What protocols are used to configure trunking on a switch?
  1. VLAN Trunking Protocol
  2. VLAN
  3. 802.1Q
  4. ISL
1 and 2
3 and 4
1 only
2 only
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
VTP is not right because it has nothing to do with trunking except that it sends VLAN information across a trunk link. 802.1Q and ISL are used to configure trunking on a port.

You have an interface on a router with the IP address of 192.168.192.10/29. What is the broadcast address the hosts will use on this LAN?
192.168.192.15
192.168.192.31
192.168.192.63
192.168.192.127
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
A /29 (255.255.255.248) has a block size of 8 in the fourth octet. This means the subnets are 0, 8, 16, 24, etc. 10 is in the 8 subnet. The next subnet is 16, so 15 is the broadcast address.

The Corporate router receives an IP packet with a source IP address of 192.168.214.20 and a destination address of 192.168.22.3. Looking at the output from the Corporate router, what will the router do with this packet? 
Corp#sh ip route
[output cut]
R    192.168.215.0 [120/2] via 192.168.20.2, 00:00:23, Serial0/0
R    192.168.115.0 [120/1] via 192.168.20.2, 00:00:23, Serial0/0
R    192.168.30.0 [120/1] via 192.168.20.2, 00:00:23, Serial0/0
C    192.168.20.0 is directly connected, Serial0/0
C    192.168.214.0 is directly connected, FastEthernet0/0
The packet will be discarded.
The packet will be routed out the S0/0 interface.
The router will broadcast looking for the destination.
The packet will be routed out the Fa0/0 interface.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
Since the routing table shows no route to the 192.168.22.0 network, the router will discard the packet and send an ICMP destination unreachable message out interface FastEthernet 0/0, which is the source LAN where the packet originated from.

A network administrator needs to configure a router with a distance-vector protocol that allows classless routing. Which of the following satisfies those requirements?
IGRP
OSPF
RIPv1
EIGRP
IS-IS
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
In this question, we're calling EIGRP just plain old distance vector. EIGRP is an "advanced" distance-vector routing protocol, sometimes called a hybrid routing protocol because it uses the characteristics of both distance-vector and link-state routing protocols.

You get a call from a network administrator who tells you that he typed the following into his router: 
Router(config)#router ospf 1
Router(config-router)#network 10.0.0.0 255.0.0.0 area 0
He tells you he still can't see any routes in the routing table. What configuration error did the administrator make?
The wildcard mask is incorrect.
The OSPF area is wrong.
The OSPF Process ID is incorrect.
The AS configuration is wrong.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
The administrator typed in the wrong wildcard mask configuration. The wildcard should have been 0.0.0.255.

You connect a host to a switch port, but the new host cannot log into the server that is plugged into the same switch. What could the problem be?
The router is not configured for the new host.
The VTP configuration on the switch is not updated for the new host.
The host has an invalid MAC address.
The switch port the host is connected to is not configured to the correct VLAN membership.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
This question is a little vague, but the best answer is that the VLAN membership for the port is not configured.

You want to create a standard access list that denies the subnet of the following host: 172.16.50.172/20. Which of the following would you start your list with?
access-list 10 deny 172.16.48.0 255.255.240.0
access-list 10 deny 172.16.0.0 0.0.255.255
access-list 10 deny 172.16.64.0 0.0.31.255
access-list 10 deny 172.16.48.0 0.0.15.255
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
First, you must know that a /20 is 255.255.240.0, which is a block size of 16 in the third octet. Counting by 16s, this makes our subnet 48 in the third octet, and the wildcard for the third octet would be 15 since the wildcard is always one less than the block size.

Which of the following is true when describing an anycast address?
Packets addressed to a unicast address are delivered to a single interface.
Packets are delivered to all interfaces identified by the address. This is also called one-to-many addresses.
This address identifies multiple interfaces and the anycast packet is only delivered to one address. This address can also be called one-to-one-of-many.
These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
Anycast addresses identify multiple interfaces, which is the same as multicast; however, the big difference is that the anycast packet is only delivered to one address, the first one it finds defined in the terms of routing distance. This address can also be called one-to-one-of-many.

What two multicast addresses does OSPFv3 use?
  1. FF02::A
  2. FF02::9
  3. FF02::5
  4. FF02::6
2 only
3 only
1 and 3
3 and 4
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
Adjacencies and next-hop attributes now use link-local addresses, and OSPFv3 still uses multicast traffic to send its updates and acknowledgments with the addresses FF02::5 for OSPF routers and FF02::6 for OSPF designated routers. These are the replacements for 224.0.0.5 and 224.0.0.6, respectively.
