CompTIA Updated N10-009 Exam Questions and Answers by claudia

If the administrator is concerned a new discovery tool could disrupt operations, the safest option is to configure scheduled scans. Network+ (N10-009) operations guidance emphasizes minimizing impact by running potentially noisy tasks (discovery, vulnerability checks, inventory scans) during defined maintenance windows or off-peak hours. A scheduled scan allows controlled timing, predictable load, and easier coordination with change management, monitoring, and support teams. This reduces the risk of saturating links, overwhelming devices with queries, or triggering alerts during business-critical periods.

Ad hoc scanning is on-demand and may occur at any time, which increases the chance of disruption if run during peak usage. Authenticated versus unauthenticated describes whether the scanner uses credentials to log into systems for deeper visibility; that choice affects depth and accuracy, but it doesn’t directly address when scanning occurs to reduce business impact. An authenticated scan can still be disruptive if run at the wrong time, and an unauthenticated scan can still generate significant traffic. Since the key concern is operational disruption, controlling scan timing via scheduled scans is the best mitigation.

===========

LDAP (Lightweight Directory Access Protocol) uses port 389 for standard connections and port 636 for LDAP over SSL (LDAPS), which secures directory service communication.

Breakdown of Options:

A. 22 – SSH port, not used for directory services.

B. 389 – Used for LDAP, but not encrypted.

C. 445 – Used for SMB file sharing, not LDAP.

D. 636 – Correct answer. LDAPS (LDAP over SSL/TLS) secures directory authentication.

To support at least 260 hosts, you need at least 512 total IP addresses (accounting for network/broadcast overhead).

/23 (255.255.254.0) gives 510 usable IPs, ideal for 260 devices with minimal waste.

/24 (255.255.255.0) gives only 254 usable — not enough.

/22 (1022 usable) and /21 (2046 usable) would work but result in significant address waste.

A mesh network is the best solution for providing reliable wireless service to public safety vehicles. In a mesh network, each node (vehicle) can connect to multiple other nodes, providing multiple paths for data to travel. This enhances reliability and redundancy, ensuring continuous connectivity even if one or more nodes fail. Mesh networks are highly resilient and are well-suited for dynamic and mobile environments such as public safety operations.References: CompTIA Network+ study materials.
