- 6. You want to create a standard access list that denies the subnet of the following host: 172.16.198.94/19. Which of the following would you start your list with?
Options- A. access-list 10 deny 172.16.192.0 0.0.31.255
- B. access-list 10 deny 172.16.0.0 0.0.255.255
- C. access-list 10 deny 172.16.172.0 0.0.31.255
- D. access-list 10 deny 172.16.188.0 0.0.15.255 Discuss
- 7. How does a host on an Ethernet LAN know when to transmit after a collision has occurred?
- In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.
- In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
- You can improve the CSMA/CD network by adding more hubs.
- After a collision, the station that detected the collision has first priority to resend the lost data.
- After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.

- 9. Which of the following is true regarding VLANs?
Options- A. You must have at least two VLANs defined in every Cisco switched network.
- B. All VLANs are configured at the fastest switch and, by default, propagate this information to all other switches.
- C. You should not have more than 10 switches in the same VTP domain.
- D. VTP is used to send VLAN information to switches in a configured VTP domain. Discuss
- 10. A switch has been configured for three different VLANs: VLAN2, VLAN3, and VLAN4. A router has been added to provide communication between the VLANs. What type of interface is necessary on the router if only one connection is to be made between the router and the switch?

- B. 56Kbps Serial
- C. 100Mbps Ethernet
- D. 1Gbps Ethernet Discuss

Correct Answer: The highest IP address of any physical interface
Explanation:
At the moment of OSPF process startup, the highest IP address on any active interface will be the Router ID (RID) of the router. If you have a loopback interface configured (logical interface), then that will override the interface IP address and become the RID of the router automatically.
Correct Answer: 3, 4 and 6
Explanation:
RIPv1 and IGRP are true distance-vector routing protocols and can't do much, really-except build and maintain routing tables and use a lot of bandwidth! RIPv2, EIGRP, and OSPF build and maintain routing tables, but they also provide classless routing, which allows for VLSM, summarization, and discontiguous networking.
Correct Answer: 23
Explanation:
The IEEE 802.11h standard provides an addition 11 channels to the 802.11a standard's 12 non-overlapping channel for a total of 23 non-overlapping channels.
Correct Answer: 1, 3 and 5
Explanation:
Layer 2 features include address learning, forwarding and filtering of the network, and loop avoidance.
Correct Answer: NVRAM should be erased and the router restarted.
Explanation:
Before you start to configure the router, you should erase the NVRAM with the
erase startup-config command and then reload the router using the
reload command.
Correct Answer: access-list 10 deny 172.16.192.0 0.0.31.255
Explanation:
First, you must know that a /19 is 255.255.224.0, which is a block size of 32 in the third octet. Counting by 32, this makes our subnet 192 in the third octet, and the wildcard for the third octet would be 31 since the wildcard is always one less than the block size.
Correct Answer: 2 and 5
Explanation:
Once transmitting stations on an Ethernet segment hear a collision, they send an extended jam signal to ensure that all stations recognize the collision. After the jamming is complete, each sender waits a predetermined amount of time, plus a random time. After both timers expire, they are free to transmit, but they must make sure the media is clear before transmitting and that they all have equal priority.
Correct Answer: Inside local
Explanation:
The host on the private network before translation is considered to be an inside local host.
Correct Answer: VTP is used to send VLAN information to switches in a configured VTP domain.
Explanation:
Switches do not propagate VLAN information by default; you must configure the VTP domain. VLAN Trunk Protocol (VTP) is used to propagate VLAN information across a trunked link.
Correct Answer: 100Mbps Ethernet
Explanation:
Although you can use either 100Mbps or 1Gbps Ethernet, the 100Mbps is necessary at a minimum and is the best answer to this question. You need to trunk the link from the switch to the router to make this connection work with inter-VLAN communication.
