On-Demand Self-Service Correct Answer: Provision computing capabilities as needed
automatically without requiring human interaction with service provider.
Cloud Computing Correct Answer: Cloud computing is a model for enabling ubiquitous,
convenient, on-demand network access to a shared pool of configurable computing resources
(e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and
released with minimal management effort or service provider interaction. This cloud model is
composed of five essential characteristics, three service models, and four deployment models.
National Institute of Standards and Technology (NIST) Definition in accordance with Special
Publication (SPM 800-145)
Broad Network Access Correct Answer: capabilities available over the network can be accessed
by a wide variety of interface devices using standard mechanisms...
Resource Pooling Correct Answer: The provider's computing resources are pooled to serve
multiple consumers using a multi-tenant model, with different resources dynamically assigned
and reassigned according to consumer demand.
Rapid elasticity Correct Answer: Capabilities can be elastically provisioned and released, in
some cases automatically, to scale rapidly outward and inward with demand. ADD-ON )To the
consumer, the capabilities available for provisioning often appear to be unlimited and can be
appropriated in any quantity at any time.)
Measured Service Correct Answer: Resource usage can be monitored, controlled, and reported,
providing transparency for both the provider and consumer of the utilized service.

High availability systems Correct Answer: Computing environments configured to provide
nearly full-time availability
Such systems typically have redundant hardware and software that makes the system available
despite failures
Well-designed high availability systems avoid having single points-of-failure
Disaster Recovery Correct Answer: The policies, tools and procedures to enable the recovery or
continuation of vital technology infrastructure and systems.
Should indicate key metrics of recovery point objective (RPO) and recovery time objective
(RTO)
