Review 3 Flashcards
Which feature prevents switching loops and ensures that there is only a single active path between any two switches?
Spanning Tree Protocol (STP)
How many bits are in a MAC address?
48
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?
Configure port security on the switch.
Which level of the OSI model does a Layer 2 switch operate at?
Layer 2 (Data Link)
Which of the following is a device that can send and receive data simultaneously?
Unmanaged
Full-duplex
Honeypot
Managed
Full-duplex
Which of the following switch features allows you to configure how the switch’s MAC address table is filled?
Question options:
Spanning Tree Protocol
Auto-negotiation
Port security
Port mirroring
Port security
You are configuring a switch so that you can manage it using PuTTY from the same network segment. On the switch, you enter the following commands:
switch#config terminal
switch(config)#interface vlan 1
switch(config-if)#ip address 192.168.1.10 255.255.255.0
Will this configuration work?
No. The no shutdown command needs to be entered.
When using a program such as PuTTY to create a console connection with a switch, which terminal emulation settings would you use?

Network Discovery Protocol (NDP)
Which of the following BEST describes port aggregation?
Question options:
Multiple ports linked together and used as a single logical port.
IEEE network standard 802.3.
Multiple VLANs traveling through a single port.
A priority-based flow control that allows you to prioritize network traffic.
Multiple ports linked together and used as a single logical port.
In the following MAC address, what is the Organizationally Unique Identifier (OUI)?
FF-11-EE-22-DD-33
FF-11-EE
You manage a network with two switches. The switches are connected together through their Gigabit Ethernet uplink ports.
You define VLAN 1 and VLAN 2 on each switch. A device on the first switch in VLAN 1 needs to communicate with a device on the second switch in VLAN 1.
What should you configure to allow communication between these two devices through the switches?
Trunking
Layer 3 switching
Bonding
Spanning Tree
Trunking
