CompTIA N10-008 - Questions & Answers

Configuring the log settings to send firewall logs to a central syslog server is a crucial step in hardening and monitoring the security of the firewalls. This allows for centralized logging and analysis of firewall events, which is important for detecting and responding to security incidents, as well as for auditing and compliance purposes

The seven layers of the OSI model are:

Physical layer: responsible for transmitting raw data bits over a physical medium such as a cable.
Data Link layer: provides error-free transmission of data frames over the physical layer.
Network layer: responsible for routing and addressing of data packets.
Transport layer: provides reliable end-to-end communication between applications.
Session layer: establishes, manages, and terminates communication sessions between applications.
Presentation layer: formats and encrypts data for network transmission.
Application layer: provides the interface between the application and the network for communication.

STP (Spanning Tree Protocol) A switching protocol that prevents network loops by dynamically disabling links as needed.

Received Signal Strength Indication (RSSI) is a measurement of the strength of a received radio signal. It is measured as a negative number on a logarithmic scale, which means that the closer to 0 the RSSI is, the better the signal. Clearly, AP 1 and AP 2 has channel/frequency overlap that causes the RF signals to interfere with each other.

BGP (Border Gateway Protocol) is the correct answer as it is used to exchange route information between public autonomous systems.

An OTDR (Optical Time Domain Reflectometer) works by emitting a short pulse of light into the fiber and then measuring the backscattered light as a function of time. By analyzing the backscattered light, the OTDR can determine the location and characteristics of events, such as bends, breaks, or splices, along the fiber.

TACACS+ is used to authenticate users and authorize access to network resources. This protocol provides greater network security by encrypting the authentication credentials and reducing the risk of unauthorized access. According to the CompTIA Network+ Study Manual, "TACACS+ is an authentication protocol used to centralize authentication and authorization for network devices. It is a more secure alternative to Telnet for handling logins and for granting privileges to users."

Remote Desktop Protocol is used to installed software while FTP is for file transfer

Qualityof Service (QoS) can be configured for latency-sensitive applications, such as Voice over IP (VoIP).
