Question: 1

Note: This question is part of a series of questions that use the same scenario. For your convenience, the
scenario is repeated in each question. Each question presents a different goal and answer choices, but
the text of the scenario is exactly the same in each question in this series.
You have a Microsoft SQL Server data warehouse instance that supports several client applications.
The data warehouse includes the following tables: Dimension.SalesTerritory, Dimension.Customer,
Dimension.Date, Fact.Ticket, and Fact.Order. The Dimension.SalesTerritory and Dimension.Customer
tables are frequently updated. The Fact.Order table is optimized for weekly reporting, but the company
wants to change it daily. The Fact.Order table is loaded by using an ETL process. Indexes have been
added to the table over time, but the presence of these indexes slows data loading.
All data in the data warehouse is stored on a shared SAN. All tables are in a database named DB1. You
have a second database named DB2 that contains copies of production data for a development
environment. The data warehouse has grown and the cost of storage has increased. Data older than one
year is accessed infrequently and is considered historical.
You have the following requirements:
You are not permitted to make changes to the client applications.
You need to optimize the storage for the data warehouse.
What change should you make?

A. Partition the Fact.Order table, and move historical data to new filegroups on lower-cost storage.
B. Create new tables on lower-cost storage, move the historical data to the new tables, and then shrink
the database.
C. Remove the historical data from the database to leave available space for new data.
D. Move historical data to new tables on lower-cost storage.

Answer: A

Explanation:
Create the load staging table in the same filegroup as the partition you are loading.
Create the unload staging table in the same filegroup as the partition you are deleteing.
From scenario: Data older than one year is accessed infrequently and is considered historical.

Question: 2

Note: This question is part of a series of questions that use the same scenario. For your convenience, the
scenario is repeated in each question. Each question presents a different goal and answer choices, but
the text of the scenario is exactly the same in each question in this series.
You have a Microsoft SQL Server data warehouse instance that supports several client applications.
The data warehouse includes the following tables: Dimension.SalesTerritory, Dimension.Customer,
Dimension.Date, Fact.Ticket, and Fact.Order. The Dimension.SalesTerritory and Dimension.Customer
tables are frequently updated. The Fact.Order table is optimized for weekly reporting, but the company
wants to change it daily. The Fact.Order table is loaded by using an ETL process. Indexes have been
added to the table over time, but the presence of these indexes slows data loading.
All data in the data warehouse is stored on a shared SAN. All tables are in a database named DB1. You
have a second database named DB2 that contains copies of production data for a development
environment. The data warehouse has grown and the cost of storage has increased. Data older than one
year is accessed infrequently and is considered historical.
You have the following requirements:
Implement table partitioning to improve the manageability of the data warehouse and to avoid the need
to repopulate all transactional data each night. Use a partitioning strategy that is as granular as possible.
Partition the Fact.Order table and retain a total of seven years of data.
Partition the Fact.Ticket table and retain seven years of data. At the end of each month, the partition
structure must apply a sliding window strategy to ensure that a new partition is available for the
upcoming month, and that the oldest month of data is archived and removed.
Optimize data loading for the Dimension.SalesTerritory, Dimension.Customer, and Dimension.Date
tables.
Incrementally load all tables in the database and ensure that all incremental changes are processed.
Maximize the performance during the data loading process for the Fact.Order partition.
Ensure that historical data remains online and available for querying.
Reduce ongoing storage costs while maintaining query performance for current data.
You are not permitted to make changes to the client applications.
You need to implement the data partitioning strategy.
How should you partition the Fact.Order table?

A. Create 17,520 partitions.
B. Use a granularity of two days.
C. Create 2,557 partitions.
D. Create 730 partitions.

Answer: C

Explanation:
We create on partition for each day. 7 years times 365 days is 2,555. Make that 2,557 to provide for leap
years.
From scenario: Partition the Fact.Order table and retain a total of seven years of data.
Maximize the performance during the data loading process for the Fact.Order partition.

Microsoft says facial recognition firm that Beijing allegedly uses to track Muslims is lying about a 'partnership'

• Microsoft has denied any partnership with controversial Chinese facial recognition app SenseNets.
• SenseNets' facial recognition technology is allegedly being used by the Chinese government to track the country's minority Uighur Muslim population in Xinjiang province.
• SenseNets has listed Microsoft as a partner on its website but the U.S. firm is saying that its logo is being used "without permission."
• Arjun Kharpal | @ArjunKharpal
• Published 20 Hours Ago  Updated 18 Hours Ago
• CNBC.com
• Microsoft CEO Satya Nadella
• Justin Sullivan/Getty Images
• Microsoft CEO Satya Nadella
• Microsoft denied that it has any connection with a controversial Chinese facial recognition app that rights groups say is being used by Beijing to track minority Muslims in China.

