Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a backend pool in an Azure Load Balancer configuration.

Azure

backendAddressPools: [
  {
    name: 'myBackendPool',
    [1]: [
      { name: 'address1', ipAddress: '10.0.0.4' },
      { name: 'address2', ipAddress: '10.0.0.5' }
    ]
  }
]

💡 Hint

Common Mistakes

Using frontendIPConfigurations instead of backendAddresses

Confusing healthProbes with backendAddresses

The backendAddresses property lists the IP addresses of the backend pool members.

Complete the code to define a health probe that checks HTTP on port 80.

Azure

healthProbes: [
  {
    name: 'httpProbe',
    protocol: [1],
    port: 80,
    requestPath: '/health'
  }
]

Fix the error in the health probe configuration by selecting the correct property name for the probe interval.

Azure

healthProbes: [
  {
    name: 'tcpProbe',
    protocol: 'Tcp',
    port: 443,
    [1]: 15
  }
]

💡 Hint

Common Mistakes

Using probeIntervalInSeconds which is invalid

Using interval without units

The correct property name for the probe interval is intervalInSeconds.

4fill in blank

Fill both blanks to configure a backend pool and associate it with a health probe.

Azure

loadBalancingRules: [
  {
    name: 'rule1',
    frontendPort: 80,
    backendPort: 80,
    backendAddressPool: [1],
    probe: [2]
  }
]

💡 Hint

Common Mistakes

Using frontendPool instead of backend pool

Using tcpProbe when HTTP probe is expected

The load balancing rule connects the backend pool named myBackendPool with the health probe named httpProbe.

5fill in blank

hard

Fill all three blanks to define a health probe with HTTPS protocol, port 443, and a custom request path.

Azure

healthProbes: [
  {
    name: [1],
    protocol: [2],
    port: [3],
    requestPath: '/customhealth'
  }
]

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

A'httpsProbe'

B'Https'

C443

D'Http'

💡 Hint

Common Mistakes

Using 'Http' protocol for HTTPS port

Using numeric port as string

The health probe is named httpsProbe, uses the Https protocol on port 443 with a custom path.
