Question 608 of 964
PCD Building and testing applications Practice Question
Which TWO statements about building container images for Google Cloud Run are correct? (Choose TWO.)
⚠ Common exam trap
The PCD exam often tests the misconception that Cloud Run mandates port 8080 or requires HTTP/1.1, but the actual requirement is that the container must respond to health checks on the same port as the main application and must be stateless.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The container must respond to health checks on the same port as the main application.
Cloud Run requires the container to respond to health checks (e.g., HTTP GET /health) on the same port as the main application. Cloud Run uses the same port for both user requests and health check probes; if the health check fails, the container is restarted. This ensures the container is always ready to serve traffic.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The container must use HTTP/1.1; HTTP/2 is not supported.
Why it's wrong here
Cloud Run supports HTTP/2 (gRPC).
- ✓
The container must respond to health checks on the same port as the main application.
Why this is correct
Health checks are sent to the container's port; the app must respond with 200 OK.
- ✓
The container must be stateless and not rely on local file system persistence.
Why this is correct
Cloud Run is stateless; any local file system writes are ephemeral.
- ✗
The container must listen on port 8080 by default.
Why it's wrong here
The container must listen on the port defined by the PORT environment variable, which is 8080 by default but can be changed.
- ✗
The container must run as root user.
Why it's wrong here
Cloud Run recommends running as non-root for security.
