Correct answer: interface 1/1/1 port-security enable port-security mac-address sticky port-security client-limit 1 port-security violation-mode shutdown-notify

This configuration correctly meets all requirements. `port-security enable` activates the feature. `mac-address sticky` learns the first MAC address and binds it to the port. `client-limit 1` enforces the single device policy. `violation-mode shutdown-notify` is the correct syntax in AOS-CX to both disable the port (`shutdown`) and send an SNMP trap (`notify`) upon violation.

Correct answer: show vsf

The `show vsf` command is specifically designed to display the status of the Virtual Switching Framework (VSF). It provides a summary table that includes each member's ID, MAC address, state (e.g., Commander, Standby, Member), priority, and model, which is exactly the information required.

Correct answers: The `ip routing` command enabled globally; Configured Switched Virtual Interfaces (SVIs) for each VLAN with an IP address

This global command enables Layer 3 routing capabilities on the switch. Without it, the switch operates only at Layer 2 and cannot route between VLANs.

Each VLAN that needs to participate in routing requires a Layer 3 interface, which is an SVI (e.g., `interface vlan 10`). This SVI must be configured with an IP address from its respective subnet to act as the default gateway for devices in that VLAN.

Correct answer: False

This statement is false. If the TFTP server is on the same IP subnet as one of the switch's IP interfaces (like the management VRF), the switch can use ARP to find the server's MAC address directly and does not need a default gateway. A default gateway is only required when the destination IP address is on a different subnet.

Correct answer: Classification

Classification is the first step in any QoS policy. It is the process of identifying and categorizing traffic based on its characteristics, such as source/destination IP, port numbers, or, in this case, the existing DSCP value. Once classified, the traffic can then be subjected to other QoS actions like marking, queuing, and scheduling.

Correct answer: configuration session timeout 10

The `configuration session timeout ` command starts a timed session. If the administrator does not enter the `configuration session confirm` command within the specified timeout period (10 minutes in this case), the switch automatically discards all changes made during the session and reverts to the configuration that existed before the session started. This is a critical safety feature for remote management.

Correct answer: A mismatched SFP/SFP+ transceiver pair

For a fiber link to come up, the transceivers (SFP/SFP+) at both ends must be compatible. Common mismatches include using a multi-mode (SR) transceiver on one end and a single-mode (LR) transceiver on the other, or using different wavelength transceivers. This would prevent the optical link from establishing, resulting in a 'down' port status. VLAN mismatches or STP issues occur at Layer 2 and would not typically cause the physical link to be down.

Correct answer: NetEdit

Aruba NetEdit is specifically designed for intelligent network automation and orchestration. Its key features include centralized configuration, validation of changes before deployment, conformance checks against a baseline, and detection of configuration drift, making it the correct tool for these tasks.

Correct answer: To map a known IP address to an unknown MAC address on the local network segment.

ARP operates at the boundary of Layer 2 and Layer 3. When a device needs to send a packet to another device on the same local network, it knows the destination IP address but needs the destination MAC address to build the Layer 2 Ethernet frame. ARP is the protocol used to broadcast a request (`Who has IP address X?`) and receive a reply (`I have IP address X, my MAC address is Y.`)

Correct answer: interface 1/1/24 vlan trunk native 10 vlan trunk allowed 10,20,30

This is the correct command sequence. `vlan trunk native 10` specifies that frames belonging to VLAN 10 will be sent untagged across this link. `vlan trunk allowed 10,20,30` explicitly permits traffic for all three required VLANs. It is important to include the native VLAN in the allowed list as well.
