An architect plant to purpose an Aruba wireless solution with several Mobility Controllers (MCs) and a Mobility Master (MM) architecture. Wireless users run Skype for Business, a Unified Communications (UC) solution. The architect plans to use the Aruba SDN capabilities to integrate with the UC solution.
What helps to support high availability specifically for the SDN services?
A. a redundant master MC
B. backup controllers defines on the APs
C. a cluster deployment for MCs
D. a redundant MM
What typically drives the need for an aggregation layer in modern networks?
A. insufficient fiber cabling, especially between buildings
B. lack of high speed uplink capabilities at the access layer
C. simplification of spanning tree protocol ad the access layer
D. need to extend VLANs across wider areas
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:
1.
Aruba 2930M switches at the access layer
2.
Aruba 5406R switches at the core
3.
Aruba AP-325s
4.
Aruba 7205 Mobility Controllers (MCs), deployed in a cluster
5.
Aruba Mobility Master (MM)
6.
Aruba ClearPass Cx000V
7.
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 1000 Onboard licenses
B. 1,000 Access licenses and 3,000 (3x1000) Onboard licenses
C. 3,000 Access licenses (3x1000) and 1000 Onboard licenses
D. 3,000 Access licenses and 3,000 (3x1000) Onboard licenses
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. SmartLink
C. BGP
D. VRRP
An architect proposes an Aruba wireless solution for a customer that uses Microsoft Skype for Business. What should be set up on the MCs, or MM, to ensure that wireless voice traffic is properly prioritized?
A. Firewall policies and SDN to mark voice
B. Broadcast suppression combined with AirGroup
C. Airtime Fairness set to fair-access
D. Voice-aware Layer 3 roaming
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?
A. the purchase of Universal APs that are the same modes as the current APs.
B. Aruba ClearPass to onboard the APs as campus APs in the new MC-based deployment
C. conversion of the existing Instant APs to campus APs (CAPs)
D. a Virtual Mobility Controller (VMC) which can be licensed to control Instant APs
A customer requires high availability for wireless services, including stateful failover for user connections if the Mobility Controller (MC) that handles the user traffic fails.
What is the requirement for the design?
A. MCs are deployed in a cluster, and they are on the same VLAN
B. MCs are distributed across each VLAN on which APs are deployed and have VRRP enabled.
C. MCs have a standby master IP address assigned to them.
D. MCs have enough licenses to support the APs for which they are active and standby MC.
What is one reason to recommend dedicated Air Monitors (AMs) for a customer, as opposed to APs that are doing WIPS in AP mode (hybrid)?
A. AMs can operate in a hybrid operation mode in which they can support clients, scan for threats, and contain detected threats.
B. AMs can implement wireless containment on any channel on which they detect a threat without negative impact on clients.
C. AMs can detect both 802.11 and non-802.11 sources of interference to the wireless network, while APs cannot.
D. AMs can maintain client and AP blacklists on their own without the need to communicate with a Mobility Controller (MC).
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. The MCs cannot provide any level of redundancy for each other unless one is moved into the other's subnet.
B. The MCs cannot be in a cluster, and they must use Virtual Router Redundancy Protocol (VRRP) to provide redundancy for each other.
C. The MCs can be in a cluster, but the cluster will not support features such as stateful failover.
D. Each MC can be the backup LMS for the other MCs' APs, but it cannot be in a cluster with the other MC.
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?
A. the packet loss
B. the throughput
C. the latency
D. the jitter
