Refer to the exhibit. What information about the interfaces on the Main_Campus router is true?
A. The LAN interfaces are configured on different subnets.
B. Interface FastEthernet 0/0 is configured as a trunk.
C. The Layer 2 protocol of interface Serial 0/1 is NOT operational.
D. The router is a modular router with five FastEthernet interfaces.
E. Interface FastEthernet 0/0 is administratively deactivated.
Answer: B
Explanation:
Interface fa0/0 breaks into sub interface and Main_Campus router is connected with switch via fa0/0 .Subinterfaces configured with different subnet mask so its seem switch has multiple vlans and allow communication between vlan , router and inter-vlan we need to make a trunk port.So B will be the correct answer.
B seems to be correct answer, but it doesn’t exclude that A is incorrect. May be both A and B.
Actually I think it is A
It is B. The SERIAL interfaces are configured on different subnets and the question refers to the main campus switch only
f0/0 is not configured at all so B is incorrect
A is correct
I think B is correct.
Without configuring a f0/0 as a trunk, protocol of f0/0.1 ~0.4 won’t be up.
Yes B is correct and I believe that is the expected answer.
However, A isn’t entirely incorrect either. Not for the reasons mentioned in previous reply but because there are some sub interfaces that are probably connecting to the LAN, with IPs assigned. IP assignment would have failed if they were on the same subnet.
Actually, reading through the question again, B is wrong. You don’t configure trunks on routers. Trunks are configured only on switch ports. A is the correct answer.
Ehmm..My bad. There’s no edit option for the comments. Please discard the previous reply.
B is the correct answer.
