What is the ultimate goal of "compute" services according to the text?

• To solve real-world performance problems.

• To apply some kind of compute resource to a workload demand quickly and efficiently.

• To provide the cheapest solution for computing needs.

• To always use the same kind of compute resource for every problem.

What should you match the EC2 instance type to, as closely as possible?

• The cheapest available option.

• The most popular instance type.

• The workload you expect to face.

• The instance with the most storage.

What does ECU stand for in the context of EC2 instance parameters?

• Elastic Compute Unit.

• Elastic CPU Usage.

• Efficient Compute Utility.

What does the 'vCPUs' parameter represent for an EC2 instance?

• The velocity of the CPU.

• The virtualization capability of the CPU.

• The number of virtual CPUs allotted to an instance.

• The vendor of the CPU.

What does 'EBS-Optimized Available' indicate about an EC2 instance?

• It can be optimized for energy-saving purposes.

• It has additional security features enabled.

• It can be configured to use EBS optimization for dedicated I/O throughput.

• It is available for use with Elastic Beanstalk services.
