Cisco 200-105 Online Questions & Answers

• Question 421:

  When a user attempts to authenticate with TACACS+.

  Which three responses from the TACACS+ daemon are possible? (Choose three.)

  A. PERSIST
  B. FAULT
  C. CONTINUE
  D. ERROR
  E. ACCEPT
  F. REPEAT
  C. CONTINUE
  D. ERROR
  E. ACCEPT

  ---

  The network access server will eventually receive one of the following responses from the TACACS+ daemon:

  a.

  ACCEPT--The user is authenticated and service may begin. If the network access server is configured to requite authorization, authorization will begin at this time. b. REJECT--The user has failed to authenticate. The user may be denied further access, or will be prompted to retry the login sequence depending on the TACACS+ daemon. c. ERROR--An error occurred at some time during authentication. This can be either at the daemon or in the network connection between the daemon and the network access server. If an ERROR response is received, the network access server will typically try to use an alternative method for authenticating the user.

  d.

  CONTINUE--The user is prompted for additional authentication information.

  A. Network 172.16.1.32 mask 255.255.255.224

• Question 424:

  Which two statements about access ports are true? (Choose two.)

  A. VLANs must be in the VLAN database before they can be assigned to an access port
  B. They are configured with 802.1Q encapsulation
  C. A device must have at least one access port configured for each trunk port
  D. They are assigned to VLAN 1 by default
  E. They record all MAC addresses they receive
  A. VLANs must be in the VLAN database before they can be assigned to an access port
  D. They are assigned to VLAN 1 by default

• Question 425:

  Scenario

  Refer to the topology. Your company has connected the routers R1, R2, and R3 with serial links. R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also connected to the routers R4 and R5.

  The EIGRP routing protocol is configured.

  You are required to troubleshoot and resolve the EIGRP issues between the various routers. Use the appropriate show commands to troubleshoot the issues.

  Instructions

  Enter the IOS commands on the device to verify the network operations and to find the answers for the multiple-choice questions.

  THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION.

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

  To access the multiple-choice questions, click 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.

  

  

  

  

  The loopback interfaces on R4 with the IP addresses of 10.4.4.4/32, 10.4.4.5/32, and 10.4.4.6/32 are not appearing in the routing table of R5.

  Why are the interfaces missing?

  A. The interfaces are shutdown, so they are not being advertised.
  B. R4 has been incorrectly configured to be in another AS, so it does not peer with R5.
  C. Automatic summarization is enabled, so only the 10.0.0.0 network is displayed.
  D. The loopback addresses haven't been advertised, and the network command is missing on R4.
  B. R4 has been incorrectly configured to be in another AS, so it does not peer with R5.

  ---

  For an EIGRP neighbor to form, the following must match: Neighbors must be in the same subnet K values AS numbers Authentication method and key strings Here, we see that R4 is configured for EIGRP AS 2, when it should be AS 1.

  

• Question 426:

  What is one benefit of PVST+?

  A. PVST+ supports Layer 3 load balancing without loops.
  B. PVST+ reduces the CPU cycles for all the switches in the network.
  C. PVST+ allows the root switch location to be optimized per VLAN.
  D. PVST+ automatically selects the root bridge location, to provide optimized bandwidth usage.
  C. PVST+ allows the root switch location to be optimized per VLAN.

  Per VLAN Spanning Tree (PVST)

  Introduction

  Per VLAN Spanning Tree (PVST) maintains a spanning tree instance for each VLAN configured in the network. It means a switch can be the root bridge of a VLAN while another switch can be the root bridge of other VLANs in a common

  topology. For example, Switch 1 can be the root bridge for Voice data while Switch 2 can be the root bridge for Video data. If designed correctly, it can optimize the network traffic.

• Question 427:

  Which statement about STP root bridges is true?

  A. Each VLAN must have a separate root bridge.
  B. An individual switch can be the root bridge for only one VLAN.
  C. The switch with the highest root ID is elected as the root bridge.
  D. Dynamic root bridge assignment is most efficient.
  A. Each VLAN must have a separate root bridge.

• Question 428:

  Refer to the exhibit. From R1, a network administrator is able to ping the serial interface of R2 but, unable to ping any of the subnets attached to RouterB. Based on the partial outputs in the exhibit, what could be the problem?

  

  

  A. EIGRP does not support VLSM.
  B. The EIGRP network statements are incorrectly configured.
  C. The IP addressing on the serial interface of RouterA is incorrect.
  D. The routing protocol has summarized on the classful boundary.
  E. EIGRP has been configured with an invalid autonomous system number.
  D. The routing protocol has summarized on the classful boundary.

  If you look carefully at the R2 ip route, you will discover that the R2 does not learn any network from R1; this is because the routing protocol used here (EIGRP) performs auto summary when advertising routes to peers across a network. So in this case the address 172.17.0.0/26 is a summarized address. If the router was configured with no auto summary command, R2 LAN addresses would have been advertised and reached.

• Question 430:

  A. exstart state > loading state > exchange state > full state
  B. exstart state > exchange state > loading state >full state
  C. exstart state > full state > loading state > exchange state
  D. loading state > exchange state > full state > exstart state
