Question 20

A Sysops administrator configured AWS Backup to capture snapshots from a single Amazon EC2 instance that has one Amazon Elastic Block Store (Amazon EBS) volume attached. On the first snapshot, the EBS volume has 10 GiB of data. On the second snapshot, the EBS volume still contains 10 GiB of data, but 4 GiB have changed. On the third snapshot, 2 GiB of data have been added to the volume, for a total of 12 GiB.

How much total storage is required to store these snapshots?

Options:

12 GiB

16 GiB

26 GiB

32 GiB

Question 21

A company hosts an online shopping portal in the AWS Cloud. The portal provides HTTPS security by using a TLS certificate on an Elastic Load Balancer (ELB). Recently, the portal suffered an outage because the TLS certificate expired. A SysOps administrator must create a solution to automatically renew certificates to avoid this issue in the future.

What is the MOST operationally efficient solution that meets these requirements?

Options:

Request a public certificate by using AWS Certificate Manager (ACM). Associate the certificate from ACM with the ELB. Write a scheduled AWS Lambda function to renew the certificate every 18 months.

Request a public certificate by using AWS Certificate Manager (ACM). Associate the certificate from ACM with the ELB. ACM will automatically manage the renewal of the certificate.

Register a certificate with a third-party certificate authority (CA). Import this certificate into AWS Certificate Manager (ACM). Associate the certificate from ACM with the ELB. ACM will automatically manage the renewal of the certificate.

Register a certificate with a third-party certificate authority (CA). Configure the ELB to import the certificate directly from the CA. Set the certificate refresh cycle on the ELB to refresh when the certificate is within 3 months of the expiration date.

Same here. I've heard mixed reviews about using exam dumps, but for us, it definitely paid off.

Mariam

Do anyone think Cramkey questions can help improve exam scores?

Katie (not set)

Absolutely! Many people have reported improved scores after using Cramkey Dumps, and there are also success stories of people passing exams on the first try. I already passed this exam. I confirmed above questions were in exam.

Joey

I highly recommend Cramkey Dumps to anyone preparing for the certification exam. They have all the key information you need and the questions are very similar to what you'll see on the actual exam.

Dexter (not set)

Agreed. It's definitely worth checking out if you're looking for a comprehensive and reliable study resource.

Question 22

A company is running a serverless application on AWS Lambda 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

What should a SysOps administrator do to resolve these errors'?

Options:

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

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

Increase the value in the max_connect_errors parameter in the parameter group that the database uses

Update the Lambda function's reserved concurrency to a higher value

Question 23

A company uses an Amazon Elastic File System (Amazon EFS) file system to share files across many Linux Amazon EC2 instances. A SysOps administrator notices that the file system's PercentIOLimit metric is consistently at 100% for 15 minutes or longer. The SysOps administrator also notices that the application that reads and writes to that file system is performing poorly. They application requires high throughput and IOPS while accessing the file system.

What should the SysOps administrator do to remediate the consistently high PercentIOLimit metric?

Options:

Create a new EFS file system that uses Max I/O performance mode. Use AWS DataSync to migrate data to the new EFS file system.

Create an EFS lifecycle policy to transition future files to the Infrequent Access (IA) storage class to improve performance. Use AWS DataSync to migrate existing data to IA storage.

Modify the existing EFS file system and activate Max I/O performance mode.

Modify the existing EFS file system and activate Provisioned Throughput mode.
