About PIM-Description of He1lo message in SM, what is wrong?

A. at P1M- In the SM network, the newly started multicast router needs to useHello message to discover neighbors and maintain neighborsresidential relationship

B. Used periodically between routersHello, keep in touch

C. pass throughHe11o message elects DR in multi-router network segment

D. Hello packets are sent to the multicast address 224.0.0.5

정답: D

문제2

the following aboutThe establishment process of LDP LSP, which description is correct?

A. The LSP establishment process is actually the process of binding the FEC to the label and advertising the binding to the upstream LSR of the LSP.

B. Label releaseIn the DoD mode, for a specific FEC, the LSR performs label allocation and distribution without obtaining a label request message from the upstream.

C. When the network topology change causes the next hop neighbor to change, using the free label retention mode, the LSR can directly use the label sent by the original non-optimal next hop neighbor to quickly rebuild the LSP. Liberal requires more memory and tab space.

D. By default, LSFor the same FEC, the received label mapping can only come from the optimal next hop, not from the non-optimal next hop.

정답: A,C

문제10

What is the meaning of the display current-configuration I include vlan command?

A. View all configurations that contain the keyword "VLAN"

B. Check the IP address of the VLANIF interface

C. Check the physical interface information bound under each LAN

문제11

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. Only by changing the configuration of Gigabitethernet1/0/2 to be consistent with Gigabitethernet1/0/1, the two can join the same aggregation group

D. Because of different link types, Gigabitethernet1/0/1 and Gigabitethernet1/0/2 cannot join the same aggregation group

정답: A

문제12

When deploying MPLS/BGP IP VPN, regarding the use of BGP to exchange routing information between PE-CE, which of the following descriptions is wrong?

A. When BGP is used to exchange routing information between PE and CE, there is no need to import private network routes into BGP on PE.

B. When BGP is used to exchange routing information between PE and CE, if the autonomous systems where the two VPN sites are located use the same private AS number, the AS number replacement function can be used to replace the received AS number with any specified AS number. The As number in the private network route, to prevent the route from being discarded due to repeated AS numbers

C. In the Hub & Spoke scenario, when Hub-CE and Hub-PE use IGP, Spoke-PE and Spoke-CE cannot use EBGP

D. In the case of CE multi-homing, enabling the BGP AS number replacement function may cause routing loops. BGP So can be used to prevent routing loops in VPN sites.
