NEW QUESTION 24
Refer to the exhibit.
The exhibit shows the current plan for a wired network upgrade.

Answer: D
NEW QUESTION 25
Read this scenario thoroughly, and then answer each question that displays on the right side of the screen.
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 AirWare
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. 1,000 Access licenses and 3,000 (3x1000) Onboard licenses
- B. 3,000 Access licenses and 3,000 (3x1000) Onboard licenses
- C. 3,000 Access licenses (3x1000) and 1000 Onboard licenses
- D. 1,000 Access licenses and 1000 Onboard licenses
Answer: A

Answer: A,D
NEW QUESTION 28
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. Add two QSPF+ MP0 SR4 transceivers.
- B. Change the power supply type.
- C. Add stacking modules and cables.
- D. Change the v2 modules to v3 modules.
Answer: D
NEW QUESTION 29
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 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.
- B. The Aruba APs and controllers use different prioritization mechanism from WMM, so they will not accept high priority traffic from the wireless devices.
- C. The DSCP values place both voice and video traffic in the video VMM queue, so voice does not receive the prioritization that is should.
- D. DSCP is incompatible with WMM. The Aruba APs and controllers instead use 802.1p to mark traffic to and from wireless devices.
Answer: C
NEW QUESTION 30
An architect plans to deploy a Mobility Controller (MC) at one building in subnet 10.23.01.0/24 and another MC in another building in subnet 10.44.12.0/24. The MCs need to provide redundancy for each other. What must the architect take into account in the redundancy plan?
- A. Each MC can be the backup LMS for the other MCs' APs, but it cannot be in a cluster with the other MC.
- B. The MCs can be in a cluster, but the cluster will not support features such as stateful failover.
- C. The MCs cannot provide any level of redundancy for each other unless one is moved into the other's subnet.
- D. The MCs cannot be in a cluster, and they must use Virtual Router Redundancy Protocol (VRRP) to provide redundancy for each other.
Answer: D
NEW QUESTION 31
