Amazon CLF-C02 Online Questions & Answers

• Question 1081:

  What is a benefit of using an Elastic Load Balancing (ELB) load balancer with applications running in the AWS Cloud?

  A. An ELB will automatically scale resources to meet capacity needs.
  B. An ELB can balance traffic across multiple compute resources.
  C. An ELB can span multiple AWS Regions.
  D. An ELB can balance traffic between multiple internet gateways.
  B. An ELB can balance traffic across multiple compute resources.

  ---

  Explanation

  Elastic Load Balancing (ELB) distributes incoming traffic across multiple targets, such as EC2 instances, containers, and IP addresses, ensuring better application availability and fault tolerance. While ELB scales to meet traffic demands, it does not inherently scale compute resources themselves, span multiple regions, or balance traffic between internet gateways.

• Question 1083:

  What is the recommended use case for Amazon EC2 On-Demand Instances?

  A. A steady-state workload that requires a particular EC2 instance configuration for a long period of time.
  B. A workload that can be interrupted for a project that requires the lowest possible cost.
  C. An unpredictable workload that does not require a long-term commitment.
  D. A workload that is expected to run for longer than 1 year.
  C. An unpredictable workload that does not require a long-term commitment.

  ---

  Explanation

  Amazon EC2 On-Demand Instances are ideal for unpredictable workloads that do not require a long-term commitment. This option allows users to pay for compute capacity by the hour or second, with no long-term commitments. It is suitable for short-term, spiky, or unpredictable workloads that cannot be interrupted and require flexibility.

  Option A is better suited for Reserved Instances, Option B is ideal for Spot Instances, and Option D is more suited for Reserved Instances due to cost optimization for long-term use.

  "There is no long-term commitment required when you purchase On-Demand Instances. You pay only for the seconds that your On-Demand Instances are in the running state, with a 60-second minimum. The price per second for a running On-Demand Instance is fixed and is listed on the Amazon EC2 Pricing, On-Demand Pricing page. We recommend that you use On-Demand Instances for applications with short-term, irregular workloads that cannot be interrupted." Source: AWS Documentation - Amazon EC2 On-Demand Instances
