Exam # 8

TTL

A field in an IP datagram that specifies how many more hops a packet can travel before being discarded is called:

Multicast

A type of network traffic intended for a particular group of hosts is known as:

Unicast

A type of network traffic intended for a single host identified by a unique IP address is commonly referred to as:

IP To MAC

Address Resolution Protocol (ARP) provides what kind of resolution?

True

Network Address Translation (NAT) provides an IP proxy between a private LAN and a public network such as the Internet.

CSMA

Which of the answers listed below refers to a network protocol providing means for controlling access to a transmission medium?

CSMA/CA

Which of the following allows for controlling the shared medium in order to minimize collisions in 802.11 networks?

PAT

Which of the following answers refers to a Network Address Translation (NAT) method that binds a combination of private IP address and port number with a corresponding public IP address and port information?

- Maximum hop count - Time to live (TTL)

Which of the following mechanisms can be used to prevent routing loops? (Select 2 answers)

Smurf attack

Which of the following network attack types exploits broadcast traffic?

NAT

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?

CSMA/CD

Which of the following solutions allows for verifying the absence of other traffic on a shared medium before transmitting in order to prevent collisions and loss of data in 802.3 networks?

NAT

Which of the following solutions hides the internal IP addresses by modifying IP address information in IP packet headers while in transit across a traffic routing device?

Broadcast

Which of the following transmission types would be used to reach a networked host with unknown address?
