CIS CIS Technical Architecture & Infrastructure 1 — Questions and Answers
Question 1: In a CIS implementation, a Software-as-a-Service (SaaS) deployment model means:
- The client hosts the software on their own servers
- The vendor hosts and manages the software, and the client accesses it over the internet (Correct answer)
- The client purchases a perpetual software license
- The software is deployed on client-owned hardware in a colocation facility
Correct answer: The vendor hosts and manages the software, and the client accesses it over the internet
SaaS delivers software over the internet on a subscription basis, with the vendor responsible for hosting, maintenance, updates, and infrastructure management.
Question 2: What is the purpose of a system architecture diagram in a CIS implementation?
- To document user training schedules
- To visually represent system components, integrations, and data flows (Correct answer)
- To track project budget expenditures
- To record user acceptance test results
Correct answer: To visually represent system components, integrations, and data flows
A system architecture diagram provides a visual overview of all system components, how they connect, and how data flows between them, serving as a key reference for developers and architects.
Question 3: Which infrastructure component distributes incoming network traffic across multiple servers to ensure high availability in a CIS implementation?
- Firewall
- Load balancer (Correct answer)
- Domain controller
- API gateway
Correct answer: Load balancer
A load balancer distributes incoming requests across multiple servers, preventing any single server from being overwhelmed and ensuring continuous availability.
Question 4: In CIS technical architecture, what does 'scalability' refer to?
- The system's ability to maintain security as users increase
- The system's ability to handle growing workloads by adding resources without performance degradation (Correct answer)
- The ability to integrate with legacy systems
- The ease with which administrators can configure user roles
Correct answer: The system's ability to handle growing workloads by adding resources without performance degradation
Scalability describes how well a system can grow to handle increased load, either by adding more resources (scaling out) or upgrading existing ones (scaling up).
Question 5: What is a 'sandbox' environment in the context of CIS technical infrastructure?
- A production backup environment
- An isolated environment used for development, testing, and experimentation without affecting production (Correct answer)
- A secure vault for storing encryption keys
- A network segment reserved for executive users
Correct answer: An isolated environment used for development, testing, and experimentation without affecting production
A sandbox environment is a safe, isolated copy of the system where developers and testers can experiment, build, and test changes without any risk to the live production environment.
Question 6: In a CIS infrastructure design, what is the primary function of a Content Delivery Network (CDN)?
- To centralize all database writes to a single node
- To cache and serve static content from servers geographically close to the user, improving performance (Correct answer)
- To route authentication requests to an identity provider
- To monitor server health and trigger alerts
Correct answer: To cache and serve static content from servers geographically close to the user, improving performance
A CDN caches static assets (images, scripts, stylesheets) at edge nodes worldwide so users receive content from the nearest location, reducing latency and improving load times.
