A user’s workstation is configured to mount /archive from a remote system through NFS using the following entry in /etc/vfstab:

#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
speedy:/archive – /archive nfs – yes –

To improve performance, a second NFS server, named pokey, is being added to serve out the identical file system.
You notice that the workstation is attempting to mount /archive read-write. The /archive file system contains old archived data and should not be modified. You decide that the user’s workstation should mount /archive read-only instead.

Which two changes must you make to allow the workstation to use the NFS server pokey and speedy and to correct the read-write/read-only mounting issue? (Choose two.)

A.
change the mount options field to ro

B.
change the mount options field to ro=speedy,pokey

C.
change the device to mount field to speedy,pokey:/archive

D.
change the device to mount field to read pokey:/archive/speedy
