If the computer you are using is a laptop that moves from one network to another, what tab can be used to configure a secondary configuration, such as a static IP if a DHCP server cannot be reached? |
Alternate Configuration |
|
Match each item 1)assigns an IP address to a computer when it first attempts to initiate a connection to the network 2)a command that can be used to display the TCP/IP configuration 3)a technique designed to conserve the number of public IP addresses needed by a network 4)commonly used by Linux to pass sign-in information to a remote computer and control that computer over a network 5)a protocol used by various client applications when the application needs to query a database 6)designed to make it easier for users to connect their computers to a wireless network when a hard-to-remember SSID and security key are used 7)identifies a computer and the network to which it belongs, such as www.cengage.com 8)protects data by encrypting it from the time it leaves a remote computer until it reaches a server on a corporate network, using a technique called tunneling. 9)A group of computers on a peer-to-peer network that are sharing resources 10)Used by a computer or other device to determine if an IP address of another computer is on its network or another network |
1)DHCP server 2)ipconfig 3)Network Address Translation (NAT) 4)Secure Shell (SSH) 5)Lightweight Directory Access Protocol (LDAP) 6)Wi-Fi Protected Setup (WPS) 7)Fully Qualified Domain Name (FQDN) 8)virtual private network 9)workgroup 10)subnet mask |

CDMA |
|
What type of IP address is configured by a server when a device first initiates a connection to the network? |
dynamic |
|
True or False: A problem with virtual networks is that data transmitting through them cannot be encrypted and therefore is not secure. |
False |
