Which one of the following is true regarding VLANs?
Two VLANs are configured by default on all Cisco switches.
VLANs only work if you have a complete Cisco switched internetwork. No off-brand switches are allowed.
You should not have more than 10 switches in the same VTP domain.
VTP is used to send VLAN information to switches in a configured VTP domain.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
Switches do not propagate VLAN information by default; you must configure the VTP domain. VLAN Trunking Protocol (VTP) is used to propagate VLAN information across a trunk link.

How does a host on an Ethernet LAN know when to transmit after a collision has occurred?
  1. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.
  2. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
  3. You can improve the CSMA/CD network by adding more hubs.
  4. After a collision, the station that detected the collision has first priority to resend the lost data.
  5. 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.

1,3 and 4
2 and 5
Your Answer: Option
(Not Answered)
Correct Answer: Option
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.

You need to subnet a network that has 5 subnets, each with at least 16 hosts. Which classful subnet mask would you use?
255.255.255.192
255.255.255.224
255.255.255.240
255.255.255.248
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
You need 5 subnets, each with at least 16 hosts. The mask 255.255.255.240 provides 16 subnets with 14 hosts-this will not work. The mask 255.255.255.224 provides 8 subnets, each with 30 hosts. This is the best answer.

What is the problem with an interface if you type show interface serial 0 and receive the following message? "Serial0 is administratively down, line protocol is down."
The keepalives are different times.
The administrator has the interface shut down.
The administrator is pinging from the interface.
No cable is attached.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
If an interface is shut down, the show interface command will show the interface as administratively shut down. (It is possible that no cable is attached, but you can't tell that from this message.)

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.

Which two of the following commands will place network 10.2.3.0/24 into area 0?
  1. router eigrp 10
  2. router ospf 10
  3. network 10.0.0.0
  4. network 10.2.3.0 0.0.0.255 area0
  5. network 10.2.3.0 0.0.0.255 area 0
1 and 4
2, 4, and 5
2 and 5
3 and 4
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
To enable OSPF, you must first start OSPF using a Process ID. The number is irrelevant; just choose a number from 1 to 65,535 and you're good to go. After you start the OSPF process, you must configure any network that you want advertised via OSPF using wildcards and the area command. Statement (4) is wrong because there must be a space after the parameter area and before you list the area number.

Which of the following access lists will allow only HTTP traffic into network 196.15.7.0?
access-list 100 permit tcp any 196.15.7.0 0.0.0.255 eq www
access-list 10 deny tcp any 196.15.7.0 eq www
access-list 100 permit 196.15.7.0 0.0.0.255 eq www
access-list 110 permit ip any 196.15.7.0 0.0.0.255
access-list 110 permit www 196.15.7.0 0.0.0.255
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
The first thing to check in a question like this is the access-list number. Right away, you can see that the second option is wrong because it is using a standard IP access-list number. The second thing to check is the protocol. If you are filtering by upper-layer protocol, then you must be using either UDP or TCP; this eliminates the fourth option. The third and last answers have the wrong syntax.

What command will permit SMTP mail to only host 1.1.1.1?
access-list 10 permit smtp host 1.1.1.1
access-list 110 permit ip smtp host 1.1.1.1
access-list 10 permit tcp any host 1.1.1.1 eq smtp
access-list 110 permit tcp any host 1.1.1.1 eq smtp
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
When trying to find the best answer to an access-list question, always check the access-list number and then the protocol. When filtering to an upper-layer protocol, you must use an extended list, numbers 100-199 and 2000-2699. Also, when you filter to an upper-layer protocol, you must use either tcp or udp in the protocol field. If it says ip in the protocol field, you cannot filter to an upper-layer protocol. SMTP uses TCP.

In Cisco's Unified Wireless Solution, what is the split-MAC architecture?
The split-MAC architecture uses MAC addresses to create a forward/filter table and break up collision domains.
The split-MAC architecture allows the splitting of 802.11 protocol packets between the AP and the controller to allow processing by both devices.
The split-MAC architecture uses MAC addresses on the wireless network and IP addresses on the wired network.
The split-MAC architecture uses MAC addresses to create a forward/filter table and break up broadcast domains.
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
The split-MAC architecture allows the splitting of 802.11 protocol packets between the Cisco LWAPP-based AP, which handles real-time portions of the protocol, and the WLAN controller, which handles those items that are not time sensitive.

Which of the following is true when describing a unique local address?
Packets addressed to a unicast address are delivered to a single interface.
These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.
These are like private addresses in IPv4 in that they are not meant to be routed.
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:
These addresses are meant for nonrouting purposes like link-local, but they are almost globally unique so it is unlikely they will have an address overlap. Unique local addresses were designed as a replacement for site-local addresses.

frame-relay arp
frame-relay map
frame-relay interface-dci
frame-relay lmi-type
Your Answer: Option
(Not Answered)
Correct Answer: Option
Explanation:
If you have a router in your Frame Relay network that does not support IARP, you must create Frame Relay maps on your router, which provide known DLCI-to-IP address mappings.
