Question 1

Under which circumstance does BGP ignore the best-path algorithm after receiving multiple routes to a destination?

Awhen the routes are synchronized

Bwhen the route's first hop has a different AS number

Cwhen the routes have local-preference values less than 100

Dwhen the route's next hop is unreachable

Answer : D

Question 2

Refer to the exihibit.

Refer to the exhibit. An engineer is scripting ACLs to handle traffic on the given network. The engineer must block users on the network between R1 and R2 from leaving the network through R5. but these users must still be able to access all resources within the administrative domain. How must the engineer implement the ACL configuration?

AConfigure an ACL that permits traffic to any internal address, and apply it to the R5 interfaces to R3 and R4 in the egress direction

BConfigure a permit any ACL on the R1 interface to R2 in the egress direction, and a deny any ACL on the interface in the ingress direction

CConfigure an ACL that permits traffic to all internal networks and denies traffic to any external address, and apply it to the R2 interface to R1 in the ingress direction.

DConfigure an ACL that denies traffic to any internal address and denies traffic to any external address, and apply it to the R5 interfaces to R3 and R4 in the ingress direction

Answer : C

In the given scenario, the goal is to restrict users on the network between R1 and R2 from accessing the external network through R5, while still allowing them access to all resources within the administrative domain. The correct approach is to configure an Access Control List (ACL) that permits traffic to all internal networks and denies traffic to any external address. This ACL should be applied to the R2 interface that connects to R1 in the ingress direction. By doing so, traffic originating from users between R1 and R2 destined for external networks will be blocked, while internal traffic will be allowed.

Question 3

What is the purpose of DS-Lite technology?

AIt enables networks to pass encapsulated IPv4-in-IPv6 traffic over the ISP backbone.

BIt allows network administrators to implement shared IPv4 addresses between the ISP and its customers.

CIt allows an ISP to service IPv6 networks over an IPv4-enabled ISP backbone.

DIt allows network administrators to transition a network to IPv6 while maintaining IPv4 support.

Answer : A

Question 4

Refer to the exhibit.

Refer to the exhibit. MPLS is running in the network with OSPF as the IGP. Full routes are shared between the routers, and each connected link has an MPLS neighbor relationship. A network engineer must update the network configuration so that it will maintain LDP neighbor relationships if a directly connected link goes down. Which action must the engineer take as part of the process?

AImplement Unified MPLS to unify the OSPF areas.

BImplement MPLS OAM with BFD on the links.

CImplement LDP sync on links with a greater risk of faults.

DImplement LDP session protection on the network.

Answer : D

Question 5

What are two features of stateful NAT64? (Choose two.)

AIt uses address overloading.

BIt provides 1:N translations, so it supports an unlimited number of endpoints.

CIt requires IPv4-translatable IPv6 address assignments.

DIt requires the IPv6 hosts to use either DHCPv6-based address assignments or manual address assignments.

EIt provides 1:1 translation, so it supports a limited number of endpoints.

Answer : A, B

Question 6

Refer to the exhibit.

If RC is a stub router, which entry must be injected so that it will send traffic outside the OSPF domain?

Avirtual link between RB and RC

Bsham link

Cmore specific route

Ddefault route

Answer : D

If RC is a stub router in an OSPF network, it requires a default route to be injected so that it can send traffic outside the OSPF domain. In OSPF, stub routers do not have any routes external to the OSPF domain in their routing tables. To allow these routers to reach networks outside of their OSPF domain, a default route should be injected into the stub area by the Area Border Router (ABR). This allows all routers in the stub area, including RC, to forward traffic for unknown destinations to the ABR, which then forwards it appropriately.Reference: Implementing and Operating Cisco Service Provider Network Core Technologies source documents or study guide

Question 7

Refer to the exhibit.

A network engineer is implementing an LDP-based MPLS solution to enable packet flow between the two bank sites The engineer was given two requirements

* LDP peering must stay up when there is a link failure between R3 and R6

* LDP peering must not flap when there is a link failure between R5 and R6

Which action meets these requirements?

AEnable Link LDP on R4 and R6

BReset the LDP session between R4 and R6

CConfigure LDP Session Protection on R4

DImplement an LDP targeted session with R4 on R6

Answer : C
