1Z0-078 practice question 1 of 15

Which three statements are true about ASM Cloud File System (ACFS) replication? (Choose three.)

Full set: 77 questions

Answer options

A: Replication is automatically terminated if the primary file system has less than 2 GB free space.

B: ACFS auditing information is replicated from the primary file system to the standby file system. Correct answer

C: Standby redo log files are required on the standby site for synchronous redo transport.

D: The privilege sysrepl has been introduced for ACFS replication. Correct answer

E: One site of an ACFS replication configuration can host both primary and standby file systems. Correct answer

Correct Answer:

B. ACFS auditing information is replicated from the primary file system to the standby file system.; D. The privilege sysrepl has been introduced for ACFS replication.; E. One site of an ACFS replication configuration can host both primary and standby file systems.

Explanation

ACFS asynchronous replication copies both file data and associated metadata, including audit logs, from the primary to the standby file system. Starting with 12.2, the SYSREPL privilege enables administrators to execute acfsutil replication and disaster-recovery commands without full SYSASM rights. Because replication is configured per-file-system pair, a single site can simultaneously act as primary for one ACFS file system and standby for another, allowing flexible hub-and-spoke or peer configurations.

Why Incorrect

A. Replication stops only when free space is exhausted; no fixed 2 GB threshold is defined in documentation.
C. ACFS replication is independent of Redo transport; standby redo logs are a Data Guard requirement, not needed here.
