✍️ Sample CIS Questions & Answers
1. Which baseline document should a CIS implementation specialist reference when evaluating whether a requested change is within scope?
The Scope Baseline, comprising the scope statement, WBS, and WBS dictionary, is the reference for evaluating scope changes.
2. What is the critical path in a CIS implementation project schedule?
The critical path is the longest sequence of dependent activities and directly determines the earliest possible project completion date.
3. In CIS integration design, what is an API (Application Programming Interface) PRIMARILY used for?
An API defines the rules and protocols for how different software applications communicate and share data with each other.
4. A CIS specialist is asked to reduce the load on a production server that handles high concurrent user traffic. Which strategy is MOST effective?
Load balancing distributes incoming traffic across multiple servers, preventing any single server from becoming a bottleneck under high concurrent usage.
5. What is the role of a reverse proxy in CIS web application infrastructure?
A reverse proxy intercepts client requests and forwards them to appropriate backend servers, often handling SSL termination, caching, and load distribution.
6. What is the purpose of environment promotion in a CIS implementation (Dev → QA → UAT → Production)?
Environment promotion ensures that code and configuration changes are tested and validated at each stage before reaching production, reducing the risk of defects affecting end users.
