Which Amazon EC2 feature allows you to run a script automatically when an EC2 instance first starts to install software and configure the environment?

A EC2 Image Builder
B EC2 user data check_circle
C EC2 instance metadata
D EC2 placement groups
lightbulb

Explanation

EC2 user data is a script that runs automatically on first boot commonly used to install software configure settings and pull application code. Image Builder automates AMI creation. Instance metadata provides information about the running instance. Placement groups control instance placement.

A company plans to use an Amazon Snowball Edge device to transfer files to the AWS Cloud. Which activities related to a Snowball Edge device are available to the company at no cost?

A Use of the Snowball Edge appliance for a 10-day period
B The transfer of data out of Amazon S3 and to the Snowball Edge appliance
C The transfer of data from the Snowball Edge appliance into Amazon S3 check_circle
D Daily use of the Snowball Edge appliance after 10 days
lightbulb

Explanation

Importing data INTO S3 is always free. AWS charges for appliance rental and data egress (data leaving AWS). A & D are wrong because appliance use is always charged. B is wrong because moving data OUT of S3 is egress and costs money.

Which Amazon EC2 feature provides information about the running instance such as instance ID AMI ID and IAM role accessible from within the instance?

A EC2 user data
B AWS Systems Manager
C EC2 instance metadata service check_circle
D AWS Config
lightbulb

Explanation

The EC2 Instance Metadata Service provides instance-specific information accessible from within the instance at the link-local address 169.254.169.254. This includes instance ID public IP IAM role credentials and more. User data runs scripts at launch. Systems Manager manages instances remotely.

A company needs to run a graphics-intensive application for video rendering on AWS. Which EC2 instance family should the company use?

A General purpose M family
B Memory optimized R family
C Accelerated computing G family check_circle
D Storage optimized I family
lightbulb

Explanation

Accelerated computing instances including the G family provide GPU acceleration for graphics-intensive workloads like video rendering 3D visualization and game streaming. General purpose M balances resources. Memory optimized R is for RAM-intensive workloads. Storage optimized I is for high I/O.

A company has a centralized group of users with large file storage requirements that have exceeded the space available on premises. The company wants to extend its file storage capabilities while retaining local performance. What is the MOST operationally efficient AWS solution?

A Create an Amazon S3 bucket for each user. Mount each bucket by using an S3 file system mounting utility.
B Configure and deploy an AWS Storage Gateway file gateway. Connect each user's workstation to the file gateway. check_circle
C Move each user's working environment to Amazon WorkSpaces. Set up an Amazon WorkDocs account for each user.
D Deploy an Amazon EC2 instance and attach an Amazon EBS Provisioned IOPS volume. Share the EBS volume directly with the users.
lightbulb

Explanation

Storage Gateway File Gateway caches hot data locally (preserving performance) while storing everything in S3. A adds per-user complexity. C migrates entire desktops which is overkill. D requires manual management of EC2 and EBS.

Which Amazon S3 storage class is designed for data that is accessed less than once a month and requires millisecond access?

A S3 Standard
B S3 Standard-IA
C S3 One Zone-IA
D S3 Glacier Instant Retrieval check_circle
lightbulb

Explanation

S3 Glacier Instant Retrieval is designed for rarely accessed data that still requires millisecond retrieval. It costs less than Standard-IA and is ideal for quarterly access patterns. Standard is for frequently accessed data. Standard-IA is for data accessed once a month or less. One Zone-IA stores data in a single AZ.

7
Domain 3 - Cloud Technology and Services

Which Amazon S3 storage class stores data in only one Availability Zone at a lower cost but with less durability than multi-AZ storage classes?

A S3 Standard-IA
B S3 One Zone-IA check_circle
C S3 Glacier Flexible Retrieval
D S3 Intelligent-Tiering
lightbulb

Explanation

S3 One Zone-IA stores data in a single AZ at 20% less cost than Standard-IA but with less durability since data is lost if the AZ is destroyed. It is suitable for infrequently accessed data that can be recreated. Standard-IA stores across multiple AZs. Glacier is for archival. Intelligent-Tiering auto-tiers.

8
Domain 3 - Cloud Technology and Services

Which Amazon RDS feature provides automatic failover to a standby replica in a different Availability Zone with minimal downtime?

A Read replicas
B Multi-AZ deployment check_circle
C Automated backups
D RDS Proxy
lightbulb

Explanation

RDS Multi-AZ maintains a synchronous standby replica in a different AZ. If the primary fails RDS automatically fails over to the standby with minimal downtime typically 1 to 2 minutes. Read replicas are for scaling reads not HA failover. Automated backups provide point-in-time recovery. RDS Proxy manages connections.

9
Domain 3 - Cloud Technology and Services

Which Amazon RDS feature allows you to offload read traffic from the primary database to improve performance?

A Multi-AZ deployment
B RDS Proxy
C Read replicas check_circle
D Automated backups
lightbulb

Explanation

Read replicas are asynchronous copies of the primary database that serve read traffic reducing load on the primary. They can also be promoted to standalone databases for DR. Multi-AZ is for HA failover. RDS Proxy manages connections. Automated backups provide point-in-time recovery.

Domain 3 - Cloud Technology and Services

A company is running and managing its own Docker environment on Amazon EC2 instances. The company wants an alternative to help manage cluster size, scheduling, and environment maintenance. Which AWS service meets these requirements?

A AWS Lambda
B Amazon RDS
C AWS Fargate check_circle
D Amazon Athena
lightbulb

Explanation

Fargate is serverless container compute — it handles cluster sizing, scheduling, and infrastructure automatically. Lambda is for event-driven functions. RDS is a managed database. Athena is a SQL query service for S3.
