Selected Answer: B

n cloud environments like Azure, AWS, or GCP, traditional failover mechanisms like Gratuitous ARP or Router Discovery are often not supported or limited due to the virtualized nature of the infrastructure. Instead, CloudGuard clusters use API calls to the cloud provider to: Update routing tables Reassign public IPs Modify network interface associations This ensures that traffic is redirected to the new active cluster member during a failover.

Selected Answer: B

Neighbor discovery is specific to IPv6 and there is no ask for IPv6. The corr3ct answer is use of API to call to CSP using appropriate RBAC assigned by AAD.
