Q 
IPv6 unicast routing is running on a corporate router. Which of the following addresses would show up with the show ipv6 int brief command?
A.FF02::3c3d:0d:bdff:fe3b:0d80
B. FE80::3c3d:2d:bdff:fe3b:0d80
C. FE80::3c3d:0d:bdff:fe3b:0d80
D. FE80::3c3d:2d:ffbd:3bfe:0d80
A

B.FE80::3c3d:2d:bdff:fe3b:0d80 This can be a hard question if you don’t remember to invert the 7th bit of the first octet in the MAC address. Always look for the 7th bit when studying for the Cisco R/S, and when using eui-64, invert it. The eui-64 auto configuration then inserts an FF:FE in the middle of the 48 bit MAC address to create a unique IPv6 address.

Q

Which two statements describe the IP address 10.16.3.65/23 (choose two)
A. The subnet address is 10.16.3.0 255.255.254.0
B. The lowest host address in the subnet is 10.16.2.1 255.255.254.0
C. The last valid host address in the subnet is 10.16.2.254 255.255.254.0
D. The broadcast address of the subnet is 10.16.3.255 255.255.254.0
E. The network is not subnetted

A

B. The lowest host address in the subnet is 10.16.2.1 255.255.254.0
D. The broadcast address of the subnet is 10.16.3.255 255.255.254.0

The mask 255.255.255.254.0 (/23) used with a Class A address means that there are 15 subnet bits and 9 host bits. The block size in the third octet is 2 (256-254). So this makes the subnet a in the interesting octet 0,2,4,6,etc., all the way to 254. The host 10.16.3.65 is in the 2.0 subnet. The next subnet is 4.0 so the broadcast address for the 2.0 subnet is 3.255. The valid host addresses are 2.1 through 3.254

Q 
Which of the following is the following is the valid host range for the subnet on which the IP address 192.168.168.188 255.255.255.192 resides?
A. 192.168.168.129-190
B. 192.168.168.129-191
C. 192.168.168.128-190
D. 192.168.168.128-192
A

A. 192.168.168.129-190
256-192=64, so 64 is our block size. Just count in increments of 64 to find our subnet: 64+64=128. 128+64=192. The subnet is 128, the broadcast address is 191, and the valid host range is the numbers in between,or 129-190.

Q
  1. Your inside locals are not being translated to the inside global addresses. Which of the following commands will show you if your inside global a are allowed to use the NAT pool?
    ip nat pool Corp 198.18.41.129 198.18.41.134 netmask 255.255.255.248
    ip nat inside source list 100 int s0/0 Corp overload
    A. debug ip nat
    B. show access-list
    C. show ip nat translation
    D. show ip net statistics
A

B. show access-list
Once you create your pool, the command ip nat inside source must be used to say which inside locals are allowed to use the pool. In this question, we need to see if access list 100 is configured correctly ,if at all, so show access-list is the best answer.

A. A
B. B
C. C
D. D
A

A. A
Class A addressing provides 22 bits for host subnetting. Class B provides 16 bits , but only 14 are available for subnetting. Class C provides only 6 bits for subnetting.

21
Q 
There are three possible routes for a router to reach a destination network. The first route is from OSPF with a metric of 782. The second route is from RIPv2 with a metric of 4. The third is from EIGRP with a composite metric of 201514560. Which route will be installed by the router in its routing table?
A. RIPv2
B. EIGRP
C. OSPF
D. All three
A

B. EIGRP
Only the EIGRP route will be placed in the routing table because the EIGRP has the lowest administrative distance (AD), and that is always used before metrics.

22
Q

Which one of the following is true regarding VLANs?
A. Two VLANs are configured by default on all Cisco routers.
B. VLANs only work if you have a complete Cisco switched internetwork. No off-brand switches are allowed.
C. You should not have more than 10 switches in the same VTP domain.
D. You need to have a trunk link configured between switches in order to send information about more than one VLAN down the link

A

D. You need to have a trunk link configured between switches in order to send information about more than one VLAN down the link
Switches send information about only one VLAN down a link unless it is configured as a trunk link.

23
Q 
How many broadcast domains are created when you segment a network with a 12-port switch?
A. 1
B. 2 
C. 5
D. 12
A

A. 1

By default, switches break up collision domains on a per-port basis but are one large broadcast domain

24
Q 
What protocols are used to configure trunking on a switch? (Choose two)
A. VLAN Trunking protocol
B. VLAN
C. 802.1q
D. ISL
A

C. 802.1q
D. ISL
VLAN Trunking Protocol (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 encapsulations are used to configure trunking on a port.

25
Q

What is a stub network?
A. A network with more than one exit point
B. A network with more than one exit and entry point
C. A network with only one entry and no exit point
D. A network that has only one entry and exit point

A

D. A network that has only one entry and exit point
Stub networks have only one connection to an internetwork. Default routes should be set on a stub network loops may occur; however, there are exceptions to this rule.

Q 
Which of the following is the best summarization of the following networks: 192.168.128.0 through 192.168.159.0?
A. 192.168.0.0/24

If you start at 192.168.128.0 and go through 192.168.159.0, you can see that this is a block of 32 in the third octet. Since the network address is always the first one in the range , the summary address is 192.168.128.0. What mask provides a block of 32 in the third octet? The answer is 255.255.225.0 or /19
