• Question 48:

  FILL BLANK

  Case study.

  

  Some notices from above configuration:

  +The OSPF network type berween R2andR3 is non broadcast.

  Q1: Show ip ospf database

  Q2: Show ip ospf interface serial 1/0

  Q3: Show ip ospf

  Q4: Show ip route

  You have been asked to evaluate an OSPF network and to answer questions a customer has about its operation. Note: You are not allowed to use the show running-config command.

  

  Although in this sim we are not allowed to use “show running-config” command but we post the configuration here so that you can understand more about the topology.

  How many times was SPF algorithm executed on R4 for Area 1?

  Correct Answer. 9
  9

  ---

  We can check the number of executed SPF algorithm via the “show ip ospf” command on R4:

  

  In the output above we can see SPF has been executed 9 times.

• Question 49:

  For troubleshooting purposes, which method can you use in combination with the "debug ip packet" command to limit the amount of output data?

  A. You can disable the IP route cache globally.
  B. You can use the KRON scheduler
  C. You can use an extended access list.
  D. You can use an IOS parser.
  E. You can use the RITE traffic exporter
  C. You can use an extended access list.

• Question 50:

  Drag and Drop

  Drag and drop the challenge Handshake Authentication Protocol steps from the left into the correct order in which they occur on the right.

  Select and Place:

  

  

  ---

  The Challenge Handshake Authentication Protocol (CHAP) verifies the identity of the peer by means of a three-way handshake. These are the general steps performed in CHAP:

  1. After the LCP (Link Control Protocol) phase is complete, and CHAP is negotiated between both devices,the authenticator sends a challenge message to the peer.

  2. The peer responds with a value calculated through a one-way hash function (Message Digest 5 (MD5)).

  3. The authenticator checks the response against its own calculation of the expected hash value. If the values match, the authentication is successful. Otherwise, the connection is terminated.
