(Scenarios may contain multiple errors which may or may not impact the solution)

Refer to the Exhibit.

An engineer has attempted to configure two pairs of switches m the referenced configuration it Is required to implement

Multi-Chassis Link Aggregation for each pair of switches

The ports of the Aruba 8325 switches used for Agg01 and Agg02 are populated as follows

The configuration includes:

There is an error message stating "mismatched group speed" What should you add to the configuration to correct the error?

A.

"system Interface-group 1 speed I0g"

B.

"allow-unsupported-transceiver

C.

"speed 10-full" under interfaces 1/1/12 and 1/1/13

D.

"speed 40-full" under interfaces 1/1/49 and 1/1/50

The customer is considering Implemented the following VSX configuration that will host an Aruba mobility cluster servicing 9000 dual stack employee devices.

The client's default gateways will be hosted on the VSX stack. The customer is seeking advice about how to ensure ArubaOS-CX VSX best practices have been applied.

What advice can you offer the customer? (Select two)

A.

The ISL Bandwidth should be upgraded

B.

Agg-1 and Agg-2's hardware forwarding table profile should be changed to "L3-agg''.

C.

The -system-mac' of Agg-1 should be changed to an unused address from the unicast private address range

D.

The vsx linkup-delay timer is unnecessarily high; it should be reduced to prevent excessive delay of packet forwarding when a VSX peer joins an existing master.

E.

The Keepalive interface should be changed to interface LAG2 so there is redundancy through the mobility cluster.

F.

The keepalive subnet is misconfigured, it has an inappropriate address on Agg-1.

You have designed a new wired solution for a customer that uses gateways and Dynamic Segmentation Which statements about User-Based Tunneling are true? (Select two)

A.

In U8T, the switch performs user authentication.

B.

in UBT, the Aruba Gateway performs user authentication

C.

UBT is supported only with Aruba Gateway standalone

D.

in UBT, the switch sends user role Information to Aruba Gateway

E.

In UBT, the Aruba Gateway assigns the Primary user role

A client connected to Aruba CX 6300 on Port vt/2 Is having issues connecting to a remote destination 10 100 10 62 port 443. How should you get session-specific diagnostic information about this connection?

A.

Use diag utilities tcpdump desttnation-ip 10 10010.62 to capture the session

B.

Use diag utilities tcpdump destination-prefix 10 100 10.62/32 to capture the session

C.

Run tcpdump -interface "1/1/2" host 10.100 10.62 to capture the session

D.

Enter diag-mode and execute tcpdump ip.addr==10.100.10.62.

Refer to the exhibit.

You want to protect the aggregation layer if the VSXISL falls. Where should you place a VSX keepalive link?

A.

On VSX LAG 1

B.

On a dedicated link created using port 1'1/48 of each aggregation switch

C.

On the OOBM ports of both aggregation switches

D.

On VSX LAG 101

A customer would like to utilize some ArubaOS-CX 8325 switches to discard unwanted traffic to the IP address 10 20.30 40.

You enter the following command on the switch:

Ip route 10.20.30.40/32 blac

What will be the result?

A.

The switch will not discard packets to the destined host

B.

The switch will discard packets to the destined host and create a tog message

C.

The switch will discard packets to the destined host silently

D.

The switch will discard packets to the destined host and return ICMP error to the sender.

A customer is migrating from a Cisco VSS system to an ArubaOS-CX VSX cluster in order to provide default gateway functionality, the local network administrator creates VLAN interfaces The network administrator then migrates successfully from Cisco to Aruba

The next day a manager asks if the solution is redundant. The network administrator realizes that there is no redundancy on the default gateway functionality

What is the preferred solution with the least amount of configuration and disturbance?

A.

Remove the IP address on every VLAN interface, and replace it with another one in the same subnet Configure active gateway IP with the default gateway address on every VLAN interface on Doth switches

B.

For every VLAN Interface, configure a VRRP IP address with the same IP address as already present in the first VSX node. Configure this on both switches.

C.

Remove the IP address on every VLAN interface, and replace it with another one in the same subnet Configure VRRP with the default gateway address as virtual IP-address per VLAN.

D.

For every VLAN interface, configure an active gateway IP with the same IP address as already present in the first VSX node Configure this on both switches

Company A and Company B are merging their BGP routed networks The companies have overlapping IP ranges and security concerns during the migration phase. Which Aruba CX 8325 functionality would help the merging of networks in a secure way?

A.

Use of ACL's to separate the company networks at the VLAN level

B.

Use of Aruba Gateway appliance to control the routes between merged networks

C.

Use of vsf capable switch to integrate the routing

D.

Use of virtual route forwarding and BGP route leaking
