1. Question 701 · 712 in bank

   Which responsibility belongs to AWS when a company hosts its databases on Amazon EC2 instances?

   • ADatabase backups
   • BDatabase software patches
   • COperating system patches
   • DOperating system installations

   Show answer

   Answer: D

   Explanation

   D. AWS provides the infrastructure and services (like EC2) that include a range of Amazon Machine Images (AMIs) with pre-installed operating systems. This means AWS is responsible for ensuring that these AMIs are available and that the underlying infrastructure to run these instances is secure and reliable. The other responsibilities listed - database backups (A), database software patches (B), and operating system patches (C) - are under the purview of the customer when using Amazon EC2 instances.

   • AAWS Pricing Calculator
   • BAmazon CloudWatch
   • CAWS Cost Explorer
   • DAWS Budgets

   Show answer

   Answer: A

   Explanation

   A. AWS Pricing Calculator: A web-based tool that allows users to estimate the cost of using AWS services. It helps in understanding and estimating the costs associated with various AWS resources based on usage patterns, regions, and other parameters. Users can input their specific requirements to get an estimated monthly cost. B. Amazon CloudWatch: A monitoring and observability service for AWS resources. C. AWS Cost Explorer: A tool within the AWS Management Console that provides visualization and analysis of AWS costs and usage.

6. Question 706 · 712 in bank

   Which of the following is a recommended design principle of the AWS Well-Architected Framework?

   • AReduce downtime by making infrastructure changes infrequently and in large increments.
   • BInvest the time to configure infrastructure manually.
   • CLearn to improve from operational failures.
   • DUse monolithic application design for centralization.

   Show answer

   Answer: C

   Explanation

   A. Reduce downtime by making infrastructure changes infrequently and in large increments: This statement goes against the best practices recommended by the AWS Well-Architected Framework. It's generally recommended to make frequent and smaller changes to infrastructure to reduce the risk of issues and improve overall system agility. B. Invest the time to configure infrastructure manually: The AWS Well-Architected Framework encourages the use of automation to configure and manage infrastructure. Manual configuration is prone to errors, less scalable, and harder to maintain compared to automated approaches. C. Learn to improve from operational failures: This is a key principle of the AWS Well-Architected Framework. It emphasizes the importance of learning from failures and continuously improving the architecture based on operational experiences. This involves implementing mechanisms for monitoring, logging, and analyzing failures to enhance system resilience. D. Use monolithic application design for centralization: The AWS Well-Architected Framework generally favors a microservices architecture over a monolithic design. Microservices promote modularity, scalability, and flexibility.

7. Question 707 · 712 in bank

   Using AWS Identity and Access Management (IAM) to grant access only to the resources needed to perform a task is a concept known as:

   • Arestricted access.
   • Bas-needed access.
   • Cleast privilege access.
   • Dtoken access.

   Show answer

   Answer: C

   Explanation

   A. Restricted access: While the term "restricted access" is used in the context of limiting access, it is not a specific concept associated with IAM in AWS. It doesn't convey the principle of granting the minimum necessary permissions for a task. B. As-needed access: This term is not a standard concept associated with IAM. However, it aligns somewhat with the idea of granting access based on specific needs. C. Least privilege access: Least privilege access means granting users or entities the minimum level of permissions required to perform their tasks, reducing the risk of unintended or malicious actions. D. Token access: "Token access" is not a standard term in the context of AWS IAM. Tokens are often associated with authentication and authorization, but the specific concept of least privilege access is better described by option C.

8. Question 708 · 712 in bank

   Which AWS service or tool can be used to set up a firewall to control traffic going into and coming out of an Amazon VPC subnet?

   • ASecurity group
   • BAWS WAF
   • CAWS Firewall Manager
   • DNetwork ACL

   Show answer

   Answer: D

   Explanation

   A. Security group: Acts as a virtual firewall for an Amazon EC2 instance. It controls inbound and outbound traffic at the instance level. While it's an essential component for controlling traffic to and from EC2 instances, it operates at the instance level, not at the subnet level. B. AWS WAF (Web Application Firewall): Focused on protecting web applications from common web exploits. It is used for filtering HTTP traffic and is not designed to control traffic at the VPC subnet level. C. AWS Firewall Manager: A service that helps manage AWS WAF rules across multiple accounts and resources. It is more about central configuration and management of WAF rules, rather than directly controlling traffic at the VPC subnet level. D. Network ACL (Access Control List): A set of rules that control inbound and outbound traffic at the subnet level. It operates at the network layer (Layer 3) and allows or denies traffic based on defined rules for a specific subnet. Network ACLs provide control over traffic entering and leaving a subnet within an Amazon VPC.

9. Question 709 · 712 in bank

   A company wants to operate a data warehouse to analyze data without managing the data warehouse infrastructure. Which AWS service will meet this requirement?

   • AAmazon Aurora
   • BAmazon Redshift Serverless
   • CAWS Lambda
   • DAmazon RDS

   Show answer

   Answer: B

   Explanation

   A. Amazon Aurora: A relational database engine offered as part of Amazon RDS (Relational Database Service). While it is a high-performance database engine, it is optimized for transactional workloads rather than analytical processing typical of data warehouses. B. Amazon Redshift: A fully managed, petabyte-scale data warehouse service in the cloud. It is specifically designed for analytics and data warehousing, offering fast query performance using SQL queries and integration with various business intelligence tools. C. AWS Lambda: A serverless compute service that allows you to run code without provisioning or managing servers. It is event-driven and primarily used for executing code in response to events, such as changes in data or system state. D. Amazon RDS: A managed relational database service that supports various database engines like MySQL, PostgreSQL, Oracle, SQL Server, and MariaDB. Similar to Amazon Aurora, it is optimized for transactional workloads rather than analytical processing.

    How does AWS Cloud computing help businesses reduce costs? (Choose two.)

    • AAWS charges the same prices for services in every AWS Region.
    • BAWS enables capacity to be adjusted on demand.
    • CAWS offers discounts for Amazon EC2 instances that remain idle for more than 1 week.
    • DAWS does not charge for data sent from the AWS Cloud to the internet.
    • EAWS eliminates many of the costs of building and maintaining on-premises data centers.

    Show answer

    Answer: BE

    Explanation

    B. AWS enables capacity to be adjusted on demand: AWS provides the flexibility to scale resources up or down based on demand. This allows businesses to optimize costs by only paying for the resources they actually use, avoiding unnecessary expenses during periods of lower demand. E. AWS eliminates many of the costs of building and maintaining on-premises data centers: With AWS, businesses can leverage cloud infrastructure without the need to invest in and maintain physical data centers. This eliminates upfront capital expenses, ongoing maintenance costs, and the need to overprovision resources for future growth, leading to significant cost savings. A. AWS charges the same prices for services in every AWS Region: AWS pricing can vary by region based on factors such as infrastructure costs in different regions. C. AWS offers discounts for Amazon EC2 instances that remain idle for more than 1 week: Businesses are billed for the provisioned capacity, whether or not it is actively used. D. AWS does not charge for data sent from the AWS Cloud to the internet: While AWS provides data transfer out allowances, additional data transfer beyond these allowances is subject to charges. .
