CLF-C02 EXAMINATION SET 2026 SOLVED
QUESTIONS GRADED A+
● Main AWS Cloud value proposition. Answer: Trade upfront cost for
variable cost; benefit from economies of scale; stop guessing capacity;
increase speed and agility; go global quickly
● CapEx vs OpEx. Answer: CapEx is upfront capital spend; OpEx is
ongoing operating expense (cloud shifts more cost to OpEx)
● Elasticity vs scalability. Answer: Elasticity adjusts resources
automatically with demand; scalability is the ability to grow capacity to
meet demand
● High availability (HA). Answer: Design so a system remains
available even when components fail (often using multiple AZs)
● Fault tolerance. Answer: Ability to keep operating with no
interruption when a component fails (more stringent than HA)
● Disaster recovery (DR). Answer: Strategies to restore systems after a
major outage (backup/restore, pilot light, warm standby, multi-site)
, ● AWS global infrastructure components. Answer: Regions, Availability
Zones, and edge locations
● Region vs Availability Zone. Answer: A Region is a geographic area;
an AZ is one or more discrete data centers within a Region
● Edge location purpose. Answer: Deliver content to users with low
latency (used by services like CloudFront)
● Local Zones (what/why). Answer: AWS infrastructure placed near
large population centers for low-latency workloads
● Wavelength (what/why). Answer: AWS infrastructure in 5G networks
for ultra-low latency mobile/edge apps
● Outposts (what/why). Answer: AWS-managed infrastructure installed
on-premises for hybrid workloads
● IaaS vs PaaS vs SaaS. Answer: IaaS gives infrastructure; PaaS gives a
managed platform; SaaS gives a complete application
● Public vs private vs hybrid cloud. Answer: Public uses shared
provider infrastructure; private is dedicated; hybrid combines on-prem
and cloud
