A network engineer wants to ensure Layer 2 isolation of customer traffic using a private VLAN. Which configuration must be made before the private VLAN is configured?
| A. |
Disable VTP and manually assign VLANs. | |
| B. |
Ensure all switches are configured as VTP server mode. | |
| C. |
Configure VTP Transparent Mode. | |
| D. |
Enable VTP version 3. |
You must configure VTP to transparent mode before you can create a private VLAN. Private VLANs are configured in the context of a single switch and cannot have members on other switches. Private VLANs also carry TLVs that are not known to all types of Cisco switches.
