QUESTION 81  (Topic 1)

 

Which technique can you use to detect forwarding path failures at a uniform rate, and reconvergence times will be consistent and predictable when your routers are in the same broadcast domain?

 

A.

Enable BFD on your routers.

B.

Configure your routers with IP-SLA to ping the peer router.

C.

Configure your routers with IP-SLA and track to ping the peer and switch to a default route if the pings fail.

D.

Tune your routing protocol timers.

QUESTION 82  (Topic 1)

 

You are designing a network that will run EIGRP over a Metro Ethernet service that does not employ a link-loss technology. What will be the impact on convergence if there is a break in the end-to-end Layer 2 connectivity within the service provider network?

 

A.

The routers will immediately lose their adjacencies and converge.

B.

The routing protocol will not converge until the hold timers have expired.

C.

The switch ports connected to the router will go down and the routers will immediately converge.

D.

The VLAN on the switches will go inactive, the ports associated on the switch will go down, and the routers will immediately converge.

 

Answer: B

 

 

QUESTION 83  (Topic 1)

 

You are designing a multisite VPN solution for a customer and you are concerned with the additional overhead of point-to-point tunnels and the associated overlay routing with DMVPN. How does a GDOI-based VPN eliminate the additional tunnel and routing overhead found in DMVPN?

 

A.

The GDOI-based VPN requires overlaying a secondary routing infrastructure through the tunnels.

B.

In a GDOI-based VPN, all group members share a common security association.

C.

The GDOI-based VPN requires the provisioning of a complex connectivity mesh.

D.

The GDOI-based VPN leverages the routing protocol to find its peer for tunnel setup.

A service provider creates a network design that runs MPLS in its WAN backbone using OSPF as the IGP routing protocol. What would be two effects of additionally implementing MPLS-TE? (Choose two.)

 

A.

MPLS-TE is required to reroute traffic within less than 1 second in case of a link failure inside the backbone.

B.

MPLS-TE is required to route different MPLS QoS service classes through different paths.

C.

MPLS-TE and OSPF cannot be used together inside one MPLS network.

D.

MPLS-TE cannot use OSPF for the traffic path calculation.

E.

MPLS-TE is required to create backup paths independently from the IGP.

 

Answer: BE

 

 

QUESTION 85  (Topic 1)

 

When designing a large full mesh network running OSPF, how would you reduce LSA repetition?

 

A.

Elect a DR and BDR.

B.

Use access control lists to control outbound advertisements.

C.

Choose one or two routers to re-flood LSA information.

D.

Put each of the point-to-point links in your full mesh networking into a separate area.

 

Answer: C

 

 

QUESTION 86  (Topic 1)

 

Your design plan includes mutual redistribution of two OSPF networks at multiple locations, with connectivity to all locations in both networks. How is this accomplished without creating routing loops?

 

A.

Use route maps on the ASBRs to allow only internal routes to be redistributed.

B.

Use route maps on the ASBRs to allow internal and external routes to be redistributed.

C.

Use route maps on the ASBRs to set tags for redistributed routes.

D.

Use route maps on the ASBRs to filter routes with tags so they are not redistributed.

 

Answer: D

 

 

QUESTION 87  (Topic 1)

 

A planned EBGP network will use OSPF to reach the EBGP peer addresses. Which of these conditions should be avoided in the design that could otherwise cause the peers to flap continuously?

 

A.

An ACL blocks TCP port 179 in one direction.

B.

IP addresses used to peer are also being sent via EBGP.

C.

The OSPF area used for peering is nonbackbone (not area 0).

D.

The routers are peered by using a default route sent by OSPF.

 

Answer: B

 

 

QUESTION 88  (Topic 1)

 

A network designer is working with a company to improve convergence at the Layer 2 control plane and decides to use LACP. Which of these components does LACP use to create the system ID?

 

A.

LACP system priority and switch MAC address

B.

LACP port priority and switch MAC address

C.

LACP port priority and port number

D.

LACP system priority and port number

 

Answer: A

 

 

QUESTION 89  (Topic 1)

 

Which mechanism should be added to a network design to identify unidirectional Spanning Tree Protocol failures through BPDU loss?

 

A.

UDLD

B.

loop guard

C.

BPDU guard?

D.

root guard

 

Answer: B

 

 

QUESTION 90  (Topic 1)

 

A company is planning to connect its 30 sites with a VPLS WAN backbone. A router at each site should establish neighborships with all other routers using the OSPF routing protocol. Which three points must be considered regarding DR and BDR when different router platforms are used? (Choose three.)

 

A.

It is a best practice that the routers with the most powerful hardware should take the role of the DR and BDR.

B.

If the IP OSPF priority is the same for all routers, the highest loopback IP address and router ID will decide which routers will take the DR and BDR role during the selection process.

C.

To select the DR and BDR, the IP OSPF priority must be set to a higher value than the default value at the DR and BDR during the selection process.

D.

To select the DR and BDR, the IP OSPF priority must be set to a lower value than the default value at the DR and BDR during the selection process.

E.

The role for the DR and BDR will be selected when a new OSPF router comes up.

F.

To force two routers to become a DR and a BDR, the IP OSPF priority can be set to zero at all other OSPF routers.
