• Question 5:

  DRAG DROP

  You are configuring a default route on a Cisco router. Drag and drop the commands from the left into the correct sequence on the right. Not all commands are used.

  Select and Place:

  

  

• Question 6:

  You work for a company that provides managed network services, and of your real estate clients running a small office is experiencing network issues, Troubleshoot the network issues.

  Router R1 connects the main office to internet, and routers R2 and R3 are internal routers NAT is enabled on Router R1.

  The routing protocol that is enable between routers R1, R2, and R3 is RIPv2.

  R1 sends default route into RIPv2 for internal routers to forward internet traffic to R1.

  Server1 and Server2 are placed in VLAN 100 and 200 respectively, and dare still running router on stick configuration with router R2.

  You have console access on R1, R2, R3, and L2SW1 devices.

  Use only show commands to troubleshoot the issues.

  Instructions

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

  This task does not require device configuration.

  Click the device icon 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.

  Examine R2 configuration, the traffic that is destined to R3 LAN network sourced from Router R2 is forwarded to R1 instead R3. What could be an issue?

  

  A. RIPv2 enabled on R3, but R3 LAN network that is not advertised into RIPv2 domain.
  B. RIPv2 routing updates are suppressed between R2 and R3 using passive interface feature.
  C. RIPv2 not enabled on R3.
  D. No issue that is identified; this behavior is normal since default route propagated into RIPv2 domain by Router R1.
  C. RIPv2 not enabled on R3.

• Question 7:

  

  Refer to the exhibit. If switch-A receives a frame with destination MAC address 0000.0000.0001 on its Fa0/1 interface, how does it process the frame?

  A. It holds the packet until MAC address timer expires and then drops the frame.
  B. It forwards the frame back out of interface Fa0/1.
  C. It floods the frame to all interfaces except Fa0/1.
  D. It drops the frame immediately.
  D. It drops the frame immediately.

• Question 8:

  In which two scenarios do you implement private IPv4 IP addresses? (Choose two.)

  A. on the webmail portal of an organization
  B. on the connection that a mobile device uses for application updates
  C. to connect network equipment between different IDFs
  D. for the VPN solution that end users use to connect to the local network
  E. on an application server that connects to a local database server
  C. to connect network equipment between different IDFs
  E. on an application server that connects to a local database server
