Which of the following parameters are not mandatory during the configuration of a BGP peer?
A. Peer IP address
B. description
C. as-number
D. password
答案：B,D
解題說明：
The mandatory parameters for BGP peer configuration are the peer IP address (peer ip-address) and AS number (as-number). A password is optional for MD5 authentication, and a description is an optional comment for reference. These are not required for establishing the peer relationship .
問題 #1187
Which of the following descriptions about Filter-Policy are correct? (Multiple choice)
A. In the distance vector protocol, because routing information is passed between devices, Filter-Policy can directly
B. Filtering In the link state routing protocol, the routing table is generated through the LSDB, so Filter- Policy essentially filters the LSA in the LSDB
C. Filter-Policy can be used on both OSPFv2 and OSPFv3
D. In the distance vector protocol, if you want to filter out the route from the upstream device to the downstream device, you need to configure filter-policy export on the downstream device.
答案：A,C
問題 #1188
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)
A. This technology is applicable to large-scale networks.
B. All member devices in a confederation need to be reconfigured.
C. The logical topology does not need to be changed when a confederation is used.
D. Special EBGP connections are established among sub-ASs in a confederation, and the sub-ASs need to be fully meshed.
答案：A,C,D
解題說明：
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)

問題 #1190
In an IPv4 address space, Class D addresses are used for multicast. Among Class D addresses, which of the following is the permanent group address range reserved for routing protocols?
A. 224.0.0.0 to 224.0.0.255
B. 224.0.1.0 to 231.255.255.255
C. 239.0.0.0 to 239.255.255.255
D. 232.0.0.0 to 232.255.255.255
答案：A
解題說明：
Permanent Group Addresses for Routing Protocols
* The range 224.0.0.0 to 224.0.0.255 is reserved for local network protocols, including routing protocols.
Examples include OSPF (224.0.0.5/6) and RIP (224.0.0.9).
HCIP-Datacom-Core Reference
* Reserved multicast address ranges are detailed in the multicast configuration sections.
