Which Three Statements Are True About Oracle RAC Installation?

1Z0-078 By islever Editorial Last updated

Pre-installation tasks and requirements Install and configure Oracle Clusterware

Short answer

ABE Oracle RAC installation permits SSH equivalence setup (A), requires root-run fix-up scripts on UNIX (B), and needs Enterprise Edition (E).

Question

Which three statements are true about an Oracle Database RAC software installation? (Choose three.)
  1. SSH user equivalence for the Oracle user can be set up before the software installation. Correct Answer
  2. Fix-up scripts generated during the installation must be run as root on UNIX platforms. Correct Answer
  3. The software must be installed into a local file system on each node.
  4. The software must be installed into a cluster file system.
  5. RAC installations require Oracle Enterprise Edition. Correct Answer

Key Takeaways

Tests knowledge of Oracle RAC installation prerequisites and post-installation steps, with the trap being that RAC does not require a local or cluster file system for the software home.

This question tests three true statements about Oracle RAC software installation, covering SSH user equivalence, fix-up scripts, and edition requirements. The correct answers are A, B, and E, as RAC requires Enterprise Edition and follows specific pre-installation and root script execution steps.

Common mistake: Many candidates select option F (not listed) or believe Standard Edition 2 supports RAC, but Oracle RAC requires Enterprise Edition under standard licensing.

Expert Analysis

Why the Answer Is Correct

The correct statements are A, B, and E. Option A is true because SSH user equivalence for the Oracle user can be established before running the installer; this connectivity is required for remote operations during RAC installation. Option B is true because fix-up scripts generated during installation—typically for missing OS packages or kernel parameters—must be executed as root on UNIX/Linux platforms. Option E is true because Oracle RAC is an Enterprise Edition feature; Oracle Database 19c licensing documentation states RAC is available only with Enterprise Edition. These three statements reflect Oracle's official installation and licensing requirements for 1Z0-078.

Why the Other Options Are Wrong

Option C is false because Oracle RAC software does not have to be installed into a local file system on each node; a shared Oracle home on a cluster file system is supported and often recommended. Option D is false because the software does not have to be installed into a cluster file system; local (non-shared) Oracle homes are fully supported for RAC database software. Both options present a "must" condition that contradicts Oracle's flexible deployment choices.

Community Comment Notes

Community comments reveal confusion. lcoleandro lists A, E, and F as correct, where F refers to ACFS support for the shared Oracle home. Jaroslav113 wrote "ABF, E is wrong, Standard Edition is possible as well," arguing that Standard Edition 2 supports RAC. However, Oracle's 19c licensing documentation confirms RAC is Enterprise Edition only, so E remains true for this exam. The missing option F in this question explains the split, but among A–E, the three true statements are A, B, and E.

Exam Strategy

For multi-select questions on RAC installation, validate each statement against Oracle's official documentation. Remember that 'must' statements are often false because Oracle supports multiple valid configurations, such as local or shared Oracle homes. Always check edition requirements, as RAC remains an Enterprise Edition feature in 19c.

Frequently Asked Questions

Why is option B true for RAC installation?

Fix-up scripts are generated when the installer detects missing OS prerequisites, and on UNIX/Linux they must be run as root to apply the fixes.

Does Oracle RAC require Enterprise Edition in 19c?

Under standard Oracle licensing, yes—RAC is an Enterprise Edition option. Some engineered systems may allow SE2 with RAC, but 1Z0-078 expects Enterprise Edition.

    ABF correct, Rac 19c is support standart edition 2.

    Correct Statements: A. Necessary for passwordless SSH connectivity between nodes during installation. E. Oracle RAC is a feature of the Enterprise Edition, not available in the Standard Edition. F. Oracle ACFS (ASM Cluster File System) is supported for RAC installations. Incorrect Statements: B. Fix-up scripts are related to configuration checks and prerequisites, not directly a part of the RAC software installation. C. RAC software is typically installed in shared storage, not local file systems. D. While shared storage is required, it doesn't have to be a traditional cluster file system; ASM is also supported. G. This implies local installations on each node, which is not accurate as RAC is installed on shared storage.
