Cisco 100-101 Online Questions & Answers

• Question 191:

  A switch receives a frame on one of its ports. There is no entry in the MAC address table for the destination MAC address. What will the switch do with the frame?

  A. drop the frame
  B. forward it out of all ports except the one that received it
  C. forward it out of all ports
  D. store it until it learns the correct port
  B. forward it out of all ports except the one that received it

  ---

  Understanding this concept is prime for understanding that when switch receives the data frame from the host not having the MAC address already in the MAC table, it will add the MAC address to the source port on the MAC address table and sends the data frame. If the switch already has the MAC address in it's table for the destination, it will forward the frame directly to the destination port. If it was not already in it's MAC table, then they frame would have been flooded out all ports except for the port that it came from.

• Question 192:

  Which network device functions only at Layer 1 of the OSI model?

  

  A. B. C.
  B

  ---

  Most hubs are amplifying the electrical signal; therefore, they are really repeaters with several ports. Hubs and repeaters are Layer 1 (physical layer) devices.

• Question 193:

  Refer to the exhibit.

  

  How many collision domains are shown?

  A. one
  B. two
  C. three
  D. four
  E. six
  F. twelve
  B. two

  ---

  Hubs create single collision and broadcast domains.

• Question 194:

  

  

  Select three options which are security issues with the current configuration of SwitchA. (Choose three.)

  A. Privilege mode is protected with an unencrypted password
  B. Inappropriate wording in banner message
  C. Virtual terminal lines are protected only by a password requirement
  D. Both the username and password are weak
  E. Telnet connections can be used to remotely manage the switch
  F. Cisco user will be granted privilege level 15 by default
  A. Privilege mode is protected with an unencrypted password
  B. Inappropriate wording in banner message
  D. Both the username and password are weak

  ---

  This answer can be done by simulation only, don't know user name password and banner message etc

• Question 195:

  On a live network, which commands will verify the operational status of router interfaces? (Choose two.)

  A. Router# show interfaces
  B. Router# show ip protocols
  C. Router# debug interface
  D. Router# show ip interface brief
  E. Router# show start
  A. Router# show interfaces
  D. Router# show ip interface brief

  ---

  Both these commands will show the current status of the interfaces, either in show or debug mode both will display the information.

• Question 196:

  Which three statements are correct about RIP version 2? (Choose three)

  A. It uses broadcast for its routing updates.
  B. It supports authentication.
  C. It is a classless routing protocol.
  D. It has a lower default administrative distance then RIP version 1.
  E. It has the same maximum hop count as RIP version 1.
  F. It does not send the subnet mask any updates.
  B. It supports authentication.
  C. It is a classless routing protocol.
  E. It has the same maximum hop count as RIP version 1.

• Question 197:

  Which IP addresses are valid for hosts belonging to the 10.1.160.0/20 subnet? (Choose three.)

  A. 10.1.168.0
  B. 10.1.176.1
  C. 10.1.174.255
  D. 10.1.160.255
  E. 10.1.160.0
  F. 10.1.175.255
  A. 10.1.168.0
  C. 10.1.174.255
  D. 10.1.160.255

  ---

  All IP address in IP ranges between: 10.1.160.1 and 10.1.175.254 are valid as shown below Address:

  10.1.160.0 00001010.00000001.1010 0000.00000000 Netmask: 255.255.240.0 = 20 11111111.11111111.1111 0000.00000000 Wildcard: 0.0.15.255 00000000.00000000.0000 1111.11111111

  Which implies that: Network: 10.1.160.0/20 00001010.00000001.1010 0000.00000000 HostMin: 10.1.160.1 00001010.00000001.1010 0000.00000001 HostMax: 10.1.175.254 00001010.00000001.1010 1111.11111110 Broadcast: 10.1.175.255 00001010.00000001.1010 1111.11111111

• Question 198:

  What OSPF command, when configured, will include all interfaces into area 0?

  A. network 0.0.0.0 255.255.255.255 area 0
  B. network 0.0.0.0 0.0.0.0 area 0
  C. network 255.255.255.255 0.0.0.0 area 0
  D. network all-interfaces area 0
  A. network 0.0.0.0 255.255.255.255 area 0

• Question 199:

• Question 200:

  How does a switch differ from a hub?

  A. A switch does not induce any latency into the frame transfer time.
  B. A switch tracks MAC addresses of directly-connected devices.
  C. A switch operates at a lower, more efficient layer of the OSI model.
  D. A switch decreases the number of broadcast domains.
  E. A switch decreases the number of collision domains.
  B. A switch tracks MAC addresses of directly-connected devices.

  Some of the features and functions of a switch include:

  A switch is essentially a fast, multi-port bridge, which can contain dozens of ports. Rather than creating two collision domains, each port creates its own collision domain. In a network of twenty nodes, twenty collision domains exist if each

  node is plugged into its own switch port. If an uplink port is included, one switch creates twenty-one single-node collision domains. A switch dynamically builds and maintains a Content-Addressable Memory (CAM) table, holding all of the

  necessary MAC information for each port. For a detailed description of how switches operate, and their key differences to hubs, see the reference link below.
