The capability that enables plug-and-play provisioning of access points in an HPE Aruba network is the UCC Service. The UCC Service is a cloud-based service that allows the access points to automatically discover and connect to the Aruba Central management platform without any manual intervention. The UCC Service also provides zero-touch configuration, firmware updates, and monitoring for the access points1.

The other options are incorrect because:

B) LLDP-MED: LLDP-MED is a protocol that enhances the interoperability between network devices and IP phones. It does not enable plug-and-play provisioning of access points2.

C) SRTP: SRTP is a protocol that provides encryption and authentication for voice and video traffic. It does not enable plug-and-play provisioning of access points3.

D) CSMA: CSMA is a protocol that regulates how devices share a common medium, such as a wireless channel. It does not enable plug-and-play provisioning of access points.

The standard that is supported by some Aruba APs and can enable a customer to accurately locate wireless client devices within a few meters is

A) 802.11mc.

802.11mc is an IEEE standard that enables computing devices to measure the distance to nearby Wi-Fi access points using a technique called Fine Timing Measurement (FTM). FTM uses precise timestamps to calculate the round-trip time of Wi-Fi frames between the device and the access point, and then converts it to a distance estimate. By using multiple access points and triangulation methods, the device can determine its location with high accuracy1.

According to the Aruba document 802.11mc Support, this feature is supported on 500 Series, 510 Series, 530 Series, 550 Series, 560 Series and 570 Series access points. These APs act as FTM responders to time measurement queries sent from a client. To configure the AP to send FTM responses, you need to enable the ftm-responder-enable parameter in the WLAN SSID profile1.

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 and tunnel 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.

The correct action to fix the issue is C. Change the SSID to WPA3-Enhanced Open.

WPA3-OWE is not a valid SSID type in Central. OWE stands for Opportunistic Wireless Encryption, and it is a feature that provides encryption for open networks without requiring authentication. OWE is also known as Enhanced Open, and it is one of the options for WPA3 SSIDs in Central1.

According to the Aruba document Configuring WLAN Settings for an SSID Profile, one of the steps to configure a WPA3 SSID is:

Select the Security Level from the drop-down list. The following options are available:

WPA3-Personal: This option uses Simultaneous Authentication of Equals (SAE) to provide stronger password-based authentication and key exchange than WPA2-Personal.

WPA3-Enterprise: This option uses 192-bit cryptographic strength for authentication and encryption, as defined by the Commercial National Security Algorithm (CNSA) suite.

WPA3-Enterprise (CCM): This option uses 128-bit cryptographic strength for authentication and encryption, as defined by the Counter with CBC-MAC (CCM) mode.

WPA3-Enhanced Open: This option uses Opportunistic Wireless Encryption (OWE) to provide encryption for open networks without requiring authentication.

The other options are incorrect because:

A) WPA3-Enterprise (CNSA) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.

B) WPA3-Personal is a valid SSID type, but it requires a passphrase to join the network, which may not be suitable for the company's use case.

D) WPA3-Enterprise (CCM) is a valid SSID type, but it requires 802.1X authentication with a RADIUS server, which may not be suitable for the company's use case.

This is because Best Effort traffic is all other kinds of non-detrimental traffic that are not sensitive to Quality of Service metrics (jitter, packet loss, latency).A typical example would be peer-to-peer and email applications2.Background traffic is a type of traffic that is used for system maintenance or backup purposes and does not affect the performance or availability of the network3.

Therefore, Best Effort traffic has a higher priority than Background traffic in terms of network resources allocation and management.

According to the Aruba Documentation Portal1, the Aruba CX 6200F VSF stack is a feature that allows you to create a virtual switching framework (VSF) with up to eight members that can be managed as a single logical device. The VSF stack provides benefits such as load balancing, failover, redundancy, and security.

To add a new device to the VSF stack, you need to configure the device with the VSF commandvsf memberand specify the type, link, and secondary-member information. The type of the new device can be one of the following:JL726A,JL726B,JL726C, orJL726D. The link is the interface that connects the new device to the existing VSF members. The secondary-member is an optional parameter that specifies which member will act as a backup in case of a failure.

According to the Aruba Documentation Portal1, the ArubaOS-CX switch supports various features to control the ingress traffic on specific ports, such as rate limiting, QoS shaping, and access control. These features can help reduce the impact of excessive broadcast traffic on the network performance and availability.

This is because rate limiting is a feature that allows you to limit the inbound or outbound traffic on a port based on a percentage of the port capacity or a fixed amount of bytes per second.Rate limiting can help prevent broadcast storms by reducing the amount of broadcast packets that enter or leave a port
