Something is wrong, I think it’ll be
CREATE …
SELECT …
GROUP …
CREATE UNIQUE CLUSTERED …
Yep, your answer is good.
Yes I think this is the correct answer
Yes it is correct . The answer given in explanation is wrong. you cant use aggregate ( SUM/Count) without grouping by . it will hits run time error in query browser.

The GROUP BY clause must be included. There’s no need to create a UNIQUE INDEX on customerID column of the view when a UNIQUE CLUSTERED INDEX will be even more efficient on the same column.
The SELECT statement in the view definition must contain the following Transact-SQL elements:
**If GROUP BY is present, the VIEW definition must contain COUNT_BIG(*) and must not contain HAVING. These GROUP BY restrictions are applicable only to the indexed view definition. A query can use an indexed view in its execution plan even if it does not satisfy these GROUP BY restrictions.
**If the view definition contains a GROUP BY clause, the key of the unique clustered index (CustomerID) can reference only the columns specified in the GROUP BY clause (CustomerID, CustomerName).

Same Question on 70-461, Q 76. this is a wrong answer.
The Unique Index statement is not correct b/c the first index on a view has to be a unique clustered index since the view itself does not store any data.
The best thing about SQL Server is you can test it the answers and i just did this and here is what i found:
CREATE VIEW SalesLT.vwCustomerRevenue
WITH SCHEMABINDING
AS
SELECT
SO.CustomerID, C.FirstName +’ ‘+c.LastName AS CustomerName, SUM(so.SubTotal) AS CustomerTotal, COUNT_BIG(*) as RecCount
FROM SalesLT.Customer AS C inner join SalesLT.SalesOrderHeader AS SO
ON C.CustomerID = SO.CustomerID
GROUP BY so.CustomerID, C.FirstName +’ ‘+c.LastName
—-Succeeded
If you remove the GROUP BY clause then it fails as mentioned above so the GROUP BY is mandatory
CREATE UNIQUE CLUSTERED INDEX idx_vwCustomerRevenue ON SalesLT.vwCustomerRevenue (CustomerID);
–Surprisingly i didnt expect this to work but it did using CustomerID only
The last CREATE UNIQUE INDEX is using the same index name hence it would fail so only one of them is to be chosen

NEW QUESTION 174
You plan to write a query for a new business report that will contain several nested queries. You need to ensure that a nested query can call a table-valued function for each row in the main query. Which query operator should you use in the nested query?
A. CROSS APPLY
B. INNER JOIN
C. OUTER JOIN
D. PIVOT
Answer: A
Explanation:
The APPLY operator allows you to invoke a table-valued function for each row returned by an outer table expression of a query. The table-valued function acts as the right input and the outer table expression acts as the left input. The right input is evaluated for each row from the left input and the rows produced are combined for the final output. The list of columns produced by the APPLY operator is the set of columns in the left input followed by the list of columns returned by the right input. There are two forms of APPLY: CROSS APPLY and OUTER APPLY. CROSSAPPLY returns only rows from the outer table that produce a result set from the table-valued function. OUTER APPLY returns both rows that produce a result set, and rows that do not, with NULL values in the columns produced by the table-valued function.
NEW QUESTION 175

NEW QUESTION 176
You are a database developer of a Microsoft SQL Server database. You are designing a table that will store Customer data from different sources.

NEW QUESTION 177
Drag and Drop Question
You maintain a SQL Server database that is used by a retailer to track sales and salespeople. The database includes two tables and two triggers that is defined by the following Transact-SQL statements:
Image URL: passleader.org/wp-content/uploads/2017/05/passleader-70-461-dumps-1771.jpg
During days with a large sales volume, some new sales transaction fail and report the following error:
Arithmetic overflow error converting expression to data type int.
You need to ensure that the two triggers are applied once per sale, and that they do not interfere with each other. How should you complete the relevant Transact-SQL statement? To answer, drag the appropriate Transact-SQL segments to the correct location or locations. Each Transact-SQL segment 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.

Answer:
Image URL: passleader.org/wp-content/uploads/2017/05/passleader-70-461-dumps-1773.png
Explanation:
Box 1: OFF
Box 2: 0
Only direct recursion of AFTER triggers is prevented when the RECURSIVE_TRIGGERS database option is set to OFF. To disable indirect recursion of AFTER triggers, also set the nested triggers server option to 0.
Note:
Both DML and DDL triggers are nested whena trigger performs an action that initiates another trigger. These actions can initiate other triggers, and so on. DML and DDL triggers can be nested up to 32 levels. You can control whether AFTER triggers can be nested through the nested triggers server configuration option. If nested triggers are allowed and a trigger in the chain starts an infinite loop, the nesting level is exceeded and the trigger terminates.
