NO.1 You are creating an application that manages information about zoo animals. The application

includes a

class named Animal and a method named Save. The Save() method must be strongly typed. It must

allow

only types inherited from the Animal class that uses a constructor that accepts no parameters. You

need

to implement the Save() method. Which code segment should you use?

A. public static void Save<T>(T target) where T : Animal {...}

B. public static void Save<T>(T target) where T : new(), Animal{...}

C. public static void Save(Animal target) {...}

D. public static void Save<T>(T target) where T : Animal, new() {...}

Answer: D

 

NO.2 You need to recommend a disk monitoring solution that meets the business requirements.

What should

you include in the recommendation?

A. a SQL Server Agent alert

B. a maintenance plan

C. a dynamic management view

D. an audit

Answer: C

 

NO.3 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. HMACSHA256

B. HMACSHA512

C. Aes

D. RSA

E. Rfc2898DeriveBytes

F. ECDsa

G. RNGCryptoServiceProvider

H. DES

Answer: AB

 

NO.4 You are debugging an application that calculates loan interest. The application includes the

following

code. (Line numbers are included for reference only.) 01 private static decimal

CalculateInterest(decimal

loanAmount, int loanTerm, decimal loanRate)02 {03

04

decimal interestAmount = loanAmount * loanRate * loanTerm;05

06

return interestAmount;07 } You have the following requirements:

The debugger must break execution within the CalculateInterest() method when the loanAmount

variable

is less than or equal to zero.

The release version of the code must not be impacted by any changes. You need to meet the

requirements. What should you do?

A. Insert the following code segment at line 05: Trace.Write(loanAmount > 0);

B. Insert the following code segment at line 03: Trace.Assert(loanAmount > 0);

C. Insert the following code segment at line 05: Debug.Write(loanAmount > 0);

D. Insert the following code segment at line 03: Debug.Assert(loanAmount > 0);

Answer: D

 

NO.5 An application will upload data by using HTML form-based encoding. The application uses a

method

named SendMessage. The SendMessage() method includes the following code. (Line numbers are

included for reference only.) 01 public Task<byte[]> SendMessage(string url, int intA, int intB)02 {03

var client = new WebClient();04 05 } The receiving URL accepts parameters as form-encoded values.

You

need to send the values intA and intB as form-encoded values named a and b, respectively. Which

code

segment should you insert at line 04?

A. var data = string.Format("a={0}&b={1}", intA, intB);return client.UploadStringTaskAsync(new

Uri(url),

data);

B. var data = string.Format("a={0}&b={1}", intA, intB);return client.UploadFileTaskAsync(new

Uri(url),

data);

C. var data = string.Format("a={0}&b={1}", intA, intB);return client.UploadDataTaskAsync(new

Uri(url),

Encoding.UTF8.GetBytes(data));

D. var nvc = new NameValueCollection() { { "a", intA.ToString() }, { "b", intB.ToString() } };return

client.UploadValuesTaskAsync(new Uri(url), nvc);

Answer: D
