How many protocols are used in the application layer?

Some small cubes of same height 7 cm but variable length and width are put inside a large cuboid of height 21 cm. Length and width of cuboid is 32 cm and 24 cm, respectively. Small cubes are put such that cubes at the bottom most layer is of similar base area; second layer contains all the cubes of similar base area and third layer have all the cubes of similar base area. Which of the following statement(s) given below is / are TRUE? A: If side of each small cubes at bottom most layer is 8 cm, then maximum number of small cubes that can be put at bottom most layer is 12. B: If maximum of 48 cubes can be put at second layer, then side of each cube at second layer is 6 cm. C: If side of each small cubes at third layer is 1.6 cm, then maximum number of small cubes that can be put at third layer is 300.

Consider the following three statements about link state and distance vector routing protocols, for a large network with 500 network nodes and 4000 links. [S1] The computational overhead in link state protocols is higher than in distance vector protocols. [S2] A distance vector protocol (with split horizon) avoids persistent routing loops, but not a link state protocol. [S3] After a topology change, a link state protocol will converge faster than a distance vector protocol. Which one of the following is correct about S1, S2, and S3?

A

S1, S2, and S3 are all true.

B

S1, S2, and S3 are all false

C

S1 and S2 are true, but S3 is false.

D

S1 and S3 are true, but S2 is false

You are the administrator of a SQL Server 2000 computer. The server contains a database named FinanceData that is used by a client/server application. Each employee has a SQL Server login that the application uses to access the server.Your company hires a new employee named Andrew. You create a SQL Server login named Andrew. You also create a database user named Andrew in the database and grant the database user full permissions in the database.Whenever Andrew runs the client/server application, he receives the following error message: "Invalid object name." Andrew also reports that he cannot access the database by using the application.You need to ensure that Andrew can use the application. Which Transact-SQL statement should you execute?

A

EXEC sp_defaultdb 'Andrew','FinanceData'

B

GRANT ALL ON FinanceData TO Andrew

C

EXEC sp_addlogin 'Andrew'

D

EXEC sp_grantdbaccess 'FinanceData','Andrew'GOsp_addrolemember 'db_datareader','Andrew'

You install and run a third-party 32-bit application named Application on your Windows 2000 Server computer. After several days, the application stops responding. You open Task Manager and find that the CPU usage is at 100 percent. The normal range of CPU usage on the server is from 20 percent to 30 percent You end the application. However, you see that the CPU on the server is still at 100 percent. Task Manager shows no other applications running. You then examine the Processes page in Task Manager and confirm that the Application.exe process is no longer running. You want to return the CPU usage to its normal range. What should you do?

A

Use Computer Management to stop and restart the Server service
