Amazon AWS Certified Solutions Architect - Professional (SAP-C02) Sample Questions (Q38-Q43):

NEW QUESTION # 38
A Solutions Architect is building a solution for updating user metadata that is initiated by web servers. The solution needs to rapidly scale from hundreds to tens of thousands of jobs in less than 30 seconds. The solution must be asynchronous always avertable and minimize costs.
Which strategies should the Solutions Architect use to meet these requirements?

A. Create an AWS Lambda function that will update user metadata.
Create an Amazon SOS queue and configure it as an event source for the Lambda function.
Update the web application to send jobs to the queue.
B. Create an Amazon SQS queue.
Create an AMI with a worker to check the queue and update user metadata.
Configure an Amazon EC2 Auto Scaling group with the new AMI.
Update the web application to send jobs to the queue.
C. Create an AWS SWF worker that will update user metadata updating web application to start a new workflow for every job.
D. Create an AWS Lambda function that will update user metadata.
Create AWS Step Functions that will trigger the Lambda function.
Update the web application to initiate Step Functions for every job.

Answer: A

Explanation:
It will be easier to scale with Lambda using SQS as an event source as per the requirement than it is with EC2 Auto scaling.

NEW QUESTION # 39
A retail company has a small ecommerce web application that uses an Amazon RDS for PostgreSQL DB instance. The DB instance is deployed with the Multi-AZ option turned on.

The company expects a surge in users for an upcoming version and wants to optimize the design for scalability and performance.
Which solution will meet these requirements?

A. Keep the leaderboard data in the RDS DB instance. Provision a Multi-AZ deployment of an Amazon ElastiCache for Redis cluster.
B. Add a read-only replica to the RDS DB instance. Add an RDS Proxy database proxy.
C. Stream the leaderboard data by using Amazon Kinesis Data Firehose with an Amazon S3 bucket as the destination. Query the S3 bucket by using Amazon Athena for the leaderboard.
D. Migrate the database to Amazon DynamoDB. Store the leader different tables. Use Apache HiveQL JOIN statements to build the leaderboard

Answer: C

NEW QUESTION # 41
A solutions architect must provide a secure way for a team of cloud engineers to use the AWS CLI to upload objects into an Amazon S3 bucket Each cloud engineer has an IAM user. IAM access keys and a virtual multi- factor authentication (MFA) device The IAM users for the cloud engineers are in a group that is named S3- access The cloud engineers must use MFA to perform any actions in Amazon S3 Which solution will meet these requirements?

A. Attach a policy to the S3-access group to deny all S3 actions unless MFA is present Request temporary credentials from AWS Security Token Service (AWS STS) Attach the temporary credentials in a profile that Amazon S3 will reference when the user performs actions in Amazon S3
B. Update the trust policy for the S3-access group to require principals to use MFA when principals assume the group Use 1AM access keys with the AWS CLI to call Amazon S3
C. Attach a policy to the S3-access group to deny all S3 actions unless MFA is present Use 1AM access keys with the AWS CLI to call Amazon S3
D. Attach a policy to the S3 bucket to prompt the 1AM user for an MFA code when the 1AM user performs actions on the S3 bucket Use 1AM access keys with the AWS CLI tocall Amazon S3

Answer: A

Explanation:
The company should attach a policy to the S3-access group to deny all S3 actions unless MFA is present. The company should request temporary credentials from AWS Security Token Service (AWS STS). The company should attach the temporary credentials in a profile that Amazon S3 will reference when the user performs actions in Amazon S3. This solution will meet the requirements because AWS STS is a service that enables you to request temporary, limited-privilege credentials for IAM users or for users that you authenticate (federated users). You can use MFA with AWS STS to provide an extra layer of security when requesting temporary credentials1. You can use the sts get-session-token AWS CLI command to request temporary credentials that include an MFA token2. You can then use these credentials with the AWS CLI to access Amazon S3 resources. To do this, you need to attach a policy to the IAM group that denies all S3 actions unless MFA is present3.You also need to create a profile in the AWS CLI configuration file that references the temporary credentials.
The other options are not correct because:
Attaching a policy to the S3 bucket to prompt the IAM user for an MFA code when the IAM user performs actions on the S3 bucket would not work because policies attached to S3 buckets cannot enforce MFA authentication. Policies attached to S3 buckets are resource-based policies that define what actions can be performed on the bucket and by whom. They do not have any logic to prompt for an MFA code or verify it.
Updating the trust policy for the S3-access group to require principals to use MFA when principals assume the group would not work because trust policies are used for roles, not groups. Trust policies are policies that define which principals can assume a role. They do not apply to groups, which are collections of IAM users that share permissions.
Creating an Amazon Route 53 Resolver DNS Firewall domain list that contains the allowed domains and configuring a DNS Firewall rule group with rules to allow or block requests based on the domain list would not help with enforcing MFA authentication for Amazon S3 actions. Amazon Route 53 Resolver DNS Firewall is a feature that enables you to filter and regulate outbound DNS traffic for your VPC. You can create reusable collections of filtering rules in DNS Firewall rule groups and associate them with your VPCs.
You can specify lists of domain names to allow or block, and you can customize the responses for the DNS queries that you block. This feature is useful for controlling access to sites and blocking DNS-level threats, but not for requiring MFA authentication.

NEW QUESTION # 42
A company is migrating an application to the AWS Cloud. The application runs in an on-premises data center and writes thousands of images into a mounted NFS file system each night After the company migrates the application, the company will host the application on an Amazon EC2 instance with a mounted Amazon Elastic File System (Amazon EFS) file system.
The company has established an AWS Direct Connect connection to AWS Before the migration cutover. a solutions architect must build a process that will replicate the newly created on-premises images to the EFS file system What is the MOST operationally efficient way to replicate the images?

A. Configure a periodic process to run the aws s3 sync command from the on-premises file system to Amazon S3 Configure an AWS Lambda function to process event notifications from Amazon S3 and copy the images from Amazon S3 to the EFS file system
B. Deploy an AWS DataSync agent to an on-premises server that has access to the NFS file system Send data over the Direct Connect connection to an S3 bucket by using a public VIF Configure an AWS Lambda function to process event notifications from Amazon S3 and copy the images from Amazon S3 to the EFS file system
C. Deploy an AWS DataSync agent to an on-premises server that has access to the NFS file system Send data over the Direct Connect connection to an AWS PrivateLink interface VPC endpoint for Amazon EFS by using a private VIF Configure a DataSync scheduled task to send the images to the EFS file system every 24 hours.
D. Deploy an AWS Storage Gateway file gateway with an NFS mount point. Mount the file gateway file system on the on-premises server. Configure a process to periodically copy the images to the mount point
