Q

Is it recommended to run a database within an AWS Elastic Beanstalk environment?

Q

What configuration file is required for deploying to AWS Elastic Beanstalk Single Container platform?

A

One of the following:
- Dockerfile: to build a Docker image and runs the container
- Dockerrun.aws.json (v1): to use existing image and configure ports, volumes, and environment variables
- docker-compose.yml: if Docker Compose is required for deployment

19
Q

What configuration file is required for deploying to AWS Elastic Beanstalk Multi-Container platform?

A

Dockerrun.aws.json (v2): to defines multiple container configurations, including images, ports, volumes, environment variables, and ECS task definitions

20
Q

What AWS Elastic Beanstalk feature controls how application versions are deployed to an environment?

A

Deployment Strategies (Policies)

21
Q

What deployment strategies does AWS Elastic Beanstalk provide?

A
  • All-at-once
  • Rolling
  • Rolling with additional batch
  • Immutable
  • Traffic Splitting
22
Q

Which AWS Elastic Beanstalk deployment strategy performs an in-place deployment on all instances, causing a brief outage and is commonly used for development and test environments?

A

All-at-once

23
Q

Which AWS Elastic Beanstalk deployment strategy divides instances into batches and deploys to one batch at a time, causing a temporary loss in capacity but no additional cost?

A

Rolling (batch size can be configured)

24
Which AWS Elastic Beanstalk deployment strategy deploys updates in batches but creates new EC2 instances for the first batch instead of using existing ones, preventing capacity loss at the cost of increased resource usage?
Rolling with additional batch
25
Which AWS Elastic Beanstalk deployment strategy provisions new instances for deployment instead of updating existing ones, providing the safest rollback option?
Immutable
26
Which AWS Elastic Beanstalk deployment strategy enables immutable deployment while gradually shifting traffic to new instances, providing flexibility for testing, and incurring increased costs?
Traffic splitting
27
What are the two types of AWS RDS integration supported by AWS Elastic Beanstalk?
- RDS within EB Environment: Linked to a single Environment - RDS outside of EB Environment: Can be used by multiple Environments
28
What considerations should be taken into account when using AWS RDS linked to AWS Elastic Beanstalk Environment?
- If the environment is deleted, RDS is deleted too - Different environments have different databases and data - Environment properties (RDS_*) are automatically created and provided to all applications within the environment - Typically used for small-scale development and test environments
29
What considerations should be taken into account when using AWS RDS outside of AWS Elastic Beanstalk?
- Multiple EB Environments can use the same RDS instance - The data layer is outside the Environment, so if the environment is deleted, data remains untouched - Environment properties (RDS_*) must be created manually
30
What directory in the application source code contains configuration files for customizing the AWS Elastic Beanstalk environment and its resources?
The `.ebextensions/` directory contains `*.config` files in YAML or JSON format for environment configuration
31
What section of an `.ebextensions/*.config` file in AWS Elastic Beanstalk is used to define configuration option values?
`option_settings`
31
What section of an `.ebextensions/*.config` file in AWS Elastic Beanstalk is used to define additional AWS resources beyond the functionality provided by configuration options?
`Resources`
31
What sections of an `.ebextensions/*.config` file in AWS Elastic Beanstalk allow configuring the EC2 instances launched in the environment?
- `packages` - `sources` - `files` - `users` - `groups` - `commands` - `container_commands` - `services`
32
What configuration file can be placed in the root directory of the source bundle to define settings such as `EnvironmentName`, `EnvironmentLinks`, `EnvironmentTier`, `Platform`, `SolutionStack`, `OptionSettings`, `Tags`, and `CName` when creating an AWS Elastic Beanstalk environment?
`env.yaml`
33
What actions are required to enable HTTPS for an AWS Elastic Beanstalk environment?
An SSL certificate must be applied to the ELB via the EB Console or configured using `.ebextensions`, additionally, security group rules must allow inbound traffic on port 443
34
Which AWS Elastic Beanstalk feature allows creating a new environment by duplicating an existing one, including its configuration and associated AWS resources?
Cloning
35
What considerations should be taken into account when using the AWS Elastic Beanstalk clone feature?
- Option settings, environment variables, and other settings are copied - Data from RDS to clone is not copied - Any unmanaged changes to resources are not included - Security groups for ingress are considered unmanaged changes *Changes to AWS resources that applied using tools other than the Elastic Beanstalk console, command-line tools, or API are considered unmanaged changes
36
What CLI command is used to utilize the AWS Elastic Beanstalk clone feature?
`$ eb clone `
37
What are the primary use cases for the AWS Elastic Beanstalk clone feature?
- Create a new environment by cloning an existing one - Copy an environment for Q/A testing or other use cases
38
Can you use the AWS Elastic Beanstalk clone feature to clone an environment to a different platform branch?
No, the environment can only be cloned to a different platform version of the same platform branch
39
When creating a custom platform in AWS Elastic Beanstalk using a Packer template, which parameters must be specified in the `custom_platform.json` file?
- `source_ami` - `region`
40
What happens to instances managed by AWS Elastic Beanstalk that are terminated due to failed deployments?
Elastic Beanstalk automatically replaces the failed instances with new instances running the application version from the most recent successful deployment
41
Which file must be included in the source bundle when deploying a worker application for periodic background tasks in Elastic Beanstalk?
`cron.yaml`
42
How can you migrate an Elastic Beanstalk environment between AWS accounts?
By using saved configurations, which are YAML formatted templates that define an environment's platform version, tier, and configuration settings, and can be applied to new or running environments
