A company runs its ecommerce application on AWS. Every new order is published as a message in a RabbitMQ queue that runs on an Amazon EC2 instance in a single Availability Zone. These messages are processed by a different application that runs on a separate EC2 instance. This application stores the details in a PostgreSQL database on another EC2 instance. All the EC2 instances are in the same Availability Zone.
The company needs to redesign its architecture to provide the highest availability with the least operational overhead.
What should a solutions architect do to meet these requirements?
A. Migrate the queue to a redundant pair (active/standby) of RabbitMQ instances on Amazon MQ. Create a Multi-AZ Auto Scaling group (or EC2 instances that host the application. Create another Multi-AZ Auto Scaling group for EC2 instances that host the PostgreSQL database.A company is using a fleet of Amazon EC2 instances to ingest data from on-premises data sources. The data is in JSON format and Ingestion rates can be as high as 1 MB/s. When an EC2 instance is rebooted, the data in-flight is lost. The company's data science team wants to query Ingested data In near-real time.
Which solution provides near-real -time data querying that is scalable with minimal data loss?
A. Publish data to Amazon Kinesis Data Streams Use Kinesis data Analytics to query the data.A company that primarily runs its application servers on premises has decided to migrate to AWS. The company wants to minimize its need to scale its Internet Small Computer Systems Interface (iSCSI) storage on premises. The company wants only its recently accessed data to remain stored locally.
Which AWS solution should the company use to meet these requirements?
A. Amazon S3 File GatewayA news company that has reporters all over the world is hosting its broadcast system on AWS. The reporters send live broadcasts to the broadcast system. The reporters use software on their phones to send live streams through the Real
Time Messaging Protocol (RTMP).
A solutions architect must design a solution that gives the reporters the ability to send the highest quality streams. The solution must provide accelerated TCP connections back to the broadcast system.
What should the solutions architect use to meet these requirements?
A. Amazon CloudFrontA company is planning to migrate a commercial off-the-shelf application from its on-premises data center to AWS. The software has a software licensing model using sockets and cores with predictable capacity and uptime requirements. The
company wants to use its existing licenses, which were purchased earlier this year.
Which Amazon EC2 pricing option is the MOST cost-effective?
A. Dedicated Reserved HostsA company copies 200 TB of data from a recent ocean survey onto AWS Snowball Edge Storage Optimized devices The company has a high performance computing (HPC) cluster that is hosted on AWS to look for oil and gas deposits A solutions architect must provide the cluster with consistent sub- millisecond latency and high-throughput access to the data on the Snowball Edge Storage Optimized devices The company is sending the devices back to AWS
Which solution will meet these requirements'?
A. Create an Amazon S3 bucket Import the data into the S3 bucket Configure an AWS Storage Gateway file gateway to use the S3 bucket Access the file gateway from the HPC cluster instancesA company runs a high performance computing (HPC) workload on AWS. The workload required low- latency network performance and high network throughput with tightly coupled node-to-node communication. The Amazon EC2 instances
are properly sized for compute and storage capacity, and are launched using default options.
What should a solutions architect propose to improve the performance of the workload?
A. Choose a cluster placement group while launching Amazon EC2 instancesA company has an internet-facing application that runs on premises. The application contains mostly user- generated content. The data is stored in an on-premises network- attached storage system. The company wants to archive this data annually and has chosen to move the archival data to Amazon S3. The company needs a solution to migrate the archival data into an S3 bucket.
Which solution will meet these requirements?
A. Use AWS Storage Gateway Volume Gateway. Cache the data, and then replicate the data from the on- premises environment to Amazon S3.A public-facing web application queries a database hosted on a Amazon EC2 instance in a private subnet. A large number of queries involve multiple table joins, and the application performance has been degrading due to an increase in
complex queries. The application team will be performing updates to improve performance.
What should a solutions architect recommend to the application team? (Select TWO.)
A. Cache query data in Amazon SQSA solutions architect is designing the storage architecture for a new web application used for stonng and viewing engineering drawings. All application components will be deployed on the AWS infrastructure. The application design must support caching to minimize the amount of time that users wait for the engineering drawings to load. The application must be able to store petabytes of data.
Which combination of storage and caching should the solutions architect use?
A. Amazon S3 with Amazon CloudFrontNowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
