1/10 · Cloud Technology and Services
A company serves images, style sheets and scripts to a worldwide audience from a single Amazon S3 bucket. Visitors on other continents report that pages take several seconds to appear. Which AWS service is designed to improve this?
AAmazon Route 53
BAmazon CloudFront
CElastic Load Balancing
DS3 Transfer Acceleration
Show answer & explanation
B is correct. Task Statement 3.2 lists the benefits of edge locations. The Amazon CloudFront developer guide states that CloudFront 'speeds up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users,' that it 'delivers your content through a worldwide network of data centers called edge locations,' and that 'the request is routed to the edge location that provides the lowest latency.' It adds that reliability improves because copies of the files are held in multiple edge locations around the world.

2/10 · Security and Compliance
A company runs a web application on Amazon EC2 instances. A critical vulnerability is announced in the Linux distribution that the instances run. Under the AWS shared responsibility model, who is responsible for applying the fix to those instances?
AAWS patches the infrastructure layer, and that covers the instances running on it.
BAWS patches the operating system published in the Amazon Machine Image.
CThe customer patches custom images; AWS patches the images it publishes.
DThe customer patches the guest operating system and the software on the instance.
Show answer & explanation
D is correct. Task Statement 2.1 asks candidates to describe the customer's responsibilities. The AWS shared responsibility model page divides the model into AWS security 'of' the cloud and customer security 'in' the cloud, and states under shared controls for patch management that 'AWS is responsible for patching and fixing flaws within the infrastructure,' while customers 'are responsible for patching their guest OS and applications.' The same page calls out Amazon EC2 as an example where the customer performs guest OS updates and security patching.

3/10 · Cloud Concepts
A European media company has signed distribution deals for Asia and South America. Under its current model it would have to lease space, ship hardware and hire local staff in each market before a single viewer could be served. Which statement about the AWS global infrastructure is accurate?
AAWS copies a workload into the other Regions once it runs in one of them.
BThe workload can be deployed into Regions on those continents within minutes.
CEdge locations can run the company's own application servers near viewers.
DAWS assigns each workload to the Region closest to its audience.
Show answer & explanation
B is correct. Task Statement 1.1 covers the benefits of global infrastructure. 'Six advantages of cloud computing' in the AWS Overview whitepaper lists 'Go global in minutes: Easily deploy your application in multiple regions around the world with just a few clicks... you can provide lower latency and a better experience for your customers at minimal cost.' The Amazon EC2 'Regions and Zones' page supplies the counterpoints the distractors rest on: 'Regions are isolated from each other, and we don't automatically replicate resources across Regions,' and it is the customer who selects the Region in which resources run.

4/10 · Billing, Pricing, and Support
A finance analyst reviewing an invoice asks where the Reserved Instances that the company bought last quarter appear in the list of running resources. What should the analyst be told?
AThey appear as a separate fleet of instances that runs alongside the On-Demand fleet and must be started manually.
BThey do not appear as resources; a Reserved Instance is a billing discount applied to matching usage.
CThey appear while the reservation is unused, and disappear from the list once matching usage consumes them.
DThey appear as reserved capacity blocks in each Availability Zone of the Region where they were purchased.
Show answer & explanation
B is correct. Task Statement 4.1 asks candidates to describe Reserved Instance behavior. The Amazon EC2 'Reserved Instances overview' page states that 'Reserved Instances are not physical instances, but rather a billing discount applied to the use of On-Demand Instances in your account. These On-Demand Instances must match certain attributes, such as instance type and Region, to benefit from the billing discount.' The same page describes the scope distinction between Regional and zonal Reserved Instances that option D misstates.

5/10 · Cloud Technology and Services
A team runs containers on its own servers with an open-source orchestrator that has a large community of add-ons. Its deployment manifests and those community add-ons must keep working unchanged after a move to AWS, and the team no longer wants to operate the orchestrator's control plane itself. Which service should it choose?
AAmazon EKS
BAmazon ECS
CAmazon ECR
DAWS Fargate
Show answer & explanation
A is correct. Task Statement 3.3 asks candidates to recognize the appropriate use of various container options. The Amazon EKS user guide states that 'AWS manages the Kubernetes control plane when you create a cluster with EKS' and that 'Amazon EKS is certified Kubernetes-conformant, so you can deploy Kubernetes-compatible applications without refactoring and use Kubernetes community tooling and plugins.' The Amazon ECS developer guide describes ECS as 'a fully managed container orchestration service' with its own layers of capacity, controller and provisioning, which is the distinction being tested.

