Q11. Which statement describes what happens when a switch enters dual active recovery mode?

A. The switch shuts down and waits for the VSL link to be restored before sending traffic.

B. All interfaces are shut down in the formerly active virtual switch member, but the new active virtual switch forwards traffic on all links.

C. The switch continues to forward traffic out all links and enables spanning tree on VSL link and all other links to prevent loops.

D. The VSS detects which system was last in active state and shuts down the other switch.

Answer: B


Q12. Which command does a network engineer use to verify the spanning-tree status for VLAN 10?

Q13. The command storm-control broadcast level 75 65 is configured under the switch port connected to the corporate mail server. In which three ways does this command impact the traffic? (Choose three.)

A. SNMP traps are sent by default when broadcast traffic reaches 65% of the lower-level threshold.

B. The switchport is disabled when unicast traffic reaches 75% of the total interface bandwidth.

C. The switch resumes forwarding broadcasts when they are below 65% of bandwidth.

D. Only broadcast traffic is limited by this particular storm control configuration.

E. Multicast traffic is dropped at 65% and broadcast traffic is dropped at 75% of the total interface bandwidth.

F. The switch drops broadcasts when they reach 75% of bandwidth.

Answer: CDF

B. The SDM VLAN template causes the MAC address-table to overflow.

C. The VLAN template disables routing in hardware.

D. The switch needs to be rebooted before the SDM template takes effect.
