Question 1:

A Big Data analytics company wants to set up an AWS cloud architecture that throttles requests in case of sudden traffic spikes. The company is looking for AWS services that can be used for buffering or throttling to handle such traffic variations.

Which of the following services can be used to support this requirement?

Amazon SQS, Amazon SNS and AWS Lambda

Amazon API Gateway, Amazon SQS and Amazon Kinesis

Amazon Gateway Endpoints, Amazon SQS and Amazon Kinesis

Elastic Load Balancer, Amazon SQS, AWS Lambda

Question 2:

The DevOps team at an e-commerce company wants to perform some maintenance work on a specific EC2 instance that is part of an Auto Scaling group using a step scaling policy. The team is facing a maintenance challenge - every time the team deploys a maintenance patch, the instance health check status shows as out of service for a few minutes. This causes the Auto Scaling group to provision another replacement instance immediately.

As a solutions architect, which are the MOST time/resource efficient steps that you would recommend so that the maintenance work can be completed at the earliest? (Select two)

Put the instance into the Standby state and then update the instance by applying the maintenance patch. Once the instance is ready, you can exit the Standby state and then return the instance to service

Suspend the ReplaceUnhealthy process type for the Auto Scaling group and apply the maintenance patch to the instance. Once the instance is ready, you can manually set the instance's health status back to healthy and activate the ReplaceUnhealthy process type again

Suspend the ScheduledActions process type for the Auto Scaling group and apply the maintenance patch to the instance. Once the instance is ready, you can you can manually set the instance's health status back to healthy and activate the ScheduledActions process type again

Take a snapshot of the instance, create a new AMI and then launch a new instance using this AMI. Apply the maintenance patch to this new instance and then add it back to the Auto Scaling Group by using the manual scaling policy. Terminate the earlier instance that had the maintenance issue

Delete the Auto Scaling group and apply the maintenance fix to the given instance. Create a new Auto Scaling group and add all the instances again using the manual scaling policy

Question 3:

The flagship application for a gaming company connects to an Amazon Aurora database and the entire technology stack is currently deployed in the United States. Now, the company has plans to expand to Europe and Asia for its operations. It needs the games table to be accessible globally but needs the users and games_played tables to be regional only.

How would you implement this with minimal application refactoring?

Use a DynamoDB global table for the games table and use Amazon Aurora for the users and games_played tables

Use an Amazon Aurora Global Database for the games table and use DynamoDB tables for the users and games_played tables

Use an Amazon Aurora Global Database for the games table and use Amazon Aurora for the users and games_played tables

Use a DynamoDB global table for the games table and use DynamoDB tables for the users and games_played tables

Question 4:

The solo founder at a tech startup has just created a brand new AWS account. The founder has provisioned an EC2 instance 1A which is running in region A. Later, he takes a snapshot of the instance 1A and then creates a new AMI in region A from this snapshot. This AMI is then copied into another region B. The founder provisions an instance 1B in region B using this new AMI in region B.

At this point in time, what entities exist in region B?

1 EC2 instance, 1 AMI and 1 snapshot exist in region B

1 EC2 instance and 1 AMI exist in region B

1 EC2 instance and 2 AMIs exist in region B

1 EC2 instance and 1 snapshot exist in region B

Question 5:

A financial services company recently launched an initiative to improve the security of its AWS resources and it had enabled AWS Shield Advanced across multiple AWS accounts owned by the company. Upon analysis, the company has found that the costs incurred are much higher than expected.

Which of the following would you attribute as the underlying reason for the unexpectedly high costs for AWS Shield Advanced service?

AWS Shield Advanced is being used for custom servers, that are not part of AWS Cloud, thereby resulting in increased costs

Savings Plans has not been enabled for the AWS Shield Advanced service across all the AWS accounts

AWS Shield Advanced also covers AWS Shield Standard plan, thereby resulting in increased costs

Consolidated billing has not been enabled. All the AWS accounts should fall under a single consolidated billing for the monthly fee to be charged only once

Question 6:

A leading video streaming service delivers billions of hours of content from Amazon S3 to customers around the world. Amazon S3 also serves as the data lake for its big data analytics solution. The data lake has a staging zone where intermediary query results are kept only for 24 hours. These results are also heavily referenced by other parts of the analytics pipeline.

Which of the following is the MOST cost-effective strategy for storing this intermediary query data?

Store the intermediary query results in S3 One Zone-Infrequent Access storage class

Store the intermediary query results in S3 Standard storage class

Store the intermediary query results in S3 Standard-Infrequent Access storage class

Store the intermediary query results in S3 Glacier Instant Retrieval storage class

Question 7:

A software engineering intern at an e-commerce company is documenting the process flow to provision EC2 instances via the Amazon EC2 API. These instances are to be used for an internal application that processes HR payroll data. He wants to highlight those volume types that cannot be used as a boot volume.

Can you help the intern by identifying those storage volume types that CANNOT be used as boot volumes while creating the instances? (Select two)

Cold HDD (sc1)

Instance Store

Throughput Optimized HDD (st1)

Provisioned IOPS SSD (io1)

General Purpose SSD (gp2)

Question 8:

The payroll department at a company initiates several computationally intensive workloads on EC2 instances at a designated hour on the last day of every month. The payroll department has noticed a trend of severe performance lag during this hour. The engineering team has figured out a solution by using Auto Scaling Group for these EC2 instances and making sure that 10 EC2 instances are available during this peak usage hour. For normal operations only 2 EC2 instances are enough to cater to the workload.

As a solutions architect, which of the following steps would you recommend to implement the solution?

Configure your Auto Scaling group by creating a scheduled action that kicks-off at the designated hour on the last day of the month. Set the min count as well as the max count of instances to 10. This causes the scale-out to happen before peak traffic kicks in at the designated hour

Configure your Auto Scaling group by creating a simple tracking policy and setting the instance count to 10 at the designated hour. This causes the scale-out to happen before peak traffic kicks in at the designated hour

Configure your Auto Scaling group by creating a scheduled action that kicks-off at the designated hour on the last day of the month. Set the desired capacity of instances to 10. This causes the scale-out to happen before peak traffic kicks in at the designated hour

Configure your Auto Scaling group by creating a target tracking policy and setting the instance count to 10 at the designated hour. This causes the scale-out to happen before peak traffic kicks in at the designated hour

Question 9:

Which of the following features of an Amazon S3 bucket can only be suspended once they have been enabled?

Versioning

Server Access Logging

Static Website Hosting

Requester Pays

Question 10:

A new DevOps engineer has just joined a development team and wants to understand the replication capabilities for RDS Multi-AZ as well as RDS Read-replicas.

Which of the following correctly summarizes these capabilities for the given database?

Multi-AZ follows asynchronous replication and spans at least two Availability Zones within a single region. Read replicas follow asynchronous replication and can be within an Availability Zone, Cross-AZ, or Cross-Region

Multi-AZ follows asynchronous replication and spans at least two Availability Zones within a single region. Read replicas follow synchronous replication and can be within an Availability Zone, Cross-AZ, or Cross-Region

Multi-AZ follows synchronous replication and spans at least two Availability Zones within a single region. Read replicas follow asynchronous replication and can be within an Availability Zone, Cross-AZ, or Cross-Region

Multi-AZ follows asynchronous replication and spans one Availability Zone within a single region. Read replicas follow synchronous replication and can be within an Availability Zone, Cross-AZ, or Cross-Region
