An administrator is configuring a high-availability backend pool for a Standard SKU Azure Load Balancer. The backend pool contains several Azure Virtual Machines, but each virtual machine currently has a Basic SKU public IP address associated with its network interface. During deployment, the administrator encounters a validation failure. Which of the following configuration changes can resolve this validation mismatch? (Select two.)
- Upgrade the public IP addresses of the virtual machines to the Standard SKU.Cevap
- Remove the Basic SKU public IP addresses from the network interfaces of the virtual machines.Cevap
- CAssociate the existing Basic SKU public IP addresses with a Standard SKU Azure NAT Gateway.
- DCreate a Network Security Group rule to permit inbound traffic from the AzureLoadBalancer service tag.
Cevap
To resolve the validation failure, you must either upgrade the virtual machines' public IP addresses to the Standard SKU or remove the Basic SKU public IP addresses from their network interfaces entirely.
The Standard Azure Load Balancer requires that all virtual machines in its backend pool use Standard SKU public IP addresses or have no public IP addresses assigned at all. Therefore, upgrading the virtual machines' public IPs to the Standard SKU or removing the Basic SKU public IPs entirely satisfies the SKU alignment constraints and resolves the validation failure.
