CCNA Practice Test 8

A small business owner has had a network attack that caused some damage to their business processes but did not compromise data. The owner wants to get revenge on the attacker and you have been asked to help. You explain that a reactive approach to the attack would probably not be beneficial and could actually cause more harm and you instead suggest the business take a proactive security posture to prevent a hacker from causing harm again in the future. What are three basic security program components from Cisco that are proactive for security?

Your company recently expanded their network with a small branch office location and you are responsible for setting up the newly purchased switches for VLANs and supporting VLAN traffic. Your task is to configure VLANs and trunks. You have created VLAN 20 and are required to specify that the port will function at Layer 2, and places the port in VLAN access mode. What command and which configuration mode would complete this task?

You have bene asked to configure a VPN from your business to a business across the country. Your business has recently partnered with this other business for a large government contract and they have multiple servers and resources that must be accessible with each other. The VPN connection must always be up and must allow both networks to communicate securely with each other and access resources from either end. What VPN technology should be used to connect these networks?

Within your OSPFv2 network you have multiple point-to-point and multiaccess networks managed by Cisco devices. The OSPFv2 election has made some devices Designated Routers (DR) and has set others up as Backup Designed Routers (BDR). What would the other devices in the multiaccess network be set to if they are not a DR or BDR?

You have been tasked with automating your network hardware infrastructure for a medium sized business that is growing. Part of the upgrade will switch to using a SDN architecture in a new private cloud. What terminology represents the infrastructure like the physical switches, routers, cables, etc of a software defined architecture?

You have been monitoring traffic on some systems and the network and a manager asks you about all the traffic starting with fe80 that they see when they take a look at your screen running wireshark. What type of IPv6 network traffic starts with fe80?

You are working with a software developer building an application to automate a small networking task that has been taking a lot of your time doing manually. Unfortunately, the developer is not that familiar with networking or networking protocols but can use components to make everything work. The programmer has come to you since the code is returning a lot of numerical values like 200, 201, 404, 401, 503, etc. What would give the programmer an overview of the different meanings and groupings of the responses?

A large business has hired you as a consultant to help them decide which wireless infrastructure they want to implement. They currently do not have any wireless but need it to support a variety of business growth plans. They deal with medical and personal data so the data must be protected as well as protecting any access to the physical network. They expect about 200 users and they would like to use their current RADIUS infrastructure used for authentication and in the future will want to implement biometrics. Which Wireless security protocol would you recommend then focus on for their infrastructure?

Consider a scenario where you are configuring a trunk link between two access layer switches to carry traffic for 12 VLANs. Today you have an intern who is working towards obtaining their CCNA certification with you and they want to understand how the native VLAN operates on switches and asks which attributes are inherent to 802.1Q native VLANs. What responses are you most likely to provide the intern?

You have been given control over a very diverse and large network consisting of many Cisco devices that have been cobbled together from multiple smaller businesses over a series of years from acquisitions. Unfortunately, each smaller network had used their own choices for the Dynamic Routing Protocols used on their portion of the network. This means the Routing Protocol metric is calculated differently depending on the network. As part of the process of identifying and documenting the network for future planning and upgrades you need to identify the different ways the Routing Protocol Metric has been used. What are the metric calculation for the RIP, RIPv2, EIGRP, and OSPF calculations?
