An administrator is configuring a public Azure Load Balancer. The administrator first deploys a Standard SKU public IP address named Pub-IP1.
The backend pool of the load balancer will contain two virtual machines, VM1 and VM2, which are deployed in a single Availability Set.
Which of the following configurations must be used to ensure the load balancer and its backend pool can be successfully deployed? (Select two.)
- A Standard SKU load balancerAnswer
- BA Basic SKU load balancer
- Virtual machine network interfaces (NICs) configured with Standard SKU public IP addresses or no instance-level public IP addressesAnswer
- DVirtual machine network interfaces (NICs) configured with Basic SKU public IP addresses
Answer
A Standard SKU load balancer and virtual machine network interfaces (NICs) configured with Standard SKU public IP addresses or no instance-level public IP addresses must be used.
To successfully deploy the solution, a Standard SKU load balancer must be used because the frontend public IP address is a Standard SKU. Additionally, the backend virtual machines' network interfaces must either have no instance-level public IP addresses or use Standard SKU public IP addresses to remain compatible with the Standard SKU load balancer.
Step-by-Step Solution
Key Concept
Azure Load Balancer SKU compatibility rules require matching SKUs between the load balancer, its frontend public IP addresses, and any instance-level public IP addresses on backend virtual machines.
