Terry Diab has an experience of 6 years as a cloud security engineer. She recently joined a multinational company as a senior cloud security engineer. Terry learned that there is a high probability that her organizational applications could be hacked and user data such as passwords, usernames, and account information can be exploited by an attacker. The organizational applications have not yet been hacked, but this issue requires urgent action. Therefore, Terry, along with her team, released a software update that is designed to resolve this problem instantly with a quick-release procedure. Terry successfully fixed the problem (bug) in the software product immediately without following the normal quality assurance procedures. Terry's team resolved the problem immediately on the live system with zero downtime for users. Based on the given information, which of the following type of update was implemented by Terry?

  1. Patch
  2. Rollback
  3. Hotfix
  4. Version update

Answer(s): C

Explanation:

A hotfix is a type of update that is used to address a specific issue or bug in a software product. It is typically released quickly and outside of the normal release schedule to resolve problems that are deemed too urgent to wait for the next regular update.

1. Urgent Release: Terry's team released a software update urgently, which is characteristic of a hotfix.

2.
Immediate Fix: The update was designed to resolve the problem instantly, which aligns with the purpose of a hotfix.

3.
Bypassing Normal Procedures: Hotfixes are often released without following the normal quality assurance procedures due to the urgency of the fix.

4. Zero Downtime: The problem was resolved on the live system with zero downtime, which is a critical aspect of hotfix deployment.


Reference:

Hotfixes are used in the software industry to quickly patch issues that could potentially lead to security vulnerabilities or significant disruptions in service. They are applied to live systems, often without requiring a restart, to ensure continuous operation while the issue is being addressed.
