Question: 2

An Amazon S3 Inventory report reveals that more than 1 million objects in an S3 bucket are not encrypted.

These objects must be encrypted, and all future objects must be encrypted at the time they are written.

Which combination of actions should a SysOps administrator take to meet these requirements? (Choose two.)

ACreate an AWS Config rule that runs evaluations against configuration changes to the S3 bucket. When an unencrypted object is found, run an AWS Systems Manager Automation document to encrypt the object in place.

BEdit the properties of the S3 bucket to enable default server-side encryption.

CFilter the S3 Inventory report by using S3 Select to find all objects that are not encrypted. Create an S3 Batch Operations job to copy each object in place with encryption enabled.

DFilter the S3 Inventory report by using S3 Select to find all objects that are not encrypted. Send each object name as a message to an Amazon Simple Queue Service (Amazon SQS) queue. Use the SQS queue to invoke an AWS Lambda function to tag each object with a key of 'Encryption' and a value of 'SSE-KMS'.

EUse S3 Event Notifications to invoke an AWS Lambda function on all new object-created events for the S3 bucket. Configure the Lambda function to check whether the object is encrypted and to run an AWS Systems Manager Automation document to encrypt the object in place when an unencrypted object is found.

Question: 3

A instances at all times to support all traffic. A SysOps administrator must design a highly available, fault-tolerant architecture that continually supports all traffic if one Availability Zone becomes unavailable.

Which configuration meets these requirements?

BDeploy an Auto Scaling group across two Availability Zones with a minimum capacity of four instances.

CDeploy an Auto Scaling group across three Availability Zones with a minimum capacity of four instances.

DDeploy an Auto Scaling group across three Availability Zones with a minimum capacity of six instances.

Question: 4

A company is running a serverless application on AWS Lambd

a. The application stores data in an Amazon

RDS for MySQL DB instance. Usage has steadily increased, and recently there have been numerous "too many connections" errors when the Lambda function attempts to connect to the database. The company already has configured the database to use the maximum max_connections value that is possible.

ACreate a read replica of the database. Use Amazon Route 53 to create a weighted DNS record that
contains both databases.

BUse Amazon RDS Proxy to create a proxy. Update the connection string in the Lambda function.

CIncrease the value in the max_connect_errors parameter in the parameter group that the database uses.

DUpdate the Lambda function's reserved concurrency to a higher value.

A company is tunning a website on Amazon EC2 instances thai are in an Auto Scaling group When the website traffic increases, additional instances lake several minutes to become available because ot a long-running user data script that installs software A SysOps administrator must decrease the time that is required (or new instances to become available

Which action should the SysOps administrator take to meet this requirement?

AReduce the scaling thresholds so that instances are added before traffic increases

BPurchase Reserved Instances to cover 100% of the maximum capacity of the Auto Scaling group

CUpdate the Auto Scaling group to launch instances that have a storage optimized instance type

DUse EC2 Image Builder to prepare an Amazon Machine Image (AMI) that has pre-installed software
