CNSP Exam Dumps : Certified Network Security Practitioner (CNSP)

The net localgroup command manages local group memberships on Windows systems, with syntax dictating its action.

Why B is correct:net localgroup Sales Sales_domain /add adds the domain group Sales_domain to the local group Sales, granting its members local group privileges. CNSP covers this for privilege escalation testing.

Why other options are incorrect:

A:Displaying users requires net localgroup Sales without /add.

C:Adding a user requires a username, not a group name like Sales_domain.

D:The reverse (local to domain) uses net group, not net localgroup.

References:CNSP "Windows Group Management" (Section on net Commands) explains net localgroup for adding domain groups.

DDoS (Distributed Denial of Service) attacks aim to overwhelm a target’s resources with excessive traffic, disrupting availability, whereas other attack types target different goals.

Why D is correct:Brute force attacks focus on guessing credentials (e.g., passwords) to gain unauthorized access, not on denying service. CNSP classifies it as an authentication attack, not a DDoS method.

Why other options are incorrect:

A:SYN Flood exhausts TCP connection resources, a classic DDoS attack.

B:NTP Amplification leverages amplified responses to flood targets, a DDoS technique.

C:UDP Flood overwhelms a system with UDP packets, another DDoS method.

References:CNSP "DDoS Attack Types" (Section on Attack Classification) excludes brute force from DDoS categories, listing SYN, NTP, and UDP floods as examples.

Protocols are defined by their transport layer usage (TCP or UDP), impacting their security and performance characteristics.

Why D is correct:SSH (Secure Shell) uses TCP (port 22) for reliable, connection-oriented communication, unlike the UDP-based options. CNSP contrasts TCP and UDP protocol security.

Why other options are incorrect:

A:SNMP uses UDP (ports 161, 162) for lightweight network management.

B:NTP uses UDP (port 123) for time synchronization.

C:IKE (IPsec key exchange) uses UDP (ports 500, 4500).

References:CNSP "Network Protocols" (Section on Transport Layer) identifies SSH as TCP-based, others as UDP.
