Which two commands ensure that DSW1 becomes root bridge for VLAN 10 and 20?

• A.spanning-tree mst 1 priority 1
• B.spanning-tree mst 1 root primary
• C.spanning-tree mstp vlan 10,20 root primary
• D.spanning-tree mst vlan 10,20 priority root
• E.spanning-tree mst 1 priority 4096

Correct Answer: B,E

Explanation

From the second command output (show spanning-tree mst) we learn that MST1 includes VLANs 10 &
20.Therefore if we want DSW1 to become root bridge for these VLANs we need to set the MST 1 region to root ->The command "spanning-tree mst 1 root primary" can do the trick. In fact, this command runs a macro and setsthe priority lower than the current root.
Also we can see the current root bridge for these VLANs has the priority of 32769 (default value + sysid) so wecan set the priority of DSW1 to a specific lower value. But notice that the priority must be a multiple of
4096.

Which QoS queuing method transmits packets out of the interface in the order the packets arrive?

• A.custom
• B.weighted- fair

First-in, first-out (FIFO): FIFO entails no concept of priority or classes of traffic. With FIFO, transmission of packets out the interface occurs in the order the packets arrive, which means no QoS.
