The SecOps Group Certified Network Security Practitioner Sample Questions (Q17-Q22):

NEW QUESTION # 17
What ports does an MSSQL server typically use?

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

Answer: D

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 # 18
The application is showing a TLS error message as a result of a website administrator failing to timely renew the TLS certificate. But upon deeper analysis, it appears that the problem is brought on by the expiration of the TLS certificate. Which of the following statements is correct?

A. The communication between the browser and the server is still over TLS.
B. The communication between the browser and the server is now no longer over TLS.

Answer: B

Explanation:
TLS (Transport Layer Security) secures communication (e.g., HTTPS) using certificates, per RFC 8446. A certificate includes:
Validity Period: Start and end dates (e.g., "Not After: March 8, 2025").
Purpose: Authenticates the server and encrypts the session.
Scenario: An expired TLS certificate (e.g., past "Not After" date). Modern browsers (e.g., Chrome, Firefox) validate certificates during the handshake:
ClientHello: Browser initiates TLS.
ServerHello: Server sends its certificate.
Validation: Browser checks expiration, CA trust, etc.
If expired, browsers reject the handshake, displaying errors (e.g., "NET::ERR_CERT_DATE_INVALID"). No session key is negotiated, and communication doesn't proceed over TLS. Users may bypass warnings (e.g., "Advanced > Proceed"), but this is unencrypted or uses a fallback (not standard TLS), breaking security guarantees.
Security Implications: Expired certificates expose sites to MITM attacks, as trust is lost. CNSP likely emphasizes certificate management (e.g., automation with Let's Encrypt) to avoid this.
Why other options are incorrect:
B . The communication is still over TLS: False; an expired certificate halts the TLS handshake in compliant browsers. Legacy systems might negotiate insecurely, but this isn't "TLS" per standards.
Real-World Context: The 2019 Equifax breach partially stemmed from expired certificates missing vulnerabilities.

NEW QUESTION # 19
Which built-in Windows utility can be used to verify the validity of a Kerberos ticket?

A. Netsh
B. Klist
C. Kerbtray
D. Kerberos Manager

Answer: B

Explanation:
Kerberos is the default authentication protocol in Windows Active Directory environments, and tickets are used to prove identity. Verifying ticket validity involves checking their status, expiration, and attributes, which requires a built-in tool available in modern Windows systems.
Why A is correct: Klist is a command-line utility included in Windows (since Vista/2008) that lists cached Kerberos tickets and their details, such as validity period and renewal status. CNSP recognizes it as the standard tool for Kerberos ticket management in security audits.
Why other options are incorrect:
B: Kerbtray is a graphical tool from the Windows Resource Kit, not a built-in utility, and is outdated.
C: Netsh manages network configurations, not Kerberos tickets.
D: "Kerberos Manager" is not a recognized built-in Windows utility; it's a fictitious name.

NEW QUESTION # 20
If you find the 111/TCP port open on a Unix system, what is the next logical step to take?

A. Telnet to the port, send "GET / HTTP/1.0" and gather information from the response.
B. Run "rpcinfo -p <hostname>" to enumerate the RPC services.
C. Telnet to the port to look for a banner.
D. None of the above.

Answer: B

Explanation:
Port 111/TCP is the default port for the RPC (Remote Procedure Call) portmapper service on Unix systems, which registers and manages RPC services.
Why A is correct: Running rpcinfo -p <hostname> queries the portmapper to list all registered RPC services, their programs, versions, and associated ports. This is a logical next step during a security audit or penetration test to identify potential vulnerabilities (e.g., NFS or NIS services). CNSP recommends this command for RPC enumeration.
Why other options are incorrect:
B . Telnet to the port to look for a banner: Telnet might connect, but RPC services don't typically provide a human-readable banner, making this less effective than rpcinfo.
C . Telnet to the port, send "GET / HTTP/1.0" and gather information from the response: Port 111 is not an HTTP service, so an HTTP request is irrelevant and will likely fail.
D . None of the above: Incorrect, as A is a valid and recommended step.

NEW QUESTION # 21
Which of the following algorithms could be used to negotiate a shared encryption key?

A. AES
B. Diffie-Hellman
C. Triple-DES
D. SHA1

Answer: B

Explanation:
Negotiating a shared encryption key involves a process where two parties agree on a secret key over an insecure channel without directly transmitting it. This is distinct from encryption or hashing algorithms, which serve different purposes.
Why C is correct: The Diffie-Hellman (DH) algorithm is a key exchange protocol that enables two parties to establish a shared secret key using mathematical operations (e.g., modular exponentiation). It's widely used in protocols like TLS and IPsec, as noted in CNSP for secure key negotiation.
Why other options are incorrect:
A: Triple-DES is a symmetric encryption algorithm for data encryption, not key negotiation.
B: SHA1 is a hash function for integrity, not key exchange.
D: AES is a symmetric encryption algorithm, not a key exchange mechanism.
