ccna certification expiration.Standards, guidelines, and protocols contain the details defined in the policy. Policies should set several different roles and responsibilities for IT practitioners. SecurityAwareness courses can be used to ensure that all employees within an organization are aware of the security policy and comply with it. Cybersecurity practitioners must be aware ofall legal and ethical codes related to cybersecurity. Protocols for responding to security breaches are also outlined in the security policy.Chapter 1 Experiment PreparationTo successfully complete the experiments in each chapter of this book, you must have the appropriate network equipment (routers, switches, and servers, etc.), software (IOS software and related tools and software), and a reasonable network connection to avoid spending a lot of time to build the network topology for each experiment. This chapter describes the selection of network equipment used in this book, topology construction, and the selection of related software, in an effort to fully satisfy all experiments at the CCNA and CCNP levels related to Cisco routing and switching technologies. Of course, the experiments covered in this book can be completed through the GNS3 simulator, most of the experiments can also be completed through the Cisco PacketTracer simulator, in a sense, it is more convenient to use the simulator to build the experimental environment.1.1 Experimental Topology ConstructionIn order to complete the experiments in this book, different network topologies need to be constructed, which would take a lot of time if the network topology is built on an ad hoc basis each time. For this reason, we designed a powerful network topology that can satisfy the experiments related to the routing and switching contents of CCNA and CCNP courses. The experimental topology can be used by one person or 1.4 people working together to complete the experiments.The experimental topology (Ethernet connection part) designed in this book is shown in Figure 1-1 (the figure does not include the terminal access server and the connection of each device).
