Given this, which of the following statements are true?

Options:

A) The OSPF neighbor relationship between R1 and R2 is not affected.
B) An OSPF neighbor relationship can be established between R1 and R3.
C) An OSPF neighbor relationship can be established between R3 and R4.
D) An OSPF neighbor relationship can be established between R2 and R4.

2. On a BGP/MPLS IP VPN network, which of the following are carried when a PE advertises VPNv4 routes?

A) RD
B) Export target
C) Import target
D) IPv4 prefix

3. A network engineer checks LLDP neighbor information on R1. The output is shown below.
Which of the following statements are true?
LLDP Output:
yaml

Management address type: IPv4
Management address: 192.168.1.1
Expired time: 107s

A) The sysname of the peer device is R2.
B) The management IP address of the peer device is 192.168.1.1.
C) The VLAN ID of the peer device is 1.
D) The interface number of the peer device is GE0/0/0.

4. On the network shown in the figure, IS-IS runs on R1, R2, R4, and R5, and the area ID is 49.0001. IS-IS runs on R3 and R6, and the area ID is 49.0002. The import-route isis level-2 into level-1 command is configured on R2 and R5. In AS 65000, R1, R3, R4, and R6 each establish IBGP peer relationships with R2 and R5. R2 and R5 are RRs, and R1, R4, R3, and R6 are clients. The IBGP peer relationships are established using Loopback0. The IP address of Loopback0 on each router is 10.0.X.X/32, and the router ID is 10.0.X.X, where X is the number of the router. R1 and R4 import the external route 192.168.1.0/24 to BGP through the import- route command, and R3 and R6 import the external route 192.168.2.0/24 to BGP through the import-route command.
