70-536 MCTS .NET Foundations #25

Hey Now,

Please feel free to check out my MCTS 70-536 reference page on Chris Catto.com. It’s a page with a summary of all of my posts.
As I study for this test I thought this would be good to post on to learn the content & others would be able to view & comment on it.

This content below is from some practice questions from the internet & not sure the answers are correct. There were over 200 questions & some duplicates, I hope to study all of them. I’ve also added some of my notes to these so any line starting with K8 (my nickname, first syllable of Catt o ) are my comments.

Thx,

Catto

Q#80 – Q#99

Question: 80

You work as a developer at Company.com. You are developing an application to create a new file on the local file system.

You need to define specific security settings for the file. You must deny the file inheritance of any default security settings.
What should you do?

Answer: ?

K8 – not so good of a question. No answers or answer.

Question: 81

You are creating a class to compare a specially-formatted string. The default collation comparisons do not apply. You need to implement the IComparable(Of String) interface. Which code segment should you use?

A. Public Class Person

Implements IComparable(Of String)Public Function CompareTo(ByVal other As String)

As _Integer Implements IComparable(Of String).CompareTo...End FunctionEnd Class

B. Public Class Person

Implements IComparable(Of String)Public Function CompareTo(ByVal other As Object)

As _Integer Implements IComparable(Of String).CompareTo...End FunctionEnd Class

C. Public Class Person

Implements IComparable(Of String)Public Function CompareTo(ByVal other As String)

_As Boolean Implements IComparable(Of String).CompareTo...End FunctionEnd Class

D. Public Class Person

Implements IComparable(Of String)Public Function CompareTo(ByVal other As Object)

_As Boolean Implements IComparable(Of String).CompareTo...End FunctionEnd Class

Answer: A

K8 – String & IComparable as int

Question: 82

You work as a developer at Company.com. You create a service application that monitors free space on a hard disk drive. You must ensure that the service application runs in the background and monitors the free space every minute.

What should you do?

Answer:

K8 – Another not so good question no answers

Question: 83

You are creating a class that performs complex financial calculations. The class contains a method named GetCurrentRate that retrieves the current interest rate and a variable named currRate that stores the current interest rate.
You write serialized representations of the class. You need to write a code segment that updates the currRate variable with the current interest rate when an instance of the class is deserialized. Which code segment should you use?

A. [OnSerializing]internal void UpdateValue (StreamingContext context) {

currRate = GetCurrentRate();}

B. [OnSerializing]internal void UpdateValue(SerializationInfo info) {

info.AddValue(“currentRate”, GetCurrentRate());}

C. [OnDeserializing]internal void UpdateValue(SerializationInfo info) {

info.AddValue(“currentRate”, GetCurrentRate());}

D. [OnDeserialized]internal void UpdateValue(StreamingContext context) {

currRate = GetCurrentRate();}

Answer: D

Answer: C

K8 – c is the only Sub not a function isn’t that something?

Question: 85

You create a class library that is used by applications in three departments of your company. The library contains a Department class with the following definition. public

<manager>Company</manager>

</Department>

You need to write a code segment that creates a Department object instance by using the field values retrieved from the application configuration file. Which code segment should you use?

protected :
override void DeserializeElement(XmlReader^ reader,
bool^ serializeCollectionKey) {
Department^ dept = gcnew Department();
dept->name = ConfigurationManager::AppSettings[“name”];
dept->manager = ConfigurationManager::AppSettings[“manager”];
return dept; }};

B. public ref class deptElement : public ConfigurationElement {
protected :
override void DeserializeElement(XmlReader^ reader,
bool^ serializeCollectionKey) {
Department^ dept = gcnew Department();
dept->name = reader->GetAttribute(“name”);
dept->manager = reader->GetAttribute(“manager”); }};

C. public ref class deptHandler :
public IConfigurationSectionHandler {
public :
Object^ Create(Object^ parent, Object^ configContext,
System.Xml.XmlNode section) {
Department^ dept = gcnew Department();
dept->name = section->SelectSingleNode(“name”)->InnerText;
dept->manager = section->SelectSinglenode(“manager”)->InnerText;
return dept; }};
D. public ref class deptHandler : public IConfigurationSectionHandler {

public :
Object^ Create(Object^ parent, Object^ configContext,
System.Xml.XmlNode^ section) {
Department^ dept = gcnew Department();
dept->name = section->Attributes[“name”].Value;

Question: 74

You are creating a new security policy for an application domain. You write the following lines of code.
Dim objPolicy As PolicyLevel = PolicyLevel.CreateAppDomainLevelDim

noTrustStatement As New PolicyStatement( _

objPolicy.GetNamedPermissionSet("Nothing"))

Dim fullTrustStatement As New PolicyStatement( _

Dim objGroup2 As CodeGroup = New UnionCodeGroup( _

New ZoneMembershipCondition(SecurityZone.Trusted), _
fullTrustStatement)

C. Dim objGroup As CodeGroup = New UnionCodeGroup( _
New ZoneMembershipCondition(SecurityZone.Trusted), _

Employees;17. };

You create an instance of the Group class. You populate the fields of the instance. When you attempt to serialize the instance by using the Serialize method of the XmlSerializer class, you receive InvalidOperationException. You also receive the following error message: "There was an error generating the XML document." You need to modify the code segment so that you can successfully serialize instances of the Group class by using the XmlSerializer class. You also need to ensure that the XML output contains an element for all public fields in the class hierarchy. What should you do?
