A. The two workstations continue to communication without a default gateway configured.

B. the command is unsupported on a trunk where VLANs have already been pruned manually.

C. The running configuration displays switch port trunk allowed vlan 1-5 for Fa0/2.

Refer to the exhibit.

Which two statements about the network environment of the device that generated this output are true? (Choose two.)

A. The local device has a higher priority setting than the active router.

B. The virtual IP address of the HSRP group is 10.1.1.1

C. If a router with a higher IP address and same HSRP priority as the active router becomes available, that router becomes the new active router 5 seconds later.

D. if the local device fails to receive a hello from the active router for more than 5 seconds, it can become the active router.

E. The hello and hold timers are set to custom values.

Question No: 12

Question No: 13

Refer to the exhibit.

BPDUGuard is enabled on both ports of SwitchA. Initially, LinkA is connected and forwarding traffic. A new LinkB is then attached between SwitchA and HubA. Which two statements about the possible result of attaching the second link are true? (Choose two.)

A. The switch port attached to LinkB does not transition to up.

B. One or both of the two switch ports attached to the hub goes into the err-disabled state when a BPDU is received.

C. Both switch ports attached to the hub transitions to the blocking state.

D. A heavy traffic load could cause BPDU transmissions to be blocked and leave a switching loop.

E. The switch port attached to LinkA immediately transitions to the blocking state.

Question No: 14
