Exam B

QUESTION 1Client is able to ping 10.1.1.2 but 10.1.1.1. Initial troubleshooting shows that R1 does not have any OSPFneighbors or any OSPF routes.

Configuration on R1:

router ospf 1log-adjacency-changesnetwork 10.1.1.0 0.0.0.3 area 12default-information originate always!interface Serial0/0/0/0.12 point-to-pointip address 10.1.1.1 255.255.255.252ip nat insideip ospf message-digest-key 1 md5 TSHOOT


router ospf 1log-adjacency-changesnetwork 10.1.1.0 0.0.0.3 area 12!interface Serial0/0/0/0.12 point-to-pointip address 10.1.1.2 255.255.255.252ip ospf authentication message-digestip ospf message-digest-key 1 md5 TSHOOT

1.On which device is the fault condition located?2. What is the solution of the fault condition?3. Fault Condition is related to which technology?

Exhibit:

A. R1B. R2C. DSW1D. Client1E. ip ospf authentication message-digest command has to be added on S0/0/0/0.12F. ip ospf authentication message-digest command has to be added under the OSPF routing processG. A static route to 10.1.1.4 must be added on R1H. ip nat outside must be added on S0/0/0/0.12I. NAT

J. OSPFK. Statis RoutingL. Switch to Switch Connectivity

Correct Answer: AEJSection: (none)Explanation


QUESTION 2Client 1 is able to ping 209.65.200.226 but not the Web Server at 209.65.200.241. Initial troubleshootingshows and R1 does not have any BGP routes. R1 also does not show any active BGP neighbor.

In the above ticket R1 and all others are able to ping 209.65.200.226 but not the Web Server only. This isbecause R1 is directly connected to 209.65.200.226 and BGP is not required in order to ping directlyconnected network and as soon as R1 knows about 209.65.200.224 network all other devices are also ableto ping 209.65.200.226, since they are coming to R1 for any unknown route, because of default routepropagate through R1′s OSPF (using ‘default-information originate always’ command). However WebServer is not accessible until BGP configured properly between R1 and ISP(209.65.200.226) because onlythen R1 will receive the information about Web Server’s network.

Following are the symptoms of above ticket:

1- No one is able to ping Web Server.2- Client 1 and all others can ping upto 209.65.200.226.3- ‘sh ip route BGP’, you will not see any BGP route.4- ‘sh ip bgp neighbor’ on R1, you will not see any active BGP neighbor.

1. Fault Condition is related to which technology?2. What is the solution of the fault condition?3. On which device is the fault condition located?

Exhibit:

A. EIGRPB. HSRPC. BGPD. OSPFE. R1F. DSW1G. R4H. R2I. Enable BGP synchronizationJ. Change neighbor 209.56.200.226 remote-as 65002 statement to neighbor 209.56.200.226 remote-

Correct Answer: CEKSection: (none)Explanation

Explanation/Reference:In this scenario you need to check bgp neighbotship "show ip bgp sum".The neighbor`s address in the neighbor command is wrong under router BGP (use ipv4 Layer 3).You need to delete the wrong neighbor statement and enter the correct neighbor address in the neighborcommand (change 209.56.200.226 to 209.65.200.226).

QUESTION 3Client 1 and Client 2 are not able to reach the WebServer 209.65.200.241. Initial troubleshooting showsthat DSW1, DSW2 and all the routers are able to reach the WebServer.


ip nat inside source list nat_pool interface s0/0/0/1 overload

1. What is the solution of the fault condition?2. Fault Condition is related to which technology?3. On which device is the fault condition located?

Exhibit:

A. Add permit 10.2.0.0 statement in nat_pool access-listB. Remove permit 10.1.0.0 statement from nat_pool access-listC. Change ip nat inside source list nat_pool interface Serial0/0/0/1 overload to ip nat inside source
