There is a database which is named Sellings in the instance. The Sellings database contains a table named Productions. The table is used to stores information about all types of products. The Productions table is often queried by users on the basis of the RadioSize column. The RadioSize column contains the NULL value for all products other than Radios. Currently no index exists on the RadionSize column. According to the requirement of the company CIO, you have to optimize the query performance and reduce the effect on the disk space to the least.

The DNS servers in the branch offices host a secondary for the zone. Each branch office has an application server. Users access the application server by using its fully qualified domain name. you need to ensure that users in the branch office can access their local application server even if the WAN links are down for three days. What should you do?（） ["Increase the expires after setting to 4 days on the start of authority (SOA) record for the zone.","Increase the refresh interval setting 0 4 days on the start of authority (SOA) record for the zone.","Configure the zone aging \/ scavenging properties dialog box to enable scavenge state resource records, and set the refresh setting to 4 days.","Configure the zone aging \/ scavenging properties dialog box to enable scavenge state resource records, and set NO-refresh interval setting to 4 days."]
