A large data center needs to extend its Layer 2 connectivity and isolate tenants who might use the same VLAN IDs Which technology accomplishes this goal?
SPBM
Data Center Bridging (DCB)
Multi-VPN-Instance CE (MCE)
TRILL
Correct answer: A
Question 2
To provide redundancy, a company has multiple data centers that use server virtualization. What is a networking requirement for this scenario?
less bandwidth at the server access layer and more bandwidth at the distribution layer than in a non-virtualized network
physical network segmentation and isolation implemented at Layers 1 through 7
localized storage volumes that are isolated within each data center
extension of Layer 2 connectivity across the data centers
Correct answer: D
Question 3
Refer to the exhibit
The exhibit displays a company with two data centers that connect by using EVl. The company needs a redundant solution for routing traffic between the subnets.
What is the best way to accomplish this goal?
Run Virtual Router Redundancy Protocol (VRRP) on the data center subnets
Place the EVl tunnel interface on each IRF virtual device in a different VPN instance, and then set up routing on each device by using the same IP addresses.
Use TRILL on the EVl network.
Combine IRF 1 and IRF 2 into the same IRF virtual device, and set up routing on that device
