Cisco 200-125 Online Questions & Answers

• Question 951:

  Refer to the exhibit.

  

  What is the meaning of the term dynamic as displayed in the output of the show frame- relay map command shown?

  A. The Serial0/0 interface is passing traffic.
  B. The DLCI 100 was dynamically allocated by the router.
  C. The Serial0/0 interface acquired the IP address of 172.16.3.1 from a DHCP server.
  D. The DLCI 100 will be dynamically changed as required to adapt to changes in the Frame Relay cloud.
  E. The mapping between DLCI 100 and the end station IP address 172.16.3.1 was learned through Inverse ARP.
  E. The mapping between DLCI 100 and the end station IP address 172.16.3.1 was learned through Inverse ARP.

  Inverse Address Resolution Protocol (Inverse ARP) was developed to provide a mechanism for dynamic DLCI to Layer 3 address maps. Inverse ARP works much the same way Address Resolution Protocol (ARP) works on a LAN. However, with ARP, the device knows the Layer 3 IP address and needs to know the remote data link MAC address. With Inverse ARP, the router knows the Layer 2 address which is the DLCI, but needs to know the remote Layer 3 IP address. When using dynamic address mapping, Inverse ARP requests a next-hop protocol address for each active PVC. Once the requesting router receives an Inverse ARP response, it updates its DLCI-to-Layer 3 address mapping table. Dynamic

  address mapping is enabled by default for all protocols enabled on a physical interface. If the Frame Relay environment supports LMI autosensing and Inverse ARP, dynamic address mapping takes place automatically. Therefore, no static address mapping is required.

• Question 952:

  when you troubleshoot an IPv4 connectivity issue on a router, which three router configuration checks you must perform?

  A. Verify that the router interface IP address IP address is correct.
  B. Verify that the DNS is configured correctly.
  C. Verify that the router and the host use the same subnet mask.
  D. Verify that the router firmware is up-to-date.
  E. Verify that a default route is configured.
  F. Verify that the route appears in the routing table
  A. Verify that the router interface IP address IP address is correct.
  C. Verify that the router and the host use the same subnet mask.
  F. Verify that the route appears in the routing table

• Question 953:

  Refer to the exhibit.

  

  The server on this network is configured with an MTU of 9216, and the two interfaces on router R1 are configured for MTUs of 2000 and 3000 as shown. What is the largest packet size that can pass between the workstation and the server?

  A. 1500 bytes
  B. 2000 bytes
  C. 3000 bytes
  D. 9216 bytes
  A. 1500 bytes

• Question 954:

  What happens to new traffic is sent to a destination MAC address after the MAC aging time expires?

  A. it is flooded
  B. it is dropped
  C. it is process-switched
  D. it is queued
  A. it is flooded

• Question 955:

  Which statement about NTP is true?

  A. The default authentication key number is 1.
  B. The default source address of an NTP message is the interface connected to the next-hop for the server peer address.
  C. The default stratum number is 5.
  D. Each device is enabled as a server by default and propagates NTP messages to all peers on its default LAN.
  B. The default source address of an NTP message is the interface connected to the next-hop for the server peer address.

• Question 956:

  Which three options are types of slow VLAN connectivity? (Choose three.)

  A. slow broadcast domain connectivity
  B. slow routing domain connectivity
  C. slow default gateway connectivity
  D. slow application domain connectivity
  E. slow collision domain connectivity
  F. slow inter-VLAN connectivity
  A. slow broadcast domain connectivity
  D. slow application domain connectivity
  E. slow collision domain connectivity

• Question 957:

  Drag the Cisco default administrative distance to the appropriate routing protocol or route. (Not all options are used.)

  Select and Place:

  

  

• Question 958:

  Which protocol can cause overload on a CPU of a managed device?

  A. Netflow
  B. WCCP
  C. IP SLA
  D. SNMP
  D. SNMP

  ---

  Sometimes, messages like this might appear in the router console:

  %SNMP-3-CPUHOG: Processing [chars] of [chars]

  They mean that the SNMP agent on the device has taken too much time to process a request.

  You can determine the cause of high CPU use in a router by using the output of the show process cpu command.

  Note: A managed device is a part of the network that requires some form of monitoring and management (routers, switches, servers, workstations, printers...).

• Question 959:

  Drag and drop the extended traceout option from the left onto the correct description on the right.

  Select and Place:

• Question 960:

  Refer to the exhibit.

  

  A junior network administrator was given the task of configuring port security on SwitchA to allow only PC_A to access the switched network through port fa0/1. If any other device is detected, the port is to drop frames from this device. The administrator configured the interface and tested it with successful pings from PC_A to RouterA, and then observes the output from these two show commands.

  Which two of these changes are necessary for SwitchA to meet the requirements? (Choose two.)

  A. Port security needs to be globally enabled.
  B. Port security needs to be enabled on the interface.
  C. Port security needs to be configured to shut down the interface in the event of a violation.
  D. Port security needs to be configured to allow only one learned MAC address.
  E. Port security interface counters need to be cleared before using the show command.
  F. The port security configuration needs to be saved to NVRAM before it can become active.
  B. Port security needs to be enabled on the interface.
  D. Port security needs to be configured to allow only one learned MAC address.

  ---

  From the output we can see that port security is disabled so this needs to be enabled. Also, the maximum number of devices is set to 2 so this needs to be just one if we want the single host to have access and nothing else.
