Q1. DRAG DROP - (Topic 4)
Drag the definition on the left to the correct term on the right. Not all definitions on the left will be used.
Answer:
Q2. - (Topic 3)
Scenario
Refer to the topology. Your company has decided to connect the main office with three other remote branch offices using point-to-point serial links.
You are required to troubleshoot and resolve OSPF neighbor adjacency issues between the main office and the routers located in the remote branch offices.
An OSPF neighbor adjacency is not formed between R3 in the main office and R6 in the Branch3 office. What is causing the problem?
A. There is an area ID mismatch.
B. There is a PPP authentication issue; the username is not configured on R3 and R6.
C. There is an OSPF hello and dead interval mismatch.
D. The R3 router ID is configured on R6.
Answer: D
Explanation:
Using the show running-config command we see that R6 has been incorrectly configured with the same router ID as R3 under the router OSPF process.
Q3. DRAG DROP - (Topic 5)
Drag the appropriate command on the left to the configuration task it accomplishes. (Not all options are used.)
Answer:

Q5. - (Topic 3)
Refer to the exhibit.
When running OSPF, what would cause router A not to form an adjacency with router B?
A. The loopback addresses are on different subnets.
B. The values of the dead timers on the routers are different.
C. Route summarization is enabled on both routers.
D. The process identifier on router A is different than the process identifier on router B.
Answer: B
Explanation:
To form an adjacency (become neighbor), router A & B must have the same Hello interval, Dead interval and AREA numbers
Q6. - (Topic 7)

Q8. - (Topic 3)
OSPF is configured using default classful addressing. With all routers and interfaces operational, how many networks will be in the routing table of R1 that are indicated to be learned by OSPF?
A. 2
B. 3
C. 4
D. 5
E. 6
F. 7
Answer: C
Explanation:
Although OSPF is configured using default classful addressing but OSPF is a link-state routing protocol so it will always send the subnet mask of each network in their advertised routes. Therefore R1 will learn the the complete subnets. Four networks list below will be in the routing table of R1:+ 172.16.2.64/30+ 172.16.2.228/30+ 172.16.2.232/30+ 172.16.3.0/24 Note: Other networks will be learned as “Directly connected” networks (marked with letter “C”)
Q9. - (Topic 5)
Refer to the exhibit.
A technician is troubleshooting a host connectivity problem. The host is unable to ping a server connected to Switch_A. Based on the results of the testing, what could be the problem?
A. A remote physical layer problem exists.
B. The host NIC is not functioning.
C. TCP/IP has not been correctly installed on the host.
D. A local physical layer problem exists.
Answer: D
Explanation:
Here we see that the host is able to ping its own loopback IP address of 127.0.0.1 and it’s own IP address of 10.0.0.35, so we know that the NIC is functioning and that the host’s TCP/IP stack is OK. However, it is not able to ping the IP address of its local default gateway, so we know that there is a local cabling problem between the switch and the router.
Q10. - (Topic 7)
Which statement about unicast frame forwarding on a switch is true?
A. The TCAM table stores destination MAC addresses
B. If the destination MAC address is unknown, the frame is flooded to every port that is configured in the same VLAN except on the port that it was received on.
C. The CAM table is used to determine whether traffic is permitted or denied on a switch
D. The source address is used to determine the switch port to which a frame is forwarded
Answer: B
