A hospital needs an upgrade to 802.11ac for its wireless network. The wireless network supports:
✑ wireless medical devices
✑ medical staff voice communicators
✑ laptops in nurse stations
✑ medical staff tablets
✑ visitor and patient personal devices
All of these devices support both the 2.4GHz and 5GHz band. Assuming about a max throughput of 150 Mbps per AP, the hospital would like to support about 4
Mbps per client.
The architect has used VisualRF to plan the AP placement on one of the floors, which the hospital expects will need to support about 800 wireless devices. The exhibits show heatmaps from this plan. The architect also plans to deploy APs in stairwells between floors.
How well does the plan meet the requirements?
Correct Answer: C
The current AP placement meets coverage requirements, but does not meet capacity requirements. Given that each AP can provide a maximum throughput of about 150 Mbps and the requirement is to support 800 devices at 4 Mbps per client, the total required throughput is 800 devices * 4 Mbps = 3200 Mbps. This would necessitate approximately 3200 Mbps / 150 Mbps per AP = about 21.3, or 22 APs. The heatmap shows coverage but may not indicate if there are enough APs for the required capacity. Hence, the placement appears to meet coverage but does not adequately address the capacity requirements.
An indoor sports stadium has 5,000 seats in two rings:
✑ The stadium has a ceiling height of 60 feet (18m).
✑ There is a catwalk around the perimeter of the court, between the court and the seating areas. This catwalk is 40 feet (12m) from the floor.
✑ There are two scoreboards at either end of the stadium.
✑ The construction of the stadium is concrete and steel.
The customer does not want an under-seat, pico cell deployment, and the customer requires 802.11ac Wave 2.
Which AP model is appropriate to provide coverage in the main stadium bowl?
Correct Answer: B
Considering the requirements, the appropriate AP model for providing coverage in the main stadium bowl is one that supports 802.11ac Wave 2, which is crucial for high-density environments like an indoor sports stadium. The AP-344 is a suitable choice as it meets the necessary requirements for 802.11ac Wave 2, ensuring reliable and high-performance wireless connectivity, which is essential for the given scenario.

A customer has a wired infrastructure shown in the exhibit. The customer is in the process of expanding their wireless services. They will now add a new wireless solution, with mobility controllers (MCs) connected as shown. The new wireless solution will support a total of 450 APs and about 26,000 wireless devices. It must provide seamless roaming across the entire campus.
After the new deployment, both wired and wireless devices experience IP connectivity issues.
Which change to the existing infrastructure should the architect recommend to support all of the customer requirements?
Correct Answer: C
The customer is experiencing IP connectivity issues due to the expansion of their wireless services, which suggests that the core switches might be reaching their limit in terms of handling ARP entries, given the large number of devices (about 26,000 wireless devices) the network needs to support. The 5400R switches currently used might not have a sufficient ARP table size to manage the increased number of devices. Therefore, replacing the core switches with switches that have larger ARP tables would address the ARP capacity issue, thereby supporting the increased number of connected devices and ensuring seamless connectivity.

A casino and a retail space has an existing Aruba network with Aruba AP-335s. The customer wants to deploy Meridian and enable proximity-based campaigns.
The exhibit shows a segment of the floor plan. When visitors enter the areas circled in the exhibit, they should receive a targeted notification about promotions and sales.
What should the architect explain to the customer about how to finish the solution?
Correct Answer: C
The Aruba AP-335 access points have built-in Bluetooth Low Energy (BLE) capabilities. These capabilities can be enabled in the AP-335 radio to support proximity-based campaigns and targeted notifications without the need for additional battery-powered beacons or USB beacons. This solution leverages the existing hardware to meet the customer's requirements.

A hotel needs a wireless solution. The architect has selected 303H Series, controlled by a local MC, as the best choice. The hotel plans to have the APs installed in the existing wall boxes which have one Ethernet port each.
The architect has created to BOM shown in the exhibit. (Note that this portion of the BOM does not include the MC, which is not part of this question.)
Which additional clarification should the architect seek to determine whether this BOM fully meets the customer needs?
Correct Answer: D
To ensure that the wireless solution will function properly, it is crucial to confirm whether the hotel has a PoE (Power over Ethernet) or PoE+ source. The AP-303H APs require PoE for power, and without a sufficient PoE or PoE+ source, the APs will not operate. Clarifying this ensures that the necessary power infrastructure is in place to support the deployment of the selected APs.
