The SecOps Group Certified Network Security Practitioner Sample Questions (Q16-Q21):

NEW QUESTION # 16
Which one of the following services is not a UDP-based protocol?

  • A. SNMP
  • B. NTP
  • C. SSH
  • D. IKE

Answer: C

Explanation:
Protocols are defined by their transport layer usage (TCP or UDP), impacting their security and performance characteristics.
Why D is correct: SSH (Secure Shell) uses TCP (port 22) for reliable, connection-oriented communication, unlike the UDP-based options. CNSP contrasts TCP and UDP protocol security.
Why other options are incorrect:
A: SNMP uses UDP (ports 161, 162) for lightweight network management.
B: NTP uses UDP (port 123) for time synchronization.
C: IKE (IPsec key exchange) uses UDP (ports 500, 4500).


NEW QUESTION # 17
What is the response from an open UDP port which is not behind a firewall?

  • A. No response
  • B. A FIN packet
  • C. A SYN packet
  • D. ICMP message showing Port Unreachable

Answer: A

Explanation:
UDP's connectionless nature means it lacks inherent acknowledgment mechanisms, affecting its port response behavior.
Why B is correct: An open UDP port does not respond unless an application explicitly sends a reply. Without a firewall or application response, the sender receives no feedback, per CNSP scanning guidelines.
Why other options are incorrect:
A: ICMP Port Unreachable indicates a closed port, not an open one.
C: SYN packets are TCP-specific, not UDP.
D: FIN packets are also TCP-specific.


NEW QUESTION # 18
A system encrypts data prior to transmitting it over a network, and the system on the other end of the transmission media decrypts it. If the systems are using a symmetric encryption algorithm for encryption and decryption, which of the following statements is true?

  • A. A symmetric encryption algorithm does not use keys to encrypt and decrypt data at both ends of the transmission media.
  • B. A symmetric encryption algorithm uses different keys to encrypt and decrypt data at both ends of the transmission media.
  • C. A symmetric encryption algorithm is an insecure method used to encrypt data transmitted over transmission media.
  • D. A symmetric encryption algorithm uses the same key to encrypt and decrypt data at both ends of the transmission media.

Answer: D

Explanation:
Symmetric encryption is a cryptographic technique where the same key is used for both encryption and decryption processes. In the context of network security, when data is encrypted prior to transmission and decrypted at the receiving end using a symmetric encryption algorithm (e.g., AES or Triple-DES), both the sender and receiver must share and utilize an identical secret key. This key is applied by the sender to transform plaintext into ciphertext and by the receiver to reverse the process, recovering the original plaintext. The efficiency of symmetric encryption makes it ideal for securing large volumes of data transmitted over networks, provided the key is securely distributed and managed.
Why A is correct: Option A accurately describes the fundamental property of symmetric encryption-using a single shared key for both encryption and decryption. This aligns with CNSP documentation, which emphasizes symmetric encryption's role in securing data in transit (e.g., via VPNs or secure file transfers).
Why other options are incorrect:
B: This describes asymmetric encryption (e.g., RSA), where different keys (public and private) are used for encryption and decryption, not symmetric encryption.
C: Symmetric encryption inherently relies on keys; the absence of keys contradicts its definition and operational mechanism.
D: Symmetric encryption is not inherently insecure; its security depends on key strength and management practices, not the algorithm itself. CNSP highlights that algorithms like AES are widely regarded as secure when implemented correctly.


NEW QUESTION # 19
What RID is given to an Administrator account on a Microsoft Windows machine?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: B

Explanation:
In Windows, security principals (users, groups) are identified by a Security Identifier (SID), formatted as S-1-<authority>-<domain>-<RID>. The RID (Relative Identifier) is the final component, unique within a domain or machine. For local accounts:
RID 500: Assigned to the built-in Administrator account on every Windows machine (e.g., S-1-5-21-<machine>-500).
Created during OS install, with full system privileges.
Disabled by default in newer Windows versions (e.g., 10/11) unless explicitly enabled.
RID 501: Guest account (e.g., S-1-5-21-<machine>-501), limited access.
Technical Details:
Stored in SAM (C:WindowsSystem32configSAM).
Enumeration: Tools like wmic useraccount or net user reveal RIDs.
Domain Context: Domain Admins use RID 512, but the question specifies a local machine.
Security Implications: RID 500 is a prime target for brute-forcing or pass-the-hash attacks (e.g., Mimikatz). CNSP likely advises renaming/disabling it (e.g., via GPO).
Why other options are incorrect:
A . 0: Reserved (e.g., Null SID, S-1-0-0), not a user RID.
C . 501: Guest, not Administrator.
D . 100: Invalid; local user RIDs start at 1000 (e.g., custom accounts).
Real-World Context: Post-compromise, attackers query RID 500 (e.g., net user Administrator) for privilege escalation.


NEW QUESTION # 20
If a hash begins with $2a$, what hashing algorithm has been used?

  • A. SHA256
  • B. Blowfish
  • C. SHA512
  • D. MD5

Answer: B

Explanation:
The prefix $2a$ identifies the bcrypt hashing algorithm, which is based on the Blowfish symmetric encryption cipher (developed by Bruce Schneier). Bcrypt is purpose-built for password hashing, incorporating:
Salt: A random string (e.g., 22 Base64 characters) to thwart rainbow table attacks.
Work Factor: A cost parameter (e.g., $2a$10$ means 2
