Subscription1 contains a virtual network VNet1 in resource group RG1. User1 has the Reader, Security Admin, and Security Reader roles. To allow User1 to grant the Reader role on VNet1 to other users, what should you do?

The Owner role grants full access to manage all resources, including the ability to delegate access to others. Therefore, assigning User1 the Owner role for VNet1 will allow them to grant the Reader role on VNet1 to other users. The Network Contributor role allows managing network resources but does not include permission to grant roles. Removing User1 from Security Reader and assigning Contributor to RG1 would give broader permissions than necessary and might not specifically grant role delegation on VNet1 if other permissions are inherited or blocked. Contributor at the resource group level allows managing resources within the group but not necessarily delegating access to specific resources within it.
