b) Inbound data transfer
c) EBS snapshots
d) Outbound data transfer
Answer is: b – Inbound data transfer
Explanation: When migrating workloads to the AWS Cloud, it’s important to consider the associated costs. In this case, inbound data transfer to the AWS Cloud is not subject to any additional charges. However, other elements such as RDS database backups, EBS snapshots, and outbound data transfer may incur costs based on the usage and storage requirements.
Question 58 A large e-commerce company is preparing to launch a new online shopping platform that expects high traffic volumes. They plan to deploy multiple instances of their application on Amazon EC2. Which of the following strategies can help minimize operational expenses?
a) Implementing Auto Scaling for the EC2 instances to dynamically adjust capacity based on demand.
b) Deploying the EC2 instances across multiple Availability Zones (AZs) for improved fault tolerance and redundancy.
c) Utilizing instance store-backed Amazon Machine Images (AMIs) for faster instance performance and cost optimization.
d) Employing Cluster placement groups to enhance network performance and achieve higher application throughput.
Answer is: a – Implementing Auto Scaling for the EC2 instances to dynamically adjust capacity based on demand.
Explanation: To reduce operational expenses when deploying a high-volume application on multiple Amazon EC2 instances, it is recommended to utilize Auto Scaling capabilities. Auto Scaling enables automatic scaling of EC2 instances based on predefined conditions, ensuring that the application can handle varying levels of demand while optimizing costs by only running the required number of instances at any given time.
Question 59 As an AWS Architect, you are tasked with designing a hosting solution for an application using EC2 instances. The infrastructure needs to scale on-demand and be fault-tolerant. Which of the following components would you include in the design? (Select TWO)
a) AWS Auto Scaling
b) Amazon GuardDuty
c) Elastic Load Balancing
d) Amazon CloudWatch
Answer is: (a) AWS Auto Scaling, and (c) Elastic Load Balancing
Explanation: To meet the requirements of a scalable and fault-tolerant hosting solution for the application, two components that should be included in the design are AWS Auto Scaling and Elastic Load Balancing. AWS Auto Scaling enables the automatic scaling of EC2 instances based on predefined conditions, allowing the infrastructure to scale up or down as demand fluctuates. Elastic Load Balancing distributes incoming traffic across multiple EC2 instances, improving both availability and fault tolerance by ensuring that requests are evenly distributed and that traffic is automatically rerouted in the event of instance failures.
Question 60 When designing a system, you adhere to the principle of “design for failure and nothing will fail.” Which of the following AWS services/features can support this design principle? Select three options from the choices below.
a) Availability Zones
b) Regions
c) Elastic Load Balancer
d) Pay as you go
Answer is: (a) Availability Zones, (b) Regions, and (c) Elastic Load Balancer
Explanation: Adhering to the principle of designing for failure involves building systems that can tolerate failures at various levels without impacting overall functionality. To support this design principle, three AWS services/features that can be leveraged are Availability Zones, Regions, and Elastic Load Balancers. Availability Zones are distinct data centers within a region that are engineered to be isolated from failures in other Availability Zones. Regions consist of multiple Availability Zones and provide geographic resilience. Elastic Load Balancers distribute incoming traffic across multiple instances, providing fault tolerance by automatically rerouting traffic in the event of instance failures. The “pay as you go” option (D) is not directly related to supporting the design principle of failure resilience.
