QUESTION 27:
Which Cisco switch command would you use to map VLANs 10 to 20 to MST
instance 1?
A. Switch(config)#vlan 10-20 instance 1
B. Switch(config)#instance 1 vlan 10-20
C. Switch(config-mst)#vlan 10-20 instance 1
D. Switch(config-mst)#instance 1 vlan 10-20
E. None of the above
Answer: D
Explanation:
Beginning in privileged EXEC mode, follow these steps to specify the MST region
configuration and enable MSTP. This procedure is required.
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 spanning-tree mst configuration Enter MST configuration mode.
Step3 instance instance-id vlan vlan-range Map VLANs to an MST instance.
For instance-id, the range is 1 to 15.
For vlan vlan-range, the range is 1 to 4094.
When you map VLANs to an MST instance, the mapping is incremental, and the VLANs
specified in the command are added to or removed from the VLANs that were previously
mapped.
To specify a VLAN range, use a hyphen; for example, instance 1 vlan 1-63maps VLANs
1 through 63 to MST instance 1.
To specify a VLAN series, use a comma; for example, instance 1 vlan 10, 20, 30maps
VLANs 10, 20, and 30 to MST instance 1.
Step4 name name Specify the configuration name. The name string has a maximum
length of 32 characters and is case sensitive.
Step5 revision version Specify the configuration revision number. The range is 0 to
65535.
Step6 show pending Verify your configuration by displaying the pending configuration.
Step7 exit Apply all changes, and return to global configuration mode.
Step8 spanning-tree mode mst Enable MSTP. RSTP is also enabled.
Caution
Changing spanning-tree modes can disrupt traffic because all spanning-tree
instances are stopped for the previous mode and restarted in the new mode.
You cannot run both MSTP and PVST+ or both MSTP and rapid PVST+ at the same
time.
Step9 end Return to privileged EXEC mode.
Step10 show running-config Verify your entries.
Step11 copy running-config startup-config (Optional) Save your entries in the
configuration file.

QUESTION 28:
Which Cisco IOS command assigns a Catalyst switch port to VLAN 10?
A. switchport mode vlan 10
B. switchport trunk vlan 10
C. switchport access vlan 10
D. switchport mode access vlan 10
Answer: C
Explanation:
Switchport access:
Use the switchport access interface configuration command to configure a port as a
static-access port. The port operates as a member of the configured VLAN.
Use the no form of this command to reset the access mode to the default VLAN for the
switch.
Syntax
switchport access vlan vlan-id
no switchport access vlan vlan-id
Syntax Description
vlan vlan-id
ID of the VLAN. Valid IDs are from 1 to 1005. Do not enter leading zeroes.
Defaults
All ports are in static-access mode in VLAN 1.
Command Modes
Interface configuration.
Usage Guidelines
An access port can be assigned to only one VLAN.
When the no switchport access vlan form is used, the access mode is reset to static access
on VLAN 1.
Example
The following example shows how to assign a port to VLAN 2 (instead of the default
VLAN 1):
Switch(config-if)# switchport access vlan 2
You can verify the previous command by entering the show interface interface-id
switchport command in privileged EXEC mode and examining information in the
Administrative Mode and Operational Mode rows.
QUESTION 29:
SIMULATION
You are connected to a Catalyst switch via a console cable as shown below:
You work as a systems administrator at the Certkiller .com main office in the greater
Toronto area. The number of employees on your floor has exceeded the
infrastructure of your current network equipment. Your CTO has ordered a new
switch chassis, but it’s going to be another 6-8 working days until it arrives. In the
meantime you can to connect 24 new workstations to an old Cisco Catalyst 2950,
which your junior administrator has just finished erasing, and rebooting (to purge
old VLAN information).
Your tasks are to:
* disable VTP
* Ensure that all non-trunking interfaces do not participate in Spanning Tree by default
by globally configuring PortFast.
For the following two tasks, you are required to use global commands to configure
the ports:
1. Ensure all FastEthernet interfaces are in permanent non-trunking mode.
2. Place FastEthernet interfaces 0/12 through 0/24 in VLAN 20.
Start by clicking on host CertK iA.
Answer:
Explanation:
enable
configure terminal
Switch(config)#vtp mode transparent (disable vtp)
Switch(config)#spanning-tree portfast default (Globally, enable portfast on all ports)
Switch(config)#interface range fa0/1 – 24 (select interfaces)
Switch(config-if)#switchport mode access (set ports for access mode, NOT Trunking)
switch(config)#interface range fa0/12 – 24 (The 4th task is to “Place FastEthernet interfaces 0/12 through
0/24 in VLAN20″)
switch(config-if-range)#switchport access vlan 20
switch(config-if-range)#end
exit
Switch(config-if)#interface range fa0/12 – 24 (select interfaces)
Switch(config-if)#switchport access vlan 20 (assign ports to vlan 20)
end
copy running-config startup-config
