Networking 3/4 7.1-7.4 Test Review

Which level of the OSI model does a Layer 2 switch operate at?

• Data Link layer

• Transportation layer

• Network layer

• Session layer

Which of the following is a device that can send and receive data simultaneously?

• Honeypot

• Unmanaged

• Managed

• Full-duplex

Which of the following scenarios would typically utilize 802.1x authentication?

• Controlling access through a router.

• Authenticating VPN users through the internet.

• Controlling access through a switch.

• Authenticating remote access clients.

You are the network administrator for a city library. Throughout the library are several groups of computers that provide public access to the internet. Supervision of these computers has been difficult. You've had problems with patrons bringing personal laptops into the library and disconnecting the network cables from the library computers to connect their laptops to the internet. The library computers are in groups of four. Each group of four computers is connected to a hub that's connected to the library network through an access port on a switch. You want to restrict access to the network so that only library computers are permitted connectivity to the internet. What can you do?

• Create static MAC addresses for each computer and associate each address with a VLAN.

• Create a VLAN for each group of four computers.

• Configure port security on the switch.

• Remove the hub and place each library computer on its own access port.

Drag each description on the left to the appropriate switch attack type on the right.

Groups:

(a) ARP spoofing/poisoning

,

(b) Dynamic Trunking Protocol

,

(c) MAC flooding

What does the ip address dhcp command allow you to do?

• Configure a switch to act as a DHCP server.

• Specify the DHCP relay server for forwarding DHCP packets

• Configure a switch to obtain an IP address from a DHCP server.

• Send the DHCP server address for all connected devices.

You manage a single subnet with three switches. The switches are connected to provide redundant paths between themselves. Which feature prevents switching loops and ensures that there is only a single active path between any two switches?

• Spanning Tree

• Trunking

• PoE

• 802.1x

Which of the following BEST describes port aggregation?

• Multiple VLANs traveling through a single port.

• IEEE network standard 802.3.

• Multiple ports linked together and used as a single logical port.

• A priority-based flow control that allows you to prioritize network traffic.

An attacker hides his computer's identity by impersonating another device on a network. Which of the following attacks did the attacker MOST likely perform?

• MAC spoofing attack

• VLAN hopping attack

• ARP spoofing attack

• DTP attack

In which type of device is a MAC address table stored?

• Router

• Switch

• Hub

• Repeater
