which two protocols operate at the transport layer of the tcp/ip model? (choose two.)

If the addressing mode for the operating instruction "lda 800" is immediate, then the value at memory address 800 would be loaded directly into the accumulator (AC) register of the computer's central processing unit (CPU).

Immediate addressing mode means that the operand (the value to be loaded into the AC in this case) is specified directly in the instruction itself, rather than being stored in memory and referenced indirectly through an address. So, in this case, the instruction is telling the CPU to load the value at memory address 800 directly into the AC. It's worth noting that the size of the operand in immediate addressing mode is usually limited to the size of the instruction itself. So, if the instruction is 16 bits, for example, then the operand would typically be limited to 16 bits as well. In summary, if the instruction "lda 800" is using immediate addressing mode, then the value at memory address 800 would be directly loaded into the accumulator register of the CPU.

To correctly implement the `computepay` method in the `Consultant` class, you would need to redefine it to incorporate the bonus and tax calculation. Here's a possible implementation in 110 words:

```python

class Consultant(Employee):

   def computepay(self):

       tax_rate = 0.1  # Assuming a 10% tax rate

       salary = super().computepay()

       tax_withheld = salary * tax_rate

       net_salary = salary - tax_withheld

       bonus = 1000  # Assuming a fixed bonus amount of $1000

       total_pay = net_salary + bonus

       return total_pay

```

In this implementation, the method `computepay` in the `Consultant` class first calls the parent class's `computepay` method using `super().computepay()` to calculate the initial salary. Then, it calculates the tax withheld based on a predefined tax rate.

The net salary is obtained by subtracting the tax withheld from the initial salary. Finally, a bonus amount is added to the net salary to obtain the total pay, which is then returned.

In a basic VLAN hopping attack, attackers typically take advantage of the switch feature called Dynamic Trunking Protocol (DTP).

This feature allows for the insertion of one VLAN tag inside another VLAN tag, essentially creating a nested VLAN. Attackers can exploit this by sending packets with two VLAN tags, the first being a legitimate VLAN tag to pass through the switch, and the second being a rogue VLAN tag that the attacker has created.

The switch, upon receiving the packet, will read the first VLAN tag and forward it to the appropriate VLAN. However, it will also read the second VLAN tag and assume that it is the legitimate VLAN tag, allowing the attacker to bypass security measures and gain access to the rogue VLAN. By doing this, attackers can potentially gain access to sensitive information, intercept traffic, and carry out other malicious activities.
