Microservices - Configuration and Secrets Management

Which of the following pseudocode snippets correctly verifies if the feature toggle betaFeature is active?

Aif (featureToggle['betaFeature'] == true) { activateBeta(); }

Bif (featureToggle.isEnabled = 'betaFeature') { activateBeta(); }

Cif (featureToggle.isEnabled('betaFeature')) { activateBeta(); }

Dif (featureToggle.isEnabled('betaFeature') == false) { activateBeta(); }

Step-by-Step Solution

Solution:

Step 1: Understand method usage
The method isEnabled should be called with the feature name as a string argument.
Step 2: Analyze options
if (featureToggle.isEnabled('betaFeature')) { activateBeta(); } correctly calls isEnabled('betaFeature') and activates the feature if true.
Step 3: Identify incorrect options
if (featureToggle.isEnabled = 'betaFeature') { activateBeta(); } uses assignment instead of comparison; C uses incorrect syntax; D activates feature when toggle is false.
Final Answer:
if (featureToggle.isEnabled('betaFeature')) { activateBeta(); } -> Option C
Quick Check:
Method call with string argument is correct [OK]

Quick Trick: Use method call with string feature name [OK]
