CCNA Practice Test 9

To protect against unauthorized access to devices and confidential information, networks require the implementation of some security best practices when it comes to VLAN configuration. Today you are researching the operation and best practices when it comes to the default VLAN 1 within the network infrastructure. What can be said about the default VLAN?

Consider a scenario where you have been tasked with configuring support for voice and data on an end user port on switch NYCORE1. The requirement is to support IP phone data as well as a personal computer on the same access port. The data VLAN will be designated as 5 and the voice VLAN 10 and you have entered into interface configuration mode for fa1/0/15. Considering the requirements, how will you configure the NYCORE1 interface to support traffic for the IP phone and personal computer?

Consider a scenario where you have configured the spanning-tree protocol in a new switched network and this week you are looking at optimizing the spanning-tree protocol with the use of portfast. You will be enabling it globally and all ports have been designated as access ports. What configuration can be used to deploy Portfast?

You are configuring a small business network that only has two Cisco network devices. To do this you have decided to configure a network route between the two devices to facilitate communication. From the global configuration mode you have entered: 01. ip route 172.16.16.0 255.255.255.0 192.168.16.3 What part of this command represents the next hop in the route?

What is the advantage of using Cisco PVST+ over PVST?

Which of the following is NOT TRUE about Private VLAN's?

A junior engineer is viewing packets as they move through the network to investigate an issue with routing from a Cisco device. They are having problems understanding how the data moves from one device to another to traverse the network. What part of the data changes as the data moves from device to device to facilitate the routing of the data through the network?

You have a medium sized network that uses EIGRP for dynamic routing and for the most part this has worked well. However, the CTO wants to have more redundancy added to the network to minimize failures. The network uses IPv4 and IPv6 and, because of high traffic, generally has multiple routes between systems. What would be a good backup solution to ensure any issues with EIGRP would not prevent the network from working?

You are trying to determine how traffic flows through your network and have one device that has two routes to another network. The one route is a /26 and the other is a /24 subnet in the IPv4 routing table. Which interface would be used if the destination IP can be accessed by either route?

An employee seems to be having problems communicating over the network. Pings are not working or working intermittently and even simple protocols like FTP are reporting errors when trying to do file transfers. Web viewing is extremely slow for some reason. You have connected to the Cisco device that is physically connected to the employee’s endpoint system and know the interface is fa1/0/1. What command can show you the collision counts, duplex mode, media type, packets, configured port speed, and errors that have been identified by the Cisco device for that interface?
