Read the first 7 Microsoft 365 Fundamentals Cloud Computing Concepts flashcards as text

  1. Which cloud deployment model is dedicated exclusively to a single organization and may be hosted on-premises or by a third party?

    Answer: Private cloud

    A private cloud is operated solely for one organization, providing greater control and security compared to a public cloud.

  2. What is the primary reason Microsoft 365 services can achieve higher availability than most on-premises solutions?

    Answer: Microsoft distributes workloads across multiple global data centers

    Microsoft 365 leverages a globally distributed network of data centers with redundancy, enabling high availability that most on-premises setups cannot match.

  3. In cloud computing, what does 'agility' refer to?

    Answer: The ability to rapidly provision and deprovision IT resources

    Cloud agility means organizations can quickly spin up or remove IT resources to respond to changing business needs.

  4. Which of the following describes a 'consumption-based' pricing model in cloud computing?

    Answer: Paying only for the resources you actually use

    Consumption-based pricing means customers are billed only for the compute, storage, or services they actually consume.

  5. Which Microsoft 365 component is classified as a cloud-based identity service?

    Answer: Azure Active Directory (Microsoft Entra ID)

    Azure Active Directory (now Microsoft Entra ID) is Microsoft's cloud-based identity and access management service used by Microsoft 365.

  6. What is a key advantage of geo-distribution in Microsoft 365?

    Answer: It ensures data and services are available closer to users worldwide, reducing latency

    Geo-distribution places Microsoft 365 resources in data centers around the world, lowering latency and improving performance for global users.

  7. A company's cloud application automatically provisions additional servers when CPU usage exceeds 80% and removes them when usage drops below 30%. This is an example of:

    Answer: Auto-scaling (elasticity)

    Auto-scaling, a form of elasticity, automatically adjusts resource capacity in response to real-time demand metrics.
