You have been asked to segment the network for an R&D workgroup. The requirement is to allow the R&D group access to the existing servers, but no other VLANs should be able to access R&D. How can this be achieved with maximum flexibility?

A. Create a new VLAN, configure a routed SVI interface, and apply ACLs to the VLAN interfaces.
B. Create a new VLAN, configure a routed SVI interface, and apply ACLs to the R&D ports.
C. Create a new VLAN, and install a new R&D server in the new VLAN.
D. Create a new VLAN, and trunk the existing file server for both the production and R&D network.

A. Creating the new VLAN will logically segment this work group. Creating a Switched Virtual Interface (SVI) will allow routing on the layer 3 switch. The ACLs should only be applied to VLAN interfaces. Although the other solutions achieve a similar goal, they do not provide flexibility.
