Q12. DRAG DROP - (Topic 1) 

You are developing an application that implements a set of custom exception types. You declare the custom exception types by using the following code segments: 

The application includes a function named DoWork that throws .NET Framework exceptions and custom exceptions. 

The application contains only the following logging methods: 

The application must meet the following requirements: 

. When AdventureWorksValidationException exceptions are caught, log the information by using the static void Log (AdventureWorksValidationException ex) method. 

. When AdventureWorksDbException or other AdventureWorksException exceptions are caught, log the information by using the static void I oq( AdventureWorksException ex) method. 

You need to meet the requirements. 

How should you complete the relevant code? (To answer, drag the appropriate code segments to the correct locations in the answer area. Each code 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:


Q16. DRAG DROP - (Topic 1) 

You are developing a custom collection named LoanCollection for a class named Loan class. 

You need to ensure that you can process each Loan object in the LoanCollection collection by using a foreach loop. 

How should you complete the relevant code? (To answer, drag the appropriate code segments to the correct locations in the answer area. Each code 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: 


Q17. - (Topic 2) 

You are implementing a method named GetValidPhoneNumbers. The GetValidPhoneNumbers() method processes a list of string values that represent phone numbers. 

The GetValidPhoneNumbers() method must return only phone numbers that are in a valid format. 

You need to implement the GetValidPhoneNumbers() method. 

Which two code segments can you use to achieve this goal? (Each correct answer presents a complete solution. Choose two.) 

A. Option A 

B. Option B 

C. Option C 

D. Option D 

Answer: A,B 

Explanation: * Regex.Matches Searches an input string for all occurrences of a regular expression and returns all the matches. 

* MatchCollection 

Represents the set of successful matches found by iteratively applying a regular 

expression pattern to the input string. 

The collection is immutable (read-only) and has no public constructor. The Regex.Matches 

method returns a MatchCollection object. 

* List<T>.Add Method 

Adds an object to the end of the List<T>. 


Q18. DRAG DROP - (Topic 1) 

You are developing an application by using C#. The application includes an array of decimal values named loanAmounts. You are developing a LINQ query to return the values from the array. 

The query must return decimal values that are evenly divisible by two. The values must be sorted from the lowest value to the highest value. 

You need to ensure that the query correctly returns the decimal values. 

How should you complete the relevant code? (To answer, drag the appropriate code segments to the correct locations in the answer area. Each code 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.)
