Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implementing Conflict Detection and Resolution (CDR) rules for active-active multi-master topologies
GoldenGate architectures require conflict resolution, careful handling of DDL changes, and proper handling of sequences.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Routing all write transactions through a single read-only replica without replication
Why it's wrong here
Incorrect. Read-only replicas cannot accept write transactions.
- ✓
Implementing Conflict Detection and Resolution (CDR) rules for active-active multi-master topologies
Why this is correct
Correct. CDR prevents data corruption during simultaneous writes in active-active setups.
- ✓
Configuring unique primary key generation strategies (e.g., sequence offsets) to prevent key collisions
Why this is correct
Correct. Sequence offsets prevent duplicate primary keys in distributed inserts.
- ✓
Managing DDL replication synchronization to ensure schema modifications match across nodes
Why this is correct
Correct. DDL changes must be replicated carefully to avoid schema drift.
- ✗
Disabling all checkpointing to maximize real-time packet loss tolerance
Why it's wrong here
Incorrect. Checkpointing is required for recovery and reliable checkpoint tracking in GoldenGate.
