Amazon SAA-C01 Online Questions & Answers

• Question 421:

  A Solutions Architect is designing network architecture for an application that has compliance requirements. The application will be hosted on Amazon EC2 instances in a private subnet and will be using Amazon S3 for storing data. The compliance requirements mandate that the data cannot traverse the public Internet.

  What is the MOST secure way to satisfy this requirement?

  A. Use a NAT Instance.
  B. Use a NAT Gateway.
  C. Use a VPC endpoint.
  D. Use a Virtual Private Gateway.
  C. Use a VPC endpoint.

• Question 422:

  You are designing a multi-platform web application for AWS. The application will run on EC2 instances and will be accessed from PCs. tablets and smart phones Supported accessing platforms are Windows. MACOS. IOS and Android Separate sticky session and SSL certificate setups are required for different platform types which of the following describes the most cost effective and performance efficient architecture setup?

  A. Setup a hybrid architecture to handle session state and SSL certificates on-prem and separate EC2 Instance groups running web applications for different platform types running in a VPC
  B. Set up one ELB for all platforms to distribute load among multiple instance under it Each EC2 instance implements ail functionality for a particular platform.
  C. Set up two ELBs The first ELB handles SSL certificates for all platforms and the second ELB handles session stickiness for all platforms for each ELB run separate EC2 instance groups to handle the web application for each platform.
  D. Assign multiple ELBS to an EC2 instance or group of EC2 instances running the common components of the web application, one ELB for each platform type Session stickiness and SSL termination are done at the ELBs.
  D. Assign multiple ELBS to an EC2 instance or group of EC2 instances running the common components of the web application, one ELB for each platform type Session stickiness and SSL termination are done at the ELBs.

• Question 423:

  You need a persistent and durable storage to trace call activity of an IVR (Interactive Voice Response) system. Call duration is mostly in the 2-3 minutes timeframe. Each traced call can be either active or terminated. An external application needs to know each minute the list of currently active calls, which are usually a few calls/second. Put once per month there is a periodic peak up to 1000 calls/second for a few hours. The system is open 24/7 and any downtime should be avoided. Historical data is periodically archived to files. Cost saving is a priority for this project. What database implementation would better fit this scenario, keeping costs as low as possible?

  A. Use RDS Multi-AZ with two tables, one for -Active calls" and one for -Terminated calls". In this way the "Active calls_ table is always small and effective to access.
  B. Use DynamoDB with a "Calls" table and a Global Secondary Index on a "IsActive'" attribute that is present for active calls only In this way the Global Secondary index is sparse and more effective.
  C. Use DynamoDB with a 'Calls" table and a Global secondary index on a 'State" attribute that can equal to "active" or "terminated" in this way the Global Secondary index can be used for all Items in the table.
  D. Use RDS Multi-AZ with a "CALLS" table and an Indexed "STATE* field that can be equal to 'ACTIVE" or -TERMINATED" In this way the SOL query Is optimized by the use of the Index.
  B. Use DynamoDB with a "Calls" table and a Global Secondary Index on a "IsActive'" attribute that is present for active calls only In this way the Global Secondary index is sparse and more effective.

• Question 424:

  A Solutions Architect needs to design an architecture for a new, mission-critical batch processing billing application. The application is required to run Monday, Wednesday, and Friday from 5 AM to 11 AM. Which is the MOST cost-effective Amazon EC2 pricing model?

  A. Amazon EC2 Spot Instances
  B. On-Demand Amazon EC2 Instances
  C. Scheduled Reserved Instances
  D. Dedicated Amazon EC2 Instances
  C. Scheduled Reserved Instances
