NEW QUESTION 8
Refer to the exhibit. An engineer has been asked to redesign the traffic flow toward AS 111 coming from AS 500. Traffic destined to AS 111 network 91.7.0.0/16 should come in via AS 100. while traffic destined to all other networks in AS 111 should continue to use the existing path. Which BGP attributes are best suited to control this inbound traffic coming from BGP AS 500 Into the 91.7.0.0/16 network?

• A. Prepend AS path for the 91.7.0.0/16 network and set it for neighbor in AS 200.
• B. Use extended community for the 91.7.0.0/16 network, not advertising it to the bi-lateral peer.
• C. Use local preference on R1 for the networks that AS 500 advertises to AS 111.
• D. Set higher MED for neighbor in AS 100 to influence incoming traffic for the 91. 7.0.0/16 network.

Answer: A

NEW QUESTION 9
Refer to the exhibit. OSPF is running as the IGP to provide reachability to all AS100 networks. R3 and R4 are the current ABRs at the boundary of OSPF Area0 and Areal. Now BGP must be deployed within AS 100 because it will be receiving. Internet routes from its eBGP peers (the service provider) connected to R1 and R2.
What is an optimal solution for this deployment to configure BGP relationships and redistribute BGP learned routes into OSPF?

• A. R5 should be configured as a route reflector for R1, R2, R3 and R4. BGP routes must beredistributed at R1 and R2 into OSPF.
• B. Configuration should be set up with R1 and R2, and R3 in one sub AS, with and R4 in another,and redistribution at R1 and R2.
• C. A full mesh should be deployed between all the routers with mutual redistribution to take place atR1 and R2.
• D. R1, R2, R3 and R4 must be set up with a neighbor relationship with R5 only must not be a routereflector.

Answer: C

NEW QUESTION 10
An enterprise network has two core routers that connect to 200 distribution routers and uses fullmesh
IBGP peering between these routers as its routing method. The distribution routers are experiencing high CPU utilization due to the BGP process. Which design solution is the most cost effective?

• B. Increase the memory on the core routers
• C. Implement e BGP between the core and distribution routers
• D. Increase the memory on the distribution routers
• E. Increase bandwidth between the core routers

Answer: A

NEW QUESTION 11
Refer to the exhibit. A new high availability DB sever cluster is installed in the network.

These two servers require high bandwidth and low latency Layer 2 connectivity for database replication.
Which solution supports these requirements?

• A. Add two new links between SW1 and SW2 configured as LACP trunk with STP
• B. Add secondary links to REP segments 1 and 2
• C. Add two new links between SW1 and SW2 configured as REP segment 3
• D. Add two new links between SW1 and SW2 configured as REP segments 1 and 2 respectively

Answer: C

NEW QUESTION 12
Two enterprise networks must be connected together. Both networks are using the same private IP addresses.
The client requests from both sides should be translated using hide NAT (dynamic NAT) with the overload feature to save IF addresses from the NAT pools.
Which design addresses this requirement using only one Cisco I OS NAT router for both directions?

• A. This is not possible, because two Cisco IOS NAT routers are required to do dynamic NAT, withoverload in both directions.
• B. The ip nat inside and ip nat outside commands must be configured at the interfaces with theoverload option in both directions.
• C. The overload feature is the default and does not have to be configured.
• D. Two different NAT pools must be used for the ip nat inside source and the ip nat outside sourcecommands for the overload feature in both directions.
• E. The Nat Virtual interface must be used to achieve this requirement.

Answer: D
