What is the primary purpose of authentication in IT security?
Authentication verifies the identity of a user or device to ensure they are authorized to access a
system.
How does multi-factor authentication (MFA) enhance security?
MFA enhances security by requiring two or more forms of verification, such as something you
know (password), something you have (smartphone), or something you are (biometrics).
What is the difference between single sign-on (SSO) and multi-factor authentication?
SSO allows users to authenticate once and access multiple applications without re-entering
credentials, while MFA requires multiple forms of identification to improve security.
What is a disaster recovery plan (DRP)?
A disaster recovery plan is a set of policies and procedures to restore IT systems and data after a
disruption or disaster.
What is the role of data backup in disaster recovery?
Data backup ensures that copies of critical data are stored safely so that they can be recovered in
the event of a disaster or data loss.
What is the difference between a full backup and an incremental backup?
A full backup copies all data, while an incremental backup only copies data that has changed
since the last backup.
What is a business continuity plan (BCP)?
1
, A business continuity plan outlines strategies for ensuring that essential business functions
continue during and after a disaster.
What are the key components of a disaster recovery plan?
Key components include risk assessment, business impact analysis, recovery strategies, plan
development, testing, and continuous improvement.
What is the 3-2-1 backup strategy?
The 3-2-1 strategy involves having three copies of data, two stored locally on different devices,
and one stored off-site or in the cloud.
How often should a disaster recovery plan be tested?
A disaster recovery plan should be tested regularly, at least annually, to ensure that it works
effectively during an actual disaster.
What is the role of cloud computing in disaster recovery?
Cloud computing enables businesses to store and recover data remotely, offering flexible and
scalable disaster recovery solutions.
What is a recovery point objective (RPO)?
RPO is the maximum acceptable amount of data loss, measured in time, between the last backup
and the point of failure.
What is a recovery time objective (RTO)?
RTO is the maximum acceptable downtime after a disaster, indicating how quickly systems should
be restored to minimize business disruption.
What is the difference between cold, warm, and hot disaster recovery sites?
A cold site has minimal infrastructure and requires time to set up, a warm site has partial
infrastructure and can be ready more quickly, and a hot site is fully operational and ready to use
immediately.
