Hope this Helps!!!
Answer:
a. make multiple fixes.
Explanation:
When we are troubleshooting firewalls we should not make multiple fixes after attempting a fix because it will not be beneficial for the security purpose.
We can repeat the failure after attempting the fix because we can fix it but a person with right mind won't be doing that.
We can test after each attempt that it is working properly.
We can also reverse or undo the solution failures after making a fix.

Answer:
C. 7200 bps.
Explanation:
In networking, transmission lines or connectors and ports operates at a specific speed based on the port type and the cable or medium of transmission.
Baud rate is a concept in digital information technology that defines the rate of symbol per channel during transmission. The bit or data rate is the number of bits transfered in a link per second.
The relationship between baud rate and bit rate is;
Bit rate = baud rate x number of symbol bit level
To get the bit rate of a 2400 baud signal with symbol level = 8 = 2^3
Bit rate = 2400 x 3. = 7200 bps.
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.
