Question 1

Which consideration must be taken into account when using the DHCP relay feature in a Cisco SD-Access Architecture?

Options :

A :

DHCP-relay must be enabled on fabric edge nodes to provide the correct mapping of DHCP scope to the local anycast gateway.

B :

DHCP servers must support Cisco SD-Access extensions to correctly assign IPs to endpoints in an SD-Access fabric with anycast gateway.

C :

DHCP Option-82 must be enabled to map the circuit IP option to the access fabric node where the DHCP discover originated.

Answer: C

Question 2

Refer to the exhibit. An architect is designing a network that requires route redistribution. The design must prevent route feedback and the creation of routing loops. The OSPF domain is using default metrics, and the IS-IS domain is using narrow metrics. Which solution must the architect select?

Options :

A : Change the IS-IS administrative distance to 105.

B : Change the OSPF area to a nonbackbone stub area

C : Use route filtering with an ACL or prefix list.

D : Use route tagging with a route map.

Answer: D

Question 3

Which protocol is deployed through LAN automation to build node-to-node underlay adjacencies in SDA?

Options :

A : IS-IS

B : OLISP

C : OSPF

D : VXLAN

Answer: A

Question 4

A branch office has a primary L3VPN MPLS connection back to the main office and an IPSEC VPN tunnel that serves as backup. Which design ensures that data is sent over the backup connection only if the primary MPLS circuit is down?

Options :

A : Use EIGRP to establish a neighbor relationship with the main office via

B : L3VPN MPLS and the IPSEC VPN tunnel.

C :

Use BGP with the multipath feature enabled to force traffic via the primary path when available.

D :

Use static routes tied to an IP SLA to prefer the primary path while a floating static route points to the backup connection.

E : Use OSPF with a passive-interface command on the backup connection.

Answer: D

Question 5

Which routes does the overlay management protocol advertise in an SD-WAN overlay?

Options :
