CCNA Practice Test 5

Your business just acquired another smaller business in the local area. As part of the transition you have been tasked with moving a lot of their hardware to your location. Upon moving some Cisco devices you found that you could not access them and no one could remember the passwords for the device. You decide it would probably be best to reset the passwords. What is the configuration register value you should set so that on reboot it would not load the startup config?

You have been brought in to diagnose an issue with a medium sized IPv4 Cisco network. The first thing you notice is that the network is very congested and every device is very loaded. They recently switched to using OSPFv2 for dynamic routing and problems started soon after. The routing table appears to be dropping the routes and this tends to happen when the load on the network is at the highest peaks during the day. What is the most likely cause of the issue and what could be done to mitigate the issue?

Switches generally have three logical behaviors for switching data as it comes in one port and goes out another. What are the three behaviors of switches for handling traffic?

You have been working for a small business that has only a few Cisco devices to manage their entire network. Today, your manager has come in and informed you that a contract has been approved that will grow the business by 10 times. They already realize they'll need to greatly expand the networking hardware. What advantages could you demonstrate by recommending they use more automation tools like Cisco DNA Center, Python, and even Software Defined Networking?

You have a medium sized network that have data and voice and users have been coming to you recently complaining about slow-downs in the network and worse, a senior officer of the business has just mentioned they were getting stuttering and cut-outs during their last phone call with a business partner. There are multiple Cisco routers within your local network before it goes out to the internet. You have not used any QoS on the network as it has not been a problem until recently. What QoS configuration would best reduce the risk of issues with voice traffic?

You have started work for a fairly old medium sized Internet business that actually uses Internet routable IPv4 addresses on all their systems. Their internet provider has told them that because of limitations with the number of IPv4 addresses available that they cannot be given any more IPs in the future. Additionally, and of interest to your manager, is that they have asked the business to consider using NAT and private addresses with the promise that doing so would significantly reduce their costs. As part of the process you will need to give new addresses to each device in an IPv4 private range. Because this is a growing business you want to ensure you have enough addresses for future growth. What IPv4 Class B private address range would be valid for the network?

A business wants to replace some cables that have been run years ago between two buildings. The buildings are connected via a conduit and the cables in the conduit are fiber optic. Each end appears to be an SC connector and the writing on the cable says 9/125 where you can read it. The cable is very faded and worn and this is why they need to be replaced. The distance between the two buildings is over five kilometers. What type of Fiber Optic cable has probably been used between the two buildings?

You are configuring a static route via IPv6 between two routers. However, you want the static route to only be used as a backup for the dynamic routing that is already configured on the network. The administrative distance for the dynamic route is 90. What range would be appropriate for setting the administrative distance for the floating static route?

You have been asked to review your networks security policy and you notice there is not much dealing with mitigation techniques actually covered in the document. What are some mitigation techniques that should be covered?

You need to configure some static IPs to names so that a local network can access a server by its name rather than the IP Address. What is the service used by your web browser in order to connect to a website that converts a Fully Qualified Domain Name (FQDN) to an IP address?
