A company has more than 10,000 sensors that send data to an on-premises Apache Kafka server by using the Message Queuing Telemetry Transport (MQTT) protocol. The on-premises Kafka server transforms the data and then stores the
results as objects in an Amazon S3 bucket.
Recently, the Kafka server crashed. The company lost sensor data while the server was being restored. A solutions architect must create a new design on AWS that is highly available and scalable to prevent a similar occurrence.
Which solution will meet these requirements?
A. Launch two Amazon EC2 instances to host the Kafka server in an active/standby configuration across two Availability Zones. Create a domain name in Amazon Route 53. Create a Route 53 failover policy. Route the sensors to send the data to the domain name.Which statement is NOT true about a stack which has been created in a Virtual Private Cloud (VPC) in AWS OpsWorks?
A. Subnets whose instances cannot communicate with the Internet are referred to as public subnets.A data analytics company has an Amazon Redshift cluster that consists of several reserved nodes. The cluster is experiencing unexpected bursts of usage because a team of employees is compiling a deep audit analysis report. The queries
to generate the report are complex read queries and are CPU intensive.
Business requirements dictate that the cluster must be able to service read and write queries at all times. A solutions architect must devise a solution that accommodates the bursts of usage.
Which solution meets these requirements MOST cost-effectively?
A. Provision an Amazon EMR cluster. Offload the complex data processing tasks.A sys admin is maintaining an application on AWS. The application is installed on EC2 and user has configured ELB and Auto Scaling. Considering future load increase, the user is planning to launch new servers proactively so that they get registered with ELB.
How can the user add these instances with Auto Scaling?
A. Decrease the minimum limit of the Auto Scaling groupA company has a photo sharing social networking application. To provide a consistent experience for users, the company performs some image processing on the photos uploaded by users before publishing on the application. The image processing is implemented using a set of Python libraries.
The current architecture is as follows:
1.
The image processing Python code runs in a single Amazon EC2 instance and stores the processed images in an Amazon S3 bucket named ImageBucket.
2.
The front-end application, hosted in another bucket, loads the images from ImageBucket to display to users.
With plans for global expansion, the company wants to implement changes in its existing architecture to be able to scale for increased demand on the application and reduce management complexity as the application scales.
Which combination of changes should a solutions architect make? (Choose two.)
A. Place the image processing EC2 instance into an Auto Scaling group.A group of Amazon EC2 instances have been configured as a high performance computing (HPC) cluster. The instances are running in a placement group, and are able to communicate with each other at network speeds of up to 20 Gbps.
The cluster needs to communicate with a control EC2 instance outside of the placement group. The control instance has the same instance type and AMI as the other instances, and is configured with a public IP address.
How can the Solutions Architect improve the network speeds between the control instance and the instances in the placement group?
A. Terminate the control instance and relaunch it in the placement group.You would like to create a mirror image of your production environment in another region for disaster recovery purposes. Which of the following AWS resources do not need to be recreated in the second region? (Choose two.)
A. Route 53 Record SetsA company is running an application in the AWS Cloud. The application uses AWS Lambda functions and Amazon Elastic Container Service (Amazon ECS) containers that run with AWS Fargate technology as its primary compute. The load on the application is irregular. The application experiences long periods of no usage, followed by sudden and significant increases and decreases in traffic. The application is write-heavy and stores data in an Amazon Aurora MySQL database. The database runs on an Amazon RDS memory optimized D8 instance that is not able to handle the load.
What is the MOST cost-effective way for the company to handle the sudden and significant changes in traffic?
A. Add additional read replicas to the database. Purchase Instance Savings Plans and RDS Reserved Instances.A company is running a web application on Amazon EC2 instances in a production AWS account. The company requires all logs generated from the web application to be copied to a central AWS account (or analysis and archiving. The
company's AWS accounts are currently managed independently. Logging agents are configured on the EC2 instances to upload the tog files to an Amazon S3 bucket in the central AWS account.
A solutions architect needs to provide access for a solution that will allow the production account to store log files in the central account. The central account also needs to have read access to the tog files.
What should the solutions architect do to meet these requirements?
A. Create a cross-account role in the central account. Assume the role from the production account when the logs are being copied.A company runs an application that gives users the ability to search for videos and related information by using keywords that are curated from content providers. The application data is stored in an on-premises Oracle database that is 800 GB in size.
The company wants to migrate the data to an Amazon Aurora MySQL DB instance. A solutions architect plans to use the AWS Schema Conversion Tool and AWS Database Migration Service (AWS DMS) for the migration. During the migration, the existing database must serve ongoing requests. The migration must be completed with minimum downtime.
Which solution will meet these requirements?
A. Create primary key indexes, secondary indexes, and referential integrity constraints in the target database before starting the migration process.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
