Which command should you use?

You are migrating to Cloud DNS and want to import your BIND zone file.

Which command should you use?

A. gcloud dns record-sets import ZONE_FILE –zone MANAGED_ZONE
B. gcloud dns record-sets import ZONE_FILE –replace-origin-ns –zone MANAGED_ZONE

C. gcloud dns record-sets import ZONE_FILE –zone-file-format –zone MANAGED_ZONE

D. gcloud dns record-sets import ZONE_FILE –delete-all-existing –zone MANAGED ZONE

Explanation:
Once you have the exported file from your other provider, you can use the gcloud dns record-sets import command to import it into your managed zone.
To import record-sets, you use the dns record-sets import command. The –zone-file-format flag tells importto expect a BIND zone formatted file. If you omit this flag, import expects a YAML-formatted records file.
