NEW QUESTION # 165
In the OSPF protocol, inter-area route calculation involves only Router LSA, Network LSA, and Summary LSA.
Answer: A
Explanation:
Inter-area route calculation in OSPF involves Summary LSAs (Type 3) for summarizing routes across areas and ASBR Summary LSAs (Type 4) for locating ASBRs. While Router LSAs and Network LSAs describe the internal structure of an area, they do not directly participate in inter-area route calculation. Thus, the statement that only Router, Network, and Summary LSAs are involved is false .
NEW QUESTION # 166
The 802.1X authentication system supports two authentication methods, EAP relay and EAP termination, to complete the authentication between the device and the authentication server. Which of the following descriptions about the two authentication methods are wrong? (Multiple choice)
Answer: B,C
NEW QUESTION # 167
On an IS-IS network, all routers generate LSPs. Which of the following types of information isnotcontained in the LSPs generated by pseudonodes?
Answer: B
Explanation:
Apseudonodein IS-IS is a logical representation of a broadcast network segment (e.g., Ethernet) where theDesignated Intermediate System (DIS)generates an LSP on behalf of the LAN.
Pseudonode LSPs contain:
Interface information(i.e., the interface that connects to the pseudonode) Neighbor information(adjacencies with other routers on the LAN) Protocol information(e.g., supported address families) However,route information is not containedin LSPs generated by pseudonodes because routing information is advertised in theLSPs generated by the routers themselves, not the pseudonode.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"Pseudonode LSPs contain information about the broadcast link, including interface and neighbor data. They do not advertise routing entries." (Chapter: IS-IS Advanced Features - Section: DIS and Pseudonodes)
NEW QUESTION # 168
In addition to a route reflector, the confederation is another method that reduces the number of IBGP connections in an AS.
Which of the following statements are true about the confederation technology? (Choose all that apply)
Answer: A,C,D
Explanation:
A is correct- Confederations arespecifically designed for large-scale BGP deploymentswhere a full IBGP mesh is impractical.
B is correct- Sub-ASs within a confederation establishEBGP-like connectionsbetween each other but behave like IBGP within the overall AS. These sub-ASsdo not require full-mesh inside the confederation, but EBGP rules are followed between sub-ASs.
C is false-Not all devices need to be reconfigured. Devices within the same sub-AS retain normal IBGP behavior and minimal changes.
D is correct- Confederation istransparent to external peers, so thelogical topology remains the samefrom outside the AS.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"BGP confederation divides an AS into multiple sub-ASs. EBGP-like sessions are established between sub- ASs, while reducing IBGP mesh complexity. The external AS still sees the AS as one unit." (Chapter: BGP Scalability Enhancements - Section: Confederation)
NEW QUESTION # 169
On an IS-IS network, each router can generate LSPs.
Which of the following events trigger the generation of a new LSP?
Answer: A,B,D
Explanation:
IS-IS routers generate new Link State Packets (LSPs) under the following conditions:
Interface Status Changes: When IS-IS interfaces go up or down, the link state changes, triggering LSP updates.
Periodic Updates: IS-IS periodically regenerates LSPs to ensure link-state information remains synchronized across the network.
Interface Metric Changes: Any modification to interface costs results in a new LSP to reflect the updated cost in the network.