6/10 · Security and Compliance
An auditor asks a company to set out which security duties AWS carries for the services the company consumes. Which duty belongs to AWS under the shared responsibility model?
AProtecting the hardware, networking and facilities that the services run on.
BConfiguring the databases and applications that run on an instance.
CSetting the rules on the security group firewall around an instance.
DWatching API activity in the account and reporting calls that look wrong.
Show answer & explanation
A is correct. Task Statement 2.1 asks candidates to describe AWS responsibilities. The AWS shared responsibility model page states that AWS 'is responsible for protecting the infrastructure that runs all of the services offered in the AWS Cloud' and that this infrastructure 'is composed of the hardware, software, networking, and facilities that run AWS Cloud services'. On the other side it states that customers who deploy an Amazon EC2 instance are responsible for 'the configuration of the AWS-provided firewall (called a security group) on each instance', that under Configuration Management 'AWS maintains the configuration of its infrastructure devices, but a customer is responsible for configuring their own guest operating systems, databases, and applications', and that customers are responsible for 'managing their data (including encryption options), classifying their assets, and using IAM tools to apply the appropriate permissions'.

7/10 · Cloud Concepts
A finance director asks why the hourly rate AWS charges for a server is lower than the effective hourly cost the company reaches when it buys equivalent hardware itself. Which explanation does AWS give for this effect?
AUsage aggregated from hundreds of thousands of customers gives a lower variable cost than one company can reach.
BHardware in AWS data centers is depreciated over a longer accounting period than most companies can use.
CCustomers are billed for the capacity they forecast at the start of each year, ending over-purchasing.
DWorkloads are placed on shared hardware and isolated single-tenant capacity is no longer offered.
Show answer & explanation
A is correct. Task Statement 1.4 names economies of scale explicitly. 'Six advantages of cloud computing' states: 'Benefit from massive economies of scale - By using cloud computing, you can achieve a lower variable cost than you can get on your own. Because usage from hundreds of thousands of customers is aggregated in the cloud, providers such as AWS can achieve higher economies of scale, which translates into lower pay as-you-go prices.' The other options offer plausible-sounding accounting or tenancy explanations that AWS does not make.

8/10 · Billing, Pricing, and Support
A company is choosing between two architectures and finance wants the monthly AWS figure for each one before the choice is made. Which statement about AWS Pricing Calculator is accurate?
AIt reads the account's usage from last month and projects it forward.
BIt returns a quotation that AWS is contractually bound to honour.
CIt prices a configuration described to it, with no account usage needed.
DIt reports the taxes that apply in the country where the account sits.
Show answer & explanation
C is correct. Task Statement 4.2 covers the appropriate uses of AWS Pricing Calculator. Its user guide states that AWS Pricing Calculator 'is a free web-based planning tool that you can use to create cost estimates for using AWS services' and lists its use cases as 'Model your solutions before building them', 'Explore AWS service price points', 'Review the calculations behind your estimates', 'Plan your AWS spend' and 'Find cost saving opportunities'. On pricing it states that 'It provides an estimate of your AWS fees and charges, but the estimate doesn't include any taxes that might apply.' AWS Cost Explorer is the tool that works the other way round, from cost and usage an account has already incurred.

9/10 · Cloud Technology and Services · hard
A finance application runs on a Multi-AZ Amazon RDS DB instance deployment. New reporting pages have made the application slow, and a developer proposes sending those read-only queries to the copy of the database in the second Availability Zone. What should the team be told?
AThe standby carries no read traffic, and a read replica is what moves reads.
BThe standby answers reports once the application uses its endpoint.
CThe standby answers reads whenever the primary is busy, with no setting.
DThe standby can be promoted to carry the reports off the primary.
Show answer & explanation
A is correct. Task Statement 3.4 covers the relational database services. The Amazon RDS user guide states that 'A Multi-AZ DB instance deployment has one standby DB instance that provides failover support, but doesn't serve read traffic', and, on the read replica page, that 'Unlike a read replica, a standby replica can't serve read traffic'. The same read replica page states that 'A read replica is a read-only copy of a DB instance. You can reduce the load on your primary DB instance by routing queries from your applications to the read replica.' Only a Multi-AZ DB cluster deployment, which has two standby instances, can also serve reads.

