What does the following display filter do in Wireshark?

ip.src == 192.168.1.1

• Displays only TCP packets where the SYN flag is set and the source IP is 192.168.1.1

• Displays all packets sent from and to 192.168.1.1

• Displays packets with the ACK flag set and originating from 192.168.1.1

• Filters all TCP packets regardless of their source

What is the main difference between a capture filter and a display filter in Wireshark?

• Capture filters are applied to live traffic, while display filters refine what is shown after capture.

• Capture filters can use logical operators, while display filters cannot.

• Display filters are permanent, while capture filters are temporary.

• Capture filters only work for specific protocols, while display filters work for all protocols.

In the following Python code, what will be the output?

def mystery(x):

return x * 2 if x % 2 == 0 else x + 1

• 6 and 8

• 4 and 5

• 4 and 8

• 6 and 5

What is the purpose of the following line in Python, commonly used in file handling?

with open("data.txt", "r") as file:

content = file.read()

• Opens the file and reads its content, automatically closing the file afterward.

• Opens the file for writing only.

• Opens the file without closing it, ensuring faster execution.

• Deletes the file after reading its content.

What happens if the Caesar cipher is implemented with a key equal to 26?

• The plaintext is encrypted into a completely different ciphertext.

• The ciphertext is identical to the plaintext.

• It causes an error because the key must be between 1 and 25.

• It results in a reversed version of the plaintext.
