The SecOps Group Certified Network Security Practitioner Sample Questions (Q31-Q36):

NEW QUESTION # 31
What is the response from a closed TCP port which is behind a firewall?

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

Answer: D

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 # 32
Which of the following is a valid DNS record type?

  • A. NAPTR record
  • B. TXT record
  • C. All of the above
  • D. SRV record

Answer: C

Explanation:
DNS (Domain Name System) records define how domain names are mapped to various types of data, each serving a specific purpose in network operations. The question asks for valid DNS record types, and all listed options are recognized.
Why D is correct:
A . NAPTR record: The Naming Authority Pointer (NAPTR) record is used for service discovery and mapping domain names to services, protocols, and ports (e.g., in SIP or ENUM systems).
B . SRV record: The Service (SRV) record specifies the hostname and port for specific services (e.g., LDAP, XMPP), aiding in service location.
C . TXT record: The Text (TXT) record stores arbitrary text data, often for SPF, DKIM, or domain verification.
All are valid DNS record types per RFC standards and CNSP documentation, making "All of the above" the correct answer.
Why other options are incomplete: A, B, or C alone exclude other valid types listed, so D is the most comprehensive response.


NEW QUESTION # 33
What is the response from an open TCP port which is not behind a firewall?

  • A. A SYN packet
  • B. A FIN and an ACK packet
  • C. A SYN and an ACK packet
  • D. A RST and an ACK packet

Answer: C

Explanation:
TCP's three-way handshake, per RFC 793, establishes a connection:
Client → Server: SYN (Synchronize) packet (e.g., port 80).
Server → Client: SYN-ACK (Synchronize-Acknowledge) packet if the port is open and listening.
Client → Server: ACK (Acknowledge) completes the connection.
Scenario: An open TCP port (e.g., 80 for HTTP) with no firewall. When a client sends a SYN to an open port (e.g., via telnet 192.168.1.1 80), the server responds with a SYN-ACK packet, indicating willingness to connect. No firewall means no filtering alters this standard response.
Packet Details:
SYN-ACK: Sets SYN and ACK flags in the TCP header, with a sequence number and acknowledgment number.
Example: Client SYN (Seq=100), Server SYN-ACK (Seq=200, Ack=101).
Security Implications: Open ports responding with SYN-ACK are easily detected (e.g., Nmap "open" state), inviting exploits if unneeded (e.g., Telnet on 23). CNSP likely stresses port minimization and monitoring.
Why other options are incorrect:
A . A FIN and an ACK packet: FIN-ACK closes an established connection, not a response to a new SYN.
B . A SYN packet: SYN initiates a connection from the client, not a server response.
D . A RST and an ACK packet: RST-ACK rejects a connection (e.g., closed port), not an open one.
Real-World Context: SYN-ACK from SSH (22/TCP) confirms a server's presence during reconnaissance.


NEW QUESTION # 34
Which of the following commands will work on a Microsoft operating system to add a new domain admin user?

  • A. net group "Administrator" John /add
  • B. net user John /add /domain /admin
  • C. net user John "Domain Admins" /add /domain
  • D. net group "Domain Admins" John /add /domain

Answer: D

Explanation:
Adding a user to a domain group like "Domain Admins" requires the correct command and scope (domain vs. local).
Why A is correct: net group "Domain Admins" John /add /domain adds user John to the domain-level "Domain Admins" group, per CNSP's domain privilege management.
Why other options are incorrect:
B: net user creates users, not group memberships; syntax is wrong.
C: /admin is invalid; correct group specification is missing.
D: Targets local "Administrator" group, not domain "Domain Admins".


NEW QUESTION # 35
What is the response from a closed UDP port which is not behind a firewall?

  • A. None of the above
  • B. A RST packet
  • C. No response
  • D. ICMP message showing Destination Unreachable

Answer: D

Explanation:
UDP is a connectionless protocol, and its behavior when a packet reaches a port depends on whether the port is open or closed. Without a firewall altering the response, the standard protocol applies.
Why A is correct: When a UDP packet is sent to a closed port, the host typically responds with an ICMP Type 3 (Destination Unreachable), Code 3 (Port Unreachable) message, indicating no service is listening. CNSP notes this as a key indicator in port scanning.
Why other options are incorrect:
B: RST packets are TCP-specific, not used in UDP.
C: No response occurs for open UDP ports unless an application replies, not closed ports.
D: A is correct, so "none of the above" is invalid.
