Which of the following is NOT one of the reasons why BGP is used as the routing protocol in the data center?

  1. It is more efficient than link-state protocols like IS-IS and OSPF.
  2. BGP neighbors automatically discover each other.
  3. It is a well understood and mature routing protocol.
  4. It supports both IPv4 and IPv6.

Answer(s): A

Explanation:

BGP is not chosen because it is more efficient than link-state protocols; in fact, link-state protocols like IS-IS and OSPF generally provide faster convergence and more efficient route calculation. BGP is used in data centers mainly because it is mature, well understood, supports both IPv4 and IPv6, and offers flexible policy control.



Which of the following statements about the VXLAN tunneling in data centers is FALSE?

  1. VXLAN tunnel endpoints can be on hypervisors, leaf routers, or datacenter gateways.
  2. EVPN routes are exchanged between VXLAN tunnel endpoints.
  3. Each VXLAN tunnel endpoint is automatically assigned with a unique VNI value.
  4. VLXAN tunneling is used to provide Layer 2 connectivity between workloads over a common underlay network.

Answer(s): C

Explanation:

VXLAN tunnel endpoints (VTEPs) are configured with VNI (VXLAN Network Identifier) values, but these VNIs are not automatically assigned; they must be explicitly configured to define Layer 2

segments.



Which of the following statements about multi-homing in EVPN is FALSE?

  1. Type 1 Ethernet Auto-Discovery (A-D) EVPN route is used to support EVPN multi-homing.
  2. Type 4 Ethernet Segment (ES) EVPN route is used for designated forwarder (DF) election for an ES.
  3. The ES identifier (ESI) uniquely identifies an ES and it is locally significant for a particular leaf.
  4. The Ethernet Segment (ES) identifies a set of links that connects a host to one or more leafs.

Answer(s): C

Explanation:

The Ethernet Segment Identifier (ESI) uniquely identifies an Ethernet Segment (ES) globally across the EVPN domain, not just locally for a particular leaf.



Examine the exhibit.
What type of information is NOT included in the IMET route advertised by VTEP1?

  1. VXLAN network identifier (VNI)
  2. Flooding list
  3. Route distinguisher of VTEP1's MAC-VRF
  4. IP address of VTEP1

Answer(s): C

Explanation:

The IMET route includes the VNI, flooding list, and IP address of the originating VTEP, but it does not include the route distinguisher of the VTEP's MAC-VRF.
