   A company is deploying a pair of BIG-IP VE instances in AWS for high availability. The instances must share the same configuration and fail over automatically if one instance becomes unhealthy. The application uses a floating IP address that clients connect to. Which combination of AWS services and BIG-IP features should be used?

   • AUse an AWS Network Load Balancer (NLB) in front of both BIG-IP VE instances, and configure the BIG-IPs in an active-standby cluster with a floating IP.
   • BAssign an Elastic IP to the primary BIG-IP VE and use a script to reassign it to the secondary instance on failure.
   • CUse an AWS Application Load Balancer (ALB) in front of both BIG-IP VE instances, and configure the BIG-IPs independently without clustering.
   • DUse an AWS Global Accelerator to route traffic to both BIG-IP VE instances, and configure the BIG-IPs in an active-active cluster.

   An organization is deploying BIG-IP VE in Azure to load-balance a mission-critical application that handles 50,000 SSL transactions per second (TPS). The application team expects the traffic to double during peak season. The deployment must use a single BIG-IP VE instance initially but must be able to scale out without re-architecting. Which instance type and licensing model should the engineer choose?

   • AA GPU-accelerated N-series VM with a per-hour PAYG license, sized for the current 50,000 TPS, and plan to add a second instance manually during peak season.
   • BA memory-optimized E-series VM with a per-hour BYOL license, sized for the current 50,000 TPS, and rely on Azure Load Balancer to distribute traffic to multiple instances.
   • CA high-CPU F-series VM with a per-hour PAYG license, sized for the peak 100,000 TPS, and configure an Azure autoscaling rule based on CPU utilization.
   • DA standard D-series VM with a per-hour BYOL license, sized for the current 50,000 TPS, and plan to manually resize the VM when traffic doubles.

   What is the purpose of a key pair when deploying an F5 BIG-IP instance?

   • ATo encrypt the instance's boot volume
   • BTo authenticate the instance to the cloud API
   • CTo license the BIG-IP software
