Which guideline can the architect follow?
- A. Assign access layer switches IP addresses on a VLAN that is dedicated for switch management.
- B. Ensure that Telnet is enabled and set to listen on production VLANs.
- C. Ensure that DHCP is enabled on only the switch Default VLAN.
- D. Assign switches static IP addresses on the same VLAN on which APs are deployed.
Answer: A
NEW QUESTION # 21
Refer to the exhibit.
The exhibit shows the current plan for a wired network upgrade.
As much as possible, the customer wants to flatten the architecture and avoid recabling. However, each Building 2 switch must also maintain connectivity to the core if one link fails. What should the architect propose to meet the customer requirements?
- A. Use two additional 2930F switches to act as an aggregation layer for Building 2; connect them to the core on 40 GbE connections.
- B. Connect each Building 2 switch directly to the core on a single fiber strand through the use of SFP+-SR transceivers.
- C. Combine the switches in each Building 2 closet as a VSF fabric; establish two 10 GbE connections to the core per fabric.
- D. Extend additional fiber between the buildings so that each Building 2 switch can have a direct 10 GbE connection to the core.
Answer: C
NEW QUESTION # 22
Refer to the exhibit.
An architect needs to plan a network solution for a new office building with four floors. Each floor has two wiring closets with the equipment shown in the exhibit. The switches will connect to employee desktops, a few campus APs controlled by MCs, and printers. The switches do not implement tunneled node.
What is a best practice design for the VLANs and subnets for the wired devices?
- A. one VLAN per closet and a /25 subnet for each VLAN
- B. one VLAN for the entire building and a /23 subnet
- C. one VLAN per closet and a /24 subnet for each VLAN
- D. one VLAN per floor and a /24 subnet for each VLAN
Answer: C
Explanation:
The traditional guideline limits a wired VLAN to a /24 subnet, which provides enough IP addresses for 253 endpoints. You might have suggested one of three approaches: one VLAN per floor, one VLAN per building, or one VLAN per campus. The one VLAN per floor approach is not recommended because it interferes with roaming and adds complexity. If you did take this approach, the /24 subnets are not large enough for the requirements on every floor. You would need to ask for /23 subnets. The one VLAN per building approach would work if you considered each building its own RF domain. It provides roaming within a building and, if you are using a single cluster at the data center, between buildings. Ifyou deployed two MCs or clusters, one at each building, though, GRE tunneling would be required to support roaming between buildings.

For which scenario should an architect recommend Aruba Central Managed Portal (MSP)?
- A. for a service provider who needs to monitor multi-vendor environments
- B. for an enterprise with many branches that needs to manage services centrally
- C. for a service provider who needs to manage multiple customer networks
- D. for an enterprise that needs to manage data center services together with the network
Answer: C
Explanation:
Aruba Central Managed Portal (MSP) is a cloud-based network management platform that enables service providers to centrally manage and monitor multiple tenant accounts from a single interface1. MSP mode is a multi-tenant operational mode that Aruba Central accounts can be converted into, provided these accounts have subscribed to the Aruba Central app2. MSP mode allows service providers to provision and manage tenant accounts, assign devices to tenant accounts, manage subscription keys and perform other functions such as configuring network profiles and viewing alerts3. MSP mode is suitable for the scenario where a service provider needs to manage multiple customer networks, as it simplifies tenant network operations using capabilities such as zero-touch setup, historical data reporting, PCI compliance monitoring, and troubleshooting2.

