Refer to the exhibit. The EPG-100 must be extended to the vCenter as a port group with a tagged VLAN ID of 100. Which set of actions accomplishes this goal?

The correct answer is C. Define a dynamic VLAN range (from 100-200) under a VLAN pool that is associated with the del. To extend an EPG to vCenter as a port group, a dynamic VLAN range within a VLAN pool must be defined and associated with a Virtual Machine Manager (VMM) domain.

Why each option

To extend an EPG to vCenter as a port group, a dynamic VLAN range within a VLAN pool must be defined and associated with a Virtual Machine Manager (VMM) domain.

ADefine a static VLAN range (from 100-200) under a VLAN pool that is associated with the

Static VLAN ranges are typically used for physical domains (bare-metal servers) or L2Outs, not for automated VMM domain integration.

BDefine a static VLAN range (from 100-200) under a VLAN pool that is associated with the

Static VLAN ranges are typically used for physical domains or L2Outs, not for automated VMM domain integration, where ACI dynamically assigns VLANs.

CDefine a dynamic VLAN range (from 100-200) under a VLAN pool that is associated with the delCorrect

For ACI to automatically create and manage port groups in vCenter for an EPG, it requires a VMM domain with a dynamic VLAN pool. ACI then dynamically allocates VLAN IDs from this pool to the port groups it provisions in vCenter, extending the EPG's network to the virtual environment.

DDefine a dynamic VLAN range (from 100-200) under a VLAN pool that is associated with the

While a dynamic VLAN range is required for VMM integration, if it were associated with a Physical Domain instead of a VMM Domain, ACI would not be able to push port group configurations to vCenter.
