CCST Networking Study Guide - Introduction

Introduction:

The Cisco Certified Support Technician (CCST) certification is a program designed to validate the skills required to successfully provide support for Cisco networking products. The CCST certification focuses on the knowledge and skills needed to troubleshoot and resolve issues with Cisco networking devices, such as routers, switches, and wireless controllers.

The CCST Networking exam is a test that candidates must pass in order to earn the CCST certification. The exam covers a range of topics related to Cisco networking, including network fundamentals, LAN switching, IP routing, wireless networking, and network security. The exam also includes troubleshooting scenarios that require candidates to use their knowledge and skills to diagnose and resolve issues with Cisco networking devices.

The CCST Networking exam is a multiple-choice exam that is delivered online through Pearson VUE testing centers. Candidates have 90 minutes to complete the exam, and the passing score is 800 out of 1000.

To prepare for the CCST Networking exam, candidates should have a strong understanding of Cisco networking technologies and experience working with Cisco networking devices. Cisco recommends that candidates have at least six months of experience working with Cisco networking devices before taking the exam. Candidates can also prepare for the exam by taking the Cisco Support Technician (CST) course, which covers the knowledge and skills needed to pass the CCST Networking exam.

The CCST Networking exam covers a range of topics related to Cisco networking, including:

1. Network Fundamentals: This section covers basic networking concepts such as OSI and TCP/IP models, IP addressing, subnetting, and VLANs.

2. LAN Switching: This section covers LAN switching technologies such as Ethernet, STP, RSTP, and VTP. Candidates will also be tested on their ability to configure and troubleshoot LAN switching issues.

3. IP Routing: This section covers IP routing technologies such as OSPF, EIGRP, and BGP. Candidates will also be tested on their ability to configure and troubleshoot IP routing issues.

4. Wireless Networking: This section covers wireless networking technologies such as 802.11 standards, wireless security, and WLAN controllers. Candidates will also be tested on their ability to configure and troubleshoot wireless networking issues.

5. Network Security: This section covers network security concepts such as AAA, firewalls, and VPNs. Candidates will also be tested on their ability to configure and troubleshoot network security issues.

6. Troubleshooting: This section tests candidates' ability to troubleshoot and resolve issues with Cisco networking devices. Candidates will be presented with scenarios and will need to use their knowledge and skills to diagnose and resolve the issues.

Candidates should have a strong understanding of these topics and be able to apply their knowledge and skills to troubleshoot and resolve issues with Cisco networking devices. Cisco recommends that candidates have at least six months of experience working with Cisco networking devices before taking the CCST Networking exam.

1. Network Fundamentals

Network Fundamentals is one of the topics covered under the CCST Networking exam. This section covers the basic concepts and principles of computer networking, including the following:

1. OSI Model: The OSI (Open Systems Interconnection) model is a conceptual framework that describes how communication between two devices on a network takes place. The OSI model has seven layers, each of which performs a specific function in the communication process.

2. TCP/IP Model: The TCP/IP (Transmission Control Protocol/Internet Protocol) model is a suite of communication protocols used to interconnect network devices on the internet. The TCP/IP model has four layers, each of which corresponds to one or more layers of the OSI model.

3. IP Addressing: IP (Internet Protocol) addressing is a system used to assign unique addresses to devices on a network. IP addresses are used to identify devices on a network and to route data packets between devices.

4. Subnetting: Subnetting is the process of dividing a larger network into smaller subnetworks. Subnetting is used to improve network performance and security, and to simplify network management.

5. VLANs: VLANs (Virtual Local Area Networks) are used to create separate logical networks within a physical network. VLANs are used to improve network performance and security, and to simplify network management.

6. Ethernet: Ethernet is a local area networking (LAN) technology used to connect devices on a network. Ethernet uses a star topology and supports data transfer rates of up to 100 Gbps.

7. Switching: Switching is the process of forwarding data packets between devices on a network. Switches are used to create separate collision domains and to improve network performance.

Candidates preparing for the CCST Networking exam should have a strong understanding of these network fundamentals concepts and be able to apply them to troubleshoot and resolve issues with Cisco networking devices. Cisco provides a range of resources to help candidates prepare for the exam, including study guides, practice exams, and training courses.

CCST Networking - Self Evaluation Questions

 Given below are some of the questions for self assessment with respect to CCST Networking exam . Check them out. Question 1: Which of the following devices operates at the data link layer (Layer 2) of the OSI model? A. Router B. Switch C. Hub D. Firewall Answer: B. Switch Explanation: A switch operates at the data link layer (Layer 2) of the OSI model. It is used to forward data based on MAC addresses. Question 2: What is the main function of a router in a network? A. To segment a network into multiple broadcast domains B. To connect multiple devices within a single network segment C. To filter traffic based on IP addresses D. To repeat and amplify signals in a network Answer: A. To segment a network into multiple broadcast domains Explanation: Routers operate at the network layer (Layer 3) and are responsible for forwarding data packets between different networks, thus segmenting a network into multiple broadcast domains. Question 3: Which protocol is responsible for dynamicall

CCST Networking Exam Notes - Network Fundamentals

Networking Fundamentals: This topic covers the basic concepts and principles of networking, including network topologies, protocols, and devices. It's the foundation topic in CCST Networking exam domains. TCP/IP Model TCP/IP (Transmission Control Protocol/Internet Protocol) is a set of networking protocols that is used to communicate and exchange data between devices on a network or the Internet. It is the most widely used and dominant networking protocol in the world, and forms the basis of the Internet and many other types of networks. TCP/IP is a layered protocol, meaning that it is composed of several different protocols that are organized into a stack. The four main layers of the TCP/IP protocol stack are: 1. Application Layer: This layer is responsible for providing services and applications to users, such as web browsers, email clients, and file transfer tools. 2. Transport Layer: This layer is responsible for ensuring the reliable and error-free delivery of data between dev
