Your company runs a customer facing event registration site This site is built with a 3-tier architecture with web and application tier servers and a MySQL database The application requires 6 web tier servers and 6 application tier servers for normal operation, but can run on a minimum of 65% server capacity and a single MySQL database. When deploying this application in a region with three availability zones (AZs) which architecture provides high availability?
A. A web tier deployed across 2 AZs with 3 EC2 (Elastic Compute Cloud) instances in each AZ inside an Auto Scaling Group behind an ELB (elastic load balancer), and an application tier deployed across 2 AZs with 3 EC2 instances in each AZ inside an Auto Scaling Group behind an ELB, and one RDS (Relational Database Service) instance deployed with read replicas in the other AZ.Fill in the blanks: The base URI for all requests for instance metadata is ___________
A. http://254.169.169.254/latest/A company plans to migrate a website to AWS to use a serverless architecture. The website contains both static and dynamic content and is accessed by users across the world. The website should maintain sessions for returning users to improve the user experience.
Which service should a Solutions Architect use for a cost-efficient solution with the LOWEST latency?
A. Amazon S3, AWS Lambda, Amazon API Gateway, and Amazon DynamoDBAn interactive, dynamic website runs on Amazon EC2 instances in a single subnet behind an ELB Classic Load Balancer. Which design changes will make the site more highly available?
A. Move some Amazon EC2 instances to a subnet in a different way.A call center application consists of a three-tier application using Auto Scaling groups to automatically scale resources as needed. Users report that every morning at 9:00 AM the system becomes very slow for about 15 minutes. A Solution Architect determines that a large percentage of the call center staff starts work at 9:00 AM, so Auto Scaling does not have enough time to scale out to meet demand.
How can the Architect fix the problem?
A. Change the Auto Scaling group's scale out event to scale based on network utilization.A Solutions Architect needs to design a solution that will enable a security team to detect, review, and perform root cause analysis of security incidents that occur in a cloud environment. The Architect must provide a centralized view of all API
events for current and future AWS regions.
How should the Architect accomplish this task?
A. Enable AWS CloudTrail logging in each individual region. Repeat this for all future regions.A customer has a 10 GB AWS Direct Connect connection to an AWS region where they have a web application hosted on Amazon Elastic Computer Cloud (EC2). The application has dependencies on an on-premises mainframe database that uses a BASE (Basic Available. Sort stale Eventual consistency) rather than an ACID (Atomicity. Consistency isolation. Durability) consistency model. The application is exhibiting undesirable behavior because the database is not able to handle the volume of writes. How can you reduce the load on your on-premises database resources in the most cost-effective way?
A. Use an Amazon Elastic Map Reduce (EMR) S3DistCp as a synchronization mechanism between the on-premises database and a Hadoop cluster on AWS.An organization uses Amazon S3 to store video content served via its website. It only has rights to deliver this content to users within its own country and needs to restrict access. How can the organization ensure that these files are only accessible from within its country?
A. Use a custom Amazon S3 bucket policy to allow access only to users inside the organization's countryA Solutions Architect is designing a web application that will be hosted on Amazon EC2 instances in a public subnet. The web application uses a MySQL database in a private subnet. The database should be accessible to database administrators.
Which of the following options should the Architect recommend? (Choose two.)
A. Create a bastion host in a public subnet, and use the bastion host to connect to the database.An organization runs an online voting system for a television program. During broadcasts, hundreds of thousands of votes are submitted within minutes and sent to a front-end fleet of auto-scaled Amazon EC2 instances. The EC2 instances push the votes to an RDBMS database. The database is unable to keep up with the front-end connection requests.
What is the MOST efficient and cost-effective way of ensuring that votes are processed in a timely manner?
A. Each front-end node should send votes to an Amazon SQS queue. Provision worker instances to read the SQS queue and process the message information into RDBMS database.Nowadays, the certification exams become more and more important and required by more and more enterprises when applying for a job.
