Google ACE Setting Up a Cloud Solution Environment Practice Question

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  curl https://sdk.cloud.google.com | bash

  Why it's wrong here

  The curl command pipes a remote bootstrap script directly into bash, which runs an interactive installer that typically places the SDK in your home directory and modifies your shell profile. This method is intended for single-user setups and does not leverage the operating system's package manager, so future updates are not managed through apt. It also requires continuous user input, making it unsuitable for automated or system-wide installation scenarios.

• ✗

  gcloud init

  Why it's wrong here

  gcloud init is a configuration command that runs only after the Cloud SDK is already present on the machine. It guides you through authentication, selecting a project, and setting default compute region/zone, but it performs no file installation or package management. Executing it before installing the SDK would just produce a "command not found" error, so it cannot be used to install the SDK itself.

• ✗

  sudo apt-get install google-cloud-sdk

  Why it's wrong here

  Running sudo apt-get install google-cloud-sdk without any prior repository configuration will fail because Debian/Ubuntu's default package lists do not contain the Cloud SDK. The official Google Cloud packages are distributed from packages.cloud.google.com, so you must first add that apt repository and import its GPG key; only then will apt recognize the package name and install it. Omitting this setup step is the most common mistake when attempting the package-manager installation route.

• ✓

  echo 'deb [signed-by=/usr/share/keyrings/cloud.google.gpg] https://packages.cloud.google.com/apt cloud-sdk main' | sudo tee -a /etc/apt/sources.list.d/google-cloud-sdk.list

  Why this is correct

  This command correctly configures the official Cloud SDK apt repository on a Debian or Ubuntu system by appending a sources.list entry with the signed-by parameter pointing to the imported Google signing key at /usr/share/keyrings/cloud.google.gpg. Using signed-by binds the repository to that specific key instead of trusting the global apt keyring, which is the recommended security practice. After running this, you still need to run sudo apt-get update and sudo apt-get install google-cloud-sdk, but this repository definition is the essential correct foundation for the package-manager installation method.
