Q:

Describe the functions of DNS and DHCP in the network?

Answer

Dynamic Host Configuration protocol (DHCP) provides network configuration information (including IP address) to hosts, eliminating the need to perform the configurations manually.


Domain Name Service  (DNS)resolves hostnames - both internet names such as www.routersim.com and device names such as workstation 2 to IP addresses, eliminating the need to know the IP address of a device for connection purposes.

Q:

You are creating an ASP.NET page for a travel service. The page contains a CheckBoxList control that contains travel destinations. Customer can select favorite destinations to receive weekly e-mail updates of travel packages.

 

The CheckBoxList control is bound to a database table of possible destinations. Each destination is ranked according to its popularity. You modify the page to sort the destination list by rank, from the most popular to the least popular. The list has three columns.

 

You want the most popular destination to be on the top row of the check box list at run time. Which property setting should you use for the CheckBoxList control?

A) Set the RepeatDirection property to Vertical. B) Set the RepeatDirection property to Horizontal.
C) Set the RepeatLayout property to Flow. D) Set the RepeatLayout property to Table.
 
Answer & Explanation Answer: B) Set the RepeatDirection property to Horizontal.

Explanation:

The DataList.RepeatDirection property is used to get or select whether the DataList control displays vertically or horizontally. If this property is set to RepeatDirection.Horizontal, the items in the list are displayed in rows loaded from left to right, then top to bottom, until all items are rendered.

 

Incorrect Answers:

A: If the DataList.RepeatDirection property is set to RepeatDirection.Vertical, the items in the list are displayed in columns loaded from top to bottom, then left to right, until all items are rendered.


C, D:DataList.RepeatLayout Property gets or sets whether the control is displayed in a table or flow layout. It does not affect the order in which the items are displayed.

Q:

You use Visual Studio .NET to create an assembly, called XYZAssembly, that will be used by other applications, including a standard COM client application.


You must deploy your assembly on the COM application to a client computer. You must ensure that the COM application can instantiate components within the assembly as COM components.

What should you do?

A) Create a strong name of the assembly by using the Strong Name tool (Sn.exe). B) Generate a type library for the assembly by using the Type Library Importer (Tlbimp.exe). Register the file on the client computer.
C) Generate a registry file for the assembly by using the Assembly Registration tool (Regasm.exe) Register the file on the client computer. D) Deploy the assembly to the global assembly cache on the client computer. Add a reference to the assembly in the COM client application.
 
Answer & Explanation Answer: C) Generate a registry file for the assembly by using the Assembly Registration tool (Regasm.exe) Register the file on the client computer.

Explanation:

The Assembly Registration tool reads the metadata within an assembly and adds the necessary entries to the registry, which allows COM clients to create .NET Framework classes transparently. Once a class is registered, any COM client can use it as though the class were a COM class..

 

Incorrect Answers:

Option A:
The Strong Name tool helps sign assemblies with strong names.


Option B:
The Type Library Importer, tlbimp.exe, converts the type definitions found within a COM type library into equivalent definitions in a common language runtime assembly. It would not be useful in this scenario however.


Option D:
This would not allow the COM application to use the class.
