Chapter 1. The Cloud

Question 1 of 12

1

Which of the following does not contribute significantly to the operational value of a large cloud provider like AWS?

Select one of the following:

  • Multi-regional presence

  • Highly experience teams of security engineers

  • Deep experience in the retail sphere

  • Metered, pay-per-user pricing

Explanation

Question 2 of 12

1

Which of the following are sings of a highly available application? (Select TWO)

Select one or more of the following:

  • A failure in one geographic region will trigger an automatic failover to resources in a different region.

  • Applications are protected behind multiple layers of security.

  • Virtualized hypervisor-driven systems are deployed as mandated by company policy.

  • Spikes in user demand are met through automatically increasing resources.

Explanation

Question 3 of 12

1

How does the metered payment model make many benefits of cloud computing possible? (Select TWO.)

Select one or more of the following:

  • Greater application security is now possible.

  • Experiments with multiple configuration options are now cost-effective.

  • Applications are now highly scalable.

  • Full-stack applications are possible without the need to invest in capital expenses.

Explanation

Question 4 of 12

1

Which of the following are direct benefits of server virtualization? (Select TWO.)

Select one or more of the following:

  • Fast resource provisioning and launching

  • Efficient (high-density) use of resources

  • Greater application security

  • Elastic application designs

Explanation

Question 5 of 12

1

What is a hypervisor?

Select one of the following:

  • Hardware device used to provide an interface between storage and compute modules

  • Hardware device used to provide an interface between networking and compute modules

  • Software used to log and monitor virtualized operations

  • Software used to administrate virtualized resources run on physical infrastructure

Explanation

Question 6 of 12

1

Which of the following best describes server virtualization?

Select one of the following:

  • “Sharding” data from multiple sources into a single virtual data store

  • Logically partitioning physical compute and storage devices into multiple smaller virtual devices

  • Aggregating physical resources spread over multiple physical devices into a single virtual device

  • Abstracting the complexity of physical infrastructure behind a simple web interface

Explanation

Question 7 of 12

1

Which of the following best describes Infrastructure as a Service products?

Select one of the following:

  • Services that hide infrastructure complexity behind a simple interface

  • Services that provide a service to end users through a public network

  • Services that give you direct control over underlying compute and storage resources

  • Platforms that allow developers to run their code over short periods on cloud servers

Explanation

Question 10 of 12

1

Which of the following best describes scalability?

Select one of the following:

  • The ability of an application to automatically add preconfigured compute resources to meet increasing demand

  • The ability of an application to increase or decrease compute resources to match changing demand

  • The ability to more densely pack virtualized resources onto a single physical server

  • The ability to bill resource usage using a pay-per-user model

Explanation

Question 11 of 12

1

Which of the following best describes elasticity?

Select one of the following:

  • The ability to bill resource usage using a pay-per-user model

  • The ability of an application to increase or decrease compute resources to match changing demand

  • The ability of an application to automatically add preconfigured compute resources to meet increasing demand

Explanation

Question 12 of 12

1

Which of the following characteristics most help AWS provide such scalable services? (Select TWO.)

Select one or more of the following:

  • The enormous number of servers it operates

  • The value of its capitalized assets

  • Its geographic reach

  • Its highly automated infrastructure administration systems
