In CIS implementations, API rate limiting is used to:
Answer: Control the number of API requests a client can make in a given time period to protect system stability
Rate limiting prevents any single client from overwhelming an API with too many requests, protecting the system's availability and performance for all users.
What is the purpose of a technical specification document in a CIS implementation?
Answer: To describe how a system or component will be built technically, including architecture, data models, and APIs
A technical specification translates business requirements into detailed technical guidance for developers, specifying architecture, data models, interfaces, and implementation approaches.
In CIS architecture, a microservices approach differs from a monolithic architecture in that:
Answer: Microservices decompose the application into small, independently deployable services
Microservices architecture breaks an application into small, loosely coupled services that can be developed, deployed, and scaled independently, improving flexibility and resilience.
Which type of testing validates that a CIS system can handle the expected number of concurrent users without performance degradation?
Answer: Load testing
Load testing simulates realistic user concurrency levels to verify that the system performs acceptably under expected production traffic volumes.
What is the role of a reverse proxy in CIS web application infrastructure?
Answer: To sit in front of web servers, handling client requests, SSL termination, and routing to backend services
A reverse proxy intercepts client requests and forwards them to appropriate backend servers, often handling SSL termination, caching, and load distribution.
During a CIS implementation, a 'configuration management database' (CMDB) is used to:
Answer: Maintain a record of all IT assets, their configurations, and their relationships to each other
A CMDB is a repository that stores information about hardware, software, and network assets along with their configurations and interdependencies, supporting IT service management.
