Q4. - (Topic 8)
On which type of device is every port in the same collision domain?
A. a router
B. a Layer 2 switch
C. a hub
Answer: C
Explanation: Collision domainA collision domain is, as the name implies, a part of a
network where packet collisions can occur. A collision occurs when two devices send a packet at the same time on the shared network segment. The packets collide and both devices must send the packets again, which reduces network efficiency. Collisions are often in a hub environment, because each port on a hub is in the same collision domain. By contrast, each port on a bridge, a switch or a router is in a separate collision domain.

Which option is a valid IPv6 address?
A. 2001:0000:130F::099a::12a
B. 2002:7654:A1AD:61:81AF:CCC1
C. FEC0:ABCD:WXYZ:0067::2A4
D. 2004:1:25A4:886F::1
Answer: D
Explanation:
An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits (two octets). The groups are separated by colons (:). An example of an IPv6 address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334. The leading 0’s in a group can be collapsed using ::, but this can only be done once in an IP address.

What levels will be trapped if the administrator executes the command router(config)# logging trap 4 (Choose four)
A. Emergency
B. Notice
C. Alert

Q9. - (Topic 7)
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.
R1 does not form an OSPF neighbor adjacency with R2. Which option would fix the issue?
A. R1 ethernet0/1 is shutdown. Configure no shutdown command.
B. R1 ethernet0/1 configured with a non-default OSPF hello interval of 25; configure no ip ospf hello-interval 25.
C. R2 ethernet0/1 and R3 ethernet0/0 are configured with a non-default OSPF hello
interval of 25; configure no ip ospf hello-interval 25.
D. Enable OSPF for R1 ethernet0/1; configure ip ospf 1 area 0 command under ethernet0/1.
Answer: B
Explanation:
Looking at the configuration of R1, we see that R1 is configured with a hello interval of 25 on interface Ethernet 0/1 while R2 is left with the default of 10 (not configured).
