You are developing the following applications. All applications will be hosted in Azure and data will be stored
using Azure storage.
All data must be stored using the binary large object (blob) hot storage tier.
You need to select the blob storage type for each application.
Which blob storage types should you use? To answer, drag the appropriate blob types to the correct
applications. Each blob type may be used once, more than once, or not at all. You may need to drag the split
bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Box 1 Logging: append blob
An append blob is comprised of blocks and is optimized for append operations. When you modify an append
blob, blocks are added to the end of the blob only, via the Append Block operation.
Box 2 VM Manager: block blob
Block blobs let you upload large blobs efficiently.
Box 3: Accounting: page blob
Page blobs are a collection of 512-byte pages optimized for random read and write operations.

問題6
ReportApp will shut down every night. However, data from the searches performed during the night must still
be collected.
You need to identify the return types for the car year, price, brand and model. The solution must minimize the
number of round trips between the clients and the web servers.
What should you identify? To answer, drag the appropriate return types to the correct objects. Each return type
may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to
view content.

正確答案:
Explanation
Note: A round trip occurs when an object is deserialized and re-serialized in one operation.
From scenario: The application will provide users with the ability to search for a car by using advanced
filtering options, such as the car brand, model, year, and price. All of this information will be stored as strings
and will be displayed as drop-down lists.
The brand and model lists that will be displayed on the home page of the web application will be retrieved
from Windows Communication Foundation (WCF) services hosted in the on-premises environment.
Target 1: Task<String>
Though Performance blocking and Sluggishness are the tailbacks for any application, we can easily overcome
these bottlenecks by using asynchronous programming. But old-style practice for asynchronous programming
is not way easy enou

問題7
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.
What should you do? (To answer, drag the appropriate properties to the correct location or locations in the
answer area. Each property may be used once, more than once, or not at all. You may need to drag the split bar
between panes or scroll to view content.)
