a. Press the F3 (Exit) key and enter "logoff" on the Primary Option Menu.

b. Enter the letter "X" on the command line of the ISPF Primary Option Menu or press the F12 (Cancel) key.

Explanation:

ISPF (Interactive System Productivity Facility) is a software application that provides a user-friendly interface for performing various tasks on a mainframe computer. To end an ISPF session, you can either press the F3 (Exit) key and enter "logoff" on the Primary Option Menu, or enter the letter "X" on the command line of the ISPF Primary Option Menu or press the F12 (Cancel) key. Option c is incorrect because entering the word "end" on the command line of the ISPF Primary Option Menu will not end the ISPF session. Option d is incorrect because pressing the F12 (Cancel) key alone will not end the ISPF session; you must also enter "logoff" on the Primary Option Menu.

When an alarm is set off without any genuine security danger or circumstance that would warrant the warning, it is known as an intrusion detection systems false positive alert.

False positives in intrusion detection systems (IDS) are a typical occurrence and can be brought on by a number of things, including misconfiguration, noisy data, or out-of-date signatures. An IDS false positive alert is one that is generated when there is no actual security risk or condition that would justify the warning. False positives may be inconvenient and time-consuming to investigate, but they are typically viewed as preferable than failing to identify a real positive, which would permit a security breach to take place unnoticed. IDS administrators should routinely evaluate and improve their systems to reduce the frequency of false positives.

When we transmit data as a block of n rows of k bits per row and add parity bits to each row and each column, the given scheme detects all single errors. However, it doesn't detect all double errors and triple errors.

A block parity check is an error detection code that is designed to verify data transmission accuracy by introducing parity bits into data blocks. By comparing the parity of the received data with the transmitted data, an error in transmission can be detected.

For simplicity, let's assume that error occurs only in the data part and not in the parity part, and the block size is n rows of k bits per row.A single error will always be detected because it changes the parity of the row or column.

When two errors occur in a row or column, it will not be detected, but a double error occurring in two different rows or columns will be detected because it affects the parity of two rows or columns. However, a triple error occurring in three different rows or columns will not be detected.
