Explanation

Migrating from Direct Routing to Operator Connect requires dismantling the existing Direct Routing configuration before applying the new one. Setting -OnPremLineURI to $null (A) clears the Direct Routing phone number assignment from each user - without this step, the user remains tied to the old trunk. Granting a voice routing policy set to $null (C) removes the Direct Routing voice routing policy, which is unnecessary (and would conflict) in an Operator Connect model where routing is managed by the carrier. Setting the -TelephoneNumber parameter via Set-CsOnlineVoiceUser (D) assigns the carrier-managed Operator Connect number to each user, completing the migration.

Why the distractors are wrong: Option F is the inverse of A - setting -OnPremLineURI to the user's number would re-apply Direct Routing configuration rather than remove it. Options B and E are incomplete in the question text and do not represent valid, complete commands.

Memory tip: Think "Null → Null → Number" - you null out the line URI (A), null out the routing policy (C), then assign the new number (D). The two nulls tear down Direct Routing; the number assignment builds up Operator Connect.
