Q111. - (Topic 2)
You write the following method (line numbers are included for reference only):
You need to ensure that the method extracts a list of URLs that match the following pattern:
@http://(www.)?([^.]+).com;
Which code should you insert at line 07?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: A
Explanation: * 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>. Incorrect: Not D: ICollection.SyncRoot Property For collections whose underlying store is not publicly available, the expected implementation is to return the current instance. Note that the pointer to the current instance might not be sufficient for collections that wrap other collections; those should return the underlying collection's SyncRoot property.
Q112. - (Topic 1)
You are developing an application by using C#.
You have the following requirements:
Support 32-bit and 64-bit system configurations.
Include pre-processor directives that are specific to the system configuration.
Deploy an application version that includes both system configurations to testers.
Ensure that stack traces include accurate line numbers.
You need to configure the project to avoid changing individual configuration settings every time you deploy the application to testers.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Update the platform target and conditional compilation symbols for each application configuration.
B. Create two application configurations based on the default Release configuration.
C. Optimize the application through address rebasing in the 64-bit configuration.
D. Create two application configurations based on the default Debug configuration.
Answer: B,D
Q113. - (Topic 1)
You are developing an application by using C#.
The application includes an object that performs a long running process.
You need to ensure that the garbage collector does not release the object's resources until
the process completes.
Which garbage collector method should you use?
A. RemoveMemoryPressure()
B. ReRegisterForFinalize()
C. WaitForFullGCComplete()
D. KeepAlive()
Answer: D
Q114. HOTSPOT - (Topic 1)
You are implementing a library method that accepts a character parameter and returns a string.
If the lookup succeeds, the method must return the corresponding string value. If the lookup fails, the method must return the value "invalid choice."
You need to implement the lookup algorithm.
How should you complete the relevant code? (To answer, select the correct keyword in each drop-down list in the answer area.)
Answer:
Q115. - (Topic 2)
You are developing an application for a bank. The application includes a method named ProcessLoan that processes loan applications. The ProcessLoan() method uses a method named CalculateInterest. The application includes the following code:
You need to declare a delegate to support the ProcessLoan() method. Which code segment should you use?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
Q116. - (Topic 2)
You are creating an application that processes a list of numbers.
The application must define a method that queries the list and displays a subset of the
numbers to the user. The method must not update the list.
You need to create an extendable query by using LINQ.
What should you do?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
Q117. - (Topic 1)
You are developing an application that will transmit large amounts of data between a client computer and a server. You need to ensure the validity of the data by using a cryptographic hashing algorithm. Which algorithm should you use?
A. RSA
B. Aes
C. HMACSHA256
D. DES
Answer: C
Q118. - (Topic 2)
You have the following code (line numbers are included for reference only):
You need to ensure that if an exception occurs, the exception will be logged. Which code should you insert at line 28?
A. Option A
B. Option B
C. Option C
D. Option D
Answer: C
Explanation: * XmlWriterTraceListener
Directs tracing or debugging output as XML-encoded data to a TextWriter or to a Stream,
such as a FileStream.
* TraceListener.TraceEvent Method (TraceEventCache, String, TraceEventType, Int32) Writes trace and event information to the listener specific output.
Syntax:
[ComVisibleAttribute(false)]
public virtual void TraceEvent(
TraceEventCache eventCache,
string source,
TraceEventType eventType,
int id
)
Q119. DRAG DROP - (Topic 1)
You are testing an application. The application includes methods named CalculateInterest and LogLine. The CalculateInterest() method calculates loan interest. The LogLine() method sends diagnostic messages to a console window.
You have the following requirements:
. The CalculateInterest() method must run for all build configurations.
. The LogLine() method must be called only for debug builds.
You need to ensure that the methods run correctly.
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:
