You need to meet the security requirement for site collection upgrades. Which two Windows PowerShell cmdlets should you perform? (Each correct answer presents part of the solution. Choose two.)

Setting $reports.AllowSelfServiceUpgrade = false disables the self-service upgrade option on the site collection, satisfying the security requirement that prevents end users from initiating their own upgrades.

Get-SPSite retrieves the SPSite object for the specific site collection URL, which is required before any property of that site collection can be read or modified in PowerShell.

SPSite.AllowSelfServiceUpgrade is a .NET property reference, not a PowerShell cmdlet, and cannot be executed standalone in a script.

Get-SPWebApplication retrieves a web application object, not a site collection - AllowSelfServiceUpgrade is a property of SPSite, not SPWebApplication.

Setting AllowSelfServiceUpgrade = true would enable self-service upgrades, which is the opposite of the stated security requirement to restrict them.
