   An administrator is configuring VLANs on an ECS node. The switch port connected to the node is configured as an access port for VLAN 100. The administrator creates a VLAN subinterface on eth0 for VLAN 200 and assigns an IP address. Which statement is true?

   • AThe node will communicate on VLAN 100 only, and the subinterface for VLAN 200 will be ignored.
   • BThe node will be able to communicate on VLAN 200 because the subinterface handles the tagging.
   • CThe node will not be able to communicate on VLAN 200 because the switch port is not configured as a trunk port.
   • DThe node will be able to communicate on both VLAN 100 and VLAN 200 because the subinterface overrides the access port configuration.

   A company is deploying a three-node ECS cluster. The network team has allocated three separate VLANs: one for management, one for storage, and one for client traffic. During the core OS installation, the administrator needs to ensure that the storage network traffic remains isolated from the client network. Which configuration step is essential to achieve this requirement?

   • ADisable VLAN tagging on all interfaces and rely on the physical switch to segregate traffic.
   • BConfigure all NICs with the same VLAN ID to simplify management and reduce configuration errors.
   • CAssign a separate VLAN ID to each physical NIC and configure the corresponding interfaces during the ECS core OS installation.
   • DAssign IP addresses from the same subnet to all interfaces to ensure connectivity.
