Cisco 200-105 Online Questions & Answers

• Question 441:

  When troubleshooting an issue with an SVI, which three areas do you check? (Choose three.)

  A. frame size
  B. routing
  C. interfaces
  D. ASIC
  E. gateway
  F. encapsulation
  B. routing
  C. interfaces
  E. gateway

• Question 442:

  Which statement is true, as relates to classful or classless routing?

  A. Classful routing protocols send the subnet mask in routing updates.
  B. RIPv1 and OSPF are classless routing protocols.
  C. Automatic summarization at classful boundaries can cause problems on discontiguous subnets.
  D. EIGRP and OSPF are classful routing protocols and summarize routes by default.
  C. Automatic summarization at classful boundaries can cause problems on discontiguous subnets.

  ---

  RIPv1, RIPv2, IGRP, and EIGRP all auto-summarize classful boundaries by default (OSPF does not). To make discontinuous networks work, meaning you don't want classful boundries to summarize, you need to turn off auto-summary.

• Question 444:

  Instructions

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

  THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION.

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

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

  This task has four multiple-choice questions. Be sure to answer all four questions before clicking the Next button.

  Scenario

  You are implementing PPP over serial links between R1 router and branch offices. In Phase 1 you must implement and verify PPP and GRE tunnel configurations as mentioned in the topology. In Phase 2 your colleague is expected to do

  NAT and ISP configurations between R1 and ISP router.

  Identify the issues that you encounter during PPP over serial links implementation.

  Routers Branch1, Branch2, and Branch3 connect to Router R1 in the main office over serial links.

  PPP multilink implementation is recommended between R1 and Branch1 routers.

  The GRE tunnel is configured between R2 and Branch2 routers, and traffic between Server farm1 10.10.10.0/24 network and Branch2 LAN 10.10.20.0/24 network, is routed over GRE tunnel using static route.

  You have console access on R1, R2, Branch1, Branch2, and Branch3 devices. Use only show commands to troubleshoot the issues.

  

  Why has the Branch3 router lost connectivity with R1?

  Use only show commands to troubleshoot because usage of the debug command is restricted on the Branch3 and R1 routers.

  A. A PPP chap hostname mismatch is noticed between Branch3 and R1.
  B. A PPP chap password mismatch is noticed between Branch3 and R1.
  C. PPP encapsulation is not configured on Branch3.
  D. The PPP chap hostname and PPP chap password commands are missing on the Branch3 router.
  A. A PPP chap hostname mismatch is noticed between Branch3 and R1.

  ---

  First we should check Branch3 (and R1) with the "show ip interface brief" command to find any Layer1/Layer 2 issue.

  

  We see the interfaces connecting between them are in "up/down" states which indicates a Layer 2 issue so we should check the configuration of these interfaces carefully with the "show running-config" command and pay attention to these interfaces.

  

  and on Branch3:

  

  We learn from above config is R1 is using CHAP to authenticate Branch3 router (via the "ppp authentication chap" command on R1). Branch3 router is sending CHAP hostname "Branch_3" and CHAP password "Branch3_Secret!" to R1 to be authenticated. Therefore, we should check if R1 has already been configured with such username and password or not with the "show running-config" command on R1:

  

  On R1 we see the configured username is "Branch3", not "Branch_3" so the usernames here are mismatched and this is the problem -> Answer A is correct.

• Question 445:

  Which statement about IPv6 is true?

  A. Addresses are not hierarchical and are assigned at random.
  B. Only one IPv6 address can exist on a given interface.
  C. There are 2.7 billion addresses available.
  D. Broadcasts have been eliminated and replaced with multicasts.
  D. Broadcasts have been eliminated and replaced with multicasts.

• Question 446:

  Refer to the exhibit.

  

  Router edge-1 is unable to establish OSPF neighbor adjacency with router ISP-1. Which two configuration changes can you make on edge-1 to allow the two routers to establish adjacency? (Choose two.)

  A. Set the subnet mask on edge-1 to 255.255.255.252.
  B. Reduce the MTU on edge-1 to 1514.
  C. Set the OSPF cost on edge-1 to 1522.
  D. Reduce the MTU on edge-1 to 1500.
  E. Configure the ip ospf mtu-ignore command on the edge-1 Gi0/0 interface.
  D. Reduce the MTU on edge-1 to 1500.
  E. Configure the ip ospf mtu-ignore command on the edge-1 Gi0/0 interface.

  ---

  A situation can occur where the interface MTU is at a high value, for example 9000, while the real value of the size of packets that can be forwarded over this interface is 1500. If there is a mismatch on MTU on both sides of the link where OSPF runs, then the OSPF adjacency will not form because the MTU value is carried in the Database Description (DBD) packets and checked on the other side.

• Question 447:

  In an HSRP failover environment, which two tasks must you perform on the preferred active router so that it always assumes the active role when it comes up? (Choose two.)

  A. Configure the router with a higher priority than the other routers in the group
  B. Configure the router with a higher MAC address than the other routers in the group
  C. Configure preemption on the router
  D. Configure the router with a higher IP address than the other routers in the group
  E. Configure tracking on the router
  A. Configure the router with a higher priority than the other routers in the group
  C. Configure preemption on the router

• Question 448:

  

  Refer to the output above. Applying this configuration will result in which outcome?

  A. Command starting with aaa are rejected because the aaa new-model command is missing
  B. The user is authenticated against the configured RADIUS server
  C. The user is authenticated against the local database
  D. When the enable secret password is entered the user will gain access to the device
  A. Command starting with aaa are rejected because the aaa new-model command is missing

• Question 449:

  Instructions:

  Enter IOS commands on the Dubai router to verify network operation and answer for multiple-choice questions. THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION.

  Click on the Console PC to gain access to the console of the router. No console or enable passwords are required.

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

  

  

  What would be the destination Layer 2 address in the frame header for a frame that is being forwarded by Dubai to the host address of 172.30.4.4?

  A. 825
  B. 230
  C. 694
  D. 387
  C. 694

  ---

  According to command output 172.30.4.4 is using the 694 dlci value.

• Question 450:

  Which command do you enter to permit IPv6 functionality on an EIGRPv3 interface?

  A. Router1(config)#ipv6 unicast-routing
  B. Router1(config-if)#ipv6 router eigrp 1
  C. Router1(config-if)#ipv6 enable
