QUESTION 2
A company\\’s IT Security team needs to ensure that all servers within an Amazon VPC can communicate with a list of
five approved external IPs only. The team also wants to receive a notification every time any server tries to open a
connection with a non-approved endpoint.
What is the MOST cost-effective solution that meets these requirements?
A. Add allowed IPs to the network ACL for the application server subnets. Enable VPC Flow Logs with a filter set to ALL.
Create an Amazon CloudWatch Logs filter on the VPC Flow Logs log group filtered by REJECT. Create an alarm for this
metric to notify the Security team.
B. Enable Amazon GuardDuty on the account and the specific region. Upload a list of allowed IPs to Amazon S3 and
link the S3 object to the GuardDuty trusted IP list. Configure an Amazon CloudWatch Events rule on all GuardDuty
findings to trigger an Amazon SNS notification to the Security team.
C. Add allowed IPs to the network ACL for the application server subnets. Enable VPC Flow Logs with a filter set to
REJECT. Set an Amazon CloudWatch Logs filter for the log group on every event. Create an alarm for this metric to
notify the Security team.

the S3 object to the GuardDuty threat IP list. Integrate GuardDuty with a compatible SIEM to report on every alarm from
GuardDuty.

AWS Certified Data Analytics – Specialty Certification：https://aws.amazon.com/certification/certified-data-analytics-specialty/
[2020.11] Popular Amazon DAS-C01 exam practice questions (1-5)
QUESTION 1
A retail company\\’s data analytics team recently created multiple product sales analysis dashboards for the average
selling price per product using Amazon QuickSight. The dashboards were created from .csv files uploaded to Amazon
S3. The team is now planning to share the dashboards with the respective external product owners by creating
individual users in Amazon QuickSight. For compliance and governance reasons, restricting access is a key
requirement. The product owners should view only their respective product analysis in the dashboard reports.
Which approach should the data analytics team take to allow product owners to view only their products in the
dashboard?
A. Separate the data by product and use S3 bucket policies for authorization.
B. Separate the data by product and use IAM policies for authorization.
C. Create a manifest file with row-level security.
D. Create dataset rules with row-level security.
Correct Answer: B
QUESTION 2
A large company has a central data lake to run analytics across different departments. Each department uses a
separate AWS account and stores its data in an Amazon S3 bucket in that account. Each AWS account uses the AWS
Glue Data Catalog as its data catalog. There are different data lake access requirements based on roles. Associate
analysts should only have read access to their departmental data. Senior data analysts can have access to multiple
departments including theirs, but for a subset of columns only.
Which solution achieves these required access patterns to minimize costs and administrative tasks?
A. Consolidate all AWS accounts into one account. Create different S3 buckets for each department and move all the
data from every account to the central data lake account. Migrate the individual data catalogs into a central data catalog
and apply fine-grained permissions to give to each user the required access to tables and databases in AWS Glue and
Amazon S3.
B. Keep the account structure and the individual AWS Glue catalogs on each account. Add a central data lake account
and use AWS Glue to catalog data from various accounts. Configure cross-account access for AWS Glue crawlers to
scan the data in each departmental S3 bucket to identify the schema and populate the catalog. Add the senior data
analysts into the central account and apply highly detailed access controls in the Data Catalog and Amazon S3.
C. Set up an individual AWS account for the central data lake. Use AWS Lake Formation to catalog the cross-account
locations. On each individual S3 bucket, modify the bucket policy to grant S3 permissions to the Lake Formation service-linked role. Use Lake Formation permissions to add fine-grained access controls to allow senior analysts to view specific
tables and columns.
D. Set up an individual AWS account for the central data lake and configure a central S3 bucket. Use an AWS Lake
Formation blueprint to move the data from the various buckets into the central S3 bucket. On each individual bucket,
modify the bucket policy to grant S3 permissions to the Lake Formation service-linked role. Use Lake Formation
permissions to add fine-grained access controls for both associate and senior analysts to view specific tables and
columns.
