B Correct answer
Explanation

TV inputs from antenna or cable use Radio Frequency (RF) signals - typically VHF (very high frequency) or UHF (ultra high frequency). RF is the standard term for radio-frequency signals used to broadcast television. IF (Intermediate Frequency) is used internally within the TV after tuning, AF (Audio Frequency) is sound-only, and SAP is a secondary audio program channel.

  3. Partition by Round-Robin

  4. Partition by Key
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Broadcast, Partition by Round-Robin, and Partition by Key are all data partitioning methods in Ab Initio that distribute data across multiple partitions. Replicate, however, is NOT a partitioning method - it copies the entire dataset to every partition (full replication). The key difference is that partitioning divides data (each record goes to one partition), while replication duplicates it (every record goes to all partitions).
