What activities are included in the SDLC Operation/Maintenance Phase?

The correct answer involves monitoring activities as part of the Software Development Life Cycle (SDLC) Operation/Maintenance Phase. This phase focuses on the ongoing monitoring of the system to ensure that it operates as intended and meets operational requirements. Monitoring activities typically include performance tracking, security checks, error detection, and system updates, all of which help ensure system reliability and effectiveness over time.

Engaging in thorough monitoring allows teams to identify potential issues before they escalate, maintain compliance with regulatory requirements, and ensure that the system adapts to evolving user needs and technological changes. By continuously assessing various components of the system, organizations can enhance operational efficiencies and improve user satisfaction.

In contrast, the other choices reflect activities that are not primarily focused on the ongoing operation and maintenance of a system. While implementing or assessing can be part of the broader process during different phases of the SDLC (such as implementation or initial assessments), they are not the central focus during the operation and maintenance phase, which prioritizes the constant vigilance necessary to maintain system performance and security.
