The correct answer is B. You need to specify the mgmt VRF at the end of the ping command. On HPE Aruba Networking CX switches, the out-of-band management interface uses the management VRF. If you issue a normal ping 10.1.50.11 command without specifying the management VRF, the switch attempts to send the ping using the default routing context rather than the out-of-band management interface. HPE Aruba Networking AOS-CX documentation for the ping command shows that the command supports the optional vrf < vrfname > parameter. The AOS-CX diagnostics documentation also specifically lists this as a cause of ping failure: the user intended to ping through the management VRF but forgot to add vrf mgmt to the command. The correct command would therefore be similar to ping 10.1.50.11 vrf mgmt. Option A is incorrect because the management interface can reach routed destinations if the management VRF has the proper route. Option C is incorrect because the management VRF already exists. Option D is incorrect because ping is supported.

The correct answer is A. Root bridge. In a switched infrastructure using Spanning Tree Protocol, the root bridge is the central reference point for calculating the loop-free Layer 2 topology. HPE Aruba Networking AOS-CX documentation explains that device roles, such as root bridge or leaf node, should be planned by adjusting spanning tree instance priority. It also notes that the placement of root bridges is important in a Layer 2 network domain because deterministic root and secondary root bridges provide predictability and protection. Switches calculate their best path toward the root bridge based on spanning tree information such as bridge priority, path cost, and port roles. This calculation determines which ports forward and which ports block to prevent loops. Option B is incorrect because a designated bridge or designated port forwards traffic for a segment but does not define the overall topology reference point. Option C is incorrect because “alternative bridge” is not the entity that defines best path selection. Option D is incorrect because “common bridge” is not the correct STP role.

The correct answer is B. Suitable for basic Layer 3 networks. HPE Aruba Networking AOS-CX IP Routing documentation describes static routing as a method that can be used when the network topology is simple enough. Static routes are manually configured routes that tell the switch how to reach specific destination networks or where to send default traffic. This makes static routing useful for smaller, stable, or basic Layer 3 environments where the number of routes is limited and the topology does not change frequently. Option A is incorrect because static routing is normally predictable; the administrator explicitly defines the path. Option C is incorrect because static routing does not scale well to large or complex networks, since every required route must be manually maintained. Option D is incorrect because static routing does not automatically adapt to network failures across the whole network like a dynamic routing protocol can. Therefore, static routing is best described as suitable for basic Layer 3 networks.
