CompTIA Network+ N10-009 Exam Dumps

When signal strength is poor, mobile devices constantly boost their transmission power in an attempt to maintain a stable connection. This results in dropped calls/data and rapid battery drain. Since a repeater was installed, misalignment or misconfiguration could be degrading the signal strength.

A. WPS applies to Wi-Fi, not cellular repeaters.

C. Channel frequency might matter for interference, but signal strength is the most direct cause of the described symptoms.

D. Power budget applies to PoE and wired devices, not mobile phones.

To increase overall security after a recent breach, implementing least privilege network access and central policy management are effective strategies.

Least Privilege Network Access: This principle ensures that users and devices are granted only the access necessary to perform their functions, minimizing the potential for unauthorized access or breaches. By limiting permissions, the risk of an attacker gaining access to critical parts of the network is reduced.

Central Policy Management: Centralized management of security policies allows for consistent and streamlined implementation of security measures across the entire network. This helps in quickly responding to security incidents, ensuring compliance with security protocols, and reducing the chances of misconfigurations.

MIBs (Management Information Bases) define the variables and objects that SNMP can query on a device. If the monitoring server authenticates but cannot interpret the data, it likely lacks the correct MIB for that vendor or model. Importing the proper MIB allows the monitoring server to correctly display device status and metrics.

A. Using a public community string is insecure and not related to missing MIBs.

C. Switchport analyzer (SPAN) captures traffic for packet analysis, not SNMP monitoring.

D. SNMPv3 privacy adds encryption but doesn’t fix missing MIB interpretation.