- B. software version on Mobility Controllers (MCs)
- C. the OS used on wireless devices
- D. number of devices used
Answer: D
NEW QUESTION # 32
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 and DNS servers are carrier-grade and support a low transaction time.
- B. A third-party firewall integrates with ClearPass to filter the guest user traffic.
- C. DHCP servers can support a high number of scopes with a /24 size.
- D. A domain CA is set up to deploy certificates to a high volume of guest devices.
Answer: A
Explanation:
For a VHD wireless network at a large events venue, the architect should ensure that the DHCP and DNS servers are carrier-grade and support a low transaction time. This is because the DHCP and DNS servers are responsible for providing IP addresses and name resolution for the wireless devices, and they need to handle a high volume of requests and responses in a short time. A low transaction time reduces the latency and improves the user experience. A carrier-grade server is a server that meets the high standards of reliability, availability, and scalability required by telecom operators and service providers. A carrier-grade server can handle a large number of concurrent connections, provide redundancy and fault tolerance, and offer high performance and security.
Option A is incorrect because the DHCP server can support a high number of scopes with a /24 size, but this does not guarantee a low transaction time or a carrier-grade service. A scope is a range of IP addresses that the DHCP server can assign to the clients. A /24 size means that each scope can have up to 254 hosts. However, the number of scopes does not affect the speed or quality of the DHCP service. Option B is incorrect because a third-party firewall integrates with ClearPass to filter the guest user traffic, but this does not affect the DHCP and DNS services. A firewall is a device that monitors and controls the network traffic based on predefined rules. ClearPass is a network access control solution that provides secure authentication and policy enforcement. A firewall integration with ClearPass can enhance the security and visibility of the guest user traffic, but it does not improve the performance or reliability of the DHCP and DNS servers. Option C is incorrect because a domain CA is set up to deploy certificates to a high volume of guest devices, but this does not affect the DHCP and DNS services. A certificate authority (CA) is an entity that issues digital certificates that verify the identity and authenticity of the devices. A domain CA is a CA that is part of a domain and can issue certificates to the domain members. A certificate deployment is a process of distributing and installing the certificates to the devices. A certificate deployment can improve the security and trust of the wireless network, but it does not improve the speed or quality of the DHCP and DNS servers.

NEW QUESTION # 33
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. Airtime Fairness set to fair-access
- C. Voice-aware Layer 3 roaming
- D. Broadcast suppression combined with AirGroup
Answer: A
Explanation:
To ensure that wireless voice traffic is properly prioritized for Microsoft Skype for Business, the architect should set up firewall policies and SDN to mark voice on the MCs or MM. Firewall policies are used to classify and prioritize traffic based on the application, user role, device type, and location. SDN is used to integrate with the Skype for Business SDN API, which provides real-time information about voice and video sessions, such as source and destination IP addresses, ports, codecs, and quality metrics. By using firewall policies and SDN, the MCs or MM can dynamically mark voice traffic with the appropriate DSCP values and queue them in the highest priority queue on the wireless and wired network12.
The other options are not sufficient or relevant for ensuring wireless voice traffic prioritization for Skype for Business. Broadcast suppression combined with AirGroup is used to reduce the network overhead and improve the user experience for wireless devices that use multicast or broadcast protocols, such as Apple Bonjour or Microsoft UPnP3. Airtime Fairness set to fair-access is used to balance the airtime usage among clients with different capabilities and data rates, such as 802.11ac and 802.11n4. Voice-aware Layer 3 roaming is used to enable seamless handoff of voice sessions across different subnets without dropping the call5. While these features may enhance the overall wireless performance and reliability, they do not directly prioritize voice traffic for Skype for Business.

Answer: A
NEW QUESTION # 35
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. Each MC can be the backup LMS for the other MCs' APs, but it cannot be in a cluster with the other MC.
- D. The MCs can be in a cluster, but the cluster will not support features such as stateful failover.
Answer: C
Explanation:
According to the Aruba Validated Design: Campus Wireless LAN1, MCs that are in different subnets cannot form a cluster, which is a logical group of MCs that share the same configuration and provide redundancy and load balancing for each other. However, MCs that are in different subnets can still provide backup LMS (local mobility switch) functionality for each other's APs. This means that if the primary MC that controls an AP fails, the AP can fail over to the backup MC that is in a different subnet. However, this failover is not stateful, meaning that the user sessions and firewall states are not preserved. Therefore, option D is the correct answer.
Option A is incorrect because the MCs can provide some level of redundancy for each other without being in the same subnet, as explained above. Option B is incorrect because VRRP is not required to provide redundancy for MCs that are in different subnets. VRRP is a protocol that provides redundancy for routers by creating a virtual router with a shared IP address. However, MCs do not act as routers, and they do not need a shared IP address to provide backup LMS functionality. Option C is incorrect because the MCs cannot be in a cluster if they are in different subnets, as explained above. Therefore, the cluster will not support any features, such as stateful failover, load balancing, or centralized configuration. References: Aruba Validated Design:
