Switch Stack Offline Configuration

You can use the offline configuration feature to provision (to supply a configuration to) a new switch before it joins the switch stack. You can configure in
advance the stack member number, the switch type, and the interfaces associated with a switch that is not currently part of the stack. The configuration
that you create on the switch stack is called the provisioned configuration . The switch that is added to the switch stack and that receives this
configuration is called the provisioned switch.
You manually create the provisioned configuration through the switch stack-member-number provision type global configuration command. The
provisioned configuration is automatically created when a switch is added to a switch stack and when no provisioned configuration exists.
When you configure the interfaces associated with a provisioned switch (for example, as part of a VLAN), the switch stack accepts the configuration,
and the information appears in the running configuration. The interface associated with the provisioned switch is not active, operates as if it is
administratively shut down, and the no shutdown interface configuration command does not return it to active service. The interface associated with the
provisioned switch does not appear in the display of the specific feature; for example, it does not appear in the show vlan user EXEC command output.
The switch stack retains the provisioned configuration in the running configuration whether or not the provisioned switch is part of the stack. You can
save the provisioned configuration to the startup configuration file by entering the copy running-config startup-config privileged EXEC command. The
startup configuration file ensures that the switch stack can reload and can use the saved information whether or not the provisioned switch is part of the
switch stack.
Effects of Adding a Provisioned Switch to a Switch Stack
When you add a provisioned switch to the switch stack, the stack applies either the provisioned configuration or the default configuration. lists the events
that occur when the switch stack compares the provisioned configuration with the provisioned switch.

A network engineer must set the load balance method on an existing port channel. Which action must be done to apply a new load balancing method?
A.
B.
C.
D.

Configure the new load balancing method using port-channel load-balance.
Adjust the switch SDM back to "default".
Ensure that IP CEF is enabled globally to support all load balancing methods.
Upgrade the PFC to support the latest load balancing methods.

Correct Answer: A
Section: Layer 2 Technologies
Explanation
Explanation/Reference:
Example:
EtherChannel balances the traffic load across the links in a channel through the reduction of part of the binary pattern that the addresses in the frame
form to a numerical value that selects one of the links in the channel. EtherChannel load balancing can use MAC addresses or IP addresses, source or
destination addresses, or both source and destination addresses. The mode applies to all EtherChannels that are configured on the switch. You
configure the load balancing and forwarding method with use of the port-channel load-balance {dst-ip | dst-mac | src-dst-ip | src-dst-mac | src-ip |
src-mac} global configuration command.

protocol on this interface to be shown as down?
A.
B.

E.

There is a layer 1 physical issue.
There is a speed mismatch on the interface.
The interface is configured as the target of the SPAN session.
The interface is configured as the source of the SPAN session.
There is a duplex mismatch on the interface.

Correct Answer: C

Explanation
Explanation/Reference:
Explanation:
With the SAPN destination port, the state of the destination port is up/down by design. The interface shows the port in this state in order to make it
evident that the port is currently not usable as a production port. This is the normal operational state for SPAN destinations.

Correct Answer: C
Section: Layer 2 Technologies
Explanation
Explanation/Reference:
Explanation:
By default, a trunk port sends traffic to and receives traffic from all VLANs. All VLAN IDs, 1 to 4094, are allowed on each trunk. However, you can
remove VLANs from the allowed list, preventing traffic from those VLANs from passing over the trunk. To restrict the traffic a trunk carries, use the
"switchport trunk allowed vlan remove vlan-list" interface configuration command to remove specific VLANs from the allowed list.

Correct Answer: A
Section: Layer 2 Technologies
Explanation
Explanation/Reference:
Explanation:
In this case, the port has been configured both as a trunk and as a switchport in data vlan 10. Obviously, a port can not be both, so even though Cisco
IOS will accept both, the port will actually be used as a trunk, ignoring the switchport access VLAN 10 command.

Explanation:
Voice VLAN Configuration Guidelines
·You should configure voice VLAN on switch access ports. The voice VLAN should be present and active on the switch for the IP phone to correctly
communicate on the voice VLAN. Use the show vlan privileged EXEC command to see if the VLAN is present (listed in the display).
·The Port Fast feature is automatically enabled when voice VLAN is configured. When you disable voice VLAN, the Port Fast feature is not
automatically disabled.

Section: Layer 2 Technologies
Explanation
Explanation/Reference:
Explanation:
VTP pruning should only be enabled on VTP servers, all the clients in the VTP domain will automatically enable VTP pruning. By default, VLANs 2 1001 are pruning eligible, but VLAN 1 can't be pruned because it's an administrative VLAN. Both VTP versions 1 and 2 supports pruning.

Which feature must be enabled to eliminate the broadcasting of all unknown traffic to switches that are not participating in the specific VLAN?
A.
B.
C.
D.

VTP pruning
port-security
storm control
bpdguard

Correct Answer: A
Section: Layer 2 Technologies
Explanation
Explanation/Reference:
Explanation:
VTP ensures that all switches in the VTP domain are aware of all VLANs. However, there are occasions when VTP can create unnecessary traffic. All
unknown unicasts and broadcasts in a VLAN are flooded over the entire VLAN. All switches in the network receive all broadcasts, even in situations in
which few users are connected in that VLAN. VTP pruning is a feature that you use in order to eliminate or prune this unnecessary traffic.

Which two options are two results of using the command spanning-tree vlan 50 root primary within a spanning-tree network under global configuration
(Choose two)
A.
B.
C.
D.
E.

The switchport that is configured for VLAN 50 is the primary connection to the spanning-tree root switch
The primary value for VLAN 50 is set to 4094 on the root while the local switch priority is set to 32768
All ports that are configured on the current switch with VLAN 50 transition to designated ports
Spanning tree determines the priority of the current root Vlan 50 and reduces the priority of the local switch to lower value
The spanning-tree timers are reduced to improve the convergences time for Vlan 50

LACP modes:
+ on: the link aggregation is forced to be formed without any LACP negotiation. A port-channel is formed only if the peer port is also in “on” mode.
+ off: disable LACP and prevent ports to form a port-channel
+ passive: the switch does not initiate the channel, but does understand incoming LACP packets
+ active: send LACP packets and willing to form a port-channel
The table below lists if an EtherChannel will be formed or not for LACP:
LACP Active Passive
Active Yes Yes
Passive Yes No
PAgP modes:
