Cisco 200-105 Online Questions & Answers

• Question 71:

  What are two enhancements that OSPFv3 supports over OSPFv2? (Choose two.)

  A. It can support multiple IPv6 subnets on a single link.
  B. It requires the use of ARP.
  C. It routes over links rather than over networks.
  D. It supports up to 2 instances of OSPFv3 over a common link.
  A. It can support multiple IPv6 subnets on a single link.
  C. It routes over links rather than over networks.

  Here is a list of the differences between OSPFv2 and OSPFv3: They use different address families (OSPFv2 is for IPv4-only, OSPFv3 can be used for IPv6-only or both protocols OSPFv3 introduces new LSA types OSPFv3 has different packet format OSPFv3 uses different flooding scope bits (U/S2/S1) OSPFv3 adjacencies are formed over link-local IPv6 communications OSPFv3 runs per-link rather than per-subnet OSPFv3 supports multiple instances on a single link, Interfaces can have multiple IPv6 addresses OSPFv3 uses multicast addresses FF02::5 (all OSPF routers), FF02::6 (all OSPF DRs) OSPFv3 Neighbor Authentication done with IPsec (AH) OSPFv2 Router ID (RID) must be manually configured, still a 32-bit number

• Question 72:

  Which set of commands is recommended to prevent the use of a hub in the access layer?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  C. Option C

• Question 73:

  Which routing protocols are compatible with stubs. (Choose two)

  A. OSPF
  B. EIGRP
  C. EGP
  D. BGP
  E. IS_IS
  F. RIP
  A. OSPF
  B. EIGRP

• Question 74:

  Which encapsulation type is a Frame Relay encapsulation type that is supported by Cisco routers?

  A. IETF
  B. ANSI Annex D
  C. Q9333-A Annex A
  D. HDLC
  A. IETF

  ---

  Cisco supports two Frame Relay encapsulation types: the Cisco encapsulation and the IETF Frame Relay encapsulation, which is in conformance with RFC 1490 and RFC 2427. The former is often used to connect two Cisco routers while the

  latter is used to connect a Cisco router to a non-Cisco router. You can test with your Cisco router when typing the command

  Router(config-if)#encapsulation frame-relay? on a WAN link.

  Note: Three LMI options are supported by Cisco routers are ansi, Cisco, and Q933a. They represent the ANSI Annex D, Cisco, and ITU Q933-A (Annex A) LMI types, respectively.

  HDLC is a WAN protocol same as Frame-Relay and PPP so it is not a Frame Relay encapsulation type.

  

• Question 75:

  Which interface counter can you use to diagnose a duplex mismatch problem?

  A. runts
  B. CRC errors
  C. no carrier
  D. late collisions
  E. deferred
  F. giants
  B. CRC errors

• Question 76:

  What can cause two OSPF neighbors to be stuck in the EXSTART state?

  A. There is a low bandwidth connection between neighbors.
  B. The neighbors have different MTU settings.
  C. The OSPF interfaces are in a passive state.
  D. There is only layer one connectivity between neighbors.
  B. The neighbors have different MTU settings.

• Question 77:

  Which WAN solution is secured by default?

  A. VPN
  B. DSL
  C. LCP
  D. PPP
  A. VPN

• Question 78:

  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 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.

  

  

  

  Which path does traffic take from R1 to R5?

  A. The traffic goes through R2.
  B. The traffic goes through R3.
  C. The traffic is equally load-balanced over R2 and R3
  D. The traffic is unequally load-balanced over R2 and R3.
  A. The traffic goes through R2.

  ---

  Using the "show ip int brief command" on R5 we can see the IP addresses assigned to this router. Then, using the "show ip route" command on R1 we can see that to reach 10.5.5.5 and 10.5.5.55 the preferred path is via Serial 1/3, which we see from the diagram is the link to R2.

  C. 99
  D. 100
  E. 299
  F. 1099
  D. 100

• Question 80:
