The SecOps Group Certified Network Security Practitioner Sample Questions (Q59-Q64):
NEW QUESTION # 59
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 group "Domain Admins" John /add /domain
- C. net user John /add /domain /admin
- D. net user John "Domain Admins" /add /domain
Answer: B
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 # 60
The Management Information Base (MIB) is a collection of object groups that is managed by which service?
- A. TACACS
- B. SNMP
- C. SMTP
- D. NTP
Answer: B
Explanation:
The Management Information Base (MIB) is a structured database defining manageable objects (e.g., CPU usage, interface status) in a network device. It's part of the SNMP (Simple Network Management Protocol) framework, per RFC 1157, used for monitoring and managing network devices (e.g., routers, switches).
SNMP Mechanics:
MIB Structure: Hierarchical, with Object Identifiers (OIDs) like 1.3.6.1.2.1.1.1.0 (sysDescr).
Ports: UDP 161 (agent), 162 (traps).
Operation: Agents expose MIB data; managers (e.g., Nagios) query it via GET/SET commands.
MIB files (e.g., IF-MIB, HOST-RESOURCES-MIB) are vendor-specific or standardized, parsed by SNMP tools (e.g., snmpwalk). CNSP likely covers SNMP for network monitoring and securing it against enumeration (e.g., weak community strings like "public").
Why other options are incorrect:
A . SMTP (Simple Mail Transfer Protocol): Email delivery (TCP 25), unrelated to MIB or device management.
C . NTP (Network Time Protocol): Time synchronization (UDP 123), not MIB-related.
D . TACACS (Terminal Access Controller Access-Control System): Authentication/authorization (TCP 49), not MIB management.
Real-World Context: SNMP misconfiguration led to the 2018 Cisco switch exploits via exposed MIB data.
NEW QUESTION # 61
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 axrfr
- D. dig @10.0.0.1 victim.com afxr
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 # 62
How many usable TCP/UDP ports are there?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
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