Correct Answer: B
QUESTION 3
Once a month, a company receives a 100 MB .csv file compressed with gzip. The file contains 50,000 property listing
records and is stored in Amazon S3 Glacier. The company needs its data analyst to query a subset of the data for a
specific vendor.
What is the most cost-effective solution?
A. Load the data into Amazon S3 and query it with Amazon S3 Select.
B. Query the data from Amazon S3 Glacier directly with Amazon Glacier Select.
C. Load the data to Amazon S3 and query it with Amazon Athena.
D. Load the data to Amazon S3 and query it with Amazon Redshift Spectrum.
Correct Answer: C
Reference: https://aws.amazon.com/athena/faqs/
QUESTION 4
A manufacturing company has been collecting IoT sensor data from devices on its factory floor for a year and is storing
the data in Amazon Redshift for daily analysis. A data analyst has determined that, at an expected ingestion rate of
about 2 TB per day, the cluster will be undersized in less than 4 months. A long-term solution is needed. The data
analyst has indicated that most queries only reference the most recent 13 months of data, yet there are also quarterly
reports that need to query all the data generated from the past 7 years. The chief technology officer (CTO) is concerned
about the costs, administrative effort, and performance of a long-term solution.
Which solution should the data analyst use to meet these requirements?
A. Create a daily job in AWS Glue to UNLOAD records older than 13 months to Amazon S3 and delete those records
from Amazon Redshift. Create an external table in Amazon Redshift to point to the S3 location. Use Amazon Redshift
Spectrum to join data that is older than 13 months.
B. Take a snapshot of the Amazon Redshift cluster. Restore the cluster to a new cluster using dense storage nodes with
additional storage capacity.
C. Execute a CREATE TABLE AS SELECT (CTAS) statement to move records that are older than 13 months to
quarterly partitioned data in Amazon Redshift Spectrum backed by Amazon S3.
D. Unload all the tables in Amazon Redshift to an Amazon S3 bucket using S3 Intelligent-Tiering. Use AWS Glue to
crawl the S3 bucket location to create external tables in an AWS Glue Data Catalog. Create an Amazon EMR cluster
using Auto Scaling for any daily analytics needs, and use Amazon Athena for the quarterly reports, with both using the
same AWS Glue Data Catalog.
Correct Answer: B
QUESTION 5
A financial company uses Apache Hive on Amazon EMR for ad-hoc queries. Users are complaining of sluggish
performance.
A data analyst notes the following:
Approximately 90% of the queries are submitted 1 hour after the market opens. Hadoop Distributed File System (HDFS)
utilization never exceeds 10%.
Which solution would help address the performance issues?
A. Create instance fleet configurations for core and task nodes. Create an automatic scaling policy to scale out the
instance groups based on the Amazon CloudWatch CapacityRemainingGB metric. Create an automatic scaling policy to
scale in the instance fleet based on the CloudWatch CapacityRemainingGB metric.
B. Create instance fleet configurations for core and task nodes. Create an automatic scaling policy to scale out the
instance groups based on the Amazon CloudWatch YARNMemoryAvailablePercentage metric. Create an automatic
scaling policy to scale in the instance fleet based on the CloudWatch YARNMemoryAvailablePercentage metric.
C. Create instance group configurations for core and task nodes. Create an automatic scaling policy to scale out the
instance groups based on the Amazon CloudWatch CapacityRemainingGB metric. Create an automatic scaling policy to
scale in the instance groups based on the CloudWatch CapacityRemainingGB metric.
D. Create instance group configurations for core and task nodes. Create an automatic scaling policy to scale out the
instance groups based on the Amazon CloudWatch YARNMemoryAvailablePercentage metric. Create an automatic
scaling policy to scale in the instance groups based on the CloudWatch YARNMemoryAvailablePercentage metric.
