Which four methods can be used to add it to the services repository?

There is a valid SMF manifest located underneath the /var/svc/manifest directory.
Which four methods can be used to add it to the services repository?

A.
Reboot the system.

B.
Restart the early-manifest-import service.

C.
Use the svccfg apply command.

D.
Restart the manifest-import service.

E.
Use the svccfg import command.

Explanation:
AD: Manifests from the standard directory trees /lib/svc/manifest and
/var/svc/manifest are processed during system boot and anytime an administrator or program
runs:
$ svcadm restart manifest-import
C: svccfg
apply subcommand
If the argument is a service profile or manifest, apply the configuration to the admin layer of the
SMF repository. Services, instances, property groups, and properties will be created as necessary.
E: import [-V] [file | directory]
svccfg import on a file in a system-managed filesystem location (subdirectories of /lib/svc/manifest
and /var/svc/manifest) invokes: svcadm restart manifest-import.
Placing your manifests in a system-managed location and invoking svcadm restart manifest-import
to import them is the recommended practice.
svccfg import on files in other locations imports their properties as administrative customization
into the admin layer. It is equivalent to:

svccfg apply [file | directory]
Incorrect:
not B: Manifests are processed in two different phases during boot.
The service svc:/system/early-manifest-import:default, a pseudo service, is responsible for the first
manifest processing. This service processes only manifests from the /lib/svc/manifest directory
tree before svc.startd(1M) initializes any services thus enabling services delivered in
/lib/svc/manifest to always start with their most updated definition. Since this is a pseudo service,
svcadm(1M) commands are ignored though svcs(1) can be used to observe status and get log file
information.
The svc:/system/manifest-import:default service handles the second manifest processing and
imports manifest files from both /lib/svc/manifest and /var/svc/manifest directory trees, in that
respective order.
