Question # 50

Which design consideration must be made when dual WAN Edge routers are deployed at a branch site?

A.

Use BGP AS-path prepending to influence egress traffic and use MED to influence ingress traffic from the branch.

B.

HSRP priorities must match the OMP routing policy to prefer one WAN Edge over the other.

C.

Traffic must be symmetrical as it egresses the WAN Edges and returns from remote sites for DPI to function properly.

D.

Configure BFD between WAN Edge routers to detect sub-second link failures.

Question # 51

Refer to the exhibit. An engineer is designing an OSPF solution for a customer. The design must take into consideration:

    Application load balancers D. E. and F are in different geographical locations and are OSPF-enabled.

    Hosts A, B. and C connect to an application through the load balancers using IP address 10.1.1.1/32.

    In the event of a failure of one of the load balancers, hosts must still have access to the application.

Which solution must the engineer choose?

A.

All load balancers to be co-located in area 0.

B.

X, Y, and Z to be configured as different areas

C.

At least one load balancer to be in area 0.

D.

X, Y and Z to be configured as the same area

Question # 52

Which consideration must be made when designing a Cisco SD-Access fabric underlay?

A.

Subnets must be reduced to decrease latency.

B.

Up to six control planes are supported.

C.

The default MTU should be increased.

Question # 53

An architect must create a QoS solution for a customer to ensure that a 40 Mbps Internet connection is shared between four subnets based on these requirements:

* Each subnet must receive no less than 10 Mbps of download bandwidth during peak traffic times.

* A subnet can use up to 40 Mbps during nonpeak traffic times if the other subnets are idle.

* Download traffic must never experience a delay.

Which solution must the architect choose?

A.

rate-limiting and shaping

B.

bandwidth percentage and policing

C.

shaping and policing

D.

bandwidth percentage and rate-limiting

Question # 54

An ISP provides Layer 3 VPN service over MPLS to a customer with four branches and multiple CE routers at

each branch. To exchange the routes that are learned from the CE routers, which BGP address family should

the ISP activate among the PE routers?

A.

address-family multicast

B.

L2VPN EVPN

C.

VPNv4 unicast

D.

IPv4 unicast

Question # 55

What is the purpose of the fabric control plane in a Cisco SD-Access architecture?

A.

create, propagate, and enforce G6AC policies in the fabric

B.

create a transit node with BGP route reflector functionality

C.

extend multiple subnets to one RLOC

D.

create and resolve endpoint-to-location mapping
