Answer:
B. Role-based access controls
Explanation:
Roll-based access control is a way to control access to the network and to data which depends on the position of employees in a department. This way the permission to access information are granted according to roles that are assigned to employees. This type of access control allows access privileges to employees only to the folders and data files which they need in order to perform their tasks and it does not allow them to access the data or information which is not relevant to them. This helps the department to secure the sensitive information and data files and reduces the risk of data breaches.
2 + 3 + 4 = 9 so the value of result is also 9
Answer
First part:
The transmitted 8-bit sequence for ASCII character '&' with odd parity will be 00100110. Here leftmost bit is odd parity bit.
Second part:
The invalid bit sequence are option a. 01001000 and d. 11100111
Explanation:
Explanation for first part:
In odd parity, check bit of either 0 or 1 is added to the binary number as leftmost bit for making the number of 1s in binary number odd.
If there are even number of 1s present in the original number then 1 is added as leftmost bit to make total number of 1s odd.
If there are odd number of 1s present in the original number then 0 is added as leftmost bit to keep the total number of 1s odd.
Explanation for second part:
A valid odd parity bit sequence will always have odd number of 1s.
Since in option a and d, total number of 1s are 2 and 6 i.e. even number. Therefore they are invalid odd parity check bit sequences.
And since in option b and c, total number of 1s are 5 and 7 i.e. odd numbers respectively. Therefore they are valid odd parity check bit sequences.
