CCNA 1 - Introduction to Networks (ITNv7) Final Exam

Study Notes

Exam Overview

Number of questions: 60
Passing score: 80-100%

Topics Covered

Real-Time Transport Protocol (RTP):
- Common traffic types that use RTP include audio and video streaming.
Wireless Technology:
- Low-power technology with data rate requirements suited for home automation applications is known as Zigbee.
TCP/IP Model Layers:
- The Internet layer is responsible for routing and forwarding messages through an internetwork.
DNS and Server Types:
- DNS servers use record types like A (Address), NS (Name Server), AAAA (IPv6 Address), and MX (Mail Exchange) for providing services.
Proprietary Protocols:
- Proprietary protocols are protocols owned by a particular organization, restricting their use and modification to that entity.
DNS Services:
- Provides name resolution services, translating domain names into IP addresses.
Client Packet Services:
- A packet with a destination port number of 110 requests services from a POP3 mail server.

Network Configuration and Management

IP Configuration Command:
- The command ipconfig is used on a Windows PC to display current IP configuration settings.
Networking Models:
- Sharing a printer in a home network indicates the use of the peer-to-peer networking model.
Characteristics of Viruses:
- A virus replicates itself and spreads by attaching to other files or programs, often causing damage or data loss.

Quality of Service (QoS)

QoS Priorities:
- Highest to lowest priorities for different data types:
  - Audio Conference
  - Database Transactions
  - Web Browsing

Addressing and Protocols

IPv6 Addressing Components:
- Involves matching descriptions to components; specifics depend on provided options.
TCP/IP Layers in File Transfer:
- Transfer involves multiple TCP/IP layers, including application, transport, internet, and network interface layers.
Default Gateway:
- The default gateway for Host H1 should be configured with the IP address from the interface that routes traffic.
Internet Messenger Services:
- Internet Messenger services typically provide real-time messaging capabilities.

Networking Issues and Solutions

Network Planning:
- The smallest network mask that supports 25 devices is /27, accommodating up to 30 usable addresses.
Signal Interference:
- Factors causing signal distortion in copper cabling include electromagnetic interference (EMI) from fluorescent lights and nearby electrical equipment.
MAC Address Resolution:
- Devices without ARP cache mappings obtain destination MAC addresses through ARP requests, seeking to discover the MAC address corresponding to the IP.

Application Data Management

Track Application Sessions:
- PCs use port numbers and session identifiers to manage data flows between multiple applications effectively.

Security Threats

Characteristics of Trojan Horses:
- A Trojan horse disguises itself as a legitimate application to trick users into downloading or executing harmful software.
HTTPS Service:
- HTTPS provides secure communication over a computer network, ensuring data privacy and integrity during transmission.
