Answer: A,C
Question: 2
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.You are creating indexes in a data warehouse.You have a dimension table named Table1 that has 10,000 rows. The rows are used to generate several reports.The reports join a column that is the primary key.The execution plan contains bookmark lookups for Table1.You discover that the reports run slower than expected.You need to reduce the amount of time it takes to run the reports.
Solution: You create a nonclustered index on the primary key column that includes the bookmark lookup columns.Does this meet the goal?
A. Yes
B. No
Answer: B
QUESTION 3
Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.
You have a database that is denormalized. Users make frequent changes to data in a primary table. You need to ensure that users cannot change the tables directly, and that changes made to the primary table also update any related tables.What should you implement?
A. the COALESCE function
B. a view
C. a table-valued function
D. the TRY PARSE function
E. a stored procedure
F. the ISNULL function
G. a scalar function
H. the TRY CONVERT function
Answer: B
Explanation:
Using an Indexed View would allow you to keep your base data in properly normalized tables and
maintain data-integrity while giving you the denormalized "view" of that data.

QUESTION 4
You are developing a Microsoft SQL Server database.You create a view that performs the following tasks:Joins 10 tables that contain up to 400,000 records each.
Performs aggregations on 4 fields.The view is frequently used in several detailed reports.You need to improve the performance of the reports. What should you do?
A. Convert the view into a table-valued function
B. Convert the view into an indexed view
C. Convert the view into a stored procedure and retrieve the result from the stored procedure into a
temporary table
D. Convert the view into a Common Table Expression (CTE)
Answer: B
Explanation:
The first index created on a view must be a unique clustered index. After the unique clustered
index has been created, you can create more nonclustered indexes. Creating a unique clustered
index on a view improves query performance because the view is stored in the database in the
same way a table with a clustered index is stored. The query optimizer may use indexed views to
speed up the query execution. The view does not have to be referenced in the query for the
optimizer to consider that view for a substitution.

Microsoft is testing Skype group calls for up to 50 people
Skype conference calls could be about to get a whole lot busier. Microsoft is planning to bump up the maximum number of group call participants from 25 to 50 (18 more than can fit into a Group FaceTime call). The audio and video buttons will be enabled for larger groups, so people can more easily mute their microphones or turn on/off their webcam.
So you don't bother people who can't join a call too much, Skype also plans to make ringing optional. It will instead send a notification to group call participants, though you can still ask Skype to ring people if they don't respond. These features are available as of today for beta testers, and they'll likely roll out more broadly later.

Microsoft Excel adds photo-to-spreadsheet feature with latest update
Microsoft Excel for Android has been updated with a nifty new feature that was originally teased at a conference last year. If you’re in a rush and need to turn a photo or image into a spreadsheet that you can actually edit, this is now your go-to app.
The update uses image recognition and AI to snap a photo of something like a nutrition label, then turn it into a spreadsheet full of data and separated columns for you to edit and manipulate. Early testing seems like it works well, excluding a few hiccups with Excel struggling to see exactly where it should be separating rows of data in some instances.
But in a pinch, this is still much, much faster than trying to input information manually, especially on a smartphone. Even with a few small errors you can iron those things out relatively quickly and get on with whatever it is you need.
This feature is rolling out to beta users of Microsoft 365 first, so you can expect it to make its way to the rest of us once the bugs are ironed out down the line.

You may think the market loves a tech company for what it is, but sometimes the market cares more about a stock’s style. That’s the point of a recent note by Prashant Sundararajan, who heads quant research sales at Nomura Instinet.
In 2018, tech stock performance was driven as much by company-specific events as by the vicissitudes of certain styles—like how growth stocks lost favor in 2018’s last two months. This year, however, Sundararajan finds that the style factors account for all the returns of the leading techs (after adjusting for the moves of the overall market).
“If all your returns are being driven by style bets and industry bets,” says Sundararajan, “you should be cognizant that some of these factors can have large reversals.”
The tech leaders of the long bull market have been the FANGs. You know: Facebook (FB), Apple (AAPL), Amazon.com (AMZN), Netflix (NFLX) and Google parent Alphabet (GOOGL). Sundararajan broadened his study by adding Microsoft (MSFT) and chip maker Nvidia (NVDA), ending up with an equal-weighted set called Fangman.
“I always wondered why Microsoft wasn’t included, and I also wanted a semiconductor stock,” he says. “Besides, Fangman is just a much more interesting name.”
To disassemble the drivers of Fangman returns, Sundararajan carried out a performance attribution—a kind of statistical analysis that breaks performance down into systematic factors and stock-specific ones. A portfolio’s moves are compared against groups of stocks with a certain characteristic, like earnings growth or stock-price momentum. When such correlations are strong and seem to explain most of a portfolio’s moves, then it probably isn’t responding to the fundamentals of its specific stocks, such as individual companies’ earnings or products.
Since early December, the Fangman returns have been entirely driven by the style of stocks they represent, namely: high earnings growth, high variability of earnings, and highly liquid trading.
While Sundararajan isn’t among Nomura’s research analysts who recommend particular stocks, he notes that tech investors might want to hedge their portfolios with stocks that have offsetting style factors. “As quants,” he says, “we want to be as factor-diversified as possible.”

Microsoft to brand Centaurus and Pegasus operating system as ‘Lite
We have heard varying reports about Microsoft’s operating system for a new generation of devices.
Windows Core OS is meant to be the core of a modular operating system with a layer of shells which changes per device, such as Andromeda for Microsoft’s Surface Phone and Aruba for the Surface Hub.
Now a new report by Petri.com suggests Microsoft may be looking at using the same operating on both their dual-screened Centaurus and laptop-focussed Pegasus devices.
The shell will supposedly be very simplified for a one-app-at-a-time experience, though windowing would be allowed, and will supposedly be “modernized, minimal, and refreshed.”
The OS would supposedly be optimised for instant on, battery life, and simplistic updates, and may only run UWP and PWA apps. Microsoft is supposedly intending to separate the OS from legacy Windows by branding it as Lite, not Windows Lite, and will be licensing the OS to OEMs.
The news, if true, is somewhat worrying for two reasons – One, that Microsoft is intending to use the same shell for their dual-screen OS as for their laptop OS, and secondly that by all accounts the OS will be somewhat crippled when it comes to user interface and functionality, which means Microsoft is once again starting over, which invariably leads to failure.
