Amazon (SAP-C01) Exam Questions And Answers page 39

An enterprise runs 103 line-of-business applications on virtual machines in an on-premises data center. Many of the applications are simple PHP, Java, or Ruby web applications, are no longer actively developed, and serve little traffic.

Which approach should be used to migrate these applications to AWS with the LOWEST infrastructure costs?
Implementing cost control strategies
An enterprise wants to use a third-party SaaS application. The SaaS application needs to have access to issue several API commands to discover Amazon EC2 resources running within the enterprise's account The enterprise has internal security policies that require any outside access to their environment must conform to the principles of least privilege and there must be controls in place to ensure that the credentials used by the SaaS vendor cannot be used by any other third party.

Which of the following would meet all of these conditions?
Designing for security and compliance
An ERP application is deployed across multiple AZs in a single region. In the event of failure, the Recovery Time Objective (RTO) must be less than 3 hours, and the Recovery Point Objective (RPO) must be 15 minutes. The customer realizes that data corruption occurred roughly 1.5 hours ago.

What DR strategy could be used to achieve this RTO and RPO in the event of this kind of failure?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing enterprise-wide scalable operations on AWS
A newspaper organization has an on-premises application which allows the public to search its back catalogue and retrieve individual newspaper pages via a website written in Java. They have scanned the old newspapers into JPEGs (approx 17TB) and used Optical Character Recognition (OCR) to populate a commercial search product. The hosting platform and software are now end of life and the organization wants to migrate its archive to AWS and produce a cost efficient architecture and still be designed for availability and durability.

Which is the most appropriate?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing enterprise-wide scalable operations on AWS

A new startup is running a serverless application using AWS Lambda as the primary source of compute. New versions of the application must be made available to a subset of users before deploying changes to all users. Developers should also have the ability to abort the deployment and have access to an easy rollback mechanism. A solutions architect decides to use AWS CodeDeploy to deploy changes when a new version is available.

Which CodeDeploy configuration should the solutions architect use?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing for security and compliance
An IAM user is trying to perform an action on an object belonging to some other root account's bucket.

Which of the below mentioned options will AWS S3 not verify?
Designing highly available, cost-efficient, fault-tolerant, scalable systems
An internal security audit of AWS resources within a company found that a number of Amazon EC2 instances running Microsoft Windows workloads were missing several important operating system-level patches. A Solutions Architect has been asked to fix existing patch deficiencies, and to develop a workflow to ensure that future patching requirements are identified and taken care of quickly. The Solutions Architect has decided to use AWS Systems Manager. It is important that EC2 instance reboots do not occur at the same time on all Windows workloads to meet organizational uptime requirements.

Which workflow will meet these requirements in an automated manner?
Designing for security and compliance
An International company has deployed a multi-tier web application that relies on DynamoDB in a single region. For regulatory reasons they need disaster recovery capability in a separate region with a Recovery Time Objective of 2 hours and a Recovery Point Objective of 24 hours. They should synchronize their data on a regular basis and be able to provision me web application rapidly using CloudFormation.
The objective is to minimize changes to the existing web application, control the throughput of DynamoDB used for the synchronization of data and synchronize only the modified elements.

Which design would you choose to meet these requirements?
Designing highly available, cost-efficient, fault-tolerant, scalable systems Designing for security and compliance
An IoT company has rolled out a fleet of sensors for monitoring temperatures in remote locations. Each device connects to AWS IoT Core and sends a message 30 seconds, updating an Amazon DynamoDB table. A System Administrator users AWS IoT to verify the devices are still sending messages to AWS IoT Core: the database is not updating.

What should a Solutions Architect check to determine why the database is not being updated?