The company, called SenseNets, sells facial recognition and crowd analysis technology that is designed to detect unusual behavior in large groups of people, according to its website.

SenseNets suffered a data leak in February which was discovered by security researcher Victor Gevers. He revealed that personal information on 2.5 million people tracked by the company was publicly available. Gevers found that most of the records were collected in China's Xinjiang province, a region in the west of China with a large population of minority Uighur Muslims.

"We have been made aware SenseNets is using our logo on its website without our permission, and we have asked for it to be removed.

• Various rights groups have urged the United Nations to carry out a fact-finding mission in Xinjiang. The U.S. State Department weighed in on Thursday on China's human rights violations against Muslims in Xinjiang, calling it "great shame for humanity."
• The Chinese government has consistently denied any wrongdoing with regard to the Uighurs.
• SenseNets did not respond to three attempts by CNBC this week to contact the company.
• Reports suggest that facial recognition is part of a wide-scale surveillance program in the region that also includes the collection of people's DNA samples.
• SenseNets, which is involved in the facial recognition aspect of the program, lists Microsoft on its website under its "partners" section.

The U.S. software giant denied any involvement with the company.

"Microsoft is not involved in a partnership with SenseNets. We have been made aware SenseNets is using our logo on its website without our permission, and we have asked for it to be removed," a spokesperson for the company told CNBC on Friday.

Microsoft sells software for facial recognition based on its cloud product Azure. Third parties can purchase Microsoft's software for use in their own applications. But Microsoft said it has no relationship with SenseNets.

The company's denial comes after Gevers posted a screenshot of code from SenseNets software. It shows a line of code appearing to be tied to Microsoft's facial recognition tool.

It has been 22 days after our initial report about the SenseNets incident. I decided to start investigating the strategic & technical partners from Silicon Valley that contribute to "face recognition" part of this system. Within a few days, I'm going to share some new insights.

Gevers told CNBC on Friday that the Microsoft code could have been present because an individual developer brought it and paid for it themselves or used a free trial. This means there would be no trace back to SenseNets.

CNBC asked Microsoft to clarify whether SenseNets could have access to its tool without paying for it or without the company's knowledge. Microsoft did not immediately respond to that inquiry.

Microsoft has tried to lead the responsible development of artificial intelligence.

In January, CEO Satya Nadella called for regulation on facial recognition technology. Microsoft has a six-point manifesto that it says guides its facial recognition work. One of those points is "lawful surveillance," in which it advocates for "safeguards for people's democratic freedoms in law enforcement surveillance scenarios."

Microsoft has said it will "not deploy facial recognition technology in scenarios that we believe will put these freedoms at risk."

Microsoft's New Android Vision Feature Will Power Up Excel

In theory, this should allow users to take a picture of something that looks a bit like a grid or table, Microsoft’s artificial intelligence code will take the input and you’ll get a workable Excel spreadsheet of the data in the image. Think of it like OCR but for columns and rows. Here’s how Microsoft describes it in a blog post:

Open Excel on your phone or tablet and tap the Insert data from picture button to get started

Next, narrow in on your data until you see it surrounded by a red border, then tap the capture button. If needed, you can use the sizing handles around the edges of the image to crop it to size first.

Excel's powerful AI engine will process the image and convert it to a table. When it first imports your data, it will give you a chance to correct any issues it discovered during the conversion process.

On its own, not a stunning must heave feature. But it continues to promote a number of ideas that are key to Microsoft’s recalibrated mobile ambitions. This is not an easy task to accomplish. Scanning for a grid or outline can be done by many apps (including Microsoft’s own Office Lens) but taking the visual data and building up the sheet is the ‘simple magic’ that smartphone users love.

It wraps up this feature in the subscription based Office 365 package, which is turning out to be a key driver of revenue and customer engagement.

Finally, while this feature is still in beta for a limited number of Android users, you can be sure that when it gets a full release it will be cross-platform. That will allow Microsoft to continue emphasising that the platform is not necessarily the operating system, but the software you choose to run, software that will run on any device no matter the underlying OS.

Employees at Microsoft on Friday demanded that the company cancel a contract to supply its augmented-reality headsets to the U.S. Army, warning in a letter that putting HoloLens in the military’s hands could “help people kill.”

