The company's current investment in on-premises backup systems and procedures must be protected. What recommendations should a solutions architect make? Set up AWS Storage Gateway to connect with the backup applications using the NFS interface. Set up an Amazon Elastic File System (Amazon EFS) file system that connects with the backup applications using the NFS interface. Set up an Amazon Elastic File System (Amazon EFS) file system that connects with the backup applications using the iSCSI interface. Set up AWS Storage Gateway to connect with the backup applications using the iSCSI-virtual tape library (VTL) interface.
A business maintains an internal web-based application. The application is deployed on Amazon EC2 instances that are routed via an Application Load Balancer. The instances are distributed across several Availability Zones through an Amazon EC2 Auto Scaling group. During business hours, the Auto Scaling group grows up to 20 instances, then scales down to two instances overnight. Staff are saying that the program is very sluggish to start the day, but performs fine by mid-morning. How might the scale be altered to accommodate employee concerns while keeping expenses low? Implement a scheduled action that sets the desired capacity to 20 shortly before the office opens. Implement a step scaling action triggered at a lower CPU threshold, and decrease the cooldown period. Implement a target tracking action triggered at a lower CPU threshold, and decrease the cooldown period. Implement a scheduled action that sets the minimum and maximum capacity to 20 shortly before the office opens.
A business must adhere to a regulatory obligation that all emails be saved and preserved outside for a period of seven years. An administrator has prepared compressed email files on-premises and wishes to have the data transferred to AWS storage through a managed service. Which managed service should be recommended by a solutions architect? Amazon Elastic File System (Amazon EFS) Amazon S3 Glacier AWS Backup AWS Storage Gateway.
A business hosts its website on Amazon EC2 instances that are distributed across several Availability Zones through an Elastic Load Balancer. The instances are managed as part of an EC2 Auto Scaling group. The website stores product manuals for download through Amazon Elastic Block Store (Amazon EBS) volumes. The organization often changes the product information, which means that new instances created by the Auto Scaling group frequently have out-of-date data. It may take up to 30 minutes for all changes to be received by fresh instances. Additionally, the changes involve resizing the EBS volumes during business hours. The corporation want to guarantee that product manuals are constantly current and that the architecture adapts fast to rising customer demand. A solutions architect must satisfy these objectives without requiring the business to upgrade its application code or website. What actions should the solutions architect take to achieve this objective? Store the product manuals in an EBS volume. Mount that volume to the EC2 instances. Store the product manuals in an Amazon S3 bucket. Redirect the downloads to this bucket. Store the product manuals in an Amazon Elastic File System (Amazon EFS) volume. Mount that volume to the EC2 instances. Store the product manuals in an Amazon S3 Standard-Infrequent Access (S3 Standard-IA) bucket. Redirect the downloads to this bucket.
On Amazon EC2, a business hosts an ecommerce application. The application is composed of a stateless web layer that needs a minimum of 10 instances and a maximum of 250 instances to run. 80% of the time, the program needs 50 instances. Which solution should be adopted in order to keep expenses down? Purchase Reserved Instances to cover 250 instances. Purchase Reserved Instances to cover 80 instances. Use Spot Instances to cover the remaining instances. Purchase On-Demand Instances to cover 40 instances. Use Spot Instances to cover the remaining instances. Purchase Reserved Instances to cover 50 instances. Use On-Demand and Spot Instances to cover the remaining instances.
A business intends to install an Amazon RDS database instance powered by Amazon Aurora. The organization has a 90-day backup retention policy. Which solution, if any, should a solutions architect suggest? Set the backup retention period to 90 days when creating the RDS DB instance. Configure RDS to copy automated snapshots to a user-managed Amazon S3 bucket with a lifecycle policy set to delete after 90 days. Create an AWS Backup plan to perform a daily snapshot of the RDS database with the retention set to 90 days. Create an AWS Backup job to schedule the execution of the backup plan daily. Use a daily scheduled event with Amazon CloudWatch Events to execute a custom AWS Lambda function that makes a copy of the RDS automated snapshot. Purge snapshots older than 90 days.
A solutions architect is configuring a virtual private cloud (VPC) with public and private subnets. The VPC and subnets are configured using IPv4 CIDR blocks. Each of the three Availability Zones (AZs) has one public and one private subnet. An internet gateway is used to connect public subnets to the internet. Private subnets must have internet connectivity in order for Amazon EC2 instances to obtain software upgrades. What should the solutions architect do to allow private subnets to connect to the internet? Create three NAT gateways, one for each public subnet in each AZ. Create a private route table for each AZ that forwards non-VPC traffic to the NAT gateway in its AZ. Create three NAT instances, one for each private subnet in each AZ. Create a private route table for each AZ that forwards non-VPC traffic to the NAT instance in its AZ. Create a second internet gateway on one of the private subnets. Update the route table for the private subnets that forward non-VPC traffic to the private internet gateway. Create an egress-only internet gateway on one of the public subnets. Update the route table for the private subnets that forward non-VPC traffic to the egress- only internet gateway.
