1. What structural concept does 'redundancy' refer to in seismic design of building systems? → Having multiple lateral force-resisting elements so failure of one does not cause collapse
2. Which IBC occupancy group classification applies to a building used primarily for the storage of moderate-hazard combustible materials? → Group S-1
3. Quick Sort selects a 'pivot' element and then: → Partitions elements into those less than and greater than the pivot
4. What is the ICC's 'Group R' occupancy classification used for? → Residential occupancies
5. In high-rise building design under the IBC, at what building height does the code trigger enhanced structural integrity and systems requirements? → 75 feet above the lowest level of fire department vehicle access
6. Which of the following is an ICC certification program? → Certified Building Official (CBO)
7. Under ICC code development, what is the role of a 'code change proposal'? → It is a formal written request to modify ICC model code language
8. How many continuing education hours does ICC typically require for credential renewal over a three-year cycle? → 36 hours
9. In a building permit system, which query optimization technique stores the results of a frequently executed subquery? → Common Table Expression (CTE)
10. What is the primary function of occupancy separation walls required by the IBC between different occupancy groups? → To limit fire spread between areas of differing hazard levels
11. According to the IBC, who is responsible for requesting required inspections? → The owner or the owner's authorized agent
12. Under ICC codes, which hardware standard ensures that exit device (panic bar) installations meet security and egress requirements simultaneously? → UL 305
13. Under the IBC, which document primarily governs the design loads (dead, live, wind, snow, seismic) for building structural systems? → ASCE 7

18. Which entity is responsible for enforcing ICC codes at the local level? → Local building departments
19. In Scrum, how is the length of a sprint typically defined? → It is a fixed time-box, commonly one to four weeks
20. What is the DRY principle in programming? → Dont Repeat Yourself — avoid code duplication
