Question 1

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

A)  the packet loss 
B)  the throughput 
C)  the latency 
D)  the jitter

Question 2

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

A)  The DSCP values place both voice and video traffic in the video VMM queue, so voice does not receive the prioritization that is should. 
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)  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.

Question 3

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?

Accepted Answer

A)  two Aruba MCs on the same subnet that use VRRP without clustering 
B)  two Aruba MCs deployed as a Layer 3 cluster 
C)  two Aruba MCs on different subnets that use VRRP without clustering 
D)  two Aruba MCs deployed as a Layer 2 cluster

Accepted Answer

A)  MCs should be deployed centrally on the same VLAN to better meet these goals 
B)  MCs in a cluster must have additional AP licenses to support APs of a failed controller 
C)  The MC 7030 does not support enough APs for the requirements 
D)  The MC 7030 only supports clusters with up to three members

Accepted Answer

A)  The AP 335 and the AP 325 do not meet the customer requirements, so consider a different model. 
B)  The AP 325 meets the customer requirements, but the AP 335 does not. 
C)  Either the AP 335 or the AP 325 meet the customer requirements. 
D)  The AP 335 meets the customer requirements, but the AP 325 does not.

An architect needs to plan 802.11ac wireless deployment for an office environment with a mix of closed offices and cubicles. The coverage area is approximately 4,645 square meters (approximately 50,000 square feet) and has 350 users. The employees use the wireless network for typical office applications, such as email, Web, printing, and accessing shared files and datacenter services. The architect plans to do a predictive site survey and use VisualRF to plan the coverage. What is a general estimate for the AP count that the architect should have in mind?

Accepted Answer

A)  5-10 
B)  10-15 
C)  20-25

B)  for an enterprise that needs to manage data center services together with the network 
C)  for a service provider who needs to manage multiple customer networks 
D)  for an enterprise with many branches that needs to manage services centrally

Question 14

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 solution should the architect recommend on the 2930M switches to authenticate and control wired employee devices?

Accepted Answer

A)  MAC-Auth on edge ports and no tunneled node 
B)  802.1X on edge ports and per-user tunneled node 
C)  802.1X on edge ports and no tunneled node 
D)  Mac-Auth on edge ports and per-user tunneled node

Question 15

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

A)  60 Gbps 
B)  160 Gbps 
C)  200 Gbps 
D)  320 Gbps

Question 16

An architect proposes an Aruba solution with a hardware Mobility Master (MM) to a customer. The customer has a disaster recovery site which is connected to the main site at Layer 3. The customer requires the MM to remain available in case of a total site failure. Which plan meets the customer requirements?

Accepted Answer

A)  Deploy a hardware MM to the disaster recovery site and set up VRRP between them. 
B)  Deploy a hardware MM to the disaster recovery site and set its IP address as the standby master for MCs. 
C)  Deploy the virtual MM (VMM) to the disaster recovery site and set the VMM IP address to the same address as the hardware MM. 
D)  Deploy the virtual MM (VMM) to the disaster recovery site and configure clustering on the hardware and software appliances.

Question 17

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?

Accepted Answer

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

Question 18

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?

Accepted Answer

A)  An 802ac 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.
