You weigh the pros and cons of various technologies based on the requirements you are given. The decision you make is to go with Direct Connect. Which option best describes the features Direct Connect provides?

Answer:

A private, dedicated network connection between your facilities and AWS Question 2: Several S3 Buckets have been deleted and a few EC2 instances have been terminated. Which AWS service can you use to determine who took these actions?

Answer:

AWS CloudTrail Question 3: Your application team stores critical data within a third-party SaaS cloud vendor.The data comes from an internal application that runs on Amazon ECS Fargate, which then stores the data within Amazon S3 in a proprietary format. Currently, AWS Lambda functions are triggered via Amazon S3 event notifications to trigger the transfer of data to a SaaS application.Due to resource and time limits, you are exploring other means of completing this workflow of transferring data from AWS to the SaaS solution. Which AWS service offers the most efficiency and has the least operational overhead?

Answer:

Amazon AppFlow Question 4: You are designing an architecture that will house an Auto Scaling group of EC2 instances. The application hosted on the instances is expected to be extremely popular.Forecasts for traffic to this site predict very high traffic, and you will need a load balancer to handle tens of millions of requests per second while maintaining high throughput at ultra-low latency. You need to select the correct type of load balancer to front your Auto Scaling group to meet this high traffic requirement. Which load balancer should you select?

Answer:

You will need a Network Load Balancer to meet this requirement.Question 5: You work for an online retailer where any downtime at all can cause a significant loss of revenue. You have architected your application to be deployed on an Auto Scaling Group of EC2 instances behind a load balancer. You have configured and deployed these resources using a CloudFormation template. The Auto Scaling Group is configured with default settings and a simple CPU utilization scaling policy. You have also set up multiple Availability Zones for high availability. The load balancer does health checks against an HTML file generated by script. When you begin performing load testing on your application and notice in CloudWatch that the load balancer is not sending traffic to one of your EC2 instances. What could be the problem?

Answer:

The EC2 instance has failed the load balancer health check.Question 6: You are managing data storage for your company, and there are many EBS volumes. Your management team has given you some new requirements. Certain metrics on the EBS volumes need to be monitored, and the database team needs to be notified by email when certain metric thresholds are exceeded. Which AWS services can be configured to meet these requirements?

Answer:

• SNS
• CloudWatch

Question 7: Jennifer is a cloud engineer for her application team. The application leverages several third-party SaaS vendors to complete their workflows within the application. Currently, the team uses numerous AWS Lambda functions for each SaaS vendor that run daily to connect to the configured vendor. The functions initiate a transfer of data files, ranging from one megabyte up to 80 gibibytes in size. These data files are stored in an Amazon S3 bucket and then referenced by the application itself. The data transfer routinely fails due to execution timeout limits in the Lambda functions, and the team wants to find a simpler and less error-prone way of transferring the required data. Which solution or AWS service could be the best fit for their solution?

Answer:

Amazon AppFlow Question 8: You work for an Australian company, who are currently being audited and need some compliance reports regarding your applications that are hosted on AWS. Specifically, they need a Australian Hosting Certification Framework - Strategic Certification certificate. You need to get this as quickly as possible. What should you do?

Answer:

Use AWS Artifact to download the certificate Question 9: A new startup company decides to use AWS to host their web application. They configure a VPC as well as two subnets within the VPC. They also attach an internet gateway to the VPC. In the first subnet, they create the EC2 instance which will host their web application.They finish the configuration by making the application accessible from the Internet. The second subnet hosts their database and they don't want the database accessible from the Internet. Which statement best describes this scenario?

Answer:

The web server is in a public subnet, and the database server is in a private subnet. The public subnet has a route to the internet gateway in the route table.Question 10: An Application Load Balancer is fronting an Auto Scaling Group of EC2 instances, and the instances are backed by an RDS database. The Auto Scaling Group has been configured to use the Default Termination Policy. You are testing the Auto Scaling Group and have triggered a scale-in. Which instance will be terminated first?

Answer:

The instance launched from the oldest launch configuration Question 11: You have landed your dream job at Amazon and are moving to the Alexa team. You will be tasked with product design and improvement. You meet a new colleague who does not come from a tech background, and they would like to know what services make up the Alexa service. Select the correct services.

Answer:

• Amazon Transcribe
• Amazon Polly
• Amazon Lex

Question 12: You have joined a newly formed software company as a Solutions Architect. It is a small company, and you are the only employee with AWS experience. The owner has asked for your recommendations to ensure that the AWS resources are deployed to proactively remain within budget. Which AWS service can you use to help ensure you don't have cost overruns for your AWS resources?

Answer:

AWS Budgets Question 13: You have recently migrated your small company to AWS and are looking for some general best practice guidance within the platform. Which AWS service can help you optimize your AWS environment by giving recommendations to reduce cost, increase performance, and improve security?

Answer:

AWS Trusted Advisor Question 14: An organization of about 100 employees has performed the initial setup of users in IAM. All users except administrators have the same basic privileges. But now it has been determined that 50 employees will have extra restrictions on EC2. They will be unable to launch new instances or alter the state of existing instances. What will be the quickest way to implement these restrictions?

Answer:

Create the appropriate policy. Create a new group for the restricted users. Place the restricted users in the new group and attach the policy to the group Question 15: Your company needs to shift an application to the cloud. You are looking for a solution to collect, process, gain immediate insight, and then transfer the application data to AWS. Part of this effort also includes moving a large data warehouse into AWS. The warehouse is 50TB, and it would take over a month to migrate the data using the current bandwidth available. What is the best option available to perform this one time migration considering both cost and performance aspects?

Answer:

AWS Snowball Edge Question 16: You have a typical architecture for an Application Load Balancer fronting an Auto Scaling group of EC2 instances, backed by an RDS MySQL database. Your Application Load Balancer is performing health checks on the EC2 instances. What actions will be taken if an instance fails these health checks?

Answer:

The ALB stops sending traffic to the instance.
