D.

Suggested answer: C

Explanation:

The network configuration shown for a Dell EMC PowerStore T node A management port indicates that VLAN 1 is set as the access VLAN, which means it will pass untagged traffic. The port is also configured as a trunk port, which allows it to pass traffic from multiple VLANs, but only VLAN 1501 is specified in the allowed list, meaning it will pass as tagged traffic. This configuration is typical for network interfaces on storage systems where management traffic is separated from other types of traffic for security and performance reasons.

In detail, the configuration commands are:

switchport access vlan 1: Sets VLAN 1 as the access VLAN, which passes untagged traffic.

switchport mode trunk: Enables trunking on the port, allowing it to pass traffic from multiple VLANs.

switchport trunk allowed vlan 1501: Specifies that only VLAN 1501 traffic is allowed on the trunk and will be tagged.
