The SecOps Group Certified Network Security Practitioner Sample Questions (Q52-Q57):

NEW QUESTION # 52
The Management Information Base (MIB) is a collection of object groups that is managed by which service?

A. TACACS
B. NTP
C. SNMP
D. SMTP

Answer: C

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 # 53
What RID is given to an Administrator account on a Microsoft Windows machine?

A. 0
B. 1
C. 2
D. 3

Answer: D

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 # 54
In the context of the SSH (Secure Shell) public-private key authentication mechanism, which key is uploaded to the server and which key is used by the end-user for authentication?

A. The private key is uploaded to the server and the public key is used by the end user for authentication.
B. The public key is uploaded to the server and the private key is used by the end user for authentication.

Answer: B

Explanation:
SSH (Secure Shell), per RFC 4251, uses asymmetric cryptography (e.g., RSA, ECDSA) for secure authentication:
Key Pair:
Public Key: Freely shareable, used to encrypt or verify.
Private Key: Secret, used to decrypt or sign.
Process:
User generates a key pair (e.g., ssh-keygen -t rsa -b 4096).
Public Key is uploaded to the server, appended to ~/.ssh/authorized_keys (e.g., via ssh-copy-id).
Private Key (e.g., ~/.ssh/id_rsa) stays on the user's machine.
Authentication: Client signs a challenge with the private key; server verifies it with the public key.
Technical Details:
Protocol: SSH-2 (RFC 4253) uses a Diffie-Hellman key exchange, then public-key auth.
Files: authorized_keys (server, 0644 perms), private key (client, 0600 perms).
Security: Private key exposure compromises all systems trusting the public key.
Security Implications: CNSP likely stresses key management (e.g., passphrases, rotation) and server-side authorized_keys hardening (e.g., PermitRootLogin no).
Why other options are incorrect:
B: Uploading the private key reverses the model, breaking security-anyone with the server's copy could authenticate as the user. Asymmetric crypto relies on the private key remaining secret.
Real-World Context: GitHub uses SSH public keys for repository access, with private keys on user devices.

NEW QUESTION # 55
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 arfxr
B. dig @10.0.0.1 victim.com axrfr
C. dig @10.0.0.1 victim.com axfr
D. dig @10.0.0.1 victim.com afxr

Answer: C

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 # 56
Which of the following algorithms could be used to negotiate a shared encryption key?

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

Answer: D

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.
