Amazon DBS-C01 Quiz 1 Topic 7 Questions 1-5

Question: 1

An Amazon RDS EBS-optimized instance with Provisioned IOPS (PIOPS) storage is using less than half of its allocated IOPS over the course of several hours under constant load. The RDS instance exhibits multi-second read and write latency, and uses all of its maximum bandwidth for read throughput, yet the instance uses less than half of its CPU and RAM resources.

What should a Database Specialist do in this situation to increase performance and return latency to subsecond levels?

AIncrease the size of the DB instance storage

BChange the underlying EBS storage type to General Purpose SSD (gp2)

CDisable EBS optimization on the DB instance

DChange the DB instance to an instance class with a higher maximum bandwidth

Question: 2

A company is closing one of its remote data centers. This site runs a 100 TB on-premises data warehouse

solution. The company plans to use the AWS Schema Conversion Tool (AWS SCT) and AWS DMS for the

migration to AWS. The site network bandwidth is 500 Mbps. A Database Specialist wants to migrate the onpremises data using Amazon S3 as the data lake and Amazon Redshift as the data warehouse. This move must take place during a 2-week period when source systems are shut down for maintenance. The data should stay encrypted at rest and in transit.

Which approach has the least risk and the highest likelihood of a successful data transfer?

ASet up a VPN tunnel for encrypting data over the network from the data center to AWS. Leverage AWS SCT and apply the converted schema to Amazon Redshift. Once complete, start an AWS DMS task to move the data from the source to Amazon S3. Use AWS Glue to load the data from Amazon S3 to Amazon Redshift.

BLeverage AWS SCT and apply the converted schema to Amazon Redshift. Start an AWS DMS task with
two AWS Snowball Edge devices to copy data from on-premises to Amazon S3 with AWS KMS encryption.
Use AWS DMS to finish copying data to Amazon Redshift.

CLeverage AWS SCT and apply the converted schema to Amazon Redshift. Once complete, use a fleet of 10 TB dedicated encrypted drives using the AWS Import/Export feature to copy data from on-premises to Amazon S3 with AWS KMS encryption. Use AWS Glue to load the data to Amazon redshift.

DSet up a VPN tunnel for encrypting data over the network from the data center to AWS. Leverage a native database export feature to export the data and compress the files. Use the aws S3 cp multi-port upload command to upload these files to Amazon S3 with AWS KMS encryption. Once complete, load the data to
Amazon Redshift using AWS Glue.

ACreate an Amazon DynamoDB table with provisioned capacity mode

BCreate an Amazon DocumentDB cluster

CCreate an Amazon DynamoDB table with on-demand capacity mode

DCreate an Amazon Aurora Serverless DB cluster

Question: 4

A company is writing a new survey application to be used with a weekly televised game show. The application will be available for 2 hours each week. The company expects to receive over 500,000 entries every week, with each survey asking 2-3 multiple choice Question:s of each user. A Database Specialist needs to select a platform that is highly scalable for a large number of concurrent writes to handle he anticipated volume.

Which AWS services should the Database Specialist consider? (Choose two.)

AAmazon DynamoDB

BAmazon Redshift

CAmazon Neptune

DAmazon Elasticsearch Service

EAmazon ElastiCache

Question: 5

For the first time, a database professional is establishing a test graph database on Amazon Neptune. The database expert must input millions of rows of test observations from an Amazon S3.csv file. The database professional uploaded the data to the Neptune DB instance through a series of API calls.

Which sequence of actions enables the database professional to upload the data most quickly? (Select three.)

AEnsure Amazon Cognito returns the proper AWS STS tokens to authenticate the Neptune DB instance to the S3 bucket hosting the CSV file.

BEnsure the vertices and edges are specified in different .csv files with proper header column formatting.

CUse AWS DMS to move data from Amazon S3 to the Neptune Loader.

DCurl the S3 URI while inside the Neptune DB instance and then run the addVertex or addEdge commands.

EEnsure an IAM role for the Neptune DB instance is configured with the appropriate permissions to allow access to the file in the S3 bucket.

FCreate an S3 VPC endpoint and issue an HTTP POST to the databases loader endpoint.
