A. B. C. D.A
VRRP-A (Virtual Router Redundancy Protocol Advanced) is a protocol used to provide redundancy for IP addresses, with multiple devices sharing the same virtual IP address (VIP). When VRRP-A is enabled on a device with multiple partitions, each partition has its own independent routing table and configuration, and VRID 0 is the default VRID (Virtual Router ID) assigned to the shared partition.
VRID 0 is used to identify the default gateway for the network, and it is assigned to the VRRP-A router that has the highest priority among the routers in the VRRP group. When VRRP-A is enabled on a device with multiple partitions, VRID 0 is initially enabled only in the shared partition. Partition administrators can choose to enable VRID 0 in their respective partitions, but it is not mandatory.
Option A, "Each partition has its own distinct VRID 0," is incorrect because VRID 0 is only assigned to the shared partition, and it is not possible to assign the same VRID to multiple partitions.
Option B, "VRID 0 only exists in the shared partition; private partitions can only contain VRIDs numbered higher than 0," is partly correct. VRID 0 is initially enabled only in the shared partition, and private partitions can have VRIDs numbered higher than 0. However, VRID 0 can also be enabled in private partitions by the partition administrators.
Option C, "VRID 0 is initially enabled only in the shared partition; partition administrators can enable VRID 0 in their partitions," is the correct answer. VRID 0 is assigned to the shared partition by default, and partition administrators can choose to enable it in their respective partitions if needed.
Option D, "When using VRRP-A on a device with multiple partitions, VRID 0 is automatically disabled," is incorrect because VRID 0 is enabled by default in the shared partition, and it can also be enabled in private partitions by the partition administrators.
In conclusion, when VRRP-A is enabled on a device with multiple partitions, VRID 0 is initially enabled only in the shared partition, and partition administrators can choose to enable it in their respective partitions if needed.
