CompTiA A+ Chapter 7: Understanding TCP/IP Flashcards
WHAT ARE TWO CRITICAL TIP/IP YOU SHOULD BEAWARE UP
- DYNAMIC HOST CONFIGURATION PROTOCOL (DHCP)
- DOMAIN NAME SYSTEM (DNS)
PAGE 314
DHCP- CONFIGURE TO PROVIDE WHAT
CONFIGURED TO PROVIDE IP CONIFIGURATION INFORMATION TO CLIENTS AUTOMATIICALLY AND WHAT IS CALLED A LEASE
PAGE 314
WHAT IS A LEASE
INFORMATION THAT IS NOT PERMANTLY GRANTED TO THE CLIENT COMPUTER AND THE CLIENT MUST PERIODICALLY REQUEST A NEW LEASE
PAGE 314
WHAT ARE SOME ELEMENT THAT ARE PROVIDED BY A LEASE
- IP ADDRESS
- SUBNET MASK
- DEFAULT GATEWAY ( THE DOOR TO THE OUTSIDE WORLD)
- DNS SERVER ADDRESS
PAGE 315
WHEN A DHCP BOOT UP, IT SENDS OUT WHAT
DHCP DISCOVER
PAGE 315
TO USE A DHCP YOU NEED TO WHAT
TO USE A DHCP YOU NEED TO DO FROM THE CLIENT SIDE IS CONFIGURE IT TO OBTAIN IP ADDRESSING INFORMATION AUTOMATICALLY
PAGE 315
WHAT IS THE PRIMARY FUNCTION OF DNS
TO RESOLVE HOSTNAME TO IP ADRESSES
PAGE315
IF THE DNS DOES NOT KNOW THE ADDRESS OF THE HOST YOU ARE SEEKING, IT DOES WHAT
IT HS THE ABILITY TO QUERY OTHER DNS SERVERS TO HELP ANSWER THE REQUEST
PAGE 315
ALL OF THE ADDRESSES THAT ARE USED ON THE INTERNET ARE CALLED WHAT
PUBLIC ADDRESSES
WHAT IS A (NAT) NETWORK ADDRESS TRANSLATION
RUNS ON THE ROUTER AND HANDLES THE TRANSLATION OF PRIVATE, NONROUTABLE IP ADDRESSES INTO PUBLIC IP ADDRESSES
PAGE 316
WHAT ARE THE RANGES OF PRIVATE IP ADDRESS RANGE
10.0.0.0.-10.255.255.255.255 DEFAULT 255.0.0.
HOST 16.7 MILLION
- 16.0.0-172.31.255.255 DEFAULT 255.240.0.0 HOST 1 MILLION
- 168.0.0-192.168.255.255 DEFAULT 255.255.0.0 HOST 65,536
PAGE 316
CAN A PRIVATE ADDRESSES BE USED ON THE INTERNET
NO IT CANNOT BE USED ON THE INTERNET AND CANNOT BE
WHAT IS NAT
IS ACTUALLY A ONE-TO-ONE PRIVATE-TO-PUBLIC IP ADDRESS TRANSLATION PROTOCOL
PAGE 318
WHAT IS A NAT OVERLOAD
ASLO KNOWN AS PORT ADDRESS TRANSLATION (PAT), WHICH ALLOWS FOR MANY PRIVATE IP ADDRESSES TO USE ONE PUBLIC IP ADDRESS ON THE INTERNET
PAGE 318
WHAT IS AUTOMATCI PRIVATE IP ADDRESSING
KNOWN AS APIPA IS A TCP/IP STANDARD USED TO AUTOMATICALLY CONFIGURE IP-BASED HOST THT ARE UNABLE TO REACH A DHCP SERVER
ARE IN THE 225.255.0.0
