The customer will manage the device using both IPv4 and IPv6. Which two components should be used to meet these requirements? (Choose two.)
A) mgmt0 interface
B) SSH protocol
C) SNMP
D) SVI interface
E) Telnet protocol

Question 12

Which element is the main functional component of the architecture that separates the internal fabric and the external network that connects sites when VXLAN EVPN is deployed multisite?
A) border leaf
B) service leaf
C) border gateway
D) service gateway

Accepted Answer

The border gateway is the main functional component that separates the internal fabric from the external network in a VXLAN EVPN multisite deployment. It handles the routing and forwarding between different VXLAN segments and external networks.

Question 13

An engineer must design a VXLAN EVPN network. The solution should optimize broadcast, unknown unicast, and multicast (BUM) and short BUM replication, and use PIM anycast RP. Which solution should be included in the design?
A) head-end replication
B) PIM sparse mode
C) PIM dense mode
D) ingress replication

Accepted Answer

Question 14

What is a design consideration when implementing FSPF?
A) Routes are based on the domain ID.
B) Routes are based on the distance vector protocol.
C) FSPF runs only on F Ports.
D) FSPF runs on a per-chassis basis.

Accepted Answer

FSPF (Fabric Shortest Path First) uses the domain ID to determine routes in a Fibre Channel network.

Question 16

A network engineer designs a Cisco Nexus data center network for a client-server farm using a pair of Nexus 9000 Series Switches in a vPC setup.

A) PAgP mode desirable
B) LACP mode auto
C) LACP mode active
D) PAgP mode auto

Accepted Answer

LACP mode active ensures that the Nexus switches actively initiate the negotiation process with the server, which is required in this design.
