Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 210

An engineer must implement private VLANs for a group of Cisco UCS B-Series servers. The primary VLAN is present, but the secondary VLAN must be added to both fabrics. Which configuration set accomplishes this task?

Answer options

• A. UCS-A# scope eth-uplink - UCS-A /eth-uplink # create vlan vlan1981 1981 UCS-A /eth-uplink/vlan* # set sharing none
• B. UCS-A# scope eth-uplink - UCS-A /eth-uplink # create vlan vlan1981 1981 UCS-A /eth-uplink/vlan* # set sharing isolated
• C. UCS-A# scope eth-uplink - UCS-A /eth-uplink # scope fabric a UCS-A /eth-uplink/fabric # create vlan vlan1981 1981 UCS-A /eth-uplink/fabric/vlan* # set sharing secondary
• D. UCS-A# scope eth-uplink - UCS-A /eth-uplink # scope fabric a UCS-A /eth-uplink/fabric # create vlan vlan1981 1981 UCS-A /eth-uplink/fabric/vlan* # set sharing private

Correct answer: B

Explanation

The correct answer is B because it sets the VLAN sharing mode to 'isolated', which is necessary for a secondary VLAN in a private VLAN configuration. Option A incorrectly sets the sharing to 'none', while options C and D involve incorrect scopes and sharing modes that do not satisfy the requirement for a secondary VLAN.
