Chapter 1 AWS Practioner

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

• Multiregional presence

• Highly experienced team of security engineers

• Deep experience in the retail sphere

• Metered, pay-per-use pricing

Which of the following are signs of a highly available application? (Select Two)

• A failure in one georegion will trigger an autofailover in different region

• Applications are protected behind multiple layers of security

• Virtualized hypervisor-driven systems are deployed as company policy

• Spikes in user demand are met through automatically increasing resources

How does the metered payment model make many benefits of cloud computing possible? (select Two)

• 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 capex

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

• Fast resource provisioning & launching

• Efficient (high-density) use of resources

• Greater application security

• Elastic application design

What is hypervisor?

• Hardware device providing an interface between storage & compute modules

• Hardware device providing an interface between networking & compute modules

• Software used to log & monitor virtualized operations

• Software used to administrate virtualized resources run on physical infra

Which of the following best describes server virtualization?

• "Sharding" data from multiple sources into a single virtual data store

• Logically partitioning compute & storage devices into multiple viritual devices

• Aggregating physical resources spread multiple physical devices into single

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

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

• Services that hide infrastructure complexity behind a simple interface

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

• Services give you direct control over underlying compute& storage resources

• Platforms that allow developers to run their code for short periods on

Which of the following best describes Platform as a service products?

• Services that hide infrastructure complexity behind a simple interface

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

• Services giving direct control over underlying compute & storage resources

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

Which of the following best describes SaaS products?

• Services giving direct control over underlying compute & storage resources

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

• Services that hide infrastructure complexity behind a simple interface

• Platforms allowing you to run their code over short periods on cloud server

Which of the following best describes scalability?

• allowing app to automatically add preconfigured compute resources to meet demand

• Allowing app to increase or decrease compute resources to match demand

• Allowing more densely pack virtualized resources onto a single server

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