The Cisco Certified Network Associate (CCNA 200-301) exam is a 120-minute exam connected with the CCNA certification. Today we are going to talk about how to study CCNA 200 301 with a practice test.

The CCNA 200 301 exam covers the objectives of certification that remain essential for the next step. Very theoretical, these objectives find many application cases in lab exercises.

The operational objective of this document is to identify the components of network topologies and to master IPv4 addressing and IPv6 addressing, both in terms of mask and subnetwork calculations. The guide focuses on the famous Cisco IOS and the GNS3 infrastructure simulator.

\

In the first part, we will try to acquire the fundamentals of network technologies such as TCP /IP and OSI models, the components and architecture concepts of LAN /WAN access networks, in the Data Center and in the cloud (cloud) and, finally, the basics of manipulating decimal, binary and hexadecimal coded identifiers.

In a second part, we discuss how to connect to Cisco devices such as switches or routers and how to understand the Cisco IOS command line environment. This part is not directly verified in the exam, but it is essential for entering configuration and diagnostic operations in real or simulated environments.

The third part focuses on the Internet layer in general, IPv4 addresses and subnet masks, NAT , ICMP, ARP , UDP and TCP . As a diagnostic, several commands for taking information and observing TCP /IP traffic will be proposed.

The last part of this “fundamental” volume would be incomplete without mentioning IPv6. IPv6 is a highly verified subject in CCNA certifications. This part focuses on the recognition and validation of IPv6 addresses, their configuration on interfaces, their verification and diagnosis. Finally, there is a discussion on how to design IPv6 addressing schemes.

Cisco CCNA 200 301 : Network Fundamentals

The CCNA 200-301 practice test also covers the objectives of the certification on network fundamentals but especially on IP connectivity and associated services. It focuses on ÌPv4/IPv6 routing, routing protocols such as OSPF , RIP, and EIGRP , IP services such as NAT , DNS, DHCP , RA, and DHC Pv6.

The practice exam covers the following topics of CCNA 200 301 certification: Network Fundamentals, IP Connectivity and IP Services (in part).

The operational objective of this document is to implement IP connectivity in an enterprise inter-network.

The first part of this pre-aption volume to CCNA focuses on IPv4/IPv6 routing. Routers are at the heart of the Internet network because they are the ones that interconnect endpoints. In this fifth chapter, an introduction to Cisco routers is given, we will learn how to read a router’s IPv4 and IPv6 routing table and distinguish basic routing concepts. Finally, we will learn how to configure, verify and diagnose static routing in Cisco IOS .

A second part presents the infrastructure services that allow this IP connectivity to be “lived well” by the end user. The term “well experienced” connectivity is used here to mean the provision of a quality network access service that is obvious to anyone. DNS , DHCP, NAT and Cisco ACLs are the main chapters developed. Complements for IPv6 address management are also included. We answer the question: how do you implement the Internet connectivity of a corporate network?

The last three sections focus on internal routing protocols. There is a chapter on a classic such as RIP (in version 1 and version 2) as an IETF Distance Vector Routing Protocol. A chapter is devoted to the IETF ’s internal routing protocols with link state: OSP Fv2 and OSP Fv3. Finally, a last chapter presents the Cisco EIGRP optimized distance vector protocol, recently published in RFC Informational. While the current certification only verifies the OSP Fv2 subject, it is recommended to look at all the internal routing protocols, especially EIGRP .

CCNA 200-301 Exam: Network Access

The CCNA 200 301 practice test completes the exam on topics such as Ethernet Switches, VLA Ns, Trunking, Etherchannel, Rapid Spanning-Tree, HSRP , and Wireless Technologies (WLAN). The test covers only one essential topic of CCNA certification: Network Access.

The operational objective is to design a reliable network architecture.

In a first part, we will study the Ethernet LAN access protocol, its cabling, its frame format. The principles of Ethernet switching and LAN architectures will be presented. Finally, we will learn how to configure a Cisco switch and understand the concept of interfaces.

The second part is dedicated to VLAN technologies (IEEE 802.1q) in their Cisco Systems implementation (VTP and DTP ) with “Trunking” and inter-VLAN routing. These chapters complete a first enterprise topology with LAN virtualization.

The next two sections describe LAN protocols that aim to ensure network availability in traditional architectures. The third part explains the fundamentals of the Spanning-Tree and Rapid Spanning-Tree protocols at Layer 2 (L2) level and the physical layer (L1) Etherchannel protocol, which allows links to be aggregated at the logical level. The fourth part tries to answer the question of link robustness in LANs at the default gateway level with HSRP , at Layer 2 (L2) with Spanning-Tree, at Physical Layer (L1) with Etherchannel and at Layer 3 (L3) with IPv4 and IPv6 (static) routing. It uses hierarchical and modular network architecture principles.

The fifth and last part deals with Wireless LAN (WLAN) technologies for local wireless networks, of which the so-called Wi-Fi is a part. It includes a general presentation of the domain, information on normative aspects (IEEE 802.11), on logical topologies and deployment models, on physical aspects (frequency band, non-overlapping, antennas), on client configuration aspects, on WPA security aspects, and finally on management aspects within a local network.

Cisco CCNA 200 301 : Basic Security and Automation and Programmability

CCNA 200 301 also completes the exam on topics such as LAN security, firewall, management protocols such as NTP , Syslog, SNMP , secure device management, and basic network programmability. The book covers the following CCNA certification topics: Basic Security and Automation and Programmability.

The operational objective is to design an agile and secure network architecture.

The first part invites to become aware of the extent of threats on the local network and to consider available countermeasures and best practices especially on Cisco Systems hardware. We will learn how to implement a Port-Security type security measure that aims to limit the number of MAC addresses that can connect to a switch port, but also Deep ARP Inspection (DAI) and DHCP Snooping security.

In the second part, secure management practices such as remote (Telnet, SSH ) and local console configuration, file transfer (TFTP, FTP , SCP) and file verification (MD5) will be discussed. We will also talk about different protocols or solutions that end users are unaware of because they do not need them, but which are useful for network management and monitoring (CDP, LLDP , SYSLOG, NTP , SNMP).

The third part deals with network automation and programmability: on SDN controlled architectures, on the concept of Intent Based Network, automation and automation tools. Finally, we will finish the proposal on the HTTP protocol, CRUD actions, handling HTTP REST AP Is and the processing of outputs in JSON presentation format.

The next three parts aim at demonstrating in theory and practice the concepts of firewall/IDS and site-to-site IPSEC VPN tunnels.
