NEW QUESTION 19
An architect needs to plan the bandwidth for two Aruba 7240 Mobility Controllers (MCs) which will connect to the network core. The customer indicates that four 10 GbE links between the network core and the data center will be adequate. The customer expects almost all traffic in the network will be wireless. The customer expects up to 25 Gbps upstream traffic from wireless clients and up to 35 Gbps downstream to wireless clients.

- B. two 10 GbE links on each of the MC
- C. three 10 GbE links on each of the MCs
- D. two 40 GbE links in each of the MCs
Answer: D

- D. LACP
Answer: A
NEW QUESTION 24
Refer to the exhibit.
The exhibit shows the current plan for a wired network upgrade.

- A. Combine the switches in each Building 2 closet as a VSF fabric; establish two 10 GbE connections to the core per fabric.
- B. Connect each Building 2 switch directly to the core on a single fiber strand through the use of SFP+-SR transceivers.
- C. Use two additional 2930F switches to act as an aggregation layer for Building 2; connect them to the core on 40 GbE connections.
- D. Extend additional fiber between the buildings so that each Building 2 switch can have a direct 10 GbE connection to the core.
Answer: A
NEW QUESTION 25
Refer to the exhibit.
The customer requires fast failover if any one link or core device fails. Which additional technology should the architect plan on the core VSF fabric to meet these criteria?

Answer: D
NEW QUESTION 27
A customer needs an 802.11ac upgrade for an office with cubicles. The customer states that, because they
planned locations for the existing 802.11n APs so that there are no coverage holes, they will simply deploy the
new 802.11ac APs in the same location as the existing APs. The customer plans to support mobile devices in
addition to laptops.
What should the architect explain about shy a site survey is desirable to determine the optimal locations for the
new APs?
- A. The new 802.11ac deployment should have a capacity-based design for the best performance, but the
existing deployment sounds like a coverage-based design. - B. An 802.11ac deployment typically works better with side-mounted, rather than ceiling-mounted, APs,
and a site survey will help determine the new mounting locations. - C. 802.11ac AP radios tend to be more sensitive to 2.4 GHz interference than 802.11n APs, so the architect
needs to search for all potential sources of such interference. - D. 802.11ac APs can support a higher density of clients, so they can be deployed farther apart than the APs
in most existing 802.11n deployments.
Answer: B
