Huawei HCIE-Routing & Switching (Written) V3.0 認定 H12-261_V3.0 試験問題:

1. The switches SWA and SWB are connected together through 2 Ethernet links, and the switch SWA has the following interface configuration
[SWA]interface Gigabitethernet 1/0/1
[SWA-gigabitethernet1/0/1]port link-type trunk
[SWA-gigabitethernet1/0/1]port trunk allow-pass vlan 1 10 100
[SWA]interface Gigabitethernet 1/0/2
[SWA-gigabitethernet1/0/2]port link-type trunk
[SWA-gigabitethernet1/0/2]port trunk allow-pass vlan 1 10
Configure link aggregation to tie the two links together. If the configuration on SWB is correct, it can be known from the above information

A) After link aggregation is configured on both SWA and SWB, if the switches SWA and SWB enable MSTP, then the interface status of Gigabitethernet1/0/1 and Gigabitethernet1/0/2 in MSTP is the same
B) Gigabitethernet1/0/1 and Gigabitethernet1/0/2 can join the same aggregation group without changing the current configuration
C) Because of different link types, Gigabitethernet1/0/1 and Gigabitethernet1/0/2 cannot join the same aggregation group
D) Only by changing the configuration of Gigabitethernet1/0/2 to be consistent with Gigabitethernet1/0/1, the two can join the same aggregation group

2. Which of the following statements about MSTP is correct?

A) MSTP can realize load sharing of traffic between different VLANs
B) MSTP supports compatible operation with RSTP
C) The BPDU format of MSTP is the same as that of RSTP.
D) Compared with RSTP, MSTP has more port roles.

3. General VPUsers in N can only communicate with each other, but cannot communicate with Internet users, nor can they access the Internet. However, each site of the VPN may need to access the Internet. Which is the correct description for the realization method of VPN and Internet interconnection?

A) Implemented on the PE, the PE device is directed toThe CE sends a default route to the Internet and adds a default route to the Internet gateway in the VPN instance routing table.
B) Implemented on the user side, the implementation method is simple, the public network and private network routes are isolated, and it is safe and reliable.
C) Implemented on the user side, directlyCEs are connected to the Internet. Each user site can be independently connected to the Internet, that is, the CE of each site is configured with a default route to the Internet.
D) The implementation on PE is complicated and there are security risks. PE equipment may be affected by the Internet Dos attack.

4. Since BGP is an EGP routing protocol, BGP routing policies can only be deployed between EBGP neighbors.
The routing policy deployed between neighbors is invalid.

A) TRUE
B) FALSE

5. BGP4+ is running between the two routers, and the neighbor relationship is normal, but the BGP routing table of the local router does not have any neighbor routing entries. What are the following possible reasons?

A) Peer ignore is configured on the peer
B) The next hop address of the BGP routing entry is unreachable
C) The peer is configured with active-route-advertise
D) The routing entry in the peer BGP routing table is not optimal.
