The GetVendors() action in the ProcessedOrderController controller is querying the database each time it is
run. The GetVendors() action must query the database only if the cache is null.
You need to add code to the action at line PC33 to cache the data.
Which code segment can you use? (Each correct answer presents a complete solution. Choose all that apply.)

• A.cache.Add("vendors", vendors, new CacheItemPolicy());
• B.cache.Add(new CacheItem("vendorKey", vendors) , GetVendorPolicy());
• C.cache.Set(new CacheItem("vendorKey", vendors), GetVendorPolicy());
• D.cache.AddOrGetExisting("vendorKey", context, new CacheItemPolicy());

Historical flight information data will be stored in Windows Azure Table Storage using the FlightInfo class as
the table entity.
There are millions of entries in the table. Queries for historical flight information specify a set of airlines to
search and whether the query should return only late flights. Results should be ordered by flight name.
You need to specify which properties of the FlightInfo class should be used at the partition and row keys to
ensure that query results are returned as quickly as possible.
