Amazon BDS-C00 Online Questions & Answers

  • Question 151:

    You have written a server-side Node.js application and a web application with an HTML/JavaScript front end that uses the Angular.js Framework. The server-side application connects to an Amazon Redshift cluster, issue queries, and then returns the results to the front end for display. Your user base is very large and distributed, but it is important to keep the cost of running this application low.

    Which deployment strategy is both technically valid and the most cost-effective?

    A. Deploy an AWS Elastic Beanstalk application with two environments: one for the Node.js application and another for the web front end. Launch an Amazon Redshift cluster, and point your application to its Java Database connectivity (JDBC) endpoint
    B. Deploy an AWS OpsWorks stack with three layers: a static web server layer for your front end, a Node.js app server layer for your server-side application, and a Redshift DB layer Amazon Redshift cluster
    C. Upload the HTML, CSS, images, and JavaScript for the front end to an Amazon Simple Storage Service (S3) bucket. Create an Amazon CloudFront distribution with this bucket as its origin. Use AWS Elastic Beanstalk to deploy the Node.js application. Launch an Amazon Redshift cluster, and point your application to its JDBC endpoint
    D. Upload the HTML, CSS, images, and JavaScript for the front end, plus the Node.js code for the server-side application, to an Amazon S3 bucket. Create a CloudFront distribution with this bucket as its origin. Launch an Amazon Redshift cluster, and point your application to its JDBC endpoint
    E. Upload the HTML, CSS, images, and JavaScript for the front end to an Amazon S3 bucket. Use AWS Elastic Beanstalk to deploy the Node.js application. Launch an Amazon Redshift cluster, and point your application to its JDBC endpoint

  • Question 152:

    A customer is collecting clickstream data using Amazon Kinesis and is grouping the events by IP address into 5-minute chunks stored in Amazon S3.

    Many analysts in the company use Hive on Amazon EMR to analyze this data. Their queries always reference a single IP address. Data must be optimized for querying based on IP address using Hive running on Amazon EMR.

    What is the most efficient method to query the data with Hive?

    A. Store an index of the files by IP address in the Amazon DynamoDB metadata store for EMRFS.
    B. Store the Amazon S3 objects with the following naming scheme: bucket_name/source=ip_address/year=yy/month=mm/day=dd/hour=hh/filename.
    C. Store the data in an HBase table with the IP address as the row key.
    D. Store the events for an IP address as a single file in Amazon S3 and add metadata with keys: Hive_Partitioned_IPAddress.

  • Question 153:

    To help you manage your Amazon EC2 instances, images, and other Amazon EC2 resources, you can assign your own metadata to each resource in the form of____________

    A. special filters
    B. functions
    C. tags
    D. wildcards

  • Question 154:

    You have been asked to use your department's existing continuous integration (CI) tool to test a three- tier web architecture defined in an AWS CloudFormation template. The tool already supports AWS APIs and can launch new AWS CloudFormation stacks after polling version control. The CI tool reports on the success of the AWS CloudFormation stack creation by using the DescribeStacks API to look for the CREATE_COMPLETE status.

    The architecture tiers defined in the template consist of:

    1.

    One load balancer

    2.

    Five Amazon EC2 instances running the web application

    3.

    One multi-AZ Amazon RDS instance How would you implement this? Choose 2 answers

    A. Define a WaitCondition and a WaitConditionhandle for the output of a output of a UserData command that does sanity checking of the application's post-install state
    B. Define a CustomResource and write a script that runs architecture-level integration tests through the load balancer to the application and database for the state of multiple tiers
    C. Define a WaitCondition and use a WaitConditionHandle that leverages the AWS SDK to run the DescribeStacks API call until the CREATE_COMPLETE status is returned
    D. Define a CustomResource that leverages the AWS SDK to run the DescribeStacks API call until the CREATE_COMPLETE status is returned
    E. Define a UserDataHandle for the output of a UserData command that does sanity checking of the application's post-install state and runs integration tests on the state of multiple tiers through load balancer to the application
    F. Define a UserDataHandle for the output of a CustomResource that does sanity checking of the application's post-install state

  • Question 155:

    What does Amazon EBS stand for?

    A. Elastic Block Storage
    B. Elastic Business Server
    C. Elastic Blade Server
    D. Elastic Block Store

  • Question 156:

    A travel website needs to present a graphical quantitative summary of its daily bookings to website visitors for marketing purposes. The website has millions of visitors per day, but wants to control costs by implementing the least-expensive solution for this visualization.

    What is the most cost-effective solution?

    A. Generate a static graph with a transient EMR cluster daily, and store in an Amazon S3.
    B. Generate a graph using MicroStrategy backed by a transient EMR cluster.
    C. Implement a Jupyter front-end provided by a continuously running EMR cluster leveraging spot instances for task nodes.
    D. Implement a Zeppelin application that runs on a long-running EMR cluster.

  • Question 157:

    If I want my instance to run on a single-tenant hardware, which value do I have to set the instance's tenancy attribute to?

    A. dedicated
    B. isolated
    C. one
    D. reserved

  • Question 158:

    You have a load balancer configured for VPC, and all backend Amazon EC2 instances are in service. However, your web browser times out when connecting to the load balancer's DNS name. Which options are probable causes of this behavior?

    A. The load balancer was not configured to use a public subnet with an Internet gateway configured
    B. The Amazon EC2 instances do not have a dynamically allocated private IP address
    C. The security groups or network ACLs are not properly configured for web traffic
    D. The load balancer is not configured in a private subnet with a NAT instance
    E. The VPC does not have a VGW configured

  • Question 159:

    A real-time bidding company is rebuilding their monolithic application and is focusing on serving real-time data. A large number of reads and writes are generated from thousands of concurrent users who follow items and bid on the company's

    sale offers.

    The company is experiencing high latency during special event spikes, with millions of concurrent users.

    The company needs to analyze and aggregate a part of the data in near real time to feed an internal dashboard.

    What is the BEST approach for serving and analyzing data, considering the constraint of the row latency on the highly demanded data?

    A. Use Amazon Aurora with Multi Availability Zone and read replicas. Use Amazon ElastiCache in front of the read replicas to serve read-only content quickly. Use the same database as datasource for the dashboard.
    B. Use Amazon DynamoDB to store real-time data with Amazon DynamoDB. Accelerator to serve content quickly. use Amazon DynamoDB Streams to replay all changes to the table, process and stream to Amazon Elasti search Service with AWS Lambda.
    C. Use Amazon RDS with Multi Availability Zone. Provisioned IOPS EBS volume for storage. Enable up to five read replicas to serve read-only content quickly. Use Amazon EMR with Sqoop to import Amazon RDS data into HDFS for analysis.
    D. Use Amazon Redshift with a DC2 node type and a multi-mode cluster. Create an Amazon EC2 instance with pgpoo1 installed. Create an Amazon ElastiCache cluster and route read requests through pgpoo1, and use Amazon Redshift for analysis.

  • Question 160:
