CompTIA N10-009 Dumps Questions Answers

A cable tester is a tool that can help identify issues with the physical cabling, such as breaks or improper terminations, which may prevent the access point from reaching the internet.

MIB (Management Information Base): A MIB is a database used for managing the entities in a communication network. The MIB is used by Simple Network Management Protocol (SNMP) to translate events into a readable format, enabling network administrators to manage and monitor network devices effectively.

Function of MIB: MIBs contain definitions and information about all objects that can be managed on a network using SNMP. These objects are defined using a hierarchical namespace containing object identifiers (OIDs).

IPv4 addresses are divided into classes:

Class A: Supports 16,777,214 hosts (large enterprises).

Class B: Supports 65,534 hosts (medium to large networks).

Class C: Supports 254 hosts (small to medium networks).

Class D: Used for multicast, not for assigning IPs to hosts.

Step-by-step Calculation:

The network will have 150 users initially, with a projected growth of 10 users, totaling 160 users.

Each user has two devices, so 160 × 2 = 320 IP addresses needed.

A Class C subnet has 254 usable IPs by default, which is not sufficient.

A Class B subnet can support thousands of hosts, making it the most appropriate option.

Incorrect Options:

A. Class D: Reserved for multicast, not for host assignments.

C. Class A: Overkill for a network of this size.

D. Class C: Cannot support 320 hosts without subnetting, making Class B the best choice.
