Exam Simulator: VLANs and STP Implementations

Question 1 of 15

1. Question

Which of the following commands identify switch interfaces as being trunking interfaces that currently operate as VLAN trunks? (Choose two answers)

show interfaces
show interfaces switchport
show interfaces trunk
show trunks
show vlan

Question 2 of 15

2. Question

One of the most common reasons for choosing to create smaller broadcast domains (VLANs) is to reduce CPU overhead on each device, improving host performance, by reducing the number of devices that receive each broadcast frame.

True
False

Question 3 of 15

3. Question

The senior network engineer assigned you the following task:

Create a VLAN with vlan-id 4
Name the VLAN as examsdigest-vlan
Assign the ports Fa0/10 – Fa0/14 to that VLAN
Make the ports always to operate in access mode

examsdigest#

Enter configuration commands, one per line. End with CNTL/Z.

examsdigest(config)#

examsdigest(config-vlan)#

examsdigest(config-vlan)# exit

examsdigest(config)#

examsdigest(config-if)#

examsdigest(config-if)#

examsdigest(config-if)# end

The following diagram illustrates a LAN design with data in VLAN 6 and phones in VLAN 5. Using the diagram below configure the Switch using ports F0/3 – F0/5 to match the LAN design.

Question 5 of 15

5. Question

Sort the following steps (from step 1 to step 4) in order to troubleshoot VLANs and VLAN Trunks

Check for incorrect trunk configuration settings that result in one switch operating as a trunk, with the neighboring switch not operating as a trunk.
Confirm that all VLANs are both defined and active.
Check the native VLAN settings on both ends of the trunk to ensure the settings match.
Check the allowed VLAN lists on both ends of each trunk to ensure that all VLANs intended to be used are included.

Question 6 of 15

6. Question

STP has completed convergence, which of the following port states are stable states? (Choose two answers.)

Learning
Discarding
Blocking
Forwarding
Transitioning

Question 7 of 15

7. Question

Which of the following bridge IDs wins election as root, assuming that the switches with these bridge IDs are in the same network?

4096:0200.1111.3333
4096:0200.1111.2222
4096:0200.1111.1111
4096:0200.1111.4444

Question 8 of 15

8. Question

Which of the following are transitory port states used only during the process of STP convergence? (Choose two answers.)

Listening
Learning
Discarding
Blocking
Forwarding

Question 9 of 15

9. Question

Match the three problems caused by not using STP in redundant LANs with their descriptions.

Sort elements

Broadcast storms
Multiple frame transmission
MAC table instability

The forwarding of a frame repeatedly on the same links, consuming significant parts of the links’ capacities.
A side effect of looping frames in which multiple copies of one frame are delivered to the intended host, confusing the host.
The continual updating of a switch’s MAC address table with incorrect entries, in reaction to looping frames, resulting in frames being sent to the wrong locations.

Question 10 of 15

10. Question

Match the Ethernet speeds with the RSTP default costs:

Sort elements

20,000
2000
20
200

1 Gbps
10 Gbps
1 Tbps
100 Gbps

Question 11 of 15

11. Question

RSTP and STP elect designated ports on each LAN segment with the same rules and tiebreakers.

True
False

Question 12 of 15

12. Question

STP and RSTP open up the LAN to several different types of possible security exposures. One of the problems is:

An attacker could connect a switch to one of these ports, one with a low STP/RSTP priority value, and become the root switch. The new STP/RSTP topology could have worse performance than the desired topology.

Type the Cisco’s feature that helps defeat the security risk.

Question 13 of 15

13. Question

Type the commands that correspond to the following descriptions.

List details about the state of STP on the switch, including the state of each port.

Change the bridge priority of the switch to 8192 for the VLAN 20

Set the STP mode to pvst

Question 14 of 15

14. Question

Cisco uses the term ‘distribution switch’ to refer to switches used to connect to endpoint devices.

True
False

Question 15 of 15

15. Question

You are responsible to configure a switch to put interfaces F0/1 and F0/2 into the same Layer 2 EtherChannel. Which of the following terms will you use in the configuration commands?

EtherChannel
Channel-group
Ethernet-Channel
PortChannel