Writing to chief executive Satya Nadella, more than 50 workers said the devices would be “turning warfare into a simulated ‘video game.’” They also urged Microsoft, which won the $480 million contract in November, to “cease developing any and all weapons technologies” for the government.

“As employees and shareholders we do not want to become war profiteers,” the letter concluded. “To that end, we believe that Microsoft must stop in its activities to empower the U.S. Army's ability to cause harm and violence.”

A Microsoft spokesman said, “We always appreciate feedback from employees and have many avenues for employee voices to be heard.” The Army did not respond to a request for comment.


A Microsoft employee who helped draft the letter — speaking on the condition of anonymity out of concerns about retribution — shared a copy with The Washington Post and verified that the co-signers work at the company.

The internal revolt at Microsoft highlights the heightened activism among employees at tech giants and follows similar uprisings at Amazon and Google, where workers have bristled over their companies’ business relationships with the U.S. military or law enforcement agencies. Google, for example, opted last year against renewing one of its contracts with the Pentagon — a partnership to develop image-recognition tools for drones — because employees felt that the tech giant shouldn’t be in the “business of war,” they said at the time.

Like its peers, Microsoft has struggled to balance its relationship with the Defense Department against its employees’ ethical and policy qualms about working with the U.S. government.

Last year, after workers petitioned the company to cancel a cloud computing and artificial-intelligence contract with U.S. Immigration and Customs Enforcement, Microsoft said it would allow employees to change positions within the company if they thought their existing roles betrayed their values. But Brad Smith, president of Microsoft, has said the company will not cease working with the Defense Department, a business relationship that he said dates back decades.

“As we have discussed these issues with governments, we’ve appreciated that no military in the world wants to wake up to discover that machines have started a war,” Smith wrote in an October blog post. “But we can’t expect these new developments to be addressed wisely if the people in the tech sector who know the most about technology withdraw from the conversation.”

Microsoft’s early marketing positioned the HoloLens as a “mixed reality” consumer device that architects, artists, video gamers and others could use to transpose computer graphics into real life. The holographic system is now being sold to developers and businesses, but is not yet available for public use. Microsoft is expected to unveil a new version of its HoloLens headset at a major industry trade show in Barcelona next week.


Last year, the headset proved to be the clincher for Microsoft to beat out two dozen other companies, including military contractors Lockheed Martin and Raytheon and the tech start-up Magic Leap, for the Army contract. The military said it could end up buying more than 100,000 of the systems in the coming years.

The Defense Department in August issued a request for an “Integrated Visual Augmentation System” for training and combat that would give soldiers “increased lethality, mobility and situational awareness . . . against our current and future adversaries,” military purchasing records show.

The military said it wanted a heads-up display system that could supercharge soldiers’ capabilities: giving them heat detection, night vision ,and the ability to view video and navigation; automatically recognizing and targeting “relevant threats”; and allowing them to stealthily see where their weapons were aiming, without using a laser that could give their location away.

The military also wanted the system to quickly identify land mines and improvised explosives and relay back real-time “squad lethality metrics” and health data, such as soldiers’ heart rates, breathing rates and whether they’ve sustained a concussion. The headset could also be used as part of an advanced simulation system that would “train units where they will fight (and) with whom they will fight,” contract documents show

Microsoft starts testing a version of Windows 10 it won’t release until 2020

• Microsoft has started testing an update to Windows 10 that it plans to release in 2020. It’s unusual for the company to test updates so far in advance, as Microsoft typically releases two updates per year and tests them with members of the public. Microsoft has not yet started testing its next 2019 update, codenamed 19H2, but Microsoft’s Windows Insider chief, Dona Sarkar, says additional testing is required for this new 2020 update.

• Due in the first half of 2020, and codenamed 20H1, Sarkar says “some things we are working on in 20H1 require a longer lead time.” Microsoft has not yet officially unveiled features for this update, but the company has released the first early beta build of it to testers today. Windows 10 build 18836 has been released to testers who opt into the Skip Ahead ring for future versions of Windows, and Microsoft will start testing its 19H2 update later this spring.

• Microsoft is currently in the process of finalizing its next major Windows 10 update, due in April. It’s currently codenamed 19H1, and the software maker is expected to ship a final version of it to testers in March before making it more broadly available to existing machines. This spring 2019 update will include a new light theme, Kaomoji support, a separation of Cortana from Windows search, and a new built-in Office app
