|
The portion of an IP address common to all nodes on the same network or subnet. |
Network ID |
|
|
Another way of arranging network and host information in an IP address without following the limitations imposed by traditional network class distinctions is known as what? |
CIDR (Classless Interdomain Routing) pronounced cider. |
|
|
This takes the network ID or a host's IP address and follows it with a forward slash (/) followed by the bits that are used for the network ID. |
CIDR notation |
|
|
In the IP address 192.34.89.0/22 What term is used to describe the /22? |
CIDR Block |
|
|
The logical process of combining bits is known as what? |
ANDing A 1 bit combined with a 1 bit results in a 1 bit. A 0 bit combined with any other bit results is a 0. 1=True 0=False |
|
|
The emulation of all or part of a network is known as what? Emulation of a computer, operating system environment, network device, or application. |
Virtualization |
|
|
In virtualization the physical computer is known as what? |
Host |
|
|
What software name makes the most widely implemented virtualization software today? |
VMware |
|
|
To connect to a network a virtual machine needs what? |
Virtual Adapter or vNIC (virtual network interface care) |
|
|
True or False, you can have more than one vNIC on a virtual machine? |
True, the number of vNICs on a VM depends on the limits imposed by the virtualization software. |
|
|
Subnets separates networks into what? |
Multiple logically defined segments |
|
|
The three type of virtualization are: |
Host - The physical computer Guest - The virtual machines Hypervisor - Manages virtual machines |
|
|
Network and broadcast addresses are not used as... |
number of hosts |
|
|
The advantages of using virtualization are: |
Efficient use of resources Cost and energy savings Fault and threat isolation Simplify backups and recovery |
|
|
The disadvantages of using virtualization are: |
Compromised performance Increased complexity Increased licensing cost Single point of failure |

|
|
The first iteration of STP was defined in what IEEE standard? |
802.1d |
|
|
Defined by the IEEE 802.d standard a switching protocol that operates in the Data Link layer to prevent traffic loops. |
STP (Spanning Tree Protocol) |
|
|
Cisco's protocol for exchanging VLAN information over trunks. Allows one switch on a network to centrally manage all VLANs |
VTP (VLAN Trunking Protocol) |
|
|
VTP (VLAN trunking protocol) allows changes to the VLAN database on one switch which is called? |
stack master |
|
|
A BID (Bridge Id) is a combination of what? |
2-byte priority field The bridges MAC address |
|
|
A type of network connection in which a virtual machine (VM) on a host can exchange data with each other and with their host, but they cannot communicate with any nodes beyond the host. |
host-only mode |
