To answer this question, you need to understand the concept of FTP (File Transfer Protocol). Let's go through each option to understand why it is correct or incorrect:

Option A) File Transmission Protocol - This option is incorrect because the correct term is "File Transfer Protocol" (FTP), not "File Transmission Protocol".

Option B) File Transfer Protocol - This option is correct. FTP is a standard network protocol used to transfer files between a client and a server on a computer network.

Option C) Transmission control Protocol - This option is incorrect. The Transmission Control Protocol (TCP) is a different protocol that provides reliable, ordered, and error-checked delivery of a stream of bytes between applications running on hosts on a network.

Option D) Data Transmission protocol - This option is incorrect. There is no specific protocol called "Data Transmission Protocol". FTP is the correct term for the protocol used for file transfer.

The correct answer is B) File Transfer Protocol. This option is correct because FTP is a standard network protocol used for transferring files between a client and a server.

To answer this question, we need to understand the different attributes of a file that can be changed while transmitting to a remote host.

Option A) LRECL - This option is incorrect because the LRECL (Logical Record Length) is a fixed attribute of a file that specifies the length of each record in the file. It cannot be changed while transmitting the file to a remote host.

Option B) RECFM - This option is incorrect because the RECFM (Record Format) is another fixed attribute of a file that specifies the format of each record in the file. It also cannot be changed while transmitting the file to a remote host.

Option C) None of the attributes can be changed - This option is incorrect because there are certain attributes of a file that can be changed while transmitting to a remote host.

Option D) All the attributes can be changed - This option is correct because there are certain attributes of a file that can be changed while transmitting to a remote host. These attributes include the file permissions, file ownership, file timestamps, etc. These attributes can be modified during the transmission process.

Therefore, the correct answer is option D) All the attributes can be changed.

To copy one file from the remote machine to the local machine, the correct parameter is "GET".

Let's go through each option to understand why it is correct or incorrect:

Option A) OPEN - The "OPEN" parameter is not used for copying files from a remote machine to the local machine. It is used to establish a connection to a remote machine or open a file.

Option B) RMDIR - The "RMDIR" parameter is used to remove a directory on the remote machine. It is not used for copying files.

Option C) OUT - The "OUT" parameter is used to redirect the output of a command to a file or a device. It is not used for copying files from a remote machine to the local machine.

Option D) GET - The "GET" parameter is used to retrieve a file from a remote machine and copy it to the local machine. This is the correct parameter for copying files from the remote machine to the local machine.

The correct answer is option D. This option is correct because the "GET" parameter is used to copy one file from the remote machine to the local machine.

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Avoid having to bind a large number of DBRM members into a plan - This option is incorrect because using a package does not necessarily avoid the need to bind a large number of DBRM (Database Request Module) members into a plan. A package is a container that holds the compiled SQL statements and associated access paths, but it still requires binding.

Option B) Minimize fallback complexities if changes result in an error - This option is incorrect because using a package does not specifically minimize fallback complexities. Fallback complexities are related to the process of reverting to a previous version of the program or application if changes result in an error, and using a package does not directly address this.

Option C) Avoid cost of a large bind - This option is incorrect because using a package does not necessarily avoid the cost of binding. Binding is still required for a package in order to compile the SQL statements and create the access paths.

Option D) Time consumption is reduced - This option is correct because using a package can reduce the time consumption in certain scenarios. When a package is bound, the SQL statements and access paths are already compiled and stored, which can save time during execution as the statements do not need to be recompiled each time they are executed.

The correct answer is D) Time consumption is reduced.

To answer this question, let's go through each option to understand why it is correct or incorrect:

Option A) Caused by invalid Data in a Numeric field - This option is incorrect. The S0C4 error is not caused by invalid data in a numeric field. Instead, it is related to a protection exception.

Option B) Protection Exception - This option is correct. The S0C4 error is a protection exception error. It occurs when a program attempts to access storage that it does not have permission to access. This can happen due to various reasons such as accessing an uninitialized variable or accessing memory outside the program's allocated storage.

Option C) Timeout - This option is incorrect. The S0C4 error is not related to a timeout. It is specifically related to a protection exception.

Option D) Data protection Exception - This option is incorrect. The S0C4 error is related to a protection exception, but it is not specifically called a "Data Protection Exception."

The correct answer is B) Protection Exception. This option is correct because the S0C4 error is a protection exception error.
