Cisco 300-115 Online Questions & Answers

• Question 561:

  Refer to the exhibit.

  

  Which option shows the expected result if a show vlan command is issued?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

  ---

  In this case, the port has been configured both as a trunk and as a switchport in data vlan 10. Obviously, a port can not be both, so even though Cisco IOS will accept both, the port will actually be used as a trunk, ignoring the switchport access VLAN 10 command.

• Question 562:

  For client server failover purposes, the application server team has indicated that they must not have the standard 30 second delay before their switchport enters a forwarding state. For their disaster recovery feature to operate successfully, they require the switchport to enter a forwarding state immediately. Which spanning- tree feature satisfies this requirement?

  A. Rapid Spanning-Tree
  B. Spanning-Tree Timers
  C. Spanning-Tree FastPort
  D. Spanning-Tree PortFast
  E. Spanning-Tree Fast Forward
  D. Spanning-Tree PortFast

  In order to allow immediate transition of the port into forwarding state, enable the STP PortFast feature.

  PortFast immediately transitions the port into STP

  forwarding mode upon linkup. The port still participates in STP. So if the port is to be a part of the loop, the port eventually transitions into STP blocking mode.

  Example configuration:

  Switch-C# configure terminal

  Switch-C(config)# interface range fa0/3 - 24 Switch-C(config-if-range)# spanning-tree portfast Reference:

  B. Maximum 4 AVFs allowed in a group
  E. GLBP supports up to 1024 virtual routers per group.

• Question 564:

  Which statement about Cisco StackWise is true?

  A. When a new switch is added, the master switch suspends traffic forwarding until the new switch is updated with the least running configuration.
  B. The stack elects a master switch and a standby switch to support rapid failover.
  C. The entire stack communicates using a single management IP address.
  D. If a single interconnect cable in the stack fails, the stack can continue to operate at full bandwidth
  C. The entire stack communicates using a single management IP address.

• Question 565:

  Which two TLVs are mandatory in LLDP advertisements? (Choose two.)

  A. Platform TLV
  B. System Capability TLV
  C. Network Policy TLV
  D. System Name TLV
  E. Native VLAN TLV
  B. System Capability TLV
  D. System Name TLV

• Question 566:

  A. It sets last resort failback authentication method.
  B. It override the enable authentication method.
  C. It override the radius authentication method.
  D. It override the tacacs+ authentication method.
  A. It sets last resort failback authentication method.

• Question 567:

  Question about what would be, if write command "spanning-tree portfast trunk"?

  A. trunk port will be immediately
  B. trunk port can be portfast mode
  C. BDPU turn this port to err-disabled
  B. trunk port can be portfast mode

• Question 568:

  Which statement about the use of PAgP link aggregation on a Cisco switch that is running Cisco IOS Software is true?

  A. PAgP modes are off, auto, desirable, and on. Only the combinations auto-desirable, desirable- desirable, and on-on allow the formation of a channel.
  B. PAgP modes are active, desirable, and on. Only the combinations active-desirable, desirable- desirable, and on-on allow the formation of a channel.
  C. PAgP modes are active, desirable, and on. Only the combinations active-active, desirable- desirable, and on-on allow the formation of a channel.
  D. PAgP modes are off, active, desirable, and on. Only the combinations auto-auto, desirable- desirable, and on-on allow the formation of a channel.
  A. PAgP modes are off, auto, desirable, and on. Only the combinations auto-desirable, desirable- desirable, and on-on allow the formation of a channel.

  ---

  PAgP modes are off, auto, desirable, and on. Only the combinations auto-desirable, desirable- desirable, and on-on will allow a channel to be formed.

  The PAgP modes are explained below.

  1.on: PAgP will not run. The channel is forced to come up. 2.off: PAgP will not run. The channel is forced to remain down. 3.auto: PAgP is running passively. The formation of a channel is desired; however, it is not initiated. 4.desirable: PAgP

  is running actively. The formation of a channel is desired and ini- tiated. Only the combinations of auto-desirable, desirable-desirable, and on-on will allow a channel to be formed. If a device on one side of the channel does not support PAgP,

  such as a router, the device on the other side must have PAgP set to on.
