Cisco 300-115 Online Questions & Answers

• Question 991:

  Which errdisable recovery command option enables a device to recover from an incorrect SFT state?

  A. link-monitor-failure
  B. sfp-config-mismatch
  C. gbic-invalid
  D. port-mode-failure
  C. gbic-invalid

• Question 992:

  Which SDM feature enables maximize resources for ACL?

  A. access
  B. routing
  C. standard
  D. VLAN
  A. access

• Question 993:

  Refer to the exhibit.

  

  What is the result of the configuration?

  A. The EtherChannels would not form because the load-balancing method must match on the devices.
  B. The EtherChannels would form and function properly even though the load-balancing and EtherChannel modes do not match.
  C. The EtherChannels would form, but network loops would occur because the load-balancing methods do not match.
  D. The EtherChannels would form and both devices would use the dst-ip load-balancing method because Switch1 is configured with EtherChannel mode active.
  B. The EtherChannels would form and function properly even though the load-balancing and EtherChannel modes do not match.

  An etherchannel will form if one end is active and the other is passive. The table below sum- marizes the results for LACP channel establishment based on the configuration of each side of a link: LACP Channel Establishment S1 S2 Established? On On Yes Active/Passive Active Yes On/Active/Passive Not Configured No On Active No Passive/On Passive No Load balancing can only be configured globally. As a result, all channels (manually configured, PagP, or LACP) use the same load-balancing. This is true for the switch globally, although each switch involved in the etherchannel can have non matching parameters for load balancing.

• Question 994:

  Which command enables you to detemine whether Etherchannel guard is enable globally?

  A. show spanning-tree inconsistentports
  B. show spanning-tree active
  C. show spanning-tree detail
  D. show spanning-tree summary
  C. show spanning-tree detail

• Question 995:

  How does SPAN interact with STP?

  A. STP is disabled on a destination port when a SPAN monitor session is active.
  B. STP is disabled on trunk ports carrying the SPAN VLAN.
  C. A designated SPAN source port maintains its SI P learning status.
  D. Designated SPAN source ports direct traffic to the root bridge of STP.
  B. STP is disabled on trunk ports carrying the SPAN VLAN.

• Question 996:

  A question about DHCP snooping feature. (Choose two.)

  A. limit / intercept messages from untrusted
  B. limit traffic from untrusted
  C. correlate IP to domain name
  D. drops all traffic outside the domain
  E. resource not available in 12.2 IOS
  A. limit / intercept messages from untrusted
  B. limit traffic from untrusted

• Question 997:

  Which SDM template disables routing and supports the maximum number of unicast MAC addresses?

  A. VLAN
  B. access
  C. default
  D. routing
  A. VLAN

  ---

  To allocate ternary content addressable memory (TCAM) resources for different usages, the switch SDM templates prioritize system resources to optimize support for certain features. You can select SDM templates to optimize these features:

  Access--The access template maximizes system resources for access control lists (ACLs) to accommodate a large number of ACLs. Default--The default template gives balance to all functions. Routing--The routing template maximizes

  system resources for IPv4 unicast routing, typically required for a router or aggregator in the center of a network.

  VLANs--The VLAN template disables routing and supports the maximum number of unicast MAC addresses. It would typically be selected for a Layer 2 switch.

• Question 998:

  A network engineer configured an Ethernet switch using these commands. Switch1(config) # spanning-tree portfast bpdufilter default Which statement about the spanning-tree portfast feature on the switch is true?

  A. If an interface is enabled for portfast receives BDPU, the port goes through the spanning-tree listening, learning, and forwarding states
  B. If an interface is enabled for portfast receives BDPU, the port does not go through the spanning-tree listening, learning, and forwarding states.
  C. If an interface is enabled for portfast receives BDPU, the port is shut down immediately
  D. If an interface is enabled for portfast receives BDPU, the port goes into the spanning-tree inconsistent state
  A. If an interface is enabled for portfast receives BDPU, the port goes through the spanning-tree listening, learning, and forwarding states

• Question 999:

  Which command configures all access ports on a switch to immediately enter the forwarding state when the switch is reset?

  A. spanning-tree portfast bpduguard default
  B. spanning-tree portfast default
  C. spanning-tree portfast
  D. spanning-tree portfast bpdufilter default
  B. spanning-tree portfast default

• Question 1000:

  Which two options are two results of using the command spanning-tree vlan 50 root primary within a spanning-tree network under global configuration? (Choose two.)

  A. Spanning tree determines the priority of the current root for VLAN 50 and reduces the priority of the local switch to a lower value.
  B. The priority value for VLAN 50 is set to 4094 on the root while the local switch priority is set to 32768.
  C. The spanning-tree timers are reduced to improve the convergence time for VLAN 50.
  D. All ports that are configured on the current switch with VLAN 50 transition to designated ports.
  E. The switchport that is configured for VLAN 50 is the primary connection to the spanning-tree root switch.
  A. Spanning tree determines the priority of the current root for VLAN 50 and reduces the priority of the local switch to a lower value.
  D. All ports that are configured on the current switch with VLAN 50 transition to designated ports.
