CCNA Practice Test 2

You work for a small business that has Windows, Mac, and Linux systems connected to the network. You have recently implemented a new policy that has every system use DHCP for configuring their networks. A small office has three systems used by an engineer for testing and you need to confirm that the new DHCP IP address range is being used by these systems. What commands can you use from the terminal or command line box on these systems to get the IP address?

Consider a scenario where an intern working towards becoming CCNA certified shows you a spanning-tree topology that has four switches in total. Two are designated as Root Bridges and three are designated as the root ports. There are six links and five designated ports and the remaining ports are blocked ports. They want to know if their spanning-tree topology they created will work or have issues. Based on their topology, what area(s) will be of concern operationally?

IPv4 is broken into 5 classes of address referred to as Class A, B, C, D, and E. Class D is for Multicasting and is 224.0.0.1 to 239.255.255.255 and Class E is Experimental from 240.0.0.1 to 255.255.255.255. What are the IP address ranges and number of hosts per network for the first three classes?

You are explaining the differences between standard and extended access control lists to a junior network engineer and why there are particular times when an extended access control list must be used instead of a standard access control list. What advantages do extended access control lists have over standard access control lists?

Consider a scenario where you configured 3 wireless access points in infrastructure mode to use 2.4GHz for a medium sized accounting business last year. In the past six months, this company has hired an additional 20 employees and shortly after adding them to the network, end users have started to report contention and network drop issues. What is the most likely solution you will implement for the accounting business?

Suppose you need a port aggregation protocol to aggregate the bandwidth on the connection between a wireless access controller (WLC) and the wired production switch that provides redundancy overriding the default spanning-tree operation of shutting down one of the links. What port aggregation protocol will you configure to create a one-to-one connection between the WLC and the production switch?

A small business has hired you to help them transition their local network to be cloud based. They want to focus on their business processes versus the day to day technical needs of managing their growing network. They only use a couple of in-house built software applications that are already network enabled and run on their dedicated hardware. However, the developers believe it would be quite feasible to move the software to a cloud based system since their current infrastructure simulates a cloud environment already. The developers and management would like to focus only on their applications in the future and not have to worry about the hardware or any other software management. What Cloud service model would give them the flexibility of running their custom applications while removing the needs of managing even the operating system?

A small business you work for is doing heavy AI research and is expecting to grow substantially in the next quarter and wants to build some redundancy into their internet systems to support future developers. They have multiple Cisco routers and switches and use dynamic routing protocols but they are concerned about the router that is currently configured as the gateway for all the client systems that are currently connected on the network. For this reason they want to minimize the risk from that single point of failure by having a second backup router for the connection to their internet service provider. They use DHCP for all the network connected clients so changing the IP address for the gateway shouldn't be a problem. They currently do not overload the network and only have a single ISP connection so only hardware/routing redundancy is necessary. The current network hardware is all Cisco and the future plans are to stay with Cisco hardware for all network equipment. A manager has written up some information about each of the possible solutions they have identified but they are unsure of the limitations or capabilities of the solutions. Which solution is described best and would meet the requirements necessary to add redundancy to the gateway?

A business has hired you to provide networking knowledge and support to a group of developers who are creating some applications for the business. The entire app is unique to the business and is being build in-house to meet their very specific requirements. The application communicates between each employee who is running it and keeps them all informed as a manufacturing process completes. The specs and digital files that make up the final products have to be transferred from location to location so that the final product meets all the specifications. Missing a step or doing a step out of order would be catastrophic. The developers are debating the benefits of either using TCP or UDP for the network communications in the application for when data transfers from employee to employee and to managers. Which connection type would you recommend?

You have just been promoted to a more senior position managing the network. With the promotion you have been put in charge of managing a half dozen servers that run services like DNS, DHCP, Email, and some web based configuration and management tools. You realize having all these separate servers is both a pain to manage and each server is a single point of failure as there is no configured secondary or backup running systems for the services. You want to minimize the hardware requirements of the servers so you want to go with a virtualization solution and run all the services as separate virtual machines on a single server instead. You have decided that you want to have the hypervisor run on the physical hardware, bare metal, and then have it host the virtual machines in order to maximize performance and functionality. What type of hypervisor would be required to accomplish this?
