To onboard a new UXI in an existing environment with 802.1X authentication, you need to use the UXI app on your smartphone and connect the UXI via Bluetooth. The UXI app allows you to scan the QR code on the UXI sensor and configure its network settings, such as SSID, password, IP address, etc. The Bluetooth connection allows you to communicate with the UXI sensor without requiring any network access or cellular connection. The other options are incorrect because they either do not use the UXI app or do not use Bluetooth. References:

The correct answer is B. sysops.

The sysops user role is a predefined role that allows users to perform system operations on the switch, such as backup, restore, upgrade, or reboot. The sysops user role also has access to the PUT and POST methods for REST API, which can be used to modify the switch configuration. The sysops user role has a privilege level of 15, which is the highest level of access on the switch1.

The other options are incorrect because:

• A. sysadmin: The sysadmin user role is a predefined role that allows users to view and modify the switch configuration using the CLI or the Web UI. The sysadmin user role does not have access to the REST API methods, and cannot perform firmware upgrades1.
• C. administrators: The administrators user role is a predefined role that has full access to all switch configuration information and all REST API methods. This role is more than what the Director of Security requires1.
• D. config: The config user role is a predefined role that allows users to view and modify the switch configuration using the CLI or the Web UI. The config user role does not have access to the REST API methods, and cannot perform firmware upgrades1.

Active gateway is a first hop redundancy protocol that eliminates a single point of failure. The active gateway feature is used to increase the availability of the default gateway servicing hosts on the same subnet. An active gateway improves the reliability and performance of the host network by enabling a virtual router to act as the default gateway for that network. If you have enabled active gateway, VRRP is not required3. Active gateway is similar to VRRP in that routed traffic from the VSX node is sourced from the switch interface MAC and not the virtual MAC address (VMAC). Each active gateway sends a periodic broadcast hello packet to avoid VMAC aging on the access switches. The switch views the active gateway IP as a self IP address3. Active gateway is preferable over VRRP because with VRRP traffic is still pushed over the ISL link, resulting in latency in the network3. Therefore, VRRP and active gateway are mutually exclusive on a VLAN, and answer A is correct.

Option A: MTU size must be increased beyond the default

This is because option A shows how to configure the MTU size for VXLAN tunnels on Aruba switches using the interface command and the vxlan command. The MTU size must be increased beyond the default value of 1500 bytes to accommodate the VXLAN header and payload2.

Therefore, option A is true regarding a VXLAN implementation on Aruba switches.

Option B: VNIs encapsulate and decapsulate VXLAN traffic

This is also true regarding a VXLAN implementation on Aruba switches. VNIs are used to encapsulate and decapsulate VXLAN traffic between two devices, such as a switch and a server. VNIs are also used to map VXLAN tunnels to overlay networks3.

Therefore, option B is also true regarding a VXLAN implementation on Aruba switches.

VXLAN is a Layer 2 encapsulation technology that substitutes the usage of VLAN numbers to label Ethernet broadcast domains with VXLAN numbers. VXLAN supports 224 Ethernet broadcast domains or VXLAN numbers. A VXLAN number ID is referred to as VNI. There is a one-to-one relationship between an Ethernet broadcast domain and a VNI. A single Ethernet broadcast domain can’t have more than one VNI.
