AWS Certified Solutions Architect Associate (SAA-C02) Exam Prep Course - Choosing Resilient Storage

The video tutorial provides an in-depth look at AWS's global infrastructure, focusing on the resiliency and storage options available. It covers the division of regions and availability zones, and how these contribute to data resiliency. The tutorial explores various AWS storage services like S3, EBS, EFS, and FSX, highlighting their features and configurations. A detailed examination of S3 storage classes and object management is provided, including bucket creation, versioning, and permissions. The video emphasizes the flexibility and options available for managing data storage in AWS.

What is the primary purpose of AWS's global infrastructure?

• To ensure data resiliency and availability

• To reduce network latency

• To offer high-speed data processing

• To provide low-cost storage solutions

Which AWS service is typically used for storing boot volumes of EC2 instances?

• Amazon S3

• Amazon EFS

• Amazon FSx

• Amazon EBS

Which AWS service is used for network file storage for Linux systems?

• Amazon S3

• Amazon FSx

• Amazon EFS

• Amazon EBS

What is a key feature of Amazon S3 that makes it flexible for various purposes?

• Its ability to store data in a single availability zone

• Its global resource nature and unique bucket naming

• Its integration with Amazon EC2

• Its support for Windows file systems

What must be ensured when creating a new S3 bucket?

• The bucket is set to public access

• The bucket is encrypted by default

• The bucket is created in multiple regions

• The bucket name is globally unique

What is a benefit of using versioning in S3?

• It increases data retrieval speed

• It allows public access to data

• It reduces storage costs

• It prevents accidental data deletion

Which S3 storage class is best suited for data that is rarely accessed but needs to be retrieved quickly when required?

• Intelligent-Tiering

• Standard-IA

• Standard

• Glacier

What is the main advantage of using Intelligent-Tiering storage class in S3?

• It stores data in a single availability zone

• It provides the highest performance for frequently accessed data

• It automatically adjusts storage tiers based on usage patterns

• It offers the lowest cost for data storage

What is a common misconception about folders in S3?

• They represent a file system structure

• They are necessary for data replication

• They can store metadata about objects

• They are used to organize data hierarchically

Why might a user be denied read access to an S3 object URL?

• The object is stored in Glacier

• The user has not authenticated properly

• The object is in a private bucket

• The object is encrypted
