After reviewing UDLD status on switch ports, an engineer notices that the current bidirectional state for an access port is "Unknown".
Which statement describes what this indicates about the status of the port?
- A . The bidirectional status of "unknown" indicates that the port will go into the disabled state because it stopped receiving UDLD packets from its neighbor.
- B . UDLD moved into aggressive mode after inconsistent acknowledgements were detected.
- C . The port is fully operational and no known issues are detected.
- D . The UDLD port is placed in the "unknown" state for 5 seconds until the next UDLD packet is received on the interface.
Refer to the output below.
Which statements about the current configuration on port Gigabit Ethernet2/0/1 is true?
- A . It is an access port in VLAN 700
- B . It is an access port configured for a phone and a PC
- C . It is a trunk port and the native VLAN is VLAN 700
- D . It is a trunk port and the native VLAN is VL AN 1
Refer to the exhibit.
Which statement describes the result if a switch that is running PVST+ is added to this network?
- A . Both switches operate in the PVST+ mode
- B . Spanning tree is disabled automatically on the network
- C . Both switches operate in the Rapid PVST+ mode
- D . Spanning tree continues to operate in Rapid PVST+ on DSW2 and the new switch operates in PVST+
Which two tasks must you perform on a device to ensure that an Ether Channel operates at Layer3? (Choose two)
- A . Configure Ether Channel directly on the interface
- B . Configure the switchport mode access command on the device
- C . Configure the no switchport command on the physical interface (s)
- D . Configure the channel-group 10 mode on command on the port channel
- E . Configure the switchport mode trunk command on the device
Which two statements about default FHRP behavior are true? (Choose two.)
- A . A standby HSRP router becomes active if it has a higher priority than the priority of the current active router
- B . A VRRP backup virtual router becomes the master router if its priority is higher than the priority of the current master router.
- C . Unless specifically Configured, the priority of an HSRP router is 200.
- D . A backup GLBP active virtual gateway can become active only if the current active virtual gateway fails.
- E . Preemption is enabled by default.
Which two 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 interact with Layer 2 mechanisms to monitor the status of physical links
- C . It can replace Cisco Discovery Protocol
- D . It can replace spanning tree
- E . It can prevent forwarding loops that result from unidirectional links
Refer to the exhibit.
Which two statements can be derived from the output of the show standby command? (Choose two)
- A . If Fa0/0 is shut down, the HSRP priority on R2 becomes 80
- B . R2 is using the default HSRP hello and hold timers
- C . R2 Fa1/0 regains mastership when the link comes back up
- D . Router with IP 10.10.1.3 is active because it has a higher IP address
- E . R2 becomes the active router after the hold time expires
Which option is a benefits of configuring UDLD on a link between two switches?
- A . UDLD remove switching loops
- B . UDLD determines the best switching path
- C . UDLD helps prevent switching loops
- D . UDLD provides a backup mechanism for fiber
