Maximum cable segment length between 220 and 550 meters, Multimode fiber-optic cabling
What are the characteristic features of the 100BASE-FX Ethernet standard?
Maximum cable segment length of up to 412 meters (half-duplex communication), Multimode fiber, Maximum cable segment length of up to 2 kilometers (full-duplex communication)
Which of the answers listed below refer to the 1000BASE-LX Ethernet standard?
Maximum cable segment length of up to 5 kilometers over single-mode fiber, Fiber-optic cabling, Maximum cable segment length of up to 550 meters over multimode fiber
A type of network traffic intended for a particular group of hosts is called:
Multicast
Which of the following solutions alleviates the problem of the depleting IPv4 address space by allowing multiple hosts on the same private LAN to share a single public IP address?
NAT
Which of the solutions listed below hides the internal IP addresses by modifying IP address information in IP packet headers while in transit across a traffic routing device?
NAT
A double colon in an IPv6 address indicates that part of the address containing only zeros has been compressed to make the address shorter. (T or F)
True
Automatic Private IP Addressing (APIPA) allows a Windows host to self-configure an IPv4 address and subnet mask when Dynamic Host Configuration Protocol (DHCP) is unavailable. APIPA uses an address block range between 169.254.0.0 and 169.254.255.255. APIPA-assigned addresses are valid only for communications within a network segment that a given host is connected to (a host with APIPA-assigned address cannot connect to the Internet). (T or F)
True
A type of network traffic intended for a single host identified by a unique IP address is referred to as:
Unicast
Which of the following answers refer to the 100BASE-SX standard?
Uses LED as the source of light, Multimode fiber, Maximum cable segment length of up to 300 meters
Which of the following answers refer to the 10GBASE-SR Ethernet standard?
Uses laser as the source of light, Multimode fiber, Maximum cable segment length of up to 400 meters
What are the characteristic features of the 10GBASE-LR Ethernet standard?
Uses laser as the source of light, Single-mode fiber, Maximum cable segment length of up to 10 kilometers
IPv6 addresses are expressed with the use of:
Hexadecimal numbers
Which of the following answers refers to a method that binds a combination of private IP address and port number with a corresponding public IP address and port information?
PAT
Which of the following documents describes the concept of private IP addressing?
RFC 1918
IPv4 addresses are expressed with the use of:
Decimal numbers
