HP Aruba Certified Design Expert (ACDX) V8 HPE6-A49 Questions & Answers

  • Question 1:

    A hospital needs a better way to track its inventory, including wireless medical devices that are moved

    around the site a lot.

    Which solution meets these needs?

    A. Aruba asset tags and beacons

    B. Aruba asset tags, APs, and Meridian

    C. Aruba beacons, APs, and AirWave

    D. Aruba beacons and Meridian

  • Question 2:

    Refer to the exhibit.

    A customer needs an AirWave solution that can manage 1000 devices. The customer wants a hardware

    solution and active/standby redundancy for the solution.

    The exhibit shows the BOM that the architect has created.

    Which corrections should the architect make?

    A. Change the active appliance to an Enterprise appliance.

    B. Add 1000 additional AirWave managed device licenses.

    C. Change both of the appliances to Enterprise appliance.

    D. Add a failover license for 1000 managed devices.

  • Question 3:

    The airport needs to support several different SSIDs, including:

    four for individual airlines

    one for the airport as a whole

    one for airport security

    The airport security traffic must terminate on different mobility controllers (MCs) from the rest of the airport

    traffic and be managed entirely separately. Airlines also want to terminate traffic at their MCs.

    The airport MCs and airport security MCs require redundancy while airlines do not.

    Which plan for MCs and Mobility Master (MM) meets the needs of this scenario?

    A. one MCs for the airport, one MC for airport security, and one MC for each of the four airlines with its own SSID, all controlled by the same MM

    B. one MCs for the airport, a cluster of MCs for airport security controlled by a pair of MMs, and one MC for each of the four airlines

    C. a cluster of MCs for the airport, a cluster of MCs for airport security, and one MC for each of four airlines, all controlled by the same MM pair

    D. a cluster of MCs for the airport controlled by an MM pair, a cluster of MCs for airport security controlled by a different MM pair, and one standalone MC for each of the four airlines.

  • Question 4:

    A customer requires new MCs for a large multi-site network with about 600 AP-345s and 30,000 wireless clients. The customer requires redundancy for the MCs with each MC being able to handle the full load 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 enough APs and wonders why the architect recommended the 7240XMs.

    What should the architect explain?

    A. The 7240XMs MCs are required to support the large number of wireless clients in this network.

    B. The 7240XMs MCs support 40GbE ports, which are desirable for future proofing.

    C. The 7240XMs MCs can support full CPSec tunnels with this number of APs, while the 7220 MCs cannot.

    D. The 7240XMs MCs have more advanced clustering and availability capabilities than the 7220s MCs.

  • Question 5:

    A retailer has many small outlets. Each outlet has: a local Internet connection, but no local services. The outlets have no local IT staff. All traffic must go through the main office. Devices at the site are primarily POS systems.

    The retailer currently has a complex VPN solution, but would like to: Shift entirely to wireless devices with a new 802.11ac network Simplify network setup for existing and new outlets

    The architect has examined the sites and determined that each will require about 1 to 3 APs. The customer wants the most cost-effective solution that meets the requirements.

    Which solution should the architect recommend for each remote site?

    A. Instant APs (IAPs) with CPSec control channels to Aruba Central

    B. Campus APs (CAPs) with CPSec control channels to a main office MC

    C. Remote APs (RAPs) with IPsec tunnels to a main office MC

    D. Campus APs (CAPs) with a local MC that has an SD-WAN license

  • Question 6:

    What is one requirement for ensuring that MCs can update their software without the need for a maintenance window?

    A. MCs must be managed by an MM and connected to the same switch.

    B. MCs must be in a cluster and connected in the same VLANs.

    C. MCs must be directly connected on at least one port.

    D. MCs must have AP licenses assigned to them in a dedicated local pool.

  • Question 7:

    Case study

    A customer needs a wireless network upgrade for 802.11ac and possibly an upgrade to the wired network.

    The customer requires dual-radio 802.11ac APs, each radio of which can support 4x4 MIMO at full feature

    set.

    The customer has given architects this information about their wireless devices:

    2700 IoT devices which will have only wireless connections; they support WPA2 with 802.1X

    300 on each floor in 3 buildings with 3 floors each

    5,400 users, who use devices such as laptops and smartphones

    600 users on each floor in 3 buildings with 3 floors each

    24 security cameras which will have only wireless connections; they support WPA2 with 802.1X and have

    a local power source

    4 on floor 1 of each of the 3 buildings

    2 on the other 6 floors

    The architect also has collected information about the existing wired network.

    The existing access layer switches support these features:

    10/100/1000 edge ports

    PoE (802.3af)

    1GbE fiber uplinks

    The existing aggregation switches support these features:

    1/10GbE fiber ports

    ARP tables up to 64,000

    The customer has provided this figure that shows the existing cabling between floors and between

    buildings:

    Each floor is about 100 feet (30 m) by 140 feet (43 m) with a 10 foot (3 m) ceiling. Interior walls are drywall. The layout for each floor is similar to that shown below. CAT5e cable is extended to all areas.

    The customer wants to have a wired upgrade as well. The customer has indicated some additional requirements for the wired network, including redundancy for all switch-to-switch links. The customer also wants to explore whether the aggregation layer in buildings can be eliminated.
