No you don’t - but if you put in the line in fstab - you must ensure the share is not mounted until the network is up and the NAS is available.
The naming is a remnant from the first reverse engineering done on the proprietary Microsoft CIFS (Common Internet File System) which later was renamed to SMB and is still a proprietary Microsoft filesharing protocol.
The Linux Samba project is still reverse engineered from proprietary SMB (Microsoft).
I have SMB shares running of a Linux box - I mount it using systemd mount- and automount units.
I have lately reworked the my topic with sample mount units and I can guarantee they are working and I have no problems with transfer rates over the wire.
The sample units can be found in the following topic
Setting up fstab can be very confusing and error prone whereas the mount units is easier to work with.
I know - fstab is a mantra - because everything circles around fstab.
When you use a modern EFI booted computer and a systemd based distribution like Manjaro it is possible - if your setup is not complicated - to completely ignore fstab - and your system will work anyway.
You can mount remote filesystems and devices using systemd - and it is done on the fly - silently connection and disconnecting in the background.
