Question1: A company wants to migrate its website from an on-premises data center onto AWS. At the same time, it wants to migrate the website to a containerized microservice-based architecture to improve the availability and cost efficiency. The company's security policy states that privileges and network permissions must be configured according to best practice, using least privilege.
A Solutions Architect must create a containerized architecture that meets the security requirements and has deployed the application to an Amazon ECS cluster.
What steps are required after the deployment to meet the requirements? (Choose two.)

Question2: A company is running a commercial Apache Hadoop cluster on Amazon EC2. This cluster is being used daily to query large files on Amazon S3. The data on Amazon S3 has been curated and does not require any additional transformations steps. The company is using a commercial business intelligence (BI) tool on Amazon EC2 to run queries against the Hadoop cluster and visualize the data.
The company wants to reduce or eliminate the overhead costs associated with managing the Hadoop cluster and the BI tool. The company would like to remove to a more cost-effective solution with minimal effort. The visualization is simple and requires performing some basic aggregation steps only.
Which option will meet the company's requirements?

Question3: A company has an application behind a load balancer with enough Amazon EC2 instances to satisfy peak demand. Scripts and third-party deployment solutions are used to configure EC2 instances when demand increases or an instance fails. The team must periodically evaluate the utilization of the instance types to ensure that the correct sizes are deployed.
How can this workload be optimized to meet these requirements?

Question4: A retail company processes point-of-state data on application servers in its data center and writes outputs to Amazon DynamoDB table. The data center is connected to the company's VPC with an AWS Direct Connect (DX) connection, and the application servers require a consistent network connection at speed greater than 2 Gbps.
The company decides that the DynamoDB table needs to be highly available and fault tolerant. The company policy states that the data should be available across two regions.

Which of the following solutions should the Solutions Architect recommend?

Question6: A company currently has data hosted in an IBM Db2 database A web application calls an API that runs stored procedures on the database to retrieve user information data that is read-only. This data is historical in nature and changes on a daily basis. When a user logs in to the application, this data needs to be retrieved within 3 seconds. Each time a user logs in. the stored procedures run. Users log in several times a day to check stock prices.
Running this database has become cost-prohibitive due to Db2 CPU licensing. Performance goals are not being met. Timeouts from Db2 are common due to long-running queries Which approach should a solutions architect take to migrate this solution to AWS?

Question7: A utility company wants to collect usage data every 5 minutes from its smart meters to facilitate time-of-use metering When a meter sends data to AWS the data is sent to Amazon API Gateway, processed by an AWS Lambda function and stored in an Amazon DynamoDB table During the pilot phase, the Lambda functions took from 3 to 5 seconds to complete As more smart meters are deployed, the Engineers notice the Lambda functions are taking from 1 to 2 minutes to complete The functions are also increasing in duration as new types of metrics are collected from the devices There are many ProvisionedThroughputExceededException errors while performing PUT operations on DynamoDB and there are also many TooMany Requests Exception errors from Lambda.

Question10: An enterprise company wants to allow its developers to purchase third-party software through AWS Marketplace. The company uses an AWS Organizations account structure with full features enabled, and has a shared services account in each organizational unit (OU) that will be used by procurement managers. The procurement team's policy indicates that developers should be able to obtain third-party software from an approved list only and use Private Marketplace in AWS Marketplace to achieve this requirement. The procurement team wants administration of Private Marketplace to be restricted to a role named procurement-manager-role, which could be assumed by procurement managers. Other IAM users, groups, roles, and account administrators in the company should be denied Private Marketplace administrative access.

Up to 10 business unit VPCs will need to be connected to the shared VPC Some of the business unit VPC CIDR blocks overlap with the shared VPC and some overlap with each other Network connectivity to the centralized application in the shared VPC should be allowed from authorized business unit VPCs only Which network configuration should a solutions architect use to provide connectivity from the client applications in the business unit VPCs to the centralized application in the shared VPC?

Question64: A company needs to move its on-premises resources to AWS. The current environment consists of 100 virtual machines (VMs) with a total of 40 TB of storage. Most of the VMs can be taken offline because they support functions during business hours only; however, some are mission critical, so downtime must be minimized.
