TROUBLE TICKET STATEMENT:
“The implementation group has been using the test bed to do a ‘proof-of-concept’ that required both client 1
and client 2 to access the Web Server at 209.65.200.241. After several changed to interface status,
network addressing, routing schemes and layer 2 connectivity, at trouble ticket has been opened indicating
that client 1 cannot ping the 209.65.200.241 (internet Server)”
Client 1 is able to ping 10.1.1.2 but not 10.1.1.1. Initial troubleshooting shows that R1 does not have any
OSPF neighbors or any OSPF routes
Configuration on R1:

On which device is the fault condition located?
A. R1
B. R2
C. DSW1
D. Client1
Answer: A
Explanation/Reference:
Explanation:
As you will see, the problem in this situation is with OSPF on R1. It is missing the "ip ospf authentication
message-digest" command on the Serial0/0/0/0.12 interface.

Fault Condition is related to which technology?
A. NAT
B. IPV4 OSPF
C. Static Routing
D. Switch to Switch Connectivity
Answer: B
Explanation/Reference:
Explanation:
The problem in this situation is with OSPF on router 1. It is missing the "ip ospf authentication message-
digest" command on the Serial0/0/0/0.12 interface. The problem statement tells us that the two routers are
not able to become OSPF neighbors.

What is the solution of the fault condition?
A. enable OSPF Authentication on the S0/0/0 interface using the ip ospf authentication message-digest
command
B. ip ospf authentication message-digest command has to be added under the OSPF routing process
C. A static route to 10.1.1.4 must be added on R1
D. ipnat outside must be added on S0/0/0/0.12
Answer: A
Explanation/Reference:
Explanation:
R2 is correctly configured for OSPF authentication, including the "ip ospf authentication message-digest"
command listed properly under the sub-interface Serial0/0/0.12. R1 is missing this command.

HSRP has been configurationured between DSW1 and DSW2. DSW1 is configurationured to be active
router but it never becomes active even though the HSRP communication between DSW1 and DSW2 is
working.
Configuration on DSW1

Configuration on R4
interface loopback0

On which device is the fault condition located?
A. R4
B. DSW2
C. DSW1
D. R3
Answer: C
Explanation/Reference:
Explanation:
In this case we know that the problem is with HSRP and that DSW1 will not become the active router.
Since we know that HSRP communication is working between DSW1 and DSW2, we can deduce that the
problem must be with DSW1.
