The AWS Well-Architected Tool provides a plan on how to architect for the cloud using established best practices.
The AWS Well-Architected Tool helps cloud architects review and improve their workloads based on AWS best practices across the six pillars of the Well-Architected Framework.
___________focuses on achieving the lowest price for a system/workload. Optimize the cost while considering the account needs without ignoring factors like security, reliability, and performance.
Cost Optimization is the Well-Architected pillar focused on achieving the lowest cost while maintaining appropriate security, reliability, and performance for a workload.
A pillar focuses on ensuring a system/workload delivers maximum performance for a set of AWS resources utilized.
Performance Efficiency ensures IT and computing resources efficiently meet system requirements. It covers selecting the right resource types and sizes and monitoring performance.

Amazon EC2 ________ allow you to request spare Amazon EC2 computing capacity for up to 90 percent off the On-Demand price.
Amazon EC2 Spot Instances let you use spare AWS compute capacity at up to 90% discount compared to On-Demand prices, ideal for fault-tolerant batch and stateless workloads.
Which of the pricing options do customers pay per hour for compute?
On-Demand pricing charges by the hour (or per second for some instance types) with no upfront commitment, providing maximum flexibility for variable or unpredictable workloads.
Cost varies between regions(True/False)
The correct answer is: True.
In AWS, you need to buy servers to host application.(True/False)
FALSE — In AWS, you do not need to buy physical servers. AWS provides virtual compute resources on demand, eliminating upfront hardware purchases.
Cloud computing converts capital expenditure into operational expenditure by:
Cloud computing converts upfront capital expenditure (CapEx) — buying servers — into operational expenditure (OpEx) by paying only for the resources consumed.
Which of the following is NOT one of the six advantages mentioned for cloud computing?
The six advantages of cloud computing include: Trade CapEx for OpEx, benefit from massive economies of scale, stop guessing capacity, increase speed and agility, stop spending on data centers, and go global in minutes.
On-premise data centers compared to cloud generally have:
On-premises data centers require high upfront capital investment in hardware and facilities, in contrast to cloud's pay-as-you-go model.
Which service model provides virtual servers, storage and networking while you manage the OS?
The correct answer is: IaaS.
Which cloud deployment model mixes on-premises and cloud resources?
On-premises data centers require high upfront capital investment in hardware and facilities, in contrast to cloud's pay-as-you-go model.
AWS launched its cloud services in which year?
The correct answer is: 2006.
A benefit described as "stop spending money on undifferentiated heavy lifting" means:
AWS handles undifferentiated heavy lifting — the common, time-consuming infrastructure tasks — so teams can focus on business logic that differentiates their applications.
Which of the following is a Public Cloud example?
In the Public cloud model, applications are fully hosted on cloud provider infrastructure and accessible over the internet. AWS is a public cloud provider.
Which statement is true about global reach in cloud?
The correct answer is: You can deploy across regions in minutes.
Which is an example of PaaS on AWS?
PaaS provides a platform to develop, run, and manage applications without managing the underlying infrastructure. Examples include AWS Elastic Beanstalk and Google App Engine.
Which is a typical use-case of SaaS?
SaaS delivers fully managed software applications over the internet. Gmail and Salesforce are SaaS examples; AWS doesn't typically offer SaaS directly but enables customers to build them.
A Community Cloud is best described as:
A Community Cloud is shared among organizations with common concerns (e.g., regulatory requirements) and is managed by the organizations or a third party.
One advantage of cloud is "stop guessing capacity" — this refers to:
Cloud's elastic scaling eliminates the need to guess infrastructure capacity. You can scale up or down dynamically to match actual demand.
Which characteristic is NOT typically true for cloud providers achieving economies of scale?
Cloud providers achieve massive economies of scale by aggregating usage from hundreds of thousands of customers, translating to lower pay-as-you-go prices.
Which is TRUE about pay-as-you-go pricing?
Pay-as-you-go pricing means you pay only for the compute, storage, and other resources you actually consume, with no upfront commitments or long-term contracts.
Which cloud model gives you the most control over the OS?
The correct answer is: IaaS.
Which deployment model would you choose to meet strict regulatory or data locality needs?
The correct answer is: Private Cloud.
Which is NOT a responsibility of the cloud provider in a typical IaaS offering?
IaaS (Infrastructure as a Service) provides virtualized computing, storage, and networking. You manage the OS and above while the provider handles the physical infrastructure.
Which statement best matches "Go Global in Minutes"?
Cloud providers have regions worldwide, allowing you to replicate and deploy applications globally in minutes rather than the months it would take to procure and set up physical infrastructure.
Which of the following is a common reason organizations adopt cloud?
AWS Organizations use Organizational Units (OUs) to hierarchically group AWS accounts. Service Control Policies (SCPs) can be applied to OUs for governance.
Which is an example of stopping undifferentiated heavy lifting?
AWS handles undifferentiated heavy lifting — the common, time-consuming infrastructure tasks — so teams can focus on business logic that differentiates their applications.
Which aspect is typically better in cloud than in a traditional data center?
The correct answer is: Elastic scalability.
Which of the following pairs the correct service model with an example?
The correct answer is: PaaS — Amazon Elastic Beanstalk.
Why might an organization choose a hybrid cloud?
AWS Organizations use Organizational Units (OUs) to hierarchically group AWS accounts. Service Control Policies (SCPs) can be applied to OUs for governance.

The correct answer is: True.
One of the benefit of the cloud is agility, resource can be provisioned with few click.True/False
The correct answer is: True.
In which of the following models is an application hosted completely on the cloud?
In the Public cloud model, all resources and applications are hosted on cloud provider infrastructure (e.g., AWS) and delivered over the internet. Private and Hybrid models retain some on-premises components.
AWS is responsible for protecting the Global infrastructure based on shared responsibility model .
The AWS Shared Responsibility Model: AWS manages security 'of' the cloud (infrastructure, physical security), while customers manage security 'in' the cloud (data, OS, applications).
Which of the following are best practices of IAM?
IAM best practices include enabling MFA on the root account and deleting root account access keys. You cannot delete the root user account itself; instead, lock it down. Deleting the root password is also not a standard practice.
Which of the below options is NOT a security best practice?
Using the root account for daily activities is a security anti-pattern. Best practice is to lock away root credentials, use IAM users/roles with least privilege, and enable MFA.
To organize and manage AWS resources, _________ is used.
AWS Resource Groups enable you to organize AWS resources by tags or CloudFormation stacks, making it easier to manage, automate, and track costs for related resources.
AWS is responsible for protecting the Global infrastructure based on shared responsibility model .

Security in the cloud means customers are responsible for securing everything they deploy in the cloud
The correct answer is: True.
To simplify the assignment of similar permissions for many users, ______ is used.
