D.
Public AS numbers must be used
Answers
Suggested answer: A, C

Explanation:

A) In a multi-site data center design using EBGP (External Border Gateway Protocol), using the same AS (Autonomous System) number across all devices in all data centers can simplify the design and routing policies.

C) Private AS numbers can be used for an EBGP IP fabric in a multi-site data center environment. This is a common practice as these AS numbers are not intended to be used on the public internet and are suitable for internal network use.

Suggested answer: B, D, E

Explanation:

Any to any connectivity is a key advantage of using MPLS for data center interconnects (DCIs). It allows for flexible and efficient connectivity options between various data center locations.

Traffic engineering is another significant advantage. MPLS allows for the control and optimization of traffic flows within the network, providing enhanced performance and efficient use of network resources

D.
Decrease the number VXLANs used
Answers
Suggested answer: A

Explanation:

To accommodate the extra header information added by VXLAN, which can be 50 to 54 bytes, it's necessary to increase the MTU (Maximum Transmission Unit) on the physical interfaces connected to the VXLAN network. This ensures that the larger frames can be transmitted without fragmentation, maintaining efficient network performance.

In the exhibit, VM1 is part of the same VXLAN segment as VM3.

Which type of message will R1 initially send to R2 so that VM1 receives BUM traffic from VM3?