10/10 · Cloud Technology and Services · hard
A manufacturer needs a control application to run at the plant, because the machines it steers react faster than a round trip to the nearest AWS Region allows. The company will not put its own staff in charge of the equipment that runs it, and it wants to go on working with the consoles and automation it already uses. Which AWS offering meets all of that?
AAn AWS Local Zone
BAn AWS Wavelength Zone
CAn AWS Direct Connect link
DAn AWS Outposts rack
Show answer & explanation
D is correct. Task Statement 3.1 asks candidates to identify deployment models including hybrid. The AWS Outposts user guide states that 'AWS Outposts is a fully managed service that extends AWS infrastructure, services, APIs, and tools to customer premises', that 'An Outpost is a pool of AWS compute and storage capacity deployed at a customer site' and that 'AWS operates, monitors, and manages this capacity as part of an AWS Region'. The Amazon EC2 'Regions and Zones' page separates the alternatives: 'A Local Zone is an extension of an AWS Region in geographic proximity to your users' and 'Wavelength Zones provide you with the ability to build applications that deliver ultra-low latencies to 5G devices and end users'.

CLF-C02 practice — FAQ
Is CLF-C02 worth it for non-technical roles?
Yes — AWS designed Cloud Practitioner for people who work with cloud teams without building on AWS every day: project and product managers, business analysts, sales and finance. The guide's target candidate has up to 6 months of exposure and may come from a non-IT background.
Should I take CLF-C02 before SAA-C03?
Take CLF-C02 first if you are new to cloud or want a confidence win; skip straight to SAA-C03 if you already have hands-on AWS experience. AWS does not require Cloud Practitioner before any Associate exam.
Does CLF-C02 include multiple-response questions?
Yes — the real exam mixes multiple-choice (one of four) with multiple-response items (two or more of five). ExamDeck's bank uses the single-answer format so every question has one defensible key and a rationale for each option.
How many questions is the CLF-C02 exam and how long is it?
65 questions (50 scored plus 15 unscored pilot items you cannot tell apart) in 90 minutes, delivered at a Pearson VUE test centre or online with a proctor.
What is the passing score for CLF-C02?
The passing score is 700 on a scaled score of 100–1,000 (roughly 70%). Aim for a consistent 80–85% on realistic practice exams before booking.
What is the CLF-C02 pass rate?
AWS does not publish official pass rates, so any exact percentage quoted online is unverified. The readiness signal that actually predicts passing: consistently holding 80–85% on realistic, full-length practice exams before you book.
What are the CLF-C02 eligibility requirements?
No prerequisites — anyone can register through AWS Training and Certification (Pearson VUE). AWS describes the target candidate as someone with up to 6 months of exposure to AWS Cloud design, implementation or operations; the exam is explicitly aimed at people from non-IT backgrounds as well.
How much does CLF-C02 cost?
The exam fee is $100 USD (regional pricing may differ — verify on aws.amazon.com). AWS offers a 50% discount voucher for the renewal exam once you are certified, and a free retake promotion appears periodically.
How long should I study for CLF-C02?
For most candidates, commonly reported 20–40 hours for candidates new to AWS (AWS publishes no official figure). What matters most is practising questions and analysing why each option is right or wrong — not just reading.
Does the CLF-C02 certification need recertification?
AWS certifications are valid for 3 years; renew by passing the latest version of this exam or a higher-level AWS exam (50% recertification voucher), or maintain for 1 year at a time through AWS Skill Builder.
Are ExamDeck's CLF-C02 questions exam dumps?
No — every question is original, written to test the concepts and reviewed before it ships, with an explanation linked to the source for every option. Dumps are stale, often wrong, and against AWS's policies.
