After launching an instance that you intend to serve as a NAT (Network Address Translation) device in a public subnet you modify your route tables to have the NAT device be the target of internet bound traffic of your private subnet. When you try and make an outbound connection to the internet from an instance in the private subnet, you are not successful. Which of the following steps could resolve the issue?
A. Attaching a second Elastic Network interface to the NAT instance, and placing it in the private subnet
B. Attaching an Elastic IP address to the instance in the private subnet
C. Attaching a second Elastic network interface to the instance in the private subnet, and placing it in the public subnet
D. Disabling the Source/Destination check attribute on the NAT instance
正解：D

A retail company runs hourly flash sales and has a performance issue on its Amazon RDS for PostgreSQL database. The Database Administrators have identified that the issue with performance happens when finance and marketing employees refresh sales dashboards that are used for reporting real-time sales data.
What should be done to resolve the issue without impacting performance?
A. Monitor the database with Amazon CloudWatch and increase the instance $126 as necessary Make no changes to the dashboards
B. Take an hourly snapshot of the RDS PostgreSQL database and load the hourly snapshots to another database to which the dashboards in pointed
C. Move data from tie RDS PostgreSQL database to Amazon Redshift nightly and point the dashboards at Amazon Redshilt
D. Create a Read Replica of the RDS PostgroSQL database and point Hie dashboards at the Read Replica
正解：D

An online retail company has more than 50 million active customers and receives more than 25,000 orders each day. The company collects purchase data for customers and stores this data in Amazon S3. Additional customer data is stored in Amazon RDS.
The company wants to make all the data available to various teams so that the teams can perform analytics.
The solution must provide the ability to manage fine-grained permissions for the data and must minimize operational overhead.
Which solution will meet these requirements?
A. Create a data lake by using AWS Lake Formation. Create an AWS Glue JDBC connection to Amazon RDS. Register the S3 bucket in Lake Formation. Use Lake Formation access controls to limit access.
B. Schedule an AWS Lambda function to periodically copy data from Amazon RDS to Amazon S3. Create an AWS Glue crawler. Use Amazon Athena to query the data. Use S3 policies to limit access.
C. Create an Amazon Redshift cluster. Schedule an AWS Lambda function to periodically copy data from Amazon S3 and Amazon RDS to Amazon Redshift. Use Amazon Redshift access controls to limit access.
D. Migrate the purchase data to write directly to Amazon RDS. Use RDS access controls to limit access.

A company that hosts its web application on AWS wants to ensure all Amazon EC2 instances, Amazon RDS DB instances, and Amazon Redshift clusters are configured with tags. The company wants to minimize the effort of configuring and operating this check.
What should a solutions architect do to accomplish this?
A. Use Cost Explorer to display resources that are not properly tagged. Tag those resources manually.
B. Use AWS Config rules to define and detect resources that are not properly tagged.
C. Write API calls to check all resources for proper tag allocation. Schedule an AWS Lambda function through Amazon CloudWatch to periodically run the code.
D. Write API calls to check all resources for proper tag allocation. Periodically run the code on an EC2 instance.

A company uses an Amazon EMR cluster to process data once a day. The raw data comes from Amazon S3, and the resulting processed data is also stored in Amazon S3. The processing must complete within 4 hours; currently, it only takes 3 hours. However, the processing time is taking 5 to 10 minutes. longer each week due to an increasing volume of raw data.
The team is also concerned about rising costs as the compute capacity increases. The EMR cluster is currently running on three m3 xlarge instances (one master and two core nodes).
Which of the following solutions will reduce costs related to the increasing compute needs?
A. Add additional task nodes, but use instance fleets with the master node in On-Demand mode and a mix of On-Demand and Spot Instances for the core and task nodes. Purchase a standard all-upfront Reserved Instance for the master node.
B. Add additional task nodes, but use instance fleets with the master node in Spot mode and a mix of On- Demand and Spot Instances for the core and task nodes. Purchase enough scheduled Reserved Instances to offset the cost of running any On-Demand instances.
C. Add additional task nodes, but have the team purchase an all-upfront convertible Reserved Instance for each additional node to offset the costs.
D. Add additional task nodes, but use instance fleets with the master node in on-Demand mode and a mix of On-Demand and Spot Instances for the core and task nodes. Purchase a scheduled Reserved Instances for the master node.
