A company wants to push VPC Flow Logs to an Amazon S3 bucket. A company wants to optimize long-term compute costs of AWS Lambda functions and Amazon EC2 instances. Which AWS purchasing option should the company choose to meet these requirements?

Accepted Answer

Compute Savings Plans are a flexible and cost-effective way to optimize long-term compute costs of AWS Lambda functions and Amazon EC2 instances. With Compute Savings Plans, customers can commit to a consistent amount of compute usage (measured in $/hour) for a 1-year or 3-year term and receive a disco of up to 66% compared to On-Demand prices3. Dedicated Hosts are physical servers with EC2 instance capacity fully dedicated to the customer's use. They suitable for customers who have specific server-bound software licenses or compliance requirements4. Reserved Instances are a pricing model that provide significant discount (up to 75%) compared to On-Demand pricing and a capacity reservation for EC2 instances. They are available in 1-year or 3-year term different payment options5. Spot Instances are spare EC2 instances that are available at up to 90% discount compared to On-Demand prices. They are suita for customers who have flexible start and end times, can withstand interruptions, and can handle excess capacity.

Question 7

- (Topic 2)

A company wants to use Amazon EC2 instances for a stable production workload that will run for 1 year.

Which instance purchasing option meets these requirements MOST cost-effectively?

Accepted Answer

B is correct because Reserved Instances are the instance purchasing option that offers the most cost-effective way to use Amazon EC2 instances for a st production workload that will run for 1 year, as they provide significant discounts compared to On-Demand Instances in exchange for a commitment to use specific amount of computing power for a period of time. A is incorrect because Dedicated Hosts are the instance purchasing option that allows customers physical servers that are fully dedicated to their use, which is more expensive and less flexible than Reserved Instances. C is incorrect because On-Dem Instances are the instance purchasing option that allows customers to pay for compute capacity by the hour or second with no long-term commitments, whic more suitable for short-term, variable, and unpredictable workloads. D is incorrect because Spot Instances are the instance purchasing option that allow customers to bid on spare Amazon EC2 computing capacity, which is more suitable for flexible, scalable, and fault-tolerant workloads that can tolerate interruptions.

Which AWS Cloud design principle does a company follow by using AWS CloudTrail?

Accepted Answer

The company follows the AWS Cloud design principle of ensuring traceability by using AWS CloudTrail. AWS CloudTrail is a service that records the API c events made by or on behalf of the AWS account. The company can use AWS CloudTrail to monitor, audit, and analyze the activity and changes in their AWS resources and applications. AWS CloudTrail helps the company to achieve compliance, security, governance, and operational efficiency. Recovering automatically, performing operations as code, and measuring efficiency are other AWS Cloud design principles, but they are not directly related to using CloudTrail. Recovering automatically means that the company can design their cloud workloads to handle failures gracefully and resume normal operations manual intervention. Performing operations as code means that the company can automate the creation, configuration, and management of their cloud resour

using scripts or templates. Measuring efficiency means that the company can monitor and optimize the performance and utilization of their cloud resource applications34

Which of the following are design principles for reliability in the AWS Cloud? (Select TWO.)

Accepted Answer

The design principles for reliability in the AWS Cloud are:

- ? Test recovery procedures. The best way to ensure that systems can recover from failures is to regularly test them using simulated scenarios. This can identify gaps and improve the recovery process.
- ? Automatically recover from failure. By using automation, systems can detect and correct failures without human intervention. This can reduce the impac duration of failures and improve the availability of the system.
- ? Scale horizontally to increase aggregate system availability. By adding more redundant resources to the system, the impact of individual resource fail reduced. This can also improve the performance and scalability of the system.
- ? Stop guessing capacity. By using monitoring and automation, systems can adjust the capacity based on the demand and performance metrics. This can prev failures due to insufficient or excessive capacity and optimize the cost and efficiency of the system.
- ? Manage change in automation. By using automation, changes to the system can be applied in a consistent and controlled manner. This can reduce the risk human errors and configuration drifts that can cause failures. AWS Well- Architected Framework
