Cisco 200-125 Online Questions & Answers

• Question 141:

  Before installing a new, upgraded version of the IOS, what should be checked on the router, and which command should be used to gather this information? (Choose two.)

  A. the amount of available ROM
  B. the amount of available flash and RAM memory
  C. the version of the bootstrap software present on the router
  D. show version
  E. show processes
  F. show running-config
  B. the amount of available flash and RAM memory
  D. show version

  ---

  When upgrading a new version of the IOS we need to copy the IOS to the Flash so first we have to check if the Flash has enough memory or not. Also running the new IOS may require more RAM than the older one so we should check the available RAM too. We can check both with the "show version" command.

• Question 142:

  Under normal operations, cisco recommends that you configure switch ports on

  which vlan ?

  A. on the default vlan
  B. on the management vlan
  C. on the native vlan
  D. on any vlan except the default vlan
  D. on any vlan except the default vlan

• Question 143:

  What is the result of issuing the frame-relay map ip 192.168.1.2 202 broadcast command?

  A. defines the destination IP address that is used in all broadcast packets on DCLI 202
  B. defines the source IP address that is used in all broadcast packets on DCLI 202 C. defines the DLCI on which packets from the 192.168.1.2 IP address are received
  D. defines the DLCI that is used for all packets that are sent to the 192.168.1.2 IP address
  D. defines the DLCI that is used for all packets that are sent to the 192.168.1.2 IP address

  ---

  This command identifies the DLCI that should be used for all packets destined to the 192.168.1.2 address. In this case, DLCI 202 should be used.

• Question 144:

  Which command can you enter to view the ports that are assigned to VLAN 20?

  A. Switch#show vlan id 20
  B. Switch#show ip interface brief
  C. Switch#show interface vlan 20
  D. Switch#show ip interface vlan 20
  A. Switch#show vlan id 20

• Question 145:

  What are three advantages of VLANs? (Choose three.)

  A. VLANs establish broadcast domains in switched networks.
  B. VLANs utilize packet filtering to enhance network security.
  C. VLANs provide a method of conserving IP addresses in large networks.
  D. VLANs provide a low-latency internetworking alternative to routed networks.
  E. VLANs allow access to network services based on department, not physical location.
  F. VLANs can greatly simplify adding, moving, or changing hosts on the network.
  A. VLANs establish broadcast domains in switched networks.
  E. VLANs allow access to network services based on department, not physical location.
  F. VLANs can greatly simplify adding, moving, or changing hosts on the network.

  VLAN technology is often used in practice, because it can better control layer2 broadcast to improve network security. This makes network more flexible and scalable. Packet filtering is a function of firewall instead of VLAN.

• Question 146:

  Which two statements about GRE tunnels are true? (Choose two.)

  A. They can operate in tunnel mode and transport mode
  B. They provide privacy, integrity, and authenticity
  C. They encapsulate the payload.
  D. They add 8 bytes to the IP header of each packet.
  E. They allow multicast traffic to traverse WAN circuits
  C. They encapsulate the payload.
  E. They allow multicast traffic to traverse WAN circuits

• Question 147:

  Which two descriptions of the default behavior of a router when you enter an invalid Cisco IOS CLI command are true?

  A. The router returns an error message.
  B. The router queries the default DNS server for the invalid command.
  C. The router prompts the user to enter an IP address.
  D. The router sends a broadcast message in an attempt to resolve the invalid command to an IP address.
  E. The router displays a system message prompting you to configure a DNS server.
  F. The router interprets the invalid command as a hostname
  A. The router returns an error message.
  F. The router interprets the invalid command as a hostname

• Question 148:

  Which two facts about configuring EIGRPv6 are true? (Choose two.)

  A. You must configure neighboring devices with the same ipv6 hello-interval eigrp value
  B. If you change the interface delay, the EIGRPv4 delay remains unchanged.
  C. The variance command for EIGRPv6 is independent of EIGRPv4.
  D. If you change the interface bandwidth, the EIGRPv4 metric is afected.
  E. The router ID must be an IPv6 address.
  C. The variance command for EIGRPv6 is independent of EIGRPv4.
  D. If you change the interface bandwidth, the EIGRPv4 metric is afected.

• Question 149:

  Refer to the exhibit.

  

  An administrator cannot connect from R1 to R2. To troubleshoot this problem, the administrator has entered the command shown in the exhibit. Based on the output shown, what could be the problem?

  A. The serial interface is configured for the wrong frame size.
  B. The serial interface does not have a cable attached.
  C. The serial interface has the wrong type of cable attached.
  D. The serialinterface has a full buffer.
  E. The serial interface is configured for half duplex.
  C. The serial interface has the wrong type of cable attached.

• Question 150:

  When troubleshooting client DNS issues, which two tasks must you perform? (Choose two.)

  A. Ping a public website IP address.
  B. Determine whether a DHCP address has been assigned.
  C. Determine whether the hardware address is correct.
  D. Ping the DNS server.
  E. Determine whether the name servers have been configured.
  D. Ping the DNS server.
  E. Determine whether the name servers have been configured.
