Cisco 200-125 Online Questions & Answers

• Question 331:

  Several users on your network have complained of connectivity issues to a specific host. While troubleshooting task can you perform to eliminate DNS issues as the cause?

  A. Connect to the host by its IP address
  B. Verity the DHCP settings on the host
  C. Verity that a valid route to the host is present in the routing table
  D. Connect to the host by its FQDN
  D. Connect to the host by its FQDN

• Question 332:

  In an Ethernet network, under what two scenarios can devices transmit? (Choose two.)

  A. when they receive a special token
  B. when there is a carrier
  C. when they detect no other devices are sending
  D. when the medium is idle
  E. when the server grants access
  C. when they detect no other devices are sending
  D. when the medium is idle

  ---

  Ethernet network is a shared environment so all devices have the right to access to the medium. If more than one device transmits simultaneously, the signals collide and cannot reach the destination.

  If a device detects another device is sending, it will wait for a specified amount of time before attempting to transmit.

  When there is no traffic detected, a device will transmit its message. While this transmission is occurring, the device continues to listen for traffic or collisions on the LAN. After the message is sent, the device returns to its default listening

  mode.

• Question 335:

  When an interface is configured with PortFast BPDU guard, how does the interface respond when it receives a BPDU?

  A. It continues operating normally.
  B. It goes into a down/down state.
  C. It becomes the root bridge for the configured VLAN.
  D. It goes into an errdisable state.
  D. It goes into an errdisable state.

• Question 336:

  Which statement about QoS default behavior is true?

  A. Ports are untrusted by default.
  B. VoIP traffic is passed without being tagged.
  C. Video traffic is passed with a well-known DSCP value of 46.
  D. Packets are classified internally with an environment.
  E. Packets that arrive with a tag are untagged at the edge of an administrative domain.
  E. Packets that arrive with a tag are untagged at the edge of an administrative domain.

  Explanation: Frames received from users in the administratively-defined VLANs are classified or tagged for transmission to other devices. Based on rules that you define, a unique identifier (the tag) is inserted in each frame header before it is forwarded. The tag is examined and understood by each device before any broadcasts or transmissions to other switches, routers, or end stations. When the frame reaches the last switch or router, the tag is removed before the frame is sent to the target end station. VLANs that are assigned on trunk or access ports without identification or a tag are called native or untagged frames. For IEEE 802.1Q frames with tag information, the priority value from the header frame is used. For native frames, the default priority of the input port is used. Each port on the switch has a single receive queue buffer (the ingress port) for incoming traffic. When an untagged frame arrives, it is assigned the value of the port as its port default priority. You assign this value by using the CLI or CMS. A tagged frame continues to use its assigned CoS value when it passes through the ingress port.
