1. A solution architect must migrate a Windows internet information Services (IIS) web application to AWS. The application currently relies on a file share hosted in the user's on-premises network-attached storage (NAS).The solution architected has proposed migrating the IIS web serversWhich replacement to the on-promises file share is MOST resilient and durable?

A) Migrate the tile Share to AWS Storage Gateway
B) Migrate the file Share to Amazon RDS.
C) Migrate the tile share to Amazon Elastic File System (Amazon EFS)
D) Migrate the file Share to Amazon FSx for Windows File Server.



2. An application running on AWS uses an Amazon Aurora Multi-AZ deployment for its database. When evaluating performance metrics, a solutions architect discovered that the database reads are causing high I/O and adding latency to the write requests against the database.What should the solutions architect do to separate the read requests from the write requests?

A) Create a read replica and modify the application to use the appropriate endpoint.
B) Enable read-through caching on the Amazon Aurora database.
C) Update the application to read from the Multi-AZ standby instance.
D) Create a second Amazon Aurora database and link it to the primary database as a read replica.



3. A company is hosting a web application on AWS using a single Amazon EC2 instance that stores user-uploaded documents in an Amazon EBS volume. For better scalability and availability, the company duplicated the architecture and created a second EC2 instance and EBS volume in another Availability Zone, placing both behind an Application Load Balancer. After completing this change, users reported that, each time they refreshed the website, they could see one subset of their documents or the other, but never all of the documents at the same time. What should a solutions architect propose to ensure users see all of their documents at once?

A) Copy the data so both EBS volumes contain all the documents.
B) Configure the Application Load Balancer to direct a user to the server with the documents.
C) Copy the data from both EBS volumes to Amazon EFS. Modify the application to save new documents to Amazon EFS.
D) Configure the Application Load Balancer to send the request to both servers. Return each document from the correct server.



4. A company is planning to migrate its virtual server-based workloads to AWS. The company has internet-facing load balancers backed by application servers. The application servers rely on patches from an internet-hosted repositoryWhich services should a solutions architect recommend be hosted on the public subnet? (Choose two.)(Select 2answers)

A) Application Load Balancers
B) NAT gateway
C) Amazon RDS DB instances
D) Amazon Elastic File System (Amazon EFS) volumes
E) Amazon EC2 application servers


5. A company collects temperature, humidity, and atmospheric pressure data in cities across multiple continents. The average volume of data collected per site each day is 500 GB. Each site has a high-speed internet connection. The company's weather forecasting applications are based in a single Region and analyze the data daily. What is the FASTEST way to aggregate data for all of these global sites?

A) Schedule AWS Snowball jobs daily to transfer data to the closest AWS Region. Use S3 cross-Region replication to copy objects to the destination bucket.
B) Upload the data to an Amazon EC2 instance in the closes Region. Store the data in an Amazon EBS volume. One a day take an EBS snapshot and copy it to the centralize Region. Restore the EBS volume in the centralized Region and run an analysis on the data daily.
C) Upload site data to an Amazon S3 bucket in the closest AWS Region. Use S3 cross-Region replication to copy objects to the destination bucket.
D) Enable Amazon S3 Transfer Acceleration on the destination bucket. Use multipart uploads to directly upload site data to the destination bucket.
