Question 1

What is one important guideline for antenna selection?

Accepted Answer

The antenna must be designed for the specific frequency range used by the radio to ensure optimal performance and compatibility.

Question 2

Question 8

A customer has several clusters of Aruba 325 Instant APs. The customer is happy with the performance of the current APs, but would like to add a Mobility Controller (MC). What should the architect propose?

Accepted Answer

A VMC can be licensed to control Instant APs, allowing the customer to add a Mobility Controller to their existing Instant AP deployment without having to purchase new APs.

Question 9

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 why a site survey is desirable to determine the optimal locations for the new APs?

Accepted Answer

The answer of A customer needs an 802.11ac upgrade for...

Question 10

A plan includes these security settings for the employee WLAN: WPA2-Enterprise with AES encryption 802.1X with PEAP-MSCHAPv2 However, the customer wants to use certificates to authenticate user devices. Which change brings the plan in alignment with the customer requirements?

Accepted Answer

The answer of A plan includes these security settings for...

Question 11

What should an architect use as a guideline to determine when to minimize VLANs in a wireless design?

Accepted Answer

The answer of What should an architect use as a...

Question 12

An architect proposes Aruba 2930F switches, which do not have OOBM ports. The customer wants to follow best practices for network management security. Which guideline can the architect follow?

Accepted Answer

Assigning access layer switches IP addresses on a VLAN dedicated for switch management helps to isolate management traffic from user data traffic, enhancing security and following best practices for network management.

Question 13

An architect simulates VoIP calls and tests the throughput as 67 Kbps, packet loss as 0.3 percent, maximum latency as 100 ms, and maximum jitter as 100 ms. Which issue typically causes a poor experience for users?

Accepted Answer

Jitter, which is the variation in packet arrival times, can significantly affect the quality of VoIP calls, leading to choppy audio and poor user experience.

Question 14

What is a key criteria that an architect should use to choose between an Aruba 7000 Series or 7200 Series Mobility Controller (MC)?

Accepted Answer

The number of wireless devices that the MC needs to support is a key criterion because the 7000 Series and 7200 Series have different capacities for handling wireless clients.

Question 15

An architect plans where to deploy new Aruba 320 Series APs at a customer site. The architect plans for the APs to be installed on the ceiling where power is inaccessible. The Ethernet cable run to these locations is CAT6, and the customer wants to support at least 1 GbE connectivity. The architect plans to connect each AP with one Ethernet port to a switch in a nearby wiring closet. Which feature does the switch need to support for this deployment?

Accepted Answer

The switch needs to support PoE+ (Power over Ethernet Plus) to provide power to the APs through the Ethernet cable, as power is inaccessible at the ceiling installation locations.

Question 16

An Aruba wireless solution for a very high density (VHD) wireless solution consists of a Mobility Master (MM) and two Mobility Controllers (MCs). What is the best practice design for routing the wireless traffic?

Accepted Answer

The answer of An Aruba wireless solution for a very...

Question 17

An architect plans 128 APs to support 12,800 devices in a very high density (VHD) design. The customer requires high availability, so the architect plans to recommend a pair of controllers. What is one reason to recommend 7210 controllers rather than 7205 controllers for this deployment?

Accepted Answer

The 7210 controllers are recommended over the 7205 controllers due to their ability to handle a larger number of devices, which is crucial for supporting the 12,800 devices in this high-density deployment.

Question 18

Refer to the exhibit.  An architect selects 5406R switches for the aggregation layer. What is an appropriate amount of bandwidth for the link aggregation between each aggregation layer VSF fabric and the campus core?

Accepted Answer

The answer of Refer to the exhibit.  An architect...

Question 19

Refer to the exhibits. Exhibit 1.  Exhibit 2.  Exhibit 1 shows the logical plan, and Exhibit 2 shows the BOM that the administrator has made in Iris. What is missing from the IRIS BOM?

Accepted Answer

Question 20

A customer needs a networking solution that supports their Microsoft Skype for Business Unified Communications (UC) solution. The architect discovers that user wireless devices are Wi-Fi Multimedia (WMM) capable. Windows policies assign voice traffic DSCP 46 and video traffic DSCP 34. Which potential issue should the architect explain to the customer about the default QoS settings?

Accepted Answer

The DSCP values place both voice and video traffic in the video WMM queue, so voice does not receive the prioritization that it should.
