Which two options are two functions of the data center access layer? (Choose two.)

High data transfer rate is an overall network design requirement and goal, not a specific function unique to the access layer, which primarily focuses on connectivity.

Packet filtering can occur at various network layers, often more comprehensively at the aggregation or core layers, and is not a primary defining function of the access layer itself.

The access layer in a data center network is specifically designed to provide direct connectivity for end devices, most notably servers, attaching them to the network infrastructure.

QoS policy enforcement is applied across different network layers to manage traffic prioritization, and while present at the access layer, it is not a function unique to it.

High network fault tolerance is an architectural goal for the entire data center network, not a specific function performed solely by the access layer itself.

VLAN creation, or more precisely the assignment of access layer ports to specific VLANs, is a critical function performed at this layer to segment network traffic and isolate different groups of devices or applications.
