HOTSPOT
You have a domain controller that hosts an Active Directory-integrated zone.
On the domain controller, you run the following cmdlet:
PS C:\\> Get-DnsServerScavenging
NoRefreshInterval:2.00:00:00
RefreshInterval:3.00:00:00
ScavengingInterval:4.00:00:00
ScavengingState:True
LastScavengeTime:1/30/2014 9:10:36 AM

Answer: 
Explanation:
First answer
* -NoRefreshInterval<TimeSpan>
Specifies a length of time as a TimeSpan object. NoRefreshInterval sets a period of time in which no
refreshes are accepted for dynamically updated records. Zones on the server inherit this value
automatically.This value is the interval between the last update of a timestamp for a record and the earliest time when
the timestamp can be refreshed. The minimum value is 0. The maximum value is 8760 hours (seven
days).
* Here it is set to 2 days: NoRefreshInterval:2.00:00:00
Second answer
-ScavengingState<Boolean> (In this question it is set to true)
Enables or disables automatic scavenging of stale records. ScavengingState determines whether the DNS
scavenging feature is enabled by default on newly created zones. The acceptable values for this
parameter are:
— $False. Disables scavenging. This is the default setting.
— $True. Enables scavenging
