These are the correct statements about access from the servers to the Core when the ISL link between the switches fails, but the keepalive interface functions. Server 1 can access the core layer via both uplinks because it is connected to VSX-A, which is still active for VLAN 10. Server 2 can also access the core layer via its uplink to VSX-B, which is still active for VLAN 10 because of Active Gateway feature. Server 1 and Server 2 can communicate with each other via the core layer because they are in the same VLAN and subnet, and their traffic can be routed through the core switches. The other statements are incorrect because they either describe scenarios thatare not possible or not relevant to the question.References: https://www.arubanetworks.com/techdocs/AOS-CX/10.04/HTML/5200-6728/bk01-

An inbound ACL is applied to traffic entering a port or VLAN. An outbound ACL is applied to traffic leaving a port or VLAN4. To deny ping sourcing from the user VLAN to the IT management VLAN, an inbound ACL on the user VLAN should be used to filter icmp echo traffic toward the IT management VLAN. Icmp echo-reply traffic is not needed to be allowed because it is already permitted by default5.

Authentication survivability is a feature that allows the device to remain operational when a remote link failure occurs between a Gateway cluster and a RADIUS server that is either in the cloud or a datacenter. Authentication survivability enables the Gateway cluster to cache successful authentication requests from the RADIUS server and use them to authenticate clients when the RADIUS server is unreachable. Authentication survivability also allows clients to use MAC caching or MAC authentication bypass (MAB) methods to access the network when the RADIUS server is down.References:https://www.arubanetworks.com/assets/tg/TG_AuthSurvivability.pdf

a) A device with IP address 10.1.3.7 in a network wants to send the traffic stream to a device with IP address 10.13.4.2 in the other network -> Unicast 

b) One/more senders and one/more recipients participate in data transfer traffic -> Multicast 

c) Sent to all hosts on a remote network -> IP Directed Broadcast 

d) Sent to all NICs on the same network segment as the source NIC -> Broadcast

The terms broadcast, IP directed broadcast, multicast, and unicast are different types of communication or data transmission over a network. They differ in how many devices are involved in the communication and how they address the messages. The following table summarizes the characteristics of each term1:

The correct answer is A. DMO is configured individually for each SSID in use in the network.

DMO is a feature that allows the AP to convert multicast streams into unicast streams over the wireless link. This enhances the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients. DMO is configured individually for each SSID in use in the network, as different SSIDs may have different multicast requirements.

According to the Aruba documentConfiguring WLAN Settings for an SSID Profile, one of the steps to configure DMO is:

Dynamic multicast optimization: Select Enabled to allow IAP to convert multicast streams into unicast streams over the wireless link. Enabling Dynamic Multicast Optimization (DMO) enhances the quality and reliability of streaming video, while preserving the bandwidth available to the non-video clients.

The other options are incorrect because:

B. The AP does not use QoS to provide equal air time for multicast traffic. QoS is a feature that prioritizes different types of traffic based on their importance and latency sensitivity. QoS does not affect how multicast streams are transmitted over the wireless link.

C. DMO is not configured globally for each SSID in use in the network. DMO is configured individually for each SSID, as different SSIDs may have different multicast requirements.

D. The controller does not convert multicast streams into unicast streams. The AP does the conversion, as it is closer to the wireless clients and can optimize the transmission based on the client capabilities and channel conditions.

Wi-Fi 6 is an industry certification for products that support the new wireless standard 802.11ax, also known as “high-efficiency wireless”. Wi-Fi 6 offers increased capacities, improved resource utilization and higher throughput speeds than previous standards.

Option B: ClientMatch

This is because option B shows how to use ClientMatch to optimize the wireless performance of Wi-Fi 6 clients on a UniFi network. ClientMatch is a feature that uses machine learning to analyze the traffic patterns of each client and assign them to the best available AP based on their location, device type, and network conditions2.

Therefore, option B is the best technology to implement for your customer’s issue.

These are the correct requirements to ensure that WMM (Wi-Fi Multimedia) is working effectively. WMM is a standard that provides quality of service (QoS) for wireless networks by prioritizing traffic into four categories: voice, video, best effort, and background. To use WMM, both the APs and the controller must be Wi-Fi CERTIFIED for WMM, which means they have passed interoperability tests and comply with the standard. WMM must also be enabled on the APs and the controller, which is usually the default setting. The client device must also be Wi-Fi CERTIFIED for WMM and configured for WMM marking, which means it can tag its traffic with the appropriate priority level based on the application type. The other options are incorrect because they are either not related to WMM or not required for WMM to work.

The statements that are true regarding Aruba NAE agents are A and C.

A. A single NAE script can be used by multiple NAE agents. This means that you can create different instances of the same script with different parameters or settings.For example, you can use the same script to monitor different VLANs or interfaces on the switch1.

C. NAE agents will never consume more than 10% of switch processor resources. This is a built-in safeguard that prevents the agents from affecting the switch performance or stability.If an agent exceeds the 10% limit, it will be automatically disabled and an alert will be generated2.

The other options are incorrect because:

B. NAE agents are not active at all times. They can be enabled or disabled by the user, either manually or based on a schedule.They can also be disabled automatically if they encounter an error or exceed the resource limit1.

D. NAE scripts do not need to be reviewed and signed by Aruba before being used. You can create your own custom scripts using Python and upload them to the switch or Aruba Central.You can also use the scripts provided by Aruba or other sources, as long as they are compatible with the switch firmware version1.

E. A single NAE agent cannot be used by multiple NAE scripts. An agent is an instance of a script that runs on the switch.Each agent can only run one script at a time1.

This is because option C shows how to create a single group in Central with different configuration methods defined for each device type. For example, you can create a group with the name Group1, and within this group, you can enable template-based configuration method for switches and UI-based configuration method for Instant APs and Gateways. Aruba Central identifies both these groups under a single name (Group1). If a device type in the group is marked for template-based configuration method, the group name is prefixed with TG (TG Group1). You can use Group1 as the group ID for workflows such as user management, monitoring, reports, and audit trail2.

The persona role option that should be selected to deploy a Gateway and take advantage of all the SD-WAN features is A. ArubaOS 10 Branch.

ArubaOS 10 Branch is a persona that enables the Gateway to provide both LAN and WAN functionality for branch networks. The Gateway can act as a wireless controller, a router, a firewall, and an SD-WAN device.The SD-WAN features include route andtunnel orchestration, dynamic path steering, forward error correction, SaaS traffic optimization, SASE orchestration, and more1.

The other options are incorrect because:

B. ArubaOS 10 VPN Concentrator: This is a persona that enables the Gateway to act as a VPN concentrator for remote access or site-to-site VPN connections.It does not provide SD-WAN features2.

C. ArubaOS 10 Wireless: This is a persona that enables the Gateway to act as a wireless controller for campus networks.It does not provide SD-WAN features3.

D. ArubaOS 10 Mobility: This is a persona that enables the Gateway to act as a mobility controller for campus networks. It does not provide SD-WAN features.
