During private cloud network planning, which consideration is necessary to support vNICs operating in bridging mode?

• A. Ensure enough IP addresses for networks and subnets
• B. Configure VPN gateways
• C. Allocate VLAN IDs
• D. Set up firewall rules

Answer: (A)

Bridging mode brings virtual NICs onto the same Layer 2 network as the physical infrastructure, so every bridged vNIC must have an IP address within a valid subnet on that network. Planning and provisioning enough IP address space for the networks and subnets used by these bridged vNICs is essential; without it, you can’t assign addresses, leading to communication failures and IP conflicts as you scale.

Other options aren’t inherently about enabling bridging: VPN gateways are for remote access or site-to-site connections, VLAN IDs are useful for segmentation but not strictly required to support bridged vNICs, and firewall rules relate to security boundaries rather than the fundamental connectivity of bridged interfaces.
