Which of the following best describes how DaaS (Data as a Service) is used by organisations, along with one benefit and one drawback it provides for organisations and their stakeholders?

DaaS allows organisations to access and manage data via cloud services, offering scalability as a benefit but raising data security concerns as a drawback.

DaaS is a hardware-based solution for data storage, providing cost savings but limiting data accessibility.

DaaS is used for internal data processing only, with no impact on stakeholders outside the organisation.

DaaS eliminates the need for data management, ensuring complete data privacy for all stakeholders.

Cloud sourcing and cloud portability have implications for which of the following groups?

Both service providers and organisations (subscribers)

Only organisations (subscribers)

Neither service providers nor organisations (subscribers)

Ensuring digital environments are resilient is important because:

It protects organisations and stakeholders from disruptions and potential losses.

It increases the cost of operations significantly.

It reduces the need for cybersecurity measures.

It eliminates the need for stakeholder engagement.

Which of the following are methods used to improve the resilience of digital environments?

Data back-up and recovery procedures

Which of the following is a benefit and a drawback of methods used to improve the resilience of digital environments?

Increased security and higher costs
