After running these commands:
hdfs key create myKey
hdfs dfsadmin -createEncryptionZone -keyName myKey -path /secureZone
what is the expected outcome?

AThe command fails because /secureZone already exists

BThe key myKey is deleted and /secureZone remains unencrypted

CAn encryption zone named /secureZone is created using the key myKey

DFiles in /secureZone are automatically decrypted

Step-by-Step Solution

Solution:

Step 1: Create encryption key
The command hdfs key create myKey creates a new encryption key named 'myKey'.
Step 2: Create encryption zone
The command hdfs dfsadmin -createEncryptionZone -keyName myKey -path /secureZone creates an encryption zone at /secureZone using 'myKey'.
Final Answer:
An encryption zone named /secureZone is created using the key myKey -> Option C
Quick Check:
Commands create key and encryption zone successfully [OK]

Quick Trick: Create key first, then encryption zone with that key [OK]
