An administrator is planning a two node cluster containing Node1 and Node2 with a single resource groupnamed RG1. RG1 startup policy will be ’Online on Home Node only’. The home node is Node1. If RG1 fails over to Node2 itmust fall back to Node1. Fall back must take place outside of business hours. The agreed time for fall back is20：00. How will this be achieved with minimum action taken by administrator？（） ["Configure the resource group with a fallback policy of "Fallback to Higher Priority Node" Restart Node1 at20：00","Configure the resource group with a fallback policy of "Never Fallback" Manually move the resource groupfrom Node2 to Node1 at 20：00","Configure the resource group with a fallback policy of "Fallback To Higher Priority Node" Create a"Delayed Fallback Timer" policy to meet the requirements Allocate this delayed timer policy to theresource group RG1","Configure the resource group with a fallback policy of "Never Fallback" Create a "Delayed Fallback Timer"policy to meet the requirement Specify this delayed timer policy as a "Fallback Override" to the resourcegroup RG1"]
