Question: 49

Refer to the exhibit.

A customer needs a wired upgrade for a building on its main campus. The exhibit shows the switches that architect has selected for each closet and the existing cabling. The customer is not open to changing the cabling.

The customer requires link redundancy for the uplinks from each closet and for the links from the building to the core. In non link failure situations, the uplinks from each closet must support at least 20 Gbps, and the building as a whole must have at least 20 Gbps to the core in non link failure situations.

Which options for connecting the closets to the network core are valid? (Select two.)

1. Connect the switch stack on each floor directly to the network core on two fiber connections per floor. Achieve this by patching the inter-floor fiber through the inter-building fiber.

2. Add two aggregation switches in the Floor 1 closet. Connect the switch stack for each closet to the aggregation switches on two fiber links each and the aggregation switches to the core on two fiber links.

3. Combine the nine switches on all three floors into a single switch stack with stacking cables in a ring topology. Connect two Floor 1 members to the network core with one fiber connection each.

4. Combine the nine switches on all three floors into a single switch stack with the MM OM3 fiber cables in a ring topology. Connect two Floor 1 members to the network core with one fiber connection each.

5. Connect the Floor 2 switch stack to Floor 1 with two fiber connections. Do the same for Floor 3. Connect the Floor 1 switch stack to the network core with two fiber connections.

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?

1. This solution will require about 6 battery-powered beacons, which can be managed by the APs.

2. While these APs cannot act as beacons, they have a USB slot that accepts USB beacons.

3. The customer can enable the built-in BLE capability in the AP-335 radio to meet these requirements.

4. The customer must remember to purchase a Meridian Maps license with the Campaigns license.

Answer: A

Question: 52

Refer to the exhibit.

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?

1. whether the hotel wants to deploy the APs as RAPs or CAPs

2. whether the hotel has CAT5e patch cables long enough to reach the boxes

3. whether directional or omnidirectional external antennas work better for the APs

4. whether the hotel already has a PoE or PoE+ source

Answer: D

Question: 53

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?

1. The current AP placement fails to account for the lead-lined walls that are common in patient and exam rooms.

2. The current AP placement fails to provide adequate signal for the voice communicators in several areas.

3. The current AP placement meets coverage requirements, but does not meet capacity requirements.

4. The current AP placement meets the customer requirements in terms of coverage and capacity.

Answer: D

Question: 54

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.
