Question 56

You are going to use the- Automated installer (AI) to install a non global zone named zone1. You have created a custom manifest for the non-global zone and named it zone1manifest
Which command will you use to add this custom manifest to the s11-sparc install service and associate this custom manifest with the non-global zone?

A. installadm create-profile -n s11-sparc -f /tmp/zone1manifest.xml - c

B. installadm create-manifest -n s11-sparc -f /tmp/zone1manifest.xml -m

C. installadm create-client -n s11-sparc -f /tmp/zone1manifest.xml -m zone1manifest -c zonename= “zone1”

D. installadm create-service - n s11-sparc -f /tmp/zone1manifest.xml -m zone1manifest - c zonename=”zone1”

Correct Answer:B
