Read the first 7 Cloud Computing Fundamentals flashcards as text

  1. Which AWS tool helps estimate the monthly cost of an AWS solution before deployment?

    Answer: AWS Pricing Calculator

    The AWS Pricing Calculator lets you model your architecture and generate a cost estimate before you commit to any services.

  2. What is the concept of 'fault tolerance' in cloud architecture?

    Answer: The ability of a system to continue operating even if one or more components fail

    Fault tolerance means a system remains operational without interruption even when individual components experience failures.

  3. Which of the following is an example of vertical scaling (scaling up) in AWS?

    Answer: Switching from a t3.medium to a t3.2xlarge instance type

    Vertical scaling means increasing the power of an existing resource, such as changing to a larger instance type with more CPU and RAM.

  4. What does the term 'multi-tenant' mean in public cloud environments?

    Answer: Multiple customers share the same underlying physical infrastructure

    Multi-tenancy means multiple customers' workloads run on shared physical hardware, with logical isolation provided by virtualization.

  5. Which AWS service would you use to send automated email and SMS notifications triggered by AWS events?

    Answer: Amazon SNS

    Amazon SNS (Simple Notification Service) is a pub/sub messaging service that can fan out notifications via email, SMS, HTTP, and other protocols.

  6. What is a key advantage of using managed services like Amazon RDS compared to self-managed databases on EC2?

    Answer: AWS handles routine tasks like backups, patching, and failover automatically

    Managed services like RDS offload undifferentiated heavy lifting (patching, backups, replication) to AWS so teams can focus on their applications.

  7. Which of the following is a characteristic of the 'measured service' cloud computing property defined by NIST?

    Answer: Resource usage is monitored, controlled, and billed based on consumption

    Measured service means cloud systems automatically monitor and report resource usage, enabling transparent, usage-based billing for customers.
