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
