Question 1 of 806
What is the maximum number of switches that can be stacked using Cisco StackWise?
Answer

Suggested Answer

The suggested answer is C.

The maximum number of switches that can be stacked using Cisco StackWise is 8. Cisco StackWise technology typically supports up to 8 switches in a single stack, allowing them to function as a single logical unit and be managed using a single IP address. This stack can provide redundancy and increased port capacity.

Question 2 of 806
A network engineer wants to add a new switch to an existing switch stack. Which configuration must be added to the new switch before it can be added to the switch stack?
Answer

Suggested Answer

The suggested answer is A.

Switch Stack Offline Configuration
(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
.
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.

Question 3 of 806
What percentage of bandwidth is reduced when a stack cable is broken?
Answer

Suggested Answer

The suggested answer is C.

Physical Sequential Linkage -
The switches are physically connected sequentially, as shown in Figure 3. A break in any one of the cables will result in the stack bandwidth being reduced to half of its full capacity. Subsecond timing mechanisms detect traffic problems and immediately institute failover. This mechanism restores dual path flow when the timing mechanisms detect renewed activity on the cable.

Question 4 of 806
Refer to the exhibit.
Exam 300-115: Question 4 - Image 1
Which set of configurations will result in all ports on both switches successfully bundling into an EtherChannel?
Answer

Suggested Answer

The suggested answer is D.

The different etherchannel modes are described in the table below:
Exam 300-115: Question 4 - Image 2
Both the auto and desirable PAgP modes allow interfaces to negotiate with partner interfaces to determine if they can form an EtherChannel based on criteria such as interface speed and, for Layer 2 EtherChannels, trunking state and VLAN numbers.
Interfaces can form an EtherChannel when they are in different PAgP modes as long as the modes are compatible. For example:
✑ An interface in the desirable mode can form an EtherChannel with another interface that is in the desirable or auto mode.
✑ An interface in the auto mode can form an EtherChannel with another interface in the desirable mode.
An interface in the auto mode cannot form an EtherChannel with another interface that is also in the auto mode because neither interface starts PAgP negotiation.
An interface in the on mode that is added to a port channel is forced to have the same characteristics as the already existing on mode interfaces in the channel.

Question 5 of 806
Refer to the exhibit.
Exam 300-115: Question 5 - Image 1
How can the traffic that is mirrored out the GigabitEthernet0/48 port be limited to only traffic that is received or transmitted in VLAN 10 on the GigabitEthernet0/1 port?
Answer

Suggested Answer

The suggested answer is C.

To start a new flow-based SPAN (FSPAN) session or flow-based RSPAN (FRSPAN) source or destination session, or to limit (filter) SPAN source traffic to specific
VLANs, use the monitor session filter global configuration command.

Usage Guidelines -
You can set a combined maximum of two local SPAN sessions and RSPAN source sessions. You can have a total of 66 SPAN and RSPAN sessions on a switch or switch stack.
You can monitor traffic on a single VLAN or on a series or range of ports or VLANs. You select a series or range of VLANs by using the [ , | -] options.
If you specify a series of VLANs, you must enter a space before and after the comma. If you specify a range of VLANs, you must enter a space before and after the hyphen ( -).
VLAN filtering refers to analyzing network traffic on a selected set of VLANs on trunk source ports. By default, all VLANs are monitored on trunk source ports. You can use the monitor session session_number filter vlan vlan-id command to limit SPAN traffic on trunk source ports to only the specified VLANs.
VLAN monitoring and VLAN filtering are mutually exclusive. If a VLAN is a source, VLAN filtering cannot be enabled. If VLAN filtering is configured, a VLAN cannot become a source.
