1. A company hosts its website on AWS. To address the highly variable demand, the company has implemented Amazon EC2 Auto Scaling. Management is concerned that the company is over-provisioning its infrastructure, especially at the front end of the three-tier application. A solution architect needs to ensure costs are optimized without impacting performance.What should the solutions architect do to accomplish this?

A) Use Auto Scaling with a scheduled scaling policy
B) Use Auto Scaling with the suspend-resume feature
C) Use Auto Scaling with a target tracking scaling policy
D) Use Auto Scaling with Reserved Instances



2. A company has an on-premises data center that is running out of storage capacity. The company wants to migrate its storage infrastructure to AWS while minimizing bandwidth costs. The solution must allow for immediate retrieval of data at no additional cost.How can these requirements be met?

A) Deploy Amazon S3 Glacier Vault and enable expedited retrieval. Enable provisioned retrieval capacity for the workload.
B) Deploy AWS Direct Connect to connect with the on-premises data center. Configure AWS Storage Gateway to store data locally. Use Storage Gateway to asynchronously back up point-in-time snapshots of the data to Amazon S3.
C) Deploy AWS Storage Gateway using stored volumes to store data locally. Use Storage Gateway to asynchronously back up point-in-time snapshots of the data to Amazon S3.
D) Deploy AWS Storage Gateway using cached volumes. Use Storage Gateway to store data in Amazon S3 while retaining copies of frequently accessed data subsets locally.



3. A company recently implemented hybrid cloud connectivity using AWS Direct Connect and is migrating data to Amazon S3. The company is looking for a fully managed solution that will automate and accelerate the replication of data between the on-premises storage systems and AWS storage services.Which solution should a solutions architect recommend to keep the data private?

A) Deploy an AWS DataSync agent for the on-premises environment. Schedule a batch job to replicate point-ln-time snapshots to AWS.
B) Deploy an AWS Storage Gateway file gateway for the on-premises environment. Configure it to store data locally, and asynchronously back up point-in-lime snapshots to AWS.
C) Deploy an AWS DataSync agent tor the on-premises environment. Configure a sync job to replicate the data and connect it with an AWS service endpoint.
D) Deploy an AWS Storage Gateway volume gateway for the on-premises environment. Configure it to store data locally, and asynchronously back up point-in- time snapshots to AWS.



4. A company wants to use Amazon S3 for the secondary copy of its on-premises dataset. The company would rarely need to access this copy. The storage solution's cost should be minimal.Which storage solution meets these requirements?

A) S3 One Zone-Infrequent Access (S3 One Zone-IA)
B) S3 Standard-Infrequent Access (S3 Standard-IA)
C) S3 Intelligent-Tiering
D) S3 Standard



5. A company's web application is running on Amazon EC2 instances behind an Application Load Balancer. The company recently changed its policy, which now requires the application to be accessed from one specific country only.Which configuration will meet this requirement?

A) Configure the security group on the Application Load Balancer.
B) Configure the security group for the EC2 instances.
C) Configure the network ACL for the subnet that contains the EC2 instances.
D) Configure AWS WAF on the Application Load Balancer in a VPC.
