Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
10 GB
Why it's wrong here
The persistent home directory in Cloud Shell is fixed at 5 GB; 10 GB is not a documented quota. Some users confuse this with the total free storage offered across other Google services, but within Cloud Shell, the $HOME directory is specifically limited to 5 GB of persistent block storage.
- ✗
1 GB
Why it's wrong here
1 GB is the memory capacity of the temporary Cloud Shell virtual machine, not the storage capacity. The VM that hosts Cloud Shell has 1 vCPU and 1 GB RAM, but the durable home directory that persists across sessions is a separate 5 GB persistent disk, so 1 GB is incorrect for this question.
- ✗
20 GB
Why it's wrong here
20 GB is likely a misread from the ephemeral boot disk of the temporary Cloud Shell VM, which can be larger and is rebuilt each session. However, only the persistent $HOME directory, sized at 5 GB, stores user data across sessions; any data outside that directory is lost when the session ends.
- ✓
5 GB
Why this is correct
Correct. Cloud Shell provisions a 5 GB persistent home directory, mounted at $HOME, that survives between sessions. This is the documented, fixed quota for free Cloud Shell usage, regardless of session time or usage patterns.