Currently, a corporation has 250 TB of backup data saved in Amazon S3 using a vendor-specific format. The firm wishes to extract files from Amazon S3, convert them to an industry-standard format, and then re-upload them to Amazon S3. The firm want to reduce the costs connected with data transmission for this session. What actions should a solutions architect take to achieve this? Install the conversion software as an Amazon S3 batch operation so the data is transformed without leaving Amazon S3. Install the conversion software onto an on-premises virtual machine. Perform the transformation and re-upload the files to Amazon S3 from the virtual machine. Use AWS Snowball Edge devices to export the data and install the conversion software onto the devices. Perform the data transformation and re-upload the files to Amazon S3 from the Snowball Edge devices. Launch an Amazon EC2 instance in the same Region as Amazon S3 and install the conversion software onto the instance. Perform the transformation and re- upload the files to Amazon S3 from the EC2 instance.
A business's applications are hosted on on-premises servers. The corporation is rapidly depleting its storage capacity. The programs make use of both block and network file storage. The business need a high-performance solution that enables local caching without requiring it to re-architect its current applications. Which steps should a solutions architect perform in combination to satisfy these requirements? (Select two.) Mount Amazon S3 as a file system to the on-premises servers. Deploy an AWS Storage Gateway file gateway to replace NFS storage. Deploy AWS Snowball Edge to provision NFS mounts to on-premises servers. Deploy an AWS Storage Gateway volume gateway to replace the block storage. Deploy Amazon Elastic Fife System (Amazon EFS) volumes and mount them to on-premises servers.
A business hosts a web service on Amazon EC2 instances that are routed via an Application Load Balancer. The instances are distributed across two Availability Zones through an Amazon EC2 Auto Scaling group. At all times, the corporation requires a minimum of four instances to achieve the needed service level agreement (SLA) requirements while keeping expenses low. How can the organization maintain compliance with the SLA if an Availability Zone fails? Add a target tracking scaling policy with a short cooldown period. Change the Auto Scaling group launch configuration to use a larger instance type. Change the Auto Scaling group to use six servers across three Availability Zones. Change the Auto Scaling group to use eight servers across two Availability Zones.
A firm is using the AWS Cloud to run a three-tier ecommerce application. The firm hosts the website on Amazon S3 and combines it with a sales API. The API is hosted by the firm on three Amazon EC2 instances that are connected through an Application Load Balancer (ALB). The API is composed of static and dynamic front-end content, as well as back-end workers that asynchronously execute sales requests. The corporation anticipates a big and abrupt surge in sales requests during events celebrating the introduction of new items. What should a solutions architect prescribe to assure the effective processing of all requests? Add an Amazon CloudFront distribution for the dynamic content. Increase the number of EC2 instances to handle the increase in traffic. Add an Amazon CloudFront distribution for the static content. Place the EC2 instances in an Auto Scaling group to launch new instances based on network traffic. Add an Amazon CloudFront distribution for the dynamic content. Add an Amazon ElastiCache instance in front of the ALB to reduce traffic for the API to handle. Add an Amazon CloudFront distribution for the static content. Add an Amazon Simple Queue Service (Amazon SQS) queue to receive requests from the website for later processing by the EC2 instances. .
Amazon EC2 instances are used to execute an application. The application's sensitive data is housed in an Amazon S3 bucket. The bucket must be shielded from internet access while yet allowing access to it for services inside the VPC. Which activities should solutions archived take in order to do this? (Select two.) Create a VPC endpoint for Amazon S3. Enable server access logging on the bucket. Apply a bucket policy to restrict access to the S3 endpoint. Add an S3 ACL to the bucket that has sensitive information. Restrict users using the IAM policy to use the specific bucket.
A business's program creates a vast number of files, each around 5 MB in size. Amazon S3 is used to store the files. According to company policy, files must be retained for a period of four years before they may be erased. Immediate access is always essential due to the fact that the files contain vital business data that is difficult to replicate. The files are commonly viewed within the first 30 days after the establishment of the item, but are seldom accessed beyond that time period. Which storage option is the most cheapest? Create an S3 bucket lifecycle policy to move files from S3 Standard to S3 Glacier 30 days from object creation. Delete the files 4 years after object creation. Create an S3 bucket lifecycle policy to move files from S3 Standard to S3 One Zone-Infrequent Access (S3 One Zone-IA) 30 days from object creation. Delete the files 4 years after object creation.
