Question 3

Which two statements describe EVPN-based VXLAN implementations? (Choose two.)

Accepted Answer

In an EVPN-based VXLAN implementation, the movement of a virtual host results in the dynamic remapping of the VTEP. This is because EVPN uses control plane signaling to dynamically discover and advertise MAC addresses across the BGP network. MAC addresses are not learned using multicast flooding (option C) as in traditional VXLAN implementations. Instead, MAC addresses are propagated using BGP updates (option D). There is no requirement for manual reconfiguration of the VTEP when a virtual host moves in an EVPN-based VXLAN network.

Question 4

You are asked to configure VXLAN for your data center using multicast to exchange VTEP information. In this scenario, which two configuration parameters must match on the VTEPs in the same VXLAN segment? (Choose two.)

Accepted Answer

For VXLAN to function properly, the multicast group used to exchange VTEP information should be the same on all VTEPs in the same VXLAN segment. Additionally, the VNI (VXLAN Network Identifier) should also be the same on all VTEPs in the same VXLAN segment. The VLAN ID and routing instance name are not relevant to VXLAN configuration; VXLAN operates at Layer 2 and is independent of Layer 3 routing and VLANs.

Question 5

Question 6

Referring to the exhibit, each node in the IP fabric is peering to its directly attached neighbor using EBGP. Each node is peering using physical interface IP addresses. Leaf 2 and Leaf 3 are advertising the 10.1.1/24 network into EBGP. Spine 2 must be configured so that it can load-share traffic destined to the 10 1.1/24 network over both next-hop A and next-hop B.  Which two actions must be performed to accomplish this task? (Choose two.)

Accepted Answer

Question 7

Which protocol replicates forwarding information between MC-LAG peers?

Accepted Answer

ICCP (Inter-Chassis Communication Protocol) is used to replicate forwarding information between MC-LAG (Multi-Chassis Link Aggregation Group) peers.

Question 8

You are creating a new EVPN and are asked to selectively accept certain MAC advertisement routes from your EVPN peers using VXLAN encapsulation. Which statement is correct in this scenario?

Accepted Answer

VRF import policies and community values can be used to selectively accept or reject MAC advertisement routes in EVPN by matching specific community values associated with the routes.

Question 18

You are building a new IP fabric data center underlay network and want to ensure predictable load-balancing behavior for traffic traversing the fabric. What are two approaches you should take to satisfy the requirement in this scenario? (Choose two.)

Accepted Answer

Ensuring every leaf node has an uplink to every spine node (C) provides consistent paths for load balancing. Having all spine devices as the same switch model (D) ensures uniformity in performance and capabilities, aiding predictable load balancing.
