A global media company allows users to upload large video files to an Amazon S3 bucket located in the us-east-1 Region. Users in Australia are experiencing slow upload speeds. What is the MOST effective way to improve the upload performance for these users?
A database running on an Amazon EC2 instance requires a block storage volume that can provide 15,000 IOPS. The workload is consistent, and cost is a consideration, but performance must be guaranteed. Which Amazon EBS volume type is the MOST cost-effective choice that meets the performance requirement?
A company has a read-heavy application backed by Amazon DynamoDB. The application is experiencing high latency during peak hours due to the volume of read requests. The solutions architect needs to implement a caching layer to improve read performance to microsecond latency. Which TWO solutions can achieve this? (Select TWO.)
A global media company allows users to upload large video files to an Amazon S3 bucket located in the us-east-1 region. Users in Australia are experiencing slow upload speeds. How can the solutions architect improve the upload performance?
A database administrator is provisioning storage for a high-performance relational database on Amazon EC2. The database requires sustained performance of 64,000 IOPS. Which TWO Amazon EBS volume types can meet this requirement? (Select TWO.)
A company is using Amazon EFS for a big data analytics workload. Hundreds of EC2 instances are reading and writing to the file system simultaneously. The application is experiencing high latency. Which EFS performance mode should be used?
A database requires 60,000 IOPS and sub-millisecond latency. The data must persist even if the EC2 instance is stopped or terminated. Which TWO storage options could meet these requirements? (Select TWO.)
A global media company allows users to upload large video files to an Amazon S3 bucket located in the us-east-1 region. Users in Australia are experiencing slow upload speeds. What is the MOST effective way to improve upload performance for these users?
A big data application running on hundreds of EC2 instances needs to read and write to a shared Amazon EFS file system. The application is experiencing high latency and the CloudWatch metrics show the `PercentIOLimit` is reaching 100%. How can performance be improved?
A company has a legacy application that requires a POSIX-compliant file system. The application runs on multiple Amazon EC2 Linux instances across multiple Availability Zones. All instances must have concurrent read and write access to the same file system. <br/><br/>Which storage solution should be used?
A database running on Amazon EC2 requires an Amazon EBS volume that can provide 64,000 IOPS and consistent sub-millisecond latency. <br/><br/>Which EBS volume type should the solutions architect choose?
A database running on an EC2 instance requires block storage. The workload is highly transactional and requires sustained performance of 64,000 IOPS. Which TWO EBS volume types can meet this requirement? (Select TWO.)
A company needs to upload 100 GB files to an Amazon S3 bucket from locations around the world. The uploads are currently taking too long over the public internet. What is the MOST effective way to speed up these uploads?
A machine learning application processes thousands of small files concurrently from an Amazon EFS file system. The application is experiencing high latency. The solutions architect notices that the EFS Burst Credits are frequently exhausted. Which TWO actions should be taken to improve performance? (Select TWO.)
An application downloads large video files from Amazon S3. Users often skip to the middle of a video. To improve performance and reduce data transfer, the application should only download the specific portion of the file being requested. How can this be achieved?
A global media company allows users to upload large video files to an Amazon S3 bucket located in the us-east-1 region. Users in Asia and Europe are experiencing slow upload speeds due to high latency over the public internet.<br/><br/>Which S3 feature should a solutions architect enable to improve upload performance for global users?
A database running on an EC2 instance requires an EBS volume. The database workload requires 10,000 IOPS. The company wants to provision this performance at the lowest possible cost.<br/><br/>Which EBS volume type should be selected?
A big data application runs on hundreds of EC2 instances and reads data from a shared Amazon EFS file system. The application is experiencing high latency. CloudWatch metrics show that the PercentIOLimit metric is frequently hitting 100%.<br/><br/>Which TWO actions should a solutions architect take to improve performance? (Select TWO.)
A database application running on an EC2 instance requires a block storage volume that can sustain 64,000 IOPS and provides sub-millisecond latency. Which Amazon EBS volume type should be used?
A global user base frequently uploads large video files (up to 5 GB) to an Amazon S3 bucket located in the us-east-1 region. Users in Asia and Europe are experiencing slow upload speeds. What is the MOST effective way to improve upload performance for these users?
An application requires a shared file system. The workload is highly parallel and requires massive throughput (up to 10 GB/s) for a high-performance computing (HPC) cluster running on Linux. Which TWO storage solutions could meet this requirement? (Select TWO.)
