NEW QUESTION 20
A customer requires a wireless upgrade. The architect proposes:
* Aruba AP-325s
* Mobility Controller (MC) 7210s
* Virtual Mobility Masters (MMs)
* ClearPass
* AirWave
The customer is interested in wired authentication, as well as wireless authentication, but does not have the budget to upgrade the wired network. The wired network does not currently support 802.1X or RADIUS.
Which feature of the Aruba solution should the architect explain to justify the proposed solution?
- A. The customer can direct all wired traffic through the MCs, which will then apply security to that traffic.
- B. The customer can direct all wired traffic through the MMs, which will impose basic security checks.
- C. AirWave can manage these switches and shut down their ports if an unknown user or device connects.
- D. ClearPass OnConnect can enable wired authentication on these switches through the use of SNMP.
Answer: D
NEW QUESTION 21
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?
- A. OSPF graceful restart
- B. VRRP
- C. BGP
- D. SmartLink
Answer: C
NEW QUESTION 22
Which guidelines should an architect use to determine how many AirWave servers to recommend?
- A. One server should be dedicated to the wired infrastructure and one server to the wireless infrastructure.
- B. One server should monitor and manage up to about 4,000 infrastructure devices.
- C. One server is recommended for the base features and one server each for add-on features such as Clarity.
- D. One server should be deployed on every subnet with an infrastructure device.
Answer: D
NEW QUESTION 23
Refer to the exhibit.
Exhibit 1 shows the logical plan, and Exhibit 2 shows the BOM created with IRIS. An architect plans to propose two 5406Rzl switches as a VSF fabric for a campus network core. Which issue with the plan should the architect correct?
- A. Change the power supply type.
- B. Add two QSPF+ MP0 SR4 transceivers.
- C. Change the v2 modules to v3 modules.
- D. Add stacking modules and cables.
Answer: C
NEW QUESTION 24
Scenario:
An architect proposes these products for a customer who wants a wireless and wired upgrade:
* Aruba 2930M switches at the access layer
* Aruba 5406R switches at the core
* Aruba AP-325s
* Aruba 7205 Mobility Controllers (MCs), deployed in a cluster
* Aruba Mobility Master (MM)
* Aruba ClearPass Cx000V
* Aruba AirWave
The architect also needs to propose a security plan for the solution. The customer has 900 employees and up to 30 guests a day. The customer wants to protect the internal perimeter of the network with authentication and simple access controls. The customer is most concerned about wireless security, but also wants to ensure that only trusted users connect on the wire. However, the customer also wants all wired traffic to be forwarded locally on access layer switches. The customer already has a third-party firewall that protects the data center.
The customer wants to use certificates to authenticate user devices, but is concerned about the complexity of deploying the solution. The architect should recommend a way to simplify. For the most part users connect company-issued laptops to the network. However, users can bring their own devices and connect them to the network. The customer does not know how many devices each user will connect, but expects about two or three per-user. DHCP logs indicate that the network supports a maximum of 2800 devices.
Refer to the provided scenario. Which ClearPass licenses should the architect include in the proposal?
- A. 3,000 Access licenses and 3,000 (3x1000) Onboard licenses
- B. 1,000 Access licenses and 1000 Onboard licenses
- C. 3,000 Access licenses (3x1000) and 1000 Onboard licenses
- D. 1,000 Access licenses and 3,000 (3x1000) Onboard licenses
Answer: D
NEW QUESTION 25

1. Two Virtual Mobility Masters (VMMs)
2. Six 7030 Mobility Controllers (MCs)
3. 300 APs
In addition to any necessary AP, PEF, and RFP licenses, which license package should the architect propose?
- A. one LIC-MC-VA-250 and one LIC-MC-VA-50; one LIC-MM-VA-500
- B. one LIC-MC-VA-250 and one LIC-MC-VA-50; six LIC-MM-VA-500
- C. six LIC-MM-VA-50
- D. one LIC-MM-VA-500
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
NEW QUESTION 28
A customer has very high availability requirements for wireless services. The architect plans to implement clustering on several Aruba Mobility Controllers (MCs).
Which benefit of this feature should the architect explain?
- A. Clustering enables an AP with a failed MC to operate on its own briefly to ensure seamless connectivity.
- B. Clustering enables an AP with a failed MC to reconnect to a new AP after a short bootstrap.
- C. Clustering provides high stability because one MC is active for all sessions and one is standby for all sessions.
- D. Clustering provides wireless client load balancing and seamless failover for client sessions.
Answer: C

The customer has an office environment with users who have laptops that can connect with wired or wireless.
Users also bring one or two of their own devices. An architect creates a proposal with Aruba AP-325s, 7210
Mobility Controllers (MCs), a Mobility Master (MM), and Aruba 2930M switches at the access layer to
support the laptops and APs.

that connect to laptops. What is one advantage of this form of authentication?
- A. ensures that Aruba firewall policies apply to wired user traffic.
- B. prevents users from connection attempts with more than three devices

- B. The RAP uses UDP 4500 to send traffic to the controller.
- C. User Traffic is CPSec encrypted before it is sent to the controller.
- D. The user role must have a "Permit" statement in order to locally bridge the traffic.

NEW QUESTION 35
A customer needs a solution to terminate VPN tunnels for Aruba RAPs. The customer has a single site and a
single public IP address for this purpose. Network address translation (NAT) will forward the IPsec traffic to
the correct device to terminate the VPN tunnel. The customer also requires N+1 redundancy for the solution.
Which solution meets the customer requirements?
- A. two Aruba MCs deployed as a Layer 2 cluster
- B. two Aruba MCs deployed as a Layer 3 cluster
- C. two Aruba MCs on the same subnet that use VRRP without clustering
- D. two Aruba MCs on different subnets that use VRRP without clustering
Answer: B
NEW QUESTION 36
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?
- A. The Aruba APs and controllers use different prioritization mechanism from WMM, so they will not
accept high priority traffic from the wireless devices. - B. The DSCP values place both voice and video traffic in the video VMM queue, so voice does not receive
the prioritization that is should. - C. DSCP is incompatible with WMM. The Aruba APs and controllers instead use 802.1p to mark traffic to
and from wireless devices. - D. The DSCP for wireless client traffic is concealed within the GRE packet on the path from the AP to the
controller, and does not take effect.
Answer: B
NEW QUESTION 37

- B. During normal operation, the AMs can support clients, as well as detect and mitigate threats on any channel.
- C. An AM can help in troubleshooting because it stores detailed statistics about wireless traffic locally.
- D. If a nearby AP fails, the AM can automatically convert to AP mode to fill in the coverage gap.
Answer: D
