technology (BGP Attributes and Summarization Techniques).
Atomic-Aggregate Attribute:
The summary route generated during BGP route summarization carries the Atomic-aggregate attribute. This attribute indicates that the summary route might not provide the exact path information available in the original specific routes.
Additionally, when using the suppress-spec-map option, the specific routes' attributes, such as community attributes, are not included in the summary route.
Reference: HCIP-Datacom-Core Technology Training Material (BGP Path Attributes).
Conclusion:
The suppress-spec-map keyword is used to suppress specific routes when performing BGP summarization.
The summarized route includes the Atomic-aggregate attribute but does not carry community attributes from the suppressed routes.

NEW QUESTION # 309
Regarding the description of IGMP Snooping-working mechanism, which is the correct?

A. When IGMP Snooping is not running, the multicast message will be broadcast on the second layer.
After running IGMP Snooping, the message will no longer be broadcast on the second layer, but will be multicast on the second layer.
B. If the host sends an IGMP leave message, the switch will add the host to the corresponding multicast table.
C. If the host sends an IGMP host report message, the switch will delete the multicast entry corresponding to the hos.t
D. The layer 2 switch establishes and maintains the PIM routing table on the layer 2 by continuously monitoring IGMP messages.

Answer: A

NEW QUESTION # 310

NEW QUESTION # 311
Which of the following descriptions about RSTP root protection are correct? (Multiple choice)

A. The port with root protection turned on will enter the error-down state after receiving the RST BDPU with a higher priority.
B. After a port with root protection enabled receives a higher-priority RST BPDU, if it does not continue to receive a higher-priority RST BPDU for a period of time, it will return to the normal forwarding state.
C. It is recommended to enable it on the switch at the edge of the network
D. The root protection function will take effect when enabled on the root port.

Answer: B,C

NEW QUESTION # 312
Which of the following statements is false about the default processing of the next hop address when a BGP device advertises a route?

A. A BGP device does not change the next hop address of a route if the route is received from an IBGP peer and is to be sent to another IBGP peer.
B. When advertising a route to an EBGP peer, a BGP device sets the next hop address to the IP address of its interface connected to the peer.
C. When advertising a locally originated route to an IBGP peer, a BGP device sets the next hop address to the IP address of its interface connected to the peer.
D. When advertising a non-labeled route received from an EBGP peer to an IBGP peer, a BGP device changes the next hop address to the IP address of its interface connected to the IBGP peer.

Answer: D

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
Default Next Hop Behavior in BGP:
Locally Originated Routes (A):The next hop is set to the advertising router's interface IP address.
Routes Received from EBGP (B):The next hop is not changed when these routes are advertised to IBGP peers. (This makes Option B false.) Routes Advertised to EBGP (C):The next hop is set to the interface IP address of the advertising router.
Routes Advertised Between IBGP Peers (D):The next hop is not modified by default.
Incorrect Statement:
Option B is incorrect because the next hop of a non-labeled route received from an EBGP peer is not changed when it is advertised to IBGP peers.
