Question 1

An organization currently runs a large Hadoop environment in their data center and is in the process of creating an alternative Hadoop environment on AWS, using Amazon EMR.

They generate around 20 TB of data on a monthly basis. Also on a monthly basis, files need to be grouped and copied to Amazon S3 to be used for the Amazon EMR environment. They have multiple S3 buckets across AWS accounts to which data needs to be copied. There is a 10G AWS Direct Connect setup between their data center and AWS, and the network team has agreed to allocate

AUse an offline copy method, such as an AWS Snowball device, to copy and transfer data to Amazon S3.

BConfigure a multipart upload for Amazon S3 on AWS Java SDK to transfer data over AWS Direct Connect.

CUse Amazon S3 transfer acceleration capability to transfer data to Amazon S3 over AWS Direct Connect.

DSetup S3DistCop tool on the on-premises Hadoop environment to transfer data to Amazon S3 over AWS Direct Connect.

Answer : D

Question 2

A user has created an ELB with Auto Scaling. Which of the below mentioned offerings from ELB helps the user to stop sending new requests traffic from the load balancer to the EC2 instance when the instance is being deregistered while continuing in-flight requests?

AELB sticky session

BELB deregistration check

CELB connection draining

DELB auto registration Off

Answer : C

Question 3

A new algorithm has been written in Python to identify SPAM e-mails. The algorithm analyzes the free text contained within a sample set of 1 million e-mails stored on Amazon S3. The algorithm must be scaled across a production of 5 PB, which also resides in Amazon S3 storage

Which AWS service strategy is best for this use case?

ACopy the data into Amazon ElasticCache to perform text analysis on the in-memory data and export the results of the model into Amazon machine learning

BUse Amazon EMR to parallelize the text analysis tasks across the cluster using a streaming program step

CUse Amazon Elasticsearch service to store the text and then use the Python Elastic search client to run analysis against the text index

DInitiate a python job from AWS Data pipeline to run directly against the Amazon S3 text files

Answer : C

Question 4

A medical record filing system for a government medical fund is using an Amazon S3 bucket to archive documents related to patients. Every patient visit to a physician creates a new file, which can add up to millions of files each month. Collection of these files from each physician is handled via a batch process that runs every night using AWS Data Pipeline. This is sensitive data, so the data and any associated metadata must be encrypted at rest.

Auditors review some files on a quarterly basis to see whether the records are maintained according to regulations. Auditors must be able to locate any physical file in the S3 bucket or a given data, patient, or physician. Auditors spend a signification amount of time locating such files.

What is the most cost-and time-efficient collection methodology in this situation?

AUse Amazon kinesis to get the data feeds directly from physician, batch them using a Spark application on Amazon Elastic MapReduce (EMR) and then store them in Amazon S3 with folders separated per physician.

BUse Amazon API Gateway to get the data feeds directly from physicians, batch them using a Spark application on Amazon Elastic MapReduce (EMR), and then store them in Amazon S3 with folders separated per physician.

CUse Amazon S3 event notifications to populate an Amazon DynamoDB table with metadata about every file loaded to Amazon S3, and partition them based on the month and year of the file.

DUse Amazon S3 event notifications to populate and Amazon Redshift table with metadata about every file loaded to Amazon S3, and partition them based on the month and year of the file.

Answer : C

Question 5

What does the "Server Side Encryption" option on Amazon S3 provide?

AIt provides an encrypted virtual disk in the Cloud.

BIt doesn't exist for Amazon S3, but only for Amazon EC2.

CIt encrypts the files that you send to Amazon S3, on the server side.

DIt allows to upload files using an SSL endpoint, for a secure transfer.

Answer : A

What is one key difference between an Amazon EBS-backed and an instance-store backed instance?

AAmazon EBS-backed instances can be stopped and restarted

BInstance-store backed instances can be stopped and restarted

CAuto scaling requires using Amazon EBS-backed instances

DVirtual Private Cloud requires EBS backed instances
