Describe cloud concepts: Describe the benefits of using cloud services

Question 1

What is high availability in cloud services?

Answer 1

High availability ensures maximum uptime and availability, even during disruptions, supported by service-level agreements (SLAs).

Question 2

How much downtime does 99% availability allow per month?

Answer 2

7.2 hours per month.

Question 3

How much downtime does 99.99% availability allow per month?

Answer 3

42.3 minutes per month.

Question 4

What is scalability in cloud services?

Answer 4

Scalability is the ability to adjust resources to meet demand, either by vertical scaling (increasing resource capacity) or horizontal scaling (adding/removing resources).

Question 5

What are the two types of scaling in the cloud?

Answer 5

Vertical scaling and horizontal scaling.

Question 6

What is reliability in the context of cloud computing?

Answer 6

Reliability is the ability of a system to recover from failures and continue functioning.

Question 7

What framework highlights reliability as a key pillar?

Answer 7

The Microsoft Azure Well-Architected Framework.

Question 8

What does performance predictability in the cloud focus on?

Answer 8

It predicts resources needed to deliver a positive customer experience using tools like autoscaling and load balancing.

Question 9

How does the cloud support cost predictability?

Answer 9

By tracking resource use in real time, applying analytics to forecast costs, and using tools like TCO and Pricing Calculators.

Question 10

How does the cloud ensure compliance with corporate and regulatory standards?

Answer 10

By using set templates, updating resources to meet new standards, and flagging non-compliant resources.

Question 11

What cloud models automatically handle patches and updates?

Answer 11

Platform as a Service (PaaS) and Software as a Service (SaaS).

Question 12

Which cloud model provides maximum control over security?

Answer 12

Infrastructure as a Service (IaaS).

Question 13

What does cloud-based auditing provide?

Answer 13

It flags non-compliant resources and offers mitigation strategies.

Question 14

What are the benefits of cloud management?

Answer 14

Automatically scale resource deployment.
Deploy resources using preconfigured templates.
Monitor resource health and replace failing resources.
Receive automatic performance alerts.

Question 15

What tools can be used to manage the cloud environment?

Answer 15

Web portal.
Command-line interface.
APIs.
PowerShell.

Question 16

How does template-based resource deployment improve manageability?

Answer 16

It eliminates the need for manual configuration, speeding up deployment.

Question 17

What is the Total Cost of Ownership (TCO) tool used for in cloud computing?

Answer 17

To estimate potential cloud spend and analyze cost efficiency.

Question 18

What role does autoscaling play in the cloud?

Answer 18

It adjusts resources automatically based on real-time demand, improving performance and cost-efficiency.

Question 19

What are some examples of metrics for configuring cloud alerts?

Answer 19

CPU usage, memory utilization, and application response times.

Question 20

How does the Microsoft Azure Well-Architected Framework assist cloud users?

Answer 20

It provides best practices for designing reliable, secure, and efficient cloud solutions.
