An architect is working on a design to connect a company's main site to several small to
medium-sized remote branches. The solution must include redundant WAN links, but the
customer has a limited budget and wants the ability to increase the link speed easily in the
future. QoS will not on the branch routers so there is no need for consistent end-to-end
QoS. Which solution does the architect propose?

A.

dual-homed WAN MPLS with single edge router

B.

dual-homed Internet with a single edge router running a site-to-site VPN topology

C.

dual-homed WAN MPLS and Internet links via dual edge routers

D.

dual-homed Internet with dual edge routers running a hub-and-spoke VPN topology

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

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.

An engineer must propose a QoS architecture model that allows an application to inform
the network of its traffic profile and to request a particular type of service to support its
bandwidth and delay requirements. The application requires consistent and dedicated
bandwidth end to end. Which QoS architecture model meets these requirements?

A.

DiffServ

B.

LLQ

C.

WRED

D.

IntServ

An engineer must design a scalable QoS architecture that allows the separation of the traffic into classes on predefined business requirements. The design must also utilize the
differentiated services code points as the QoS priority descriptor value and support at least
10 levels of classification. Which QoS technology should the engineer include in the design?

A.

RSVP

B.

Diffserv

C.

Best effort

D.

Interserv

When a network is designed using IS-IS protocol, which two circuit types are supported?
(Choose two.)

A.

nonbroadcast multiaccess

B.

multiaccess

C.

point-to-multipoint

D.

nonbroadcast

E.

point-to-point

Which two statements about VRRP advertisements are true? (Choose two.)

A.

They are sent from the master router and standby routers.

B.

They include VRRP timer information.

C.

They are sent only from the master router.

D.

They include priority information.

E.

They are sent every three seconds by default.

Refer to the exhibit. An engineer must design an automatic failover solution. The solution
should allow HSRP to detect a WAN 1 failure and initiate an automatic failover, making
router R2 the active HSRP router. Which two solutions should the engineer choose?
(Choose two.)

A.

Implement Enhanced Object Tracking on router R1

B.

use a floating static route

C.

Implement IP SLA on router R1

D.

Implement PBR on router R1

E.

use IP source routing

Refer to the exhibit. An architect must create a stable and scalable EIGRP solution for a
customer. The design must:
•conserve bandwidth, memory, and CPU processing
•prevent suboptimal routing
•avoid any unnecessary queries
Which two solutions must the architect select? (Choose two.)

A.

route summarization

B.

prefix lists

C.

distribute lists

D.

stub routing

E.

static redistribution

Refer to the exhibit. The connection between SW2 and SW3 is fiber and occasionally
experiences unidirectional link failure. An architect must optimize the network to reduce the
change of layer2 forwarding loops when the link fails. Which solution should the architect
include?

A.

Utilize 8PDU filter on SW3.

B.

Utilize loop guard on SW2

C.

Utilize BPDU guard on SW1

D.

Utilize root guard on SW1

An engineer is tasked with designing a dual BGP peering solution with a service provider.
The design must meet these conditions:
The routers will not learn any prefix with a subnet mask greater than /24.
The routers will determine the routes to include in the routing table based on the
length of the mask alone.
The routers will make this selection regardless of the service provider
configuration.
Which solution should the engineer include in the design?

A.

Use a route map and access list to block the desired networks, and apply the route map to BGP neighbors inbound.

B.

Use a route map and prefix list to block the desired networks, and apply the route map to BGP neighbors outbound.

C.

Use an IP prefix list to block the desired networks and apply the IP prefix list to BGP neighbors outbound.

D.

Use an IP prefix list to block the desired networks and apply the IP prefix list to BGP
neighbors inbound.
