• Question 11:

  You migrated a live On-Premise application to Magento Commerce Cloud Pro. The performance on Staging and Production is fine. However, the internal testing team notices overall performance degradation on the Integration environment.

  Why is this happening?

  A. The Integration branch uses Platform-as-a-Service shared resources

  B. Xdebug is always enabled on the Integration branch

  C. The Staging and Production environments are consuming all available resources

  D. The Integration branch services have not been optimized in the .magento/services.yaml file

  Correct Answer: D

• Question 12:

  You added a grunt autoprefixer command, which adds CSS vendor prefixes like -webkit- and -moz- to CSS files generated by the setup:static-content:deploy command.

  After deployment you still see CSS files without prefixes. The hooks section in the .magento.app.yaml file is:

  hooks: build: | npm install grunt autoprefixer php ./vendor/bin/ece-tools build:generate php ./vendor/bin/ece-tools build:transfer deploy: | php ./vendor/bin/ece-tools deploy

  Considering static assets are being generated on the build phase, why are CSS prefixes missing?

  A. Custom commands can be run only on the deploy phase

  B. CSS vendor prefixes must be added to CSS files locally and committed as part of a theme

  C. The static assets were not generated yet when the grunt command ran

  D. The custom command was run before static assets were transferred into the init directory

  Correct Answer: B

• Question 13:

  You are tasked to improve the user experience of the most visited product pages after deploying releases to Production. The aim is to reduce initial page load times.

  How do you achieve this?

  A. Create a custom build command and use CURL to cache the page

  B. Use the Magento Admin to configure Fastly to cache the pages after deployment

  C. Modify the post_deploy hook in the .magento.app.yaml file to include the URLs as arguments to the ece-tools command

  D. Use the WARM_UP_PAGES variable in the .magento.env.yaml file to cache the pages during post_deploy

• Question 14:

  You added the env:ADMIN_PASSWORD variable in the Project Web UI to change a Magento admin user's password. After deployment you are unable to login using the new password.

  What causes this?

  A. When you add a variable, the build stage is being skipped, because the codebase has not been changed. You must push a commit to trigger a full deploy

  B. Deploy scripts read configuration from the environment variable called $MAGENTO_CLOUD_VARIABLES, which contains an array of variables which were set without the env: prefix

  C. Variables which are set using the Project Web UI are not available on the build phase, the admin password variable should be set in the .magento.env.yaml file

  D. The sensitive option is required for env:ADMIN_PASSWORD variable

  Correct Answer: C

• Question 16:

  A custom module that adds a new console command for bin/magento has just been built. Deploying this to the Production environment on your Pro plan site causes the build phase to fail.

  You find this occurs when you inject certain Magento core classes in your console command class. The command works on your local environment.

  Why does this occur?

  A. The injected class logged to the exception log file, but a different logging implementation is used during deployment.

  B. Files were written to the root Magento directory, which is read-only on Magento Commerce Cloud.

  C. A connection to the database was attempted, which is not available during the build phase.

  D. The three webservers generated different content, which causes the build to be rolled back for safety.

  Correct Answer: A
