The SecOps Group Certified Network Security Practitioner Sample Questions (Q56-Q61):

NEW QUESTION # 56
What ports does an MSSQL server typically use?

  • A. 1433/TCP, 1434/UDP, and 1434/TCP
  • B. 1433/TCP, 2433/UDP, and 3433/TCP
  • C. 1433/TCP, 2433/UDP, and 1434/TCP
  • D. 1533/TCP, 1434/UDP, and 2434/TCP

Answer: A

Explanation:
Microsoft SQL Server (MSSQL) relies on specific ports for its core services, as defined by Microsoft and registered with IANA:
1433/TCP: The default port for the SQL Server Database Engine. Clients connect here for querying databases (e.g., via ODBC or JDBC). It's a well-known port, making it a frequent target for attacks if exposed.
1434/UDP: Used by the SQL Server Browser Service, which listens for incoming requests and redirects clients to the correct port/instance (especially for named instances). It's critical for discovering dynamic ports when 1433 isn't used.
1434/TCP: Less commonly highlighted but used in some configurations, such as dedicated admin connections (DAC) or when the Browser Service responds over TCP for specific instances. While 1433/TCP is the primary engine port, 1434/TCP can be involved in multi-instance setups.
Technical Details:
Ports can be customized (e.g., via SQL Server Configuration Manager), but these are defaults.
Named instances often use dynamic ports (allocated from the ephemeral range), with the Browser Service (1434/UDP) guiding clients to them.
Firewalls must allow these ports for MSSQL to function externally, posing risks if not secured (e.g., brute-force attacks on 1433/TCP).
Security Implications: CNSP likely covers MSSQL port security, as vulnerabilities like SQL Slammer (2003) exploited 1434/UDP misconfigurations. Hardening includes restricting access, changing defaults, and monitoring traffic.
Why other options are incorrect:
A . 1433/TCP, 2433/UDP, 3433/TCP: 2433/UDP and 3433/TCP are not MSSQL standards; they're likely typos or unrelated ports.
C . 1433/TCP, 2433/UDP, 1434/TCP: 2433/UDP is incorrect; 1434/UDP is the Browser Service port.
D . 1533/TCP, 1434/UDP, 2434/TCP: 1533/TCP and 2434/TCP aren't associated with MSSQL; they deviate from documented defaults.
Real-World Context: Tools like netstat -an | find "1433" on Windows confirm MSSQL's port usage during audits.


NEW QUESTION # 57
An 'EICAR' file can be used to?

  • A. Test the encryption algorithms
  • B. Test the response of an antivirus program

Answer: B

Explanation:
The EICAR test file is a standardized tool in security testing, designed for a specific purpose.
Why A is correct: The EICAR file (a 68-byte string) triggers antivirus detection without harm, testing response capabilities. CNSP recommends it for AV validation.
Why B is incorrect: It has no role in testing encryption; it's solely for AV functionality.


NEW QUESTION # 58
On a Microsoft Windows Operating System, what does the following command do?
net localgroup administrators

  • A. Displays the local administrators group on the computer
  • B. List domain admin users for the current domain

Answer: A

Explanation:
The net command in Windows is a legacy tool for managing users, groups, and network resources. The subcommand net localgroup <groupname> displays information about a specified local group on the machine where it's run. Specifically:
net localgroup administrators lists all members (users and groups) of the local Administrators group on the current computer.
The local Administrators group grants elevated privileges (e.g., installing software, modifying system files) on that machine only, not domain-wide.
Output Example:
Alias name administrators
Comment Administrators have complete and unrestricted access to the computer Members
------------------------------------------------------------------------------- Administrator Domain Admins The command completed successfully.
Technical Details:
Local groups are stored in the Security Accounts Manager (SAM) database (e.g., C:WindowsSystem32configSAM).
This differs from domain groups (e.g., Domain Admins), managed via Active Directory.
Security Implications: Enumerating local admins is a reconnaissance step in penetration testing (e.g., to escalate privileges). CNSP likely covers this command for auditing and securing Windows systems.
Why other options are incorrect:
A . List domain admin users for the current domain: This requires net group "Domain Admins" /domain, which queries the domain controller, not the local SAM. net localgroup is strictly local.
Real-World Context: Attackers use this command post-compromise (e.g., via PsExec) to identify privilege escalation targets.


NEW QUESTION # 59
Which of the following is a valid DNS record type?

  • A. SRV record
  • B. NAPTR record
  • C. All of the above
  • D. TXT 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 # 60
How many usable TCP/UDP ports are there?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: A

Explanation:
TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) port numbers are defined by a 16-bit field in their packet headers, as specified in RFC 793 (TCP) and RFC 768 (UDP). A 16-bit integer ranges from 0 to 65,535, yielding a total of 65,536 possible ports (2
