CompTIA Updated N10-009 Exam Questions and Answers by alistair

BNC connectors are commonly used for coaxial cables, including those connecting to external antennas in Wi-Fi, radio, and surveillance systems.

Breakdown of Options:

A. BNC – Correct answer. Used for coaxial cables in wireless and antenna connections.

B. ST – Used for fiber optic cables, not antennas.

C. LC – A fiber optic connector, not for antennas.

D. MPO – Used for multi-fiber optic cables, not RF antennas.

The correct answer is SAML (Security Assertion Markup Language). SAML is an XML-based standard used for single sign-on (SSO) and identity federation. It allows identity providers (IdPs) to share authentication and authorization data with service providers (SPs), passing secure tokens containing user attributes and credentials.

A. IAM (Identity and Access Management) is the broader framework, not specifically XML-based.

B. MFA enforces multiple factors for authentication but does not involve XML assertions.

C. RADIUS is an AAA protocol, but it uses UDP, not XML assertions.

SAML is widely used in federated identity systems, enabling secure authentication across different domains and applications without requiring multiple credentials.

Console Access:

Purpose: Console access to a switch allows administrators to configure and manage the device directly. This is typically done using a terminal emulator program on a computer.

RJ45 Connector:

Common Use: The RJ45 connector is widely used for Ethernet cables and also for console connections to network devices like switches and routers.

Console Cables: Console cables often have an RJ45 connector on one end (for the switch) and a DB9 serial connector on the other end (for the computer).

Comparison with Other Connectors:

ST (Straight Tip): A fiber optic connector used for networking, not for console access.

BNC (Bayonet Neill-Concelman): A connector used for coaxial cable, typically in older network setups and not for console access.

SFP (Small Form-factor Pluggable): A modular transceiver used for network interfaces, not for console access.

Practical Application:

Connection Process: Connect the RJ45 end of the console cable to the console port of the switch. Connect the DB9 end (or USB via adapter) to the computer. Use a terminal emulator (e.g., PuTTY, Tera Term) to access the switch’s command-line interface (CLI).

To monitor server availability, SNMP traps are the best choice. SNMP (Simple Network Management Protocol) allows devices to send alerts (traps) when certain conditions are met, such as server downtime or high resource usage.

Breakdown of Options:

A. Packet capture – Capturing packets provides insights into network traffic but does not actively monitor server availability.

B. Data usage reports – These analyze network traffic consumption but do not indicate whether a server is available or not.

C. SNMP traps – Correct answer. SNMP traps notify administrators of server issues in real time.

D. Configuration monitoring – This tracks configuration changes rather than availability.
