Which three statements are true about the cluster file system archiving scheme?
A.
Each node can read only the archived logs written by itself.
B.
Nodes don’t use network to archive files.
C.
Each node can read the archive redo log files of the other nodes.
D.
Each node archives to a uniquely named local directory.
E.
Each node archives to a local directory with the same path on each cluster node.
F.
Each node writes to a single location on the cluster file system while archiving the redo log files.
Explanation:
AB: In a cluster file system each node can only read from and write to its own local file system.
D: Configure each node to write to a local archiving directory that is named the same on each node.

I think that correct answer is BCE
Oracle Automatic Storage Management and Cluster File System Archiving Scheme
If you use a cluster file system, then each node writes to a single location on the cluster file system when archiving the redo log files. Each node can read the archived redo log files of the other nodes
The advantage of this scheme is that none of the nodes uses the network to archive logs.
In the cluster file system scheme, each node archives to a directory that is identified with the same name on all instances within the cluster database

Hi Marc
I would say BCF.
Initialization Parameter Settings for the Cluster File System Archiving Scheme
In the cluster file system scheme, each node archives to a directory that is identified with the same name on all instances within the cluster database (/arc_dest, in the following example). To configure this directory, set values for the LOG_ARCH_DEST_1 parameter, as shown in the following example:

A. Each node can read only the archived logs written by itself.
Wrong:

Alternatively, you can use a cluster file system archiving scheme. If you use a cluster file system, then each node writes to a single location on the cluster file system when archiving the redo log files. Each node can read the archived redo log files of the other nodes.
Advantages of the Cluster File System Archiving Scheme
The advantage of this scheme is that none of the nodes uses the network to archive logs. Because the file name written by a node can be read by any node in the cluster, RMAN can back up all logs from any node in the cluster. Backup and restore scripts are simplified because each node has access to all archived redo logs.
Location of Archived Logs for the Cluster File System Archiving Scheme
Because the file system is shared and because each node is writing its archived redo logs to the /arc_dest directory in the cluster file system, each node can read the logs written by itself and any other node.
B. Nodes don’t use network to archive files.
Right:

ACD is only the correct answer. check the oracle docs https://docs.oracle.com/cd/E11882_01/rac.112/e41960/rman.htm#RACAD324
This is a “cluster file system archiving” and not a “filesystem archiving”, doesn’t have “local directory”, exists only a “shared directory” in a “cluster file system” in this schema, but, good luck!
Yes, you are correct, BCF is the rite choice. thanks
