Myth Busters and the CCDE Practical Exam

cisco ccde certification

Cisco CCDE certification and CompTIA Network + both position themselves as a credentials of entry-level network certification. However, there are many differences between these two credentials. Where the CompTIA Network + is extensive and capture some information about most types of networks and network technology, CCDE is narrower and deeper, and dig deeper into the specifics involved in choosing, configuring, implementing, and wireless LAN Cisco, and WAN connections basic. This article discusses the question of whether the CompTIA + network is a better startup credential or whether the candidate must pursue a network technician Cisco certified entry (CCDE).

One type of question that I often enter from IT workers is in the level of good starter certification. In particular, I am often asked whether the CompTIA + network is a better startup credential, or whether the candidate must go after the Cisco certified entry network technician (CCDE). The answer to the question is very dependent on whether the certification candidate wants or plans to work in a Cisco-based network environment, or if they are only looking for a good general introduction to network conditions and concepts, tools, and technology. Those who lead to the Cisco line (or who just want to try it) will best fit the pursuit of CCens as the first step, while those who might be less sure where they go or who only want a good general image of the network must pursue network +.

Understand network +

CompTIA takes a broader view of the network than Cisco, in some ways, but the coverage of individual topics tends to be more shallow too. Thus, it makes sense to think of a network + like a few miles wide, but maybe just a few feet in the range of the surrounded material.

Here's a brief summary and very condensed with a domain name:

Network Technologies: Protocol and General Network Services from TCP / IP Suite, TCP and UDP Default Port numbers, overcome the format for IPv4, IPv6, and Mac addresses, discussions about addressing technology (subnetting, CIDR, PAT, and SO ON), routing protocols IPv4 and IPv6, general discussions on routing, and reviewing various wireless standards for communication, authentication, and encryption.

Network media and topology: standard cable types and properties such as transmission speed, distance, duplexing, noise immunity, and frequencies used; General cable connector type; And general physical network topologies (stars, mesh, buses, rings, and so on). Many wiring standards are borne, along with LAN and WAN technology types and properties plus distribution systems and cable components.

Network devices: include gear gear network from hubs, repeaters, modems, network interfaces, and media converters, to switch, bridges, wireless access points, routers, firewalls, and DHCP servers. The function of special network devices comes next (various switches, intrusion detection and prevention system, load balancer, DNS server, etc.). Switch Details (Power Over Ethernet, Spanning Trees, Virtual Lans, Trunking, Port Mirroring and Authentication) Get deeper coverage, and there is a primary on the implementation of basic wireless networks here too.

Network Management: Describes management in seven layers of OSI models, including configuration management and documentation, and explains how to use that documentation to evaluate networks. The remaining parts deal with network monitoring for performance and connectivity, methods for network performance optimization, network problem solving methods and distinctive problem solving cases.

Understanding CCDE

Given that Cisco is behind the ocens, it should not be surprising that this credentials are oriented to Cisco and focus, first, especially, and last. The Cisco exam name is related to ICND1 (shortens to connect the Cisco network device part 1), which directly emphasizes the cisco centrisity. (Note, as with CompTIA + network, candidates must register with the Cisco site to access details about its certification; because the certification sought to be more advanced, Cisco Cert candidates must also meet the prerequisites [MD] often in other forms, more junior credentials [MD ] To get access to the aim of the exam, silical, sample practice questions, and other exam information).

Here Overview of the test topic for this credentials is summarized from the Cisco Blue Print page for this credentials:

Explain the operation of the data network: the purpose of translation and function of various network devices, then select components to meet basic network specifications. Use the OSI and TCP / IP models and related protocols to explain the network data flow; Describe the general network and web application; Describe the purpose and basic operation of the protocol in the OSI and TCP / IP models. Explain the impact of applications such as VoIP on the network; interpret network diagrams; Track the road between two hosts on the network; distinguish between operations and features of LAN and WAN.

Apply Small Switched Network: Select the appropriate media, cable, ports and connectors to interconnect switches, network devices, and hosts. Explain access control technology and media for Ethernet types; Explain network segmentation and basic traffic management concepts; Explain the operation of the Cisco switch and the basic switching concept. Do, save, and verify the initial switch configuration assignment; Verify network status and switch operations using basic utilities; Apply and verify the security of the basic switch; Work through the media, configuration, automatic negotiation, and hardware failure on the activated network.

Applying IP addressing schemes and IP services to meet network requirements for small branch offices: Explain the needs and roles that address the game on the network; Create and apply the addressing scheme to the network. Set and verify the valid IP address for the host, server, and network device on the LAN. Explain the basic use and NAT operation on small networks with one internet link; Explain and verify DNS operations; Explain the benefits and operation of personal and public IP addresses. Activate NAT for small networks with single ISPs and connections using HR; Operation verification using CLI and Ping. Configure, verify, and solve DHCP and DNS operating problems on the router; Apply static and dynamic addressing services for LAN hosts; Identify and correct IP addressing problems.
