Health checks configuration in GCP - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to specify the protocol used in the health check.

GCP

{
  "name": "basic-health-check",
  "type": "HTTP",
  "httpHealthCheck": {
    "port": 80,
    "requestPath": "/health",
    "protocol": "[1]"
  }
}

💡 Hint

Common Mistakes

Choosing TCP or SSL when the health check is HTTP-based.

Using HTTPS when the port is 80.

The protocol for this health check is HTTP, so the correct value is "HTTP".

medium

Complete the code to set the check interval in seconds.

GCP

{
  "name": "custom-health-check",
  "checkIntervalSec": [1],
  "timeoutSec": 5
}

💡 Hint

Common Mistakes

Setting the interval too low like 2 seconds, causing unnecessary load.

Setting the interval too high like 60 seconds, causing slow detection.

The check interval is commonly set to 10 seconds for a balance between responsiveness and load.

Fix the error in the health check configuration by selecting the correct port number.

GCP

{
  "name": "tcp-health-check",
  "tcpHealthCheck": {
    "port": [1]
  }
}

Drag options to blanks, or click blank then click option'

C8080

D22

Attempts:

💡 Hint

Common Mistakes

Using port 80 or 443 which are for HTTP/HTTPS, not TCP health checks.

Using port 22 which is for SSH, unrelated to health checks.

The TCP health check should target port 8080 where the service listens, not standard HTTP or SSH ports.

4fill in blank

hard

Fill both blanks to configure a health check with a 5-second timeout and 3 healthy threshold.

GCP

{
  "name": "advanced-health-check",
  "timeoutSec": [1],
  "healthyThreshold": [2]
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Confusing timeout with interval values.

Setting healthy threshold too low or too high.

The timeout is set to 5 seconds and the healthy threshold to 3 successful checks before marking healthy.

5fill in blank

hard

Fill all three blanks to create a health check that uses HTTPS, checks path '/status', and has an unhealthy threshold of 5.

GCP

{
  "name": "secure-health-check",
  "httpsHealthCheck": {
    "port": 443,
    "requestPath": "[1]",
    "protocol": "[2]"
  },
  "unhealthyThreshold": [3]
}

Drag options to blanks, or click blank then click option'

A/status

BHTTPS

C5

D/health

Attempts:

3 left

💡 Hint

Common Mistakes

Using HTTP protocol with port 443.

Using wrong request path like '/health' instead of '/status'.

Setting unhealthy threshold too low.

The health check uses HTTPS protocol, checks the '/status' path, and marks unhealthy after 5 failed checks.
