  A. The serial connection to the NorthCoast branch office.
  B. The serial connection to the North branch office.
  C. The serial connection to the Southlands branch office.
  D. The serial connection to the Multinational Core.

  Cisco default encapsulation is HDLC which is by default enabled on all cisco router. If we want to enable other encapsulation protocol (PPP,X.25 etc) we need to define in interface setting. But here except s1/1 all interface defined by other encapsulation protocol so we will assume default encapsulation running on s1/1 interface and s1/1 interface connected with North.

• Question 53:

  Which command do you enter to allow a new VLAN across a trunk?

  A. Switch(config-if)# switchport trunk except vlan10
  B. Switch(config-if)# no switchport trunk remove vlan10
  C. Switch(config-if)# switchport trunk allowed vlan add10
  D. Switch(config-if)# switchport trunk allowed vlan10
  C. Switch(config-if)# switchport trunk allowed vlan add10

• Question 54:

  B. It provides a secure accounting facility on the device.
  C. device-administration packets are encrypted in their entirely.
  D. It allows the user to remotely access devices from other vendors.
  E. It allows the users to be authenticated against a remote server.
  F. It supports access-level authorization for commands.
  C. device-administration packets are encrypted in their entirely.
  E. It allows the users to be authenticated against a remote server.
  F. It supports access-level authorization for commands.

• Question 56:

  Scenario

  Refer to the topology. Your company has decided to connect the main office with three other remote branch offices using point-to-point serial links. You are required to troubleshoot and resolve OSPF neighbor adjacency issues between the

  main office and the routers located in the remote branch offices.

  Use appropriate show commands to troubleshoot the issues and answer all four questions.

  Instructions

  Enter Cisco IOS commands on the device to verify network operation and answer the multiple-choice questions.

  THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION.

  Click on the device to gain access to the console of the device. No console or enable passwords are required.

  To access the multiple-choice questions, click on the numbered boxes on the left of the top panel.

  There are four multiple-choice questions with this task. Be sure to answer all four questions before clicking the Next button.

  

  

  

  

  R1 does not form an OSPF neighbor adjacency with R2. Which option would fix the issue?

  A. R1 ethernet0/1 is shutdown. Configure the no shutdown command.
  B. R1 ethernet0/l configured with a non-default OSPF hello interval of 25; configure no ip ospf hello-interval 25.
  C. R2 ethernet0/1 and R3 ethernet0/0 are configured with a non-default OSPF hello interval of 25; configure no ip ospf hello-interval 25.
  D. Enable OSPF for R1 ethernet0/l; configure ip ospf 1 area 0 command under ethernet0/1.
  B. R1 ethernet0/l configured with a non-default OSPF hello interval of 25; configure no ip ospf hello-interval 25.

  ---

  Looking at the configuration of R1, we see that R1 is configured with a hello interval of 25 on interface Ethernet 0/1 while R2 is left with the default of 10 (not configured).

  

• Question 57:

  Which router command can be used to verify the type of cable connected to interface serial 0/0?

  A. show running-config
  B. show controllers' serial 0/0
  C. show interfaces serial 0/0
  D. show ip interface serial 0/0
  B. show controllers' serial 0/0

• Question 58:

  Which two statements about using the CHAP authentication mechanism in a PPP link are true? (Choose two.)

  A. CHAP uses a two-way handshake.
  B. CHAP uses a three-way handshake.
  C. CHAP authentication periodically occurs after link establishment.
  D. CHAP authentication passwords are sent in plaintext.
  E. CHAP authentication is performed only upon link establishment.
  F. CHAP has no protection from playback attacks.
  B. CHAP uses a three-way handshake.
  C. CHAP authentication periodically occurs after link establishment.

  ---

  Understanding and Configuring PPP CHAP Authentication One-Way and Two-Way AuthenticationCHAP is defined as a one-way authentication method. However, you use CHAP in both directions to create a two-way authentication. Hence, with two-wayCHAP, a separate three-way handshake is initiated by each side. In the Cisco CHAP implementation, by default, the called party must authenticate the calling party (unless authentication is completely turned off). Therefore, a one-way authentication initiated by the called party is the minimum possible authentication. However, the calling party can also verify the identity of the called party, and this results in a two-way authentication. One-way authentication is often required when you connect to non-Cisco devices.

• Question 59:

  Refer to the exhibit. To what does the 128 refer in the router output O 168.12.240/30 [110/128] via 192.168.12.233,00:35:36, Serial 0?

  

  A. OSPF cost
  B. OSPF priority
  C. OSPF hop count
  D. OSPF ID number
  E. OSPF administrative distance
  A. OSPF cost

• Question 60:

  What is the result of issuing the frame-relay map ip 192.168.1.2 202 broadcast command?

  A. defines the destination IP address that is used in all broadcast packets on DCLI 202
  B. defines the source IP address that is used in all broadcast packets on DCLI 202
  C. defines the DLCI on which packets from the 192.168.1.2 IP address are received
  D. defines the DLCI that is used for all packets that are sent to the 192.168.1.2 IP address
  D. defines the DLCI that is used for all packets that are sent to the 192.168.1.2 IP address

  ---

  Frame-relay map ip 192.168.1.2 202 command statically defines a mapping between a network layer address and a DLCI. The broadcast option allows multicast and broadcast packets to flow across the link. The command frame-relay map ip

  192.168.1.2 202 broadcast means to mapping the distal IP 192.168.1.2 202 to the local DLCI. When the "broadcast" keyword is included, it turns Frame Relay network as a broadcast network, which can forward broadcasts.
