Q21. - (Topic 3)
Which command would you configure globally on a Cisco router that would allow you to view directly connected Cisco devices?
A. enable cdp
B. cdp enable
C. cdp run
D. run cdp
Answer: C
Explanation:
CDP is enabled on Cisco routers by default. If you prefer not to use the CDP capability, disable it with the no cdp run command. In order to reenable CDP, use the cdp run command in global configuration mode. The “cdp enable” command is an interface command, not global.

Refer to the exhibit.
HostA cannot ping HostB. Assuming routing is properly configured, what is the cause of this problem?
A. HostA is not on the same subnet as its default gateway.
B. The address of SwitchA is a subnet address.
C. The Fa0/0 interface on RouterA is on a subnet that can't be used.
D. The serial interfaces of the routers are not on the same subnet.
E. The Fa0/0 interface on RouterB is using a broadcast address.
Answer: D
Explanation:
Now let’s find out the range of the networks on serial link: For the network 192.168.1.62/27:
Increment: 32
Network address: 192.168.1.32
Broadcast address: 192.168.1.63 For the network 192.168.1.65/27: Increment: 32
Network address: 192.168.1.64
Broadcast address: 192.168.1.95
-> These two IP addresses don’t belong to the same network and they can’t see each other.
Q23. - (Topic 7)
What are three factors a network administrator must consider before implementing Netflow
in the network? (Choose three.)
A. CPU utilization
B. where Netflow data will be sent
C. number of devices exporting Netflow data
D. port availability
E. SNMP version
F. WAN encapsulation
Answer: A,B,C
Explanation:
NetFlow has a reputation for increasing CPU utilization on your network devices. Cisco's performance testing seems to indicate that newer hardware can accommodate this load pretty well, but you will still want to check it out before you turn on the feature. Some symptoms of high CPU utilization are very large jitter and increased delay. Services running on the device may also be affected.
Another thing to keep in mind is the amount of data you're going to be sending across the network. Depending on how much traffic you have and how you configure it, the traffic can be substantial. For example, you may not want to send NetFlow data from a datacenter switch to a NetFlow collector on the other side of a small WAN circuit. Also bear in mind that the flows from aggregating large numbers of devices can add up.

Which feature can you implement to reserve bandwidth for VoIP calls across the call path?
A. PQ
B. CBWFQ
C. round robin
D. RSVP
Answer: D
Q25. - (Topic 8)
Which three circumstances can cause a GRE tunnel to be in an up/down state? (Choose three.)
A. The tunnel interface IP address is misconfigured.
B. The tunnel interface is down.
C. A valid route to the destination address is missing from the routing table.
D. The tunnel address is routed through the tunnel itself.
E. The ISP is blocking the traffic.
F. An ACL is blocking the outbound traffic.
Answer: B,C,D
Q26. - (Topic 5)
What is a valid HSRP virtual MAC address?
A. 0000.5E00.01A3
B. 0007.B400.AE01
C. 0000.0C07.AC15
D. 0007.5E00.B301
Answer: C
Explanation:
With HSRP, two or more devices support a virtual router with a fictitious MAC address and unique IP address. There are two version of HSRP.
+ With HSRP version 1, the virtual router’s MAC address is 0000.0c07.ACxx , in which xx is the HSRP group.
+ With HSRP version 2, the virtual MAC address if 0000.0C9F.Fxxx, in which xxx is the HSRP group.
Note: Another case is HSRP for IPv6, in which the MAC address range from 0005.73A0.0000 through 0005.73A0.0FFF.
Q27. - (Topic 8)
While troubleshooting a connection problem on a computer, you determined that the computer can ping a specific web server but it cannot connect to TCP port 80 on that server. Which reason for the problem is most likely true?
A. A VLAN number is incorrect.
B. A Route is missing
C. An ARP table entry is missing.
D. An ACL is blocking the TCP port.
Answer: D
Q28. - (Topic 5)
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.
Q29. CORRECT TEXT - (Topic 7)
CCNA.com has a small network that is using EIGRP as its IGP. All routers should be running an EIGRP AS number of 12. Router MGT is also running static routing to the ISP.
CCNA.com has recently added the ENG router. Currently, the ENG router does not have connectivity to the ISP router. All over interconnectivity and Internet access for the existing locations of the company are working properly.
The task is to identify the fault(s) and correct the router configuration(s) to provide full connectivity between the routers.
Access to the router CLI can be gained by clicking on the appropriate host.
All passwords on all routers are cisco.
IP addresses are listed in the chart below.
