Answer : B
Question 4
An architect needs to plan a very high density (VHD) wireless network at a large events venue, at which thousands of attendees are expected. The architect plans to deploy a cluster of Mobility Controllers (MCs) to control the APs. It is important to support seamless roaming for wireless devise across the venue.
What should the architect ensure for the network services?
- A. DHCP servers can support a high number of scopes with a /24 size.
- B. A third-party firewall integrates with ClearPass to filter the guest user traffic.
- C. A domain CA is set up to deploy certificates to a high volume of guest devices.
- D. DHCP and DNS servers are carrier-grade and support a low transaction time.
Answer : B
Question 5
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?
- A. 60 Gbps
- B. 160 Gbps
- C. 200 Gbps
- D. 320 Gbps
Answer : C
Question 6
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?
- A. Use EAP-TLS instead of PEAP-MSCHAPv2
- B. Use TKIP encryption instead of AES.
- C. Add WPA2-PSK as an alternative to WPA2-Enterprise.
- D. Add Tunneled TLS (TTLS) as an alternative to PEAP-MSCHAPv2.
Answer : D
Question 7
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?
- A. 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.
- B. 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.
- 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 : A
Question 8
An architect has an Instant AP (IAP) cluster at a mid-sized branch office. The IAP cluster now needs to tunnel corporate traffic to a Mobility Controller (MC) at the main office. However, the branch office should remain functional even if the link to the main office fails. Users at the branch office require access to main office resources, but do not require multicast services.
What is the recommended DHCP mode?
- A. Local
- B. Centralized L2
- C. Distributed L2
- D. Distributed L3
Answer : D
Question 9
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?
- A. The MCs provide the default gateway services for wireless devices and use static routers.
- B. The MCs act at Layer2, and the MM acts as the default gateway.
- C. The MCs act at Layer2, and core routing switches act as the default gateway.
- D. The MCs provide the default gateway services for wireless devices and use OSPF.
Answer : B
Question 10

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?
- A. stacking modules and cables
- B. stacking licenses
- C. 10 GbE direct attach cables

- C. Airtime Fairness set to fair-access
- D. Voice-aware Layer 3 roaming

- A. Aruba remote APs
- B. Aruba campus APs and a Virtual Mobility Controller
- C. Aruba Instant APs

- B. the need for clustering
- C. the number of devices required
- D. the number of APs required
Answer : C
Question 15
An architect proposes Aruba 2930F switches, which do not have OOBM ports. The customer wants to follow best practices for network management security.
