Questions # 21:

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.

A DHCP server must be enabled on the border nodes to allow subnets to span multiple fabric edges.

C.

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

D.

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

Questions # 22:

Question # 22

Refer to the exhibit. A company has some offices that are connected via dark fiber in New York. A network architect must optimize the network design based on the EIGRP routing protocol.

Options:

A.

Configure stub areas on non-edge routers.

B.

Implement network summarization on edge routers.

C.

Use different EIGRP processes on edge routers.

D.

Configure route filtering on non-edge routers.

Options:

A.

Use update-source to specify the Loopback interface.

B.

Use next-hop-serf attributes only for routes that are learned from eBGP peers.

C.

Configure the eBGP TTL to support eBGP multihop.

D.

Use maximum-paths to install multiple paths in the routing table.

Questions # 27:

An engineer is designing a multicast network for a company specializing in VoD content. Receivers are across the Internet, and for performance reasons, the multicast framework close to the receivers within each AS. For high availability, if the sources in one AS are no longer available, the receivers of that AS must be able to receive the VoD content from sources in another AS. Which feature must the design include?

Options:

A.

Bidirectional PIM

B.

SSM

C.

Anycast RP

D.

MSDP

Expert Solution

mapping EIDs to RLOCs

B.

encapsulating user traffic in a VXLAN header including the SGT

C.

registering new endpoints in the HTDB

D.

transporting IP packets between edge nodes and border nodes

Expert Solution
Questions # 29:

Which two statements about VRRP object tracking are true? (Choose two)

Options:

A.

The priority of a VRRP device can change in accordance with the up or down status of a VRRP object

B.

The VRRP interface priority must be manually configured by the administrator

C.

A VRRP group can track only one object at a time

D.

VRRP can track the status of interfaces and routes

E.

VRRP supports only interface tracking

Expert Solution
Questions # 30:

Which two statements describe source trees in a multicast environment? (Choose two.)

Options:

A.

Source trees guarantee the minimum amount of network latency for forwarding multicast traffic

B.

Source trees create an optimal path between the source and the receivers

C.

Source trees use a single common root placed at some chosen point in the network

D.

Source trees can introduce latency in packet delivery

E.
