HP Aruba Certified Design Expert Written Sample Questions:

Question 1

The architect plans to recommend an upgrade to Aruba CX switches
What is one requirement for the new solution that justifies this recommendation?

A. the requirement to support smart Rate at the access layer
B. the requirement to support larger ARP tables at the aggregation layer
C. the requirement to support tunneled-node at the access layer
D. the requirement to support secure IPsec tunneling at the aggregation layer

Question 2

A customer requires new MCs for a large multi-site network with about 600 AP-535S ana 30,000 wireless clients. The customer requires redundancy for the MCs, with each MC being able to handle the full toad in a failover situation The network should be able to sustain the loss of a controller with stateful failover within seconds. It should be able to undergo software upgrades without downtime.
The architect has recommended two 7240XM MCs. The customer points out that 7220 MCs can support their requirements and wonders why the architect recommended me 7240XMS.
What should the architect explain?

A. The 724QXM MCs can support full CPSec tunnels with this number of APs. while the 7220 MCs cannot.
B. The 7240XM MCs have better redundant power supplies and fan tray component capabilities than 7220 MCs.
C. The 7240XM MCS provide a higher number of concurrent GRE tunnels to support 600APs with MCS in L2 clustering.
D. The 7240XM MCs are required to support the large number of wireless clients in this network

Question 3

Refer to the exhibit.

A customer has these availability requirements;
* loss of one controller with stateful failover and without impact on wireless client connectivity
* loss of one core switch without loss of connectivity for any endpoints or APs in the building
* loss of any one switch-lo-switch or MC-to-switch link without loss of connectivity for any endpoints or APS in the building and with minimal impact on infrastructure functionality
* loss of any one access switch with minimal impact to wireless client connectivity The exhibit shows the current plan for the topology.
Which change should the architect make to the plan to provide better support for the customers availability requirements?

A. Use two 40GBE DACs between the core V3X switches for their switch links.
B. Add 120 additional AP licenses, so that each MC can support ail the APs, even if the other MC fails.
C. Add VLANs 11 and 15 to the MC connections to ensure both MCS can manage any of the APS.
D. Change the 40GbE DAC on the 8400 switch to a stacking cable with stacking module.

Question 4

A customer has an existing; Aruba wireless solution to provide wireless access for employees. The solution Includes Aps, mobility controllers (MCs) at the network core, and a Mobility Master (MM} A customer would like to set up a separatelymanaged guest network and have the traffic go directly to the DMZ.
What should the architect suggest as the simplest solution that meets the requirements?

A. Use MulitZone, and put a mobility controller in Itie DMZ.
B. Add APs in a dedicated AP group to support only the guest network SSID.
C. Have a dedicated mobility controller in the DMZ managed by the same MM
D. Double the number of APs and controllers.

Question 5

An indoor basKetbaiI stadium has 5.000 seats in two rings:
* The stadium has a ceiling height of GO feet (18 m).
* There is a catwalk around the perimeter of the basketball court, between the court and the seating areas.
* This catwalk is 40 feet (12 m) from the floor.
* There are two scoreboards at either end of the stadium.
* The construction of the stadium is concrete and sleet.
The customer does not want an under-seat, picoceli deployment.
Which AP model is appropriate to provide coverage in the main stadium bawl?

A. AP-555
B. AP-575
C. AP-577
D. AP-505
