The SecOps Group Certified Network Security Practitioner Sample Questions (Q50-Q55):
NEW QUESTION # 50
Which of the following services use TCP protocol?
- A. SNMP
- B. IKE
- C. HTTP
- D. NTP
Answer: C
Explanation:
TCP (Transmission Control Protocol) ensures reliable, ordered data delivery via a connection-oriented handshake, contrasting with UDP's lightweight, connectionless approach. Analyzing each service:
C . HTTP (Hypertext Transfer Protocol): Uses TCP (port 80) for web traffic. TCP's reliability ensures HTML, images, etc., arrive intact. HTTPS (TCP 443) extends this with TLS. RFC 2616 mandates TCP.
A . SNMP (Simple Network Management Protocol): Defaults to UDP (port 161) for monitoring devices. UDP's speed suits its lightweight queries, though TCP variants exist (rarely used).
B . NTP (Network Time Protocol): Uses UDP (port 123) per RFC 5905. UDP minimizes latency for time sync, tolerating occasional packet loss.
D . IKE (Internet Key Exchange): Part of IPsec, uses UDP (port 500) per RFC 7296. UDP suits its negotiation phase; TCP isn't standard.
Security Implications: TCP services like HTTP are more prone to state-based attacks (e.g., SYN floods) than UDP counterparts. CNSP likely contrasts TCP vs. UDP in protocol analysis.
Why other options are incorrect:
A, B, D: All default to UDP for efficiency, not TCP's reliability.
Real-World Context: Firewalls prioritize TCP 80/443 rules for HTTP/HTTPS, while UDP 123 is opened for NTP servers.
NEW QUESTION # 51
What is the response from an open UDP port which is behind a firewall (port is open on the firewall)?
- A. A FIN Packet
- B. No response
- C. A SYN Packet
- D. ICMP message showing Port Unreachable
Answer: B
Explanation:
UDP (User Datagram Protocol), per RFC 768, is connectionless, lacking TCP's handshake or acknowledgment mechanisms. When a UDP packet reaches a port:
Closed Port: The host typically sends an ICMP "Destination Port Unreachable" (Type 3, Code 3) unless suppressed (e.g., by firewall or OS settings).
Open Port: If a service is listening (e.g., DNS on 53/UDP), it processes the packet but doesn't inherently reply unless the application protocol requires it (e.g., DNS sends a response).
Scenario: An open UDP port behind a firewall, with the firewall rule allowing traffic (e.g., permit udp any host 10.0.0.1 eq 123). The packet reaches the service, but UDP itself doesn't mandate a response. Most services (e.g., NTP, SNMP) only reply if the packet matches an expected request. In this question's generic context (no specific service), no response is the default, as the firewall permits the packet, and the open port silently accepts it without feedback.
Security Implications: This silence makes UDP ports harder to scan (e.g., Nmap assumes "open|filtered" for no response), but exposed open ports risk amplification attacks (e.g., DNS reflection). CNSP likely contrasts UDP's behavior with TCP for firewall rule crafting.
Why other options are incorrect:
A . ICMP message showing Port Unreachable: Occurs for closed ports, not open ones, unless the service explicitly rejects the packet (rare).
C . A SYN Packet: SYN is TCP-specific (handshake initiation), irrelevant to UDP.
D . A FIN Packet: FIN is TCP-specific (connection closure), not UDP.
Real-World Context: Testing UDP 53 (DNS) with dig @8.8.8.8 +udp yields a response, but generic UDP probes (e.g., nc -u) often get silence.
NEW QUESTION # 52
Which command will perform a DNS zone transfer of the domain "victim.com" from the nameserver at 10.0.0.1?
- A. dig @10.0.0.1 victim.com axfr
- B. dig @10.0.0.1 victim.com arfxr
- C. dig @10.0.0.1 victim.com afxr
- D. dig @10.0.0.1 victim.com axrfr
Answer: A
Explanation:
A DNS zone transfer replicates an entire DNS zone (a collection of DNS records for a domain) from a primary nameserver to a secondary one, typically for redundancy or load balancing. The AXFR (Authoritative Full Zone Transfer) query type, defined in RFC 1035, facilitates this process. The dig (Domain Information Groper) tool, a staple in Linux/Unix environments, is used to query DNS servers. The correct syntax is:
dig @<nameserver> <domain> axfr
Here, dig @10.0.0.1 victim.com axfr instructs dig to request a zone transfer for "victim.com" from the nameserver at 10.0.0.1. The @ symbol specifies the target server, overriding the system's default resolver.
Technical Details:
The AXFR query is sent over TCP (port 53), not UDP, due to the potentially large size of zone data, which exceeds UDP's typical 512-byte limit (pre-EDNS0).
Successful execution requires the nameserver to permit zone transfers from the querying IP, often restricted to trusted secondaries via Access Control Lists (ACLs) for security. If restricted, the server responds with a "REFUSED" error.
Security Implications: Zone transfers expose all DNS records (e.g., A, MX, NS), making them a reconnaissance goldmine for attackers if misconfigured. CNSP likely emphasizes securing DNS servers against unauthorized AXFR requests, using tools like dig to test vulnerabilities.
Why other options are incorrect:
A . dig @10.0.0.1 victim.com axrfr: "axrfr" is a typographical error. The correct query type is "axfr." Executing this would result in a syntax error or an unrecognized query type response from dig.
B . dig @10.0.0.1 victim.com afxr: "afxr" is another typo, not a valid DNS query type per RFC 1035. dig would fail to interpret this, likely outputting an error like "unknown query type." C . dig @10.0.0.1 victim.com arfxr: "arfxr" is also invalid, a jumbled version of "axfr." It holds no meaning in DNS protocol standards and would fail similarly.
Real-World Context: Penetration testers use dig ... axfr to identify misconfigured DNS servers. For example, dig @ns1.example.com example.com axfr might reveal subdomains or internal IPs if not locked down.
NEW QUESTION # 53
How many octets are there in an IPv6 address?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
An IPv6 address, defined in RFC 4291, is a 128-bit address designed to replace IPv4's 32-bit scheme, vastly expanding address space (2
