1Z0-997-26 Databases Practice Question

When designing a multi-database architecture with Oracle GoldenGate for high availability and load distribution, which THREE architectural considerations are critical for success? (Choose three.)

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.
