You want to secure a Kafka cluster so that only authenticated users can produce or consume messages, and all traffic is encrypted. Which combination of settings achieves this best?

hard📝 Application Q15 of 15

Kafka - Security

AUse PLAINTEXT protocol with ACLs to restrict access, no encryption needed

Enable SSL encryption with <code>security.protocol=SASL_SSL</code>, configure SASL authentication, and set ACLs for user permissions

CEnable SASL_PLAINTEXT for authentication and rely on network firewall for encryption

DUse SSL only without SASL or ACLs to simplify configuration

Step-by-Step Solution

Solution:

Step 1: Ensure encryption and authentication
Using security.protocol=SASL_SSL enables both encryption (SSL) and authentication (SASL).
Step 2: Control access with ACLs
ACLs restrict which authenticated users can produce or consume messages, enforcing permissions.
Final Answer:
Enable SSL encryption with security.protocol=SASL_SSL, configure SASL authentication, and set ACLs for user permissions -> Option B
Quick Check:
Encryption + Authentication + ACLs = Secure Kafka [OK]

Quick Trick: Combine SASL_SSL, SASL auth, and ACLs for full security [OK]

Common Mistakes:

Using PLAINTEXT disables encryption
Relying on firewall instead of encryption
Skipping ACLs allows unauthorized access
