Every day the CloudNinja home page asks one AWS question at Cloud Practitioner level. These are the 7 questions before October 16, 2026, each with every option, the correct answer and why it is right.
C.A central store for structured and unstructured data✓ Correct answer
D.A backup copy of an EC2 instance
Why C is right
A data lake is a central repository, often built on Amazon S3, that stores structured and unstructured data, both raw and transformed, at any scale for analytics and ML. A single relational table is far more rigid and holds only structured records.
Which AWS Cloud Adoption Framework (AWS CAF) perspective focuses on culture, organizational structure, leadership, and workforce?
A.Business
B.Governance
C.People✓ Correct answer
D.Operations
Why C is right
The People perspective bridges technology and business, helping organizations evolve a culture of continuous learning, with a focus on culture, organizational structure, leadership, and workforce. The Business perspective focuses on making cloud investments accelerate business outcomes.
Which AWS service lets partners or finance teams create custom pro forma bills for showback and chargeback?
A.AWS Cost Explorer
B.AWS Budgets
C.AWS Billing Conductor✓ Correct answer
D.AWS Marketplace
Why C is right
AWS Billing Conductor creates a second, pro forma version of your costs using your own pricing plans, rules and custom line items, so you can charge back teams or customers. Cost Explorer only shows your actual AWS-determined costs and cannot reprice them.
An Amazon S3 bucket policy is an example of which type of IAM policy?
A.An identity-based policy
B.A service control policy
C.A password policy
D.A resource-based policy✓ Correct answer
Why D is right
A resource-based policy is attached directly to a resource, such as an S3 bucket, and says who can access it and what they can do. Identity-based policies are attached to IAM users, groups or roles instead.
Which AWS service gives your application two static anycast IP addresses that act as a fixed global entry point?
A.Amazon Route 53
B.An Elastic IP address
C.AWS Global Accelerator✓ Correct answer
D.Amazon CloudFront
Why C is right
AWS Global Accelerator provides two static IPv4 addresses, anycast from the AWS edge network, and routes traffic over the AWS global network to healthy endpoints. An Elastic IP address is a single static IPv4 address in one Region, not an anycast global entry point.
Which Amazon RDS feature automatically adds storage to a DB instance when it is running low on free space?
A.Read replicas
B.Multi-AZ deployment
C.Storage autoscaling✓ Correct answer
D.Amazon RDS Proxy
Why C is right
With storage autoscaling turned on, Amazon RDS detects when free space is running low and increases the allocated storage automatically, so you avoid scaling it by hand. Read replicas add read capacity but do not add storage to the primary instance.
Linux applications access Amazon EFS file systems using which protocol?
A.SMB
B.iSCSI
C.NFS✓ Correct answer
D.SFTP
Why C is right
Amazon EFS supports the Network File System (NFS) protocol, versions 4.0 and 4.1, so Linux tools and apps can mount it like any network share. SMB is the Windows file sharing protocol used by Amazon FSx for Windows File Server.
