ReadWriteMany -
E
ReadWriteOnce,ReadOnlyMany
Reveal correct answer
Correct answer: E
A.
ReadWriteOncePod allows a Persistent Volume to be used as read-write by a single Pod, but it doesn't facilitate the scenario of read-only by multiple nodes.
B.
ReadWriteOnce alone only allows the Persistent Volume to be mounted as read/write by a single node. It does not allow for the read-only mounting by multiple nodes.
C.
ReadOnlyMany alone allows for the volume to be mounted as read-only by multiple nodes, but it does not allow for read/write mounting by a single node.
D.
ReadWriteMany allows the volume to be mounted as read/write by multiple nodes, but it doesn't allow for the combination of read/write by one node and read-only by many nodes.
E.
Using both ReadWriteOnce and ReadOnlyMany as access modes would satisfy the requirement. ReadWriteOnce allows the Persistent Volume to be mounted as read/write by a single node. ReadOnlyMany allows the Persistent Volume to be mounted as read-only by multiple nodes. Thus, using these two modes together would allow the volume to be mounted as read/write by a single node and as read-only by many nodes.
