Palo Alto Networks Cybersecurity Entry-Level Technician (PCCET) — Question 36

What is the proper subnet mask for the network 192.168.55.0/27?

Answer options

• A. 255.255.255.192
• B. 255.255.255.248
• C. 255.255.255.224
• D. 255.255.255.0

Correct answer: C

Explanation

The correct subnet mask for a /27 network is 255.255.255.224, which allows for 32 IP addresses, 30 of which can be assigned to hosts. The other options either provide too few addresses or are for different subnet sizes, making them incorrect for this specific network configuration.
