AIt stores Hadoop data securely
BIt issues tickets to users and services after verifying credentials
CIt manages Hadoop cluster resources
DIt encrypts data stored in HDFS
Step-by-Step Solution
Solution:

  1. Step 1: Understand the role of KDC in Kerberos

    The KDC is responsible for authenticating users and services by issuing tickets after verifying their credentials.

  2. Step 2: Differentiate KDC from other Hadoop components

    Other options describe storage, resource management, or encryption, which are not KDC's functions.

  3. Final Answer:

    It issues tickets to users and services after verifying credentials -> Option B

  4. Quick Check:

    Kerberos KDC function = Ticket issuing [OK]
Quick Trick: KDC issues tickets after verifying identity [OK]
