HPE6-A41: Applying Aruba Switching Fundamentals for Mobility

A network administrator needs to configure a link aggregation on an ArubaOS switch.

For which type of link aggregation is the administrator required to enter the lacp command in the interface context?

a distributed LACP link aggregation
a dynamic LACP link aggregation
a static LACP link aggregation
a manual LACP link aggregation

Correct answer: B

Refer to the exhibit.

Spanning tree runs on the switches shown in the exhibit. The network administrator enters these two commands:

Switch-1(config)# spanning-tree priority 0

Switch-2(config)# spanning-tree priority 1

The other switches use the default spanning tree priorities. The administrator enters the show spanning-tree command on Switch-2.

If the configuration is correct, which roles will the output show?

A1 = Designated A2 = Alternate A3 = Alternate
A1 = Root A2 = Designated A3 = Designated
A1 = Designated A2 = Designated A3 = Designated
A1 = Root A2 = Alternate A3 = Alternate

Correct answer: B

Refer to the exhibit.

The network administrator enters this command:

Switch(config)# ip route 172.16.2.0/30 192.168.1.100 metric 1 distance 1

Why does this route fail to appear in the IP routing table?

Its prefix length is invalid.
Its next hop is unreachable.
Its administrative distance is the same as an existing static route.
Its metric is the same as an existing static route.

Correct answer: B

Refer to the exhibit.

Exhibit 1.

Exhibit 2.

Which devices can communicate with each other at Layer 2?

Devices 1 and 2 can communicate at Layer 2; Devices 3 and 4 can communicate at Layer 2.
Devices 2 and 3 can communicate at Layer 2.
Devices 1 and 4 can communicate at Layer 2.
Devices 1 and 4 can communicate at Layer 2; Devices 2 and 3 can communicate at Layer 2.

Correct answer: C

Refer to the exhibit.

Exhibit 1.

Exhibit 2.

The routing configuration must support this behavior:

Server 1 and Server 2 communicate over Link 1 when Link 1 is up.

If Link 1 fails, Server 1 and Server 2 can continue to communicate over the path through Switch-3.

What must the network administrator change to meet these criteria?

On Switch 3, add a route to 192.168.2.0/24 through 192.168.1.9 and a route to 192.168.3.0/24 through 192.168.1.5.
On Switch-1, Switch-2, and Switch-3, change the next hop in each static route to specify an IP address that exists on that switch.
On Switch-1, raise the administrative distance for the second route to 192.168.3.0/24; on Switch-2, raise the administrative distance for the second route to 192.168.2.0/24
On Switch-1, add a route to 192.168.1.8/30 through 192.168.0.3; on Switch-2, add a route to 192.168.1.4/30 through 192.168.1.1; on Switch-3, add a route to 192.168.1.0/30 through 192.169.1.4.
On Switch-1, add a route to 192.168.1.8/30 through 192.168.1.2; on Switch-2, add a route to 192.168.1.4/30 through 192.168.1.1; on Switch-3, add a route to 192.168.1.0/30 through 192.168.1.4.

Correct answer: C

A network administrator plans to set up a WLAN on an Aruba Instant cluster. The WLAN uses WPA/WPA2 Enterprise security. The administrator wants no authenticate users locally on the cluster.

How should the administrator configure me credentials?

Add a user account for each employee to the cluster internal server database.
Import authorized device MAC addresses to the cluster.
Implement a shared secret or password in the cluster WLAN settings.
Set up an external RADIUS server for authorization.

Correct answer: D

How does a switch treat a link aggregation?

The switch treats the link aggregation as one logical link for spanning tree, but it learns MAC addresses separately on each individual interface within the aggregation.
The switch treats the link aggregation as one logical link. It assigns one spanning tree port role to the link aggregation, and it learns MAC addresses on the aggregation.
The switch treats the link aggregation as one logical link for MAC learning, but it assigns an individual spanning tree port role to each interface within the aggregation.
The switch treats each interface within the interface as a separate entity for MAC address learning; it also assigns an individual spanning tree port role to each interface.

Correct answer: B

A network administrator needs to configure a static route.

What should the administrator use as the next hop address?

the lowest IP address on the neighboring router in the path towards its destination
the IP address on the local interface that is used to egress traffic towards its destination
the IP address of the default gateway in the destination subnet
the IP address on the connected interface of a neighboring router in the path towards its destination

Correct answer: D

A network administrator just received two switches and wants to use the plug-and-play method to establish a Virtual Switching Framework (VSF) fabric with the fewest steps possible.

What must the administrator do to establish the fabric in this way?

Configure a VSF link on the commander, and enable VSF on the standby member.
Configure a VSF link on the commander, and enable VSF on me commander.
Enable VSF on both me commander and the standby member.
Configure a VSF link on both the commander and the standby member.

Correct answer: B
