Question # 91

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. The network has hierarchical addressing between 10 and 12 routers in each office. Routing convergence time must be at the minimum. What must the network architect do to reduce the query range?

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.

Question # 92

Refer to the exhibit. An engineer proposed this solution for a company that requires a loop-free. Layer 2 network design. The network will run 802.1W, and all links will be 1 Gbps. If all interfaces are up as point- to-point adjacencies, what are the expected port end states based on the design?

Options:

A.

Eth1/2 on SW2 and SW3 will be in a Desg FWD state


B.

Eth1/3 on SW2 and SW3 will be m an Attn BLK state


C.

Eth1/2 on SW3 and SW4 will be m an Attn BLKbtate.


D.

Eth1/1 on SW1 and SW2 will be in a Root FWD state.

Options:

A.

distribute-list


B.

policy-based routing


C.

leak-map


D.

route tagging

Questions # 94:

Question # 94

Refer to the exhibit. A network engineer working for a private service provider with an employee ID: 4670:71:451 must design a BGP solution based on:

    All traffic originating from AS100 must pass through AS200 to reach the NTP and DHCP server

    When a link failure occurs between R3 and R4, traffic must follow the R2-R9 link to reach the NTP and DHCP server.

Which solution must the design include?

Options:

A.

Routers R3 and R10 advertise an IGP metric into BGP during redistribution in both directions.


B.

Router R6 influences the paths of R9 and R11 to the DC with a higher AS-PATH value.


C.

Routers R3 and R10 advertise a lower local preference for outgoing traffic and a higher AS-PATH value for incoming traffic.


D.

Router R3 applies a local preference of 200 for R1. R2. R9. and R11 routers to reach the data center.

Questions # 95:

An architect is creating a migration strategy for a large organization in which the choice made by the application between IPv6 and IPv4 is based on the DNS request. Which migration strategy does the architect choose?

Options:

A.

AFT for public web presence


B.

host-initiated tunnels


C.

dual stack


D.

site-to-site IPv6 over IPv4 tunnels


Expert Solution
Questions # 96:

Question # 96

Refer to the exhibit. Which two solutions maximize the use of the links between the core and distribution layers? (Choose two.)

Options:

A.

use multiple equal-cost links


B.

use an IGP


C.

use HSRP


D.

use R-PVSTP+


E.

use multiple unequal-cost links


Expert Solution
Questions # 97:

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

Options:

A.

underlay, MPLS, and overlay


B.

primary, backup, and load-balanced


C.

prefix, TLOC, and service


D.

Internet, MPLS, and backup


Expert Solution
Questions # 98:

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

Options:

A.

to maintain the endpoint database and mapping between endpoints and edge nodes


B.

to detect endpoints in the fabric and inform the host tracking database of EID-to-fabric-edge node bindings


C.

to identify and authenticate endpoints within the network fabric


D.

to act as the network gateway between the network fabric and outside networks


Expert Solution
Questions # 99:

Question # 99

Refer to the exhibit. An architect must design an OSPF solution for an enterprise customer. The design must meet these requirements:

·Limit the link flap impact to Area-1 and Area-2.

·Any link failure must have minimal impact on voice and video traffic.

·Which two OSPF solutions must the architect include in the design? (Choose two.)

Options:

A.

Reduce the frequency of OR and BOR elections.


B.

increase hello and how timer.


C.

Tune LSA and SPF throttling timers


D.

Enable manual route summarization and configure all nonbackbone areas as stub networks.


E.

Advertise default routes from the backbone to nonbackone areas.


Expert Solution
Questions # 100:

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

Options:

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
