A company plans to set up a cloud infrastructure in AWS. In the planning, it was discussed that you need to deploy two EC2 instances that should continuously run for three years. The CPU utilization of the EC2 instances is also expected to be stable and predictable.
Which is the most cost-efficient Amazon EC2 Pricing type that is most appropriate for this scenario?

A Solutions Architect is unable to connect to the newly deployed EC2 instance via SSH using a home computer. However, the Architect was able to successfully access other existing instances in the VPC without any issues.
Which of the following should the Architect check and possibly correct to restore connectivity?

A Solutions Architect needs to deploy a mobile application that can collect votes for a popular singing competition. Millions of users from around the world will submit votes using their mobile phones. These votes must be collected and stored in a highly scalable and highly available data store which will be queried for realtime ranking.

Which of the following combination of services should the architect use to meet this requirement?

A media company recently launched their newly created web application. Many users tried to visit the website, but they are receiving a 503 Service Unavailable Error. The system administrator tracked the EC2 instance status and saw the capacity is reaching its maximum limit and unable to process all the requests. To gain insights from the application's data, they need to launch a real-time analytics service.

Which of the following allows you to read records in batches?

The media company that you are working for has a video transcoding application running on Amazon EC2. Each EC2 instance polls a queue to find out which video should be transcoded, and then runs a transcoding process. If this process is interrupted, the video will be transcoded by another instance based on the queuing system. This application has a large backlog of videos which need to be transcoded. Your manager would like to reduce this backlog by adding more EC2 instances, however, these instances are only needed until the backlog is reduced.
In this scenario, which type of Amazon EC2 instance is the most cost-effective type to use?

A company has an On-Demand EC2 instance located in a subnet in AWS that hosts a web application.
The security group attached to this EC2 instance has the following Inbound Rules:

The Route table attached to the VPC is shown below. You can establish an SSH connection into the EC2 instance
from the Internet. However, you are not able to connect to the web server using your Chrome browser.

（含图）

Which of the below steps would resolve the issue?

A company is hosting EC2 instances that are on non-production environment and processing non-priority
batch loads, which can be interrupted at any time.
What is the best instance purchasing option which can be applied to your EC2 instances in this case?

A manufacturing company has EC2 instances running in AWS. The EC2 instances are configured with Auto Scaling. There are a lot of requests being lost because of too much load on the servers. The Auto Scaling is launching new EC2 instances to take the load accordingly yet, there are still some requests that are being lost.
Which of the following is the MOST suitable solution that you should implement to avoid losing recently submitted requests?

A travel company has a suite of web applications hosted in an Auto Scaling group of On-Demand EC2 instances behind an Application Load Balancer that handles traffic from various web domains such as i- lovemanila.com, i-love-boracay.com, i-love-cebu.com and many others. To improve security and lessen the overall cost, you are instructed to secure the system by allowing multiple domains to serve SSL traffic without the need to reauthenticate and reprovision your certificate everytime you add a new domain. This migration from HTTP to HTTPS will help improve their SEO and Google search ranking. Which of the following is the most costeffective solution to meet the above requirement?

A new online banking platform has been re-designed to have a microservices architecture in which complex applications are decomposed into smaller, independent services. The new platform is using Docker considering that application containers are optimal for running small, decoupled services. The new solution should remove the need to provision and manage servers, let you specify and pay for resources per application, and improve security through application isolation by design. Which of the following is the MOST suitable service to use to migrate this new platform to AWS?

A company has established a dedicated network connection from its on-premises data center to AWS Cloud using AWS Direct Connect (DX). The core network services, such as the Domain Name System (DNS) service and Active Directory services, are all hosted on-premises. The company has new AWS accounts that will also require consistent and dedicated access to these network services. Which of the following can satisfy this requirement with the LEAST amount of operational overhead and in a cost- effective manner?

A company is storing its financial reports and regulatory documents in an Amazon S3 bucket. To comply with the IT audit, they tasked their Solutions Architect to track all new objects added to the bucket as well as the removed ones. It should also track whether a versioned object is permanently deleted. The Architect must configure Amazon S3 to publish notifications for these events to a queue for post-processing and to an Amazon SNS topic that will notify the Operations team.
Which of the following is the MOST suitable solution that the Architect should implement?

A data analytics company is setting up an innovative checkout-free grocery store. Their Solutions Architect developed a real-time monitoring application that uses smart sensors to collect the items that the customers are getting from the grocery's refrigerators and shelves then automatically deduct it from their accounts. The company wants to analyze the items that are frequently being bought and store the results in S3 for durable storage to determine the purchase behavior of its customers. What service must be used to easily capture, transform, and load streaming data into Amazon S3, Amazon Elasticsearch Service, and Splunk?

A tech startup is launching an on-demand food delivery platform using Amazon ECS cluster with an AWS Fargate serverless compute engine and Amazon Aurora. It is expected that the database read queries will significantly increase in the coming weeks ahead. A Solutions Architect recently launched two Read Replicas to the database cluster to improve the platform's scalability. Which of the following is the MOST suitable configuration that the Architect should implement to load balance all of the incoming read requests equally to the two Read Replicas?

A company is using multiple AWS accounts that are consolidated using AWS Organizations. They want to copy several S3 objects to another S3 bucket that belonged to a different AWS account which they also own. The Solutions Architect was instructed to set up the necessary permissions for this task and to ensure that the destination account owns the copied objects and not the account it was sent from. How can the Architect accomplish this requirement?

A document sharing website is using AWS as its cloud infrastructure. Free users can upload a total of 5 GB data while premium users can upload as much as 5 TB. Their application uploads the user files, which can have a max file size of 1 TB, to an S3 Bucket. In this scenario, what is the best way for the application to upload the large files in S3?

A solutions architect is formulating a strategy for a startup that needs to transfer 50 TB of on-premises data to Amazon S3. The startup has a slow network transfer speed between its data center and AWS which causes a bottleneck for data migration.

Which of the following should the solutions architect implement?

A global online sports betting company has its popular web application hosted in AWS. They are planning to develop a new online portal for their new business venture and they hired you to implement the cloud architecture for a new online portal that will accept bets globally for world sports.
