The SecOps Group Certified Network Security Practitioner Sample Questions (Q33-Q38):

NEW QUESTION # 33
What kind of files are "Dotfiles" in a Linux-based architecture?

• A. Hidden files
• B. System files
• C. Library files
• D. Driver files

Answer: A

Explanation:
In Linux, file visibility is determined by naming conventions, impacting how files are listed or accessed in the file system.
Why D is correct: "Dotfiles" are files or directories with names starting with a dot (e.g., .bashrc), making them hidden by default in directory listings (e.g., ls requires -a to show them). They are commonly used for user configuration, as per CNSP's Linux security overview.
Why other options are incorrect:
A: Library files (e.g., in /lib) aren't inherently hidden.
B: Driver files (e.g., kernel modules in /lib/modules) aren't dotfiles by convention.
C: System files may or may not be hidden; "dotfiles" specifically denotes hidden status.

NEW QUESTION # 34
What is the response from a closed TCP port which is behind a firewall?

• A. RST and an ACK packet
• B. A SYN and an ACK packet
• C. No response
• D. A FIN and an ACK packet

Answer: C

Explanation:
TCP (Transmission Control Protocol) uses a three-way handshake (SYN, SYN-ACK, ACK) to establish connections, as per RFC 793. When a client sends a SYN packet to a port:
Open Port: The server responds with SYN-ACK.
Closed Port (no firewall): The server sends an RST (Reset) packet, often with ACK, to terminate the attempt immediately.
However, when a firewall is present, its configuration dictates the response. Modern firewalls typically operate in stealth mode, using a "drop" rule for closed ports rather than a "reject" rule:
Drop: Silently discards the packet without replying, resulting in no response. The client experiences a timeout (e.g., 30 seconds), as no feedback is provided.
Reject: Sends an RST or ICMP "Port Unreachable," but this is less common for security reasons, as it confirms the firewall's presence.
For a closed TCP port behind a firewall, "no response" (drop) is the standard behavior in secure configurations, minimizing information leakage to attackers. This aligns with CNSP's focus on firewall best practices to obscure network topology during port scanning (e.g., with Nmap).
Why other options are incorrect:
A . A FIN and an ACK packet: FIN-ACK is used to close an established TCP connection gracefully (e.g., after data transfer), not to respond to an initial SYN on a closed port.
B . RST and an ACK packet: RST-ACK is the host's response to a closed port without a firewall. A firewall's drop rule overrides this by silently discarding the packet.
C . A SYN and an ACK packet: SYN-ACK indicates an open port accepting a connection, the opposite of a closed port scenario.
Real-World Context: Tools like Nmap interpret "no response" as "filtered" (firewall likely present) vs. "closed" (RST received), aiding in firewall detection.

NEW QUESTION # 35
What will be the subnet mask for 192.168.0.1/18?

• A. 255.225.225.0
• B. 255.255.255.0
• C. 255.225.192.0
• D. 255.255.192.0

Answer: D

Explanation:
An IP address with a /18 prefix (CIDR notation) indicates 18 network bits in the subnet mask, leaving 14 host bits (32 total bits - 18). For IPv4 (e.g., 192.168.0.1):
Binary Mask: First 18 bits are 1s, rest 0s.
1st octet: 11111111 (255)
2nd octet: 11111111 (255)
3rd octet: 11000000 (192)
4th octet: 00000000 (0)
Decimal: 255.255.192.0
Calculation:
Bits: /18 = 2
