CCNA Practice Test 1

You are on a Cisco device and using the ping command you cannot access a router elsewhere in the network. After looking at the routing table you have realized there is no route configured that can get you to that device. What type of route can you configure to allow access to the other device?

A local business has been having problems with hackers who are causing disruptions to their business and have proven capable of breaching the local firewalls that they have been using. They have contracted you to help them build a more secure system and in particular they want the system to be a self-contained and managed as possible as they do not have the resources to manage the security internally. What Cisco solution would help them deal with the problems?

Consider a scenario where you are planning the implementation of an enterprise wireless architecture. The network will contain 8 access points connected to a central switch that in return has a connection to a wireless lan controller (WLC). The WLC connects to a Nexus switch that goes to the production network. Today you are making note of the port connections and links required for carrying traffic between all of the devices. Considering the devices being used and their connections, what configurations you will implement?

You have just started with a new company that has plans to grow their network. They also want to switch their network hardware to Cisco so that they have a single supply vendor. As part of the process they need to build an inventory of their endpoints and you need to explain to some junior administrators what they should include as an endpoint. What would best describe the hardware that would be considered an endpoint in the network?

Your boss wants to upgrade the business from using 100Mbps FastEthernet to using Gigabit Ethernet since most of the physical devices and endpoints can support the higher speeds. An additional incentive is that your boss wants to also be able to support PoE for future devices using Power Sourcing Equipment that had been purchased earlier but not put in use yet. However, you notice that the cabling is almost all marked as Cat 5 and you need to make a case that the cabling needs to be upgraded. What would be the benefit and capabilities of upgrading to either Cat 5e or Cat 6?

Part of configuring a switch for VLANs is to verify the connection status for an interface to ensure correct operation. Suppose you want to confirm the VLANs configured on the switch including the VLAN name, operational status, and switchports assigned to the VLANs. What command is most likely to provide you with the information you want to confirm?

Your physical network has been growing substantially over the past year. Automation has helped you manage the network but you have realized the growth requires a more centralized way to manage the network. You have looked at Cisco's Digital Network Architecture Center and want to provide a list of features to your manager to convince them to implement it. What are some of the features provided by the Cisco DNA Center Network Configuration and Operations dashboard?

Suppose you have been contracted by a small business to build out their wireless network. After several meetings with them and determining requirements, you decide the best implementation for them would be a wireless network in infrastructure mode. What best describes the physical infrastructure connections of the small business's WLAN components you set up for them?

You have started as a new network engineer for a small business that is growing and decided they needed someone dedicated to managing their growing network. Until now they have manually added routes or configuration ad hoc until what they wanted working started to work. Upon looking at their devices, which are all Cisco, you notice the routing table has a lot of routes and all of them are Static. They have been having problems lately with some machines being unable to communicate with some other parts of the network and they have been having intermittent issues with network connectivity between different segments of the network. You realize using static routes to link everything together is probably not a good solution as their network has grown. What would be the best way to ensure connectivity between the systems and eliminate the need of using static routes between all the devices?

DHCP has a process that it goes through that starts with the client and results in a client contacting a DHCP server and getting network details like an IP Address, Subnet Mask, Default Gateway, etc. What are the steps in this process?
