You work as the developer in an IT company. Recently your company has a big customer. The customer runs a large supermarket chain. You're appointed to provide technical support for the customer. Now you are creating a class which contains a method named GetCurrentRate. The class performs complex financial calculations. The GetCurrentRate method retrieves the current interest rate and a variable named currRate that stores the current interest rate. You have to write a code segment. When an instance of the class is deserialized, the code segment updates the currRate variable with the current interest rate. In the options below, which code segment should you use?

• A. [OnDeserializing]internal void UpdateValue(SerializationInfo info) { info.AddValue("currentRate", GetCurrentRate());}
• B. [OnSerializing]internal void UpdateValue(SerializationInfo info) { info.AddValue("currentRate", GetCurrentRate());}
• C. [OnSerializing]internal void UpdateValue (StreamingContext context) { currRate = GetCurrentRate();}
• D. [OnDeserialized]internal void UpdateValue(StreamingContext context) { currRate = GetCurrentRate();}

You work as the developer in an IT company. Recently your company has a big customer. The customer runs a large supermarket chain. You're appointed to provide technical support for the customer. The customer needs to compress an array of bytes. So you are writing a method to compress bytes. The bytes are passed to the method in a parameter named document. The contents of the incoming parameter have to be compressed. Which code segment should you use?

• A. MemoryStream stream = new MemoryStream(document);GZipStream zipStream = new GZipStream(stream, CompressionMode.Compress);zipStream.Write(document, 0, document.Length);zipStream.Close();return stream.ToArray();
• B. MemoryStream inStream = new MemoryStream(document);GZipStream zipStream = new GZipStream(inStream, CompressionMode.Compress); MemoryStream outStream = new MemoryStream();int b;while ((b = zipStream.ReadByte()) != -1) { outStream.WriteByte((byte)b);} return outStream.ToArray();
• C. MemoryStream inStream = new MemoryStream(document);GZipStream zipStream = new GZipStream(inStream, CompressionMode.Compress); byte[] result = new byte[document.Length];zipStream.Write(result, 0, result.Length); return result;
• D. MemoryStream outStream = new MemoryStream();GZipStream zipStream = new GZipStream(outStream, CompressionMode.Compress);zipStream.Write(document, 0, document.Length);zipStream.Close();return outStream.ToArray();

• B. <asp:CatalogZone ID="CatalogZone1" Runat="server"> <ZoneTemplate> <asp:PageCatalogPart Runat="server" ID="PageCatalogPart1" /> </ZoneTemplate></asp:CatalogZone>
• C. <asp:ProxyWebPartManager ID="ProxyWebPartmanager1" Runat="server" />
• D. <asp:WebPartZone ID="WebPartZone1" Runat="server"> <ZoneTemplate> </ZoneTemplate></asp:WebPartZone>

You work as the developer in an IT company. Recently your company has a big customer. The customer runs a large supermarket chain. You're appointed to provide technical support for the customer.

• A. You should add a method to the code-behind file named isColor. Ensure that it uses the MobileCapabilities class and returns a string indicating the URL of the image to display.
• B. You should add the following code segment between your image control definition tags. <DeviceSpecific> <Choice Filter="isColor" ImageURL="logo-color.gif" /></DeviceSpecific>
• C. You should add a method to the code-behind file named isColor. Ensure that it returns a Boolean value and takes an instance of the MobileCapabilities class and a string.
• D. You should add the following node to the deviceFilters element within the Web.config file. <filter name="isColor" compare="IsColor" argument="true" />
