Cisco 300-115 Online Questions & Answers

• Question 601:

  A question about VRRP. There were 4 different switches with different priorities and two of them they had the same IP address configured.

  (From candidate: I think that they were using the physical interfaces. I was confused since I though that when two of them are using the same IP address would be a conflict and other device would be used)

  A. Router A which had 192.168.0.1 and priority 120
  B. www.certbus.com
  C. www.certbus.com
  D. www.certbus.com
  A. Router A which had 192.168.0.1 and priority 120

• Question 602:

  A network engineer notices inconsistent Cisco Discovery Protocol neighbors according to the diagram that is provided. The engineer notices only a single neighbor that uses Cisco Discovery Protocol, but it has several routing neighbor relationships. What would cause the output to show only the single neighbor?

  A. The routers are connected via a Layer 2 switch.
  B. IP routing is disabled on neighboring devices.
  C. Cisco Express Forwarding is enabled locally.
  D. Cisco Discovery Protocol advertisements are inconsistent between the local and remote devices.
  A. The routers are connected via a Layer 2 switch.

  ---

  If all of the routers are connected to each other using a layer 2 switch, then each router will only have the single switch port that it connects to as its neighbor. Even though multiple routing neighbors can be formed over a layer 2 network, only the physical port that it connects to will be seen as a CDP neighbor. CDP can be used to determine the physical topology, but not necessarily the logical topology.

  A. no spanning-tree vlan 10

• Question 605:

  Which errdisable recovery command option enables a device to recover from an EtherChannel error?

  A. channel-misconfig
  B. security-violation
  C. sfp-config-nusmatch

  C. sfp-config-nusmatch

• Question 606:

  Which two statements about PortFast are true? (Choose two.)

  A. It forces the port to skip all spanning-tree states.
  B. The port is error-disabled if it attempts to move into the listening or learning states.
  C. It allows the port to skip the learning state only
  D. The port moves immediately to the forwarding state when a device is connected.
  E. It is most appropriate for ports that provide connectivity to individual workstations or servers
  D. The port moves immediately to the forwarding state when a device is connected.
  E. It is most appropriate for ports that provide connectivity to individual workstations or servers

• Question 607:

  A workstation technician moves a PC from one office desk to another. Before the move the PC has network connectivity After the move as the PC plugged into the now network port, it loses network connectivity and the network switch port

  becomes err disabled.

  Which option can cause the Issue?

  A. wrong VLAN
  B. wrong switch port mode
  C. port security
  D. speed issue
  C. port security

• Question 608:

  Which two reasons to deploy UDLD on a switch are true? (Choose two.)

  A. It can interact with Layer 1 mechanisms to monitor the status of physical links.
  B. It can replace Cisco Discovery Protocol.
  C. It can replace spanning tree.
  D. It can prevent forwarding loops that result unidirectional links.
  E. It can interact with Layer 2 mechanisms to monitor the status of physical links.
  A. It can interact with Layer 1 mechanisms to monitor the status of physical links.
  D. It can prevent forwarding loops that result unidirectional links.

• Question 609:

  Which statement is true when UDLD is configured on a link and the link is determined to be unidirectional?

  A. The port remains up for a configured time interval and then error disables if the link remains undirccironal.
  B. LLDP is enabled on the port.
  C. The port sends a log message to the console.
  D. The port is disabled immediately
  A. The port remains up for a configured time interval and then error disables if the link remains undirccironal.
