- B . Router-LSA
- C . Inter-Area-Router-LSA

A network engineer is checking LLDP neighbor information on R1. Which of the following descriptions are correct? (Multiple choice)

- A . The management IP address of the peer device is 192.168.1.1
- B . The interface of the peer device is coded as GE0/0/0

Which of the following descriptions about OSPFv3 are correct? (Multiple choice)
- A . OSPFv3 Router LSA and Network LSA do not contain IP addresses
- B . In broadcast, NBMA, and P2MP networks, neighbors are no longer identified by IP addresses, but only by Router IDs.
- C . OSPFv3 supports multiple processes on a link

An enterprise network is shown in the figure. If CE2 is dual-owned by PE2 and PE3, a Type 5 LSA routing loop may occur. The loop can be prevented by setting the route-tag command on PE2 and PE3 devices. When the Route Tag of the route received by PE3 is the same as the local configuration, the route will be ignored.

- A . True
- B . False
MPLS determines the upstream and downstream relationship based on the data forwarding direction. The MPLS label message is sent from the upstream LSR and received and processed by the downstream LSR. Similarly, the release of MPLS labels is also distributed one by one from upstream to downstream.
- A . True
- B . False
The file information shown in the figure exists on the R2 device. When the network engineer uses the "dir | exclude 1" command to view the file information, which of the following files will be seen?

- A . 4.zip
- B . 3.dat
- C . 1.cfg
- D . 2.cfg
In the OSPF network shown in the figure, the link cost value has been marked in the figure. R1 has enabled OSPF IP FRR and configured the "maximum load-balancing 1" command in the OSPF process. Which of the following is the backup outbound interface for R1 to reach 10.0.3.3/32?

- A . GE0/0/2
- B . GE0/0/1
- C . GE0/0/3
- D . No backup path

- A . True
- B . False
There are multiple types of MAC address entries on the switch. Which of the following types of entries can discard messages by matching the source MAC address of the received message, thereby achieving the purpose of filtering out illegal users.
- A . Static MAC address table
- B . Business MAC address table
- C . Dynamic MAC address table
- D . Blackhole MAC address table
