#1. Which of the following can reduce the size of a broadcast domain? (Choose two.)

Select all that apply:

Prune VLANs

Use 802.1Q trunks

Use routed instead of switched interfaces

Tag the native VLAN

#2. You have three switches connected to VLAN 50. They're all running Spanning Tree and have the base MAC addresses: SW1 0010.84b0.ee30, SW2 007c.5d8a.e100, SW3 0084.8ede.fdd0 Which of the following will be the root for VLAN 50?

SW1

SW2

SW3

None of these

#3. You have three switches connected to VLAN 10. They have the following base MAC addresses and are set to the default priority: SW1 0010.84b0.ee30, SW2 007c.5d8a.e100, SW3 0084.8ede.fdd0. You plan to add another switch, SW4, to the topology but don't want it to become root. SW4 has a base MAC address of 000c.0f43.01a3. How can you accomplish this?

Set SW4's bridge priority to 0

Set SW4's bridge priority to 32768

Set SW4's bridge priority to 61440

Connect SW4 without making any other changes

#4. When you enable Spanning Tree on a switch, what does it advertise as the root bridge?

The 0000.0000.0000 address

The highest root bridge ID it receives

The first root ID it receives

Its own bridge ID

#5. How does a switch calculate the lowest cost to the root bridge?

Adding its own bridge priority to the bridge priority it receives in a BPDU

Adding its own interface cost to the cost it receives in a BPDU

Adding its own port priority to the port priority it receives in a BPDU

Using the path via the bridge with the lowest bridge ID

#6. You have a switch running IOS 12.4. Which global configuration command will ensure Rapid Spanning Tree is enabled for VLAN 1?

spanning-tree rapid-pvst

spanning-tree mode pvst

spanning-tree mode rapid-pvst

spanning-tree vlan 1 mode rapid-pvst

#7. How frequently does a switch running Rapid Spanning Tree send configuration BPDUs?

Every 1 second

Every 2 seconds

Every 5 seconds

Every 15 seconds

#8. What's the difference between the transmitting bridge ID and the root bridge ID? (Choose two.)

Select all that apply:

The transmitting bridge ID contains information about the switch that sent the BPDU.

The transmitting bridge ID doesn't contain any information about the root.

The root bridge ID contains the base MAC address of the root bridge.

The root bridge ID contains a MAC address based on one of the root bridge's interfaces.

#9. You have three connected switches with the following bridge priorities: SW1: 32788, SW2: 32770, SW3: 36885. There are no other switches in this topology. Which of the following can you conclude from this information? (Choose two.)

Select all that apply:

SW2 is the root for VLAN 20.

SW1 is the root for VLAN 20.

SW2 is in VLAN 2.

SW3 will never be the root.

#10. Consider the following two switches: SW1 has a base MAC address of 0000.1234.ABC9 with a bridge priority of 0. SW2 has a base MAC of 0000.1234.ABCA with a priority of 0. If both switches are placed in the same VLAN, which will become the Spanning Tree root?

SW1

SW2

Neither

Both
