4.5 Explain operational change-control processes during an IT project

Question 1

When describing an information technology (IT) environment, how are terms such as “cloud” or “on-premises” different than a term such as “tiered”?

Answer 1

Cloud and “on-premises” describe where the environment exists, and “tiered” describes how the environment is structured.

Question 2

What is the primary purpose of maintenance windows?

Answer 2

Maintenance windows limit downtime by creating a timebox where multiple teams can perform functions on a system

Question 3

Term for post-production release validations that confirm the production software behaves as expected. The quality assurance (QA) engineer runs these tests to confirm that the release matches the functionality they found during pre-production tests

Answer 3

Release validation check

Question 4

The automated flow of work within a continuous integration/continuous deployment (CI/CD) methodology consists of software development and information technology (IT) operations. What are the four phases of software development?

Answer 4

Plan, code, build, and test

Question 5

A project manager is managing a large complex project with many requirements that will emerge over time. To avoid scope creep, what should the project manager do to approve additional requirements during the project?

Answer 5

Create a solid change control process

Question 6

Creating a solid change control process manages change requests that may affect _________

Answer 6

the project’s requirement

Question 7

During a maintenance window, an information technology (IT) team deploys a new software upgrade and immediately detects a defect that affects system performance. After troubleshooting, the team determines that the defect will require additional time to fix beyond the maintenance window. What should the IT team do at the end of the scheduled maintenance window?

Answer 7

Initiate the rollback plan

Question 8

What type of software approval evaluates whether a software change could have a ripple effect on how the information flows throughout the organization?

Answer 8

Architectural approval

Question 9

The tiered architecture incorporates multiple software environments (or stages) in the DevOps processes. How does tiered architecture protect a project against risk? (Select all that apply.)

• Multitiered environments reduce risk on a project because they combine the user applications and the physical database.
• Multitiered environments reduce risk on a project because it ensures rigorously testing the software before deploying the software.
• Multitiered environments reduce risk on a project because they are simpler than a single-tier architecture.
• Multitiered environments reduce risk on a project by separating development and test operations from the production environment.

Answer 9

• Multitiered environments reduce risk on a project because it ensures rigorously testing the software before deploying the software
• Multitiered environments reduce risk on a project by separating development and test operations from the production environment
