Question 61 (1 point) No matter how it's configured, a single switch port is considered what? A separate multicast domain A separate collision domain A separate unicast domain A separate broadcast domain Question 62 (1 point) Switches create multiple O Collision domains O Networks O Broadcast Domains WANS Question 63 (1 point) What is the function of the Physical Layer Protocol Olt includes the user 1/0 devices such as keyboard and monitor. It is responsible for the transmission of bits on the physical medium. It performs formatting of data to the user. It manages the network device to network device link connection. It opens closes and manages sessions, Question 64 (1 point) Which protocol implements ping request and replies? Echo Request/Echo Reply Client/Server O ICMP Question 66 (1 point) What is a LAN? Line Area Network O Location Area Network Local Area Network Local Area Networking Question 67 (1 point) Why do network devices need two layers of addressing, Data Link Layer Address (.e. Ethernet) and a Network Layer Address (ie. IP Address)? Since MAC addresses are unique, a Data Link Layer Addresses can be used to forward frames to any destination. A Network Layer Address is logical an can only be used to send data to a destination on the same network segment. O A Data Link Layer Address is used to forward the packet from one network segment to another network segment. The Network Layer Address is used to forward the frame from one device to another within the network segment. O A Network Layer Address is used to forward the packet from one network segment to another network segment. The Data Link Address is used to forward the frame from one device to another within the network segment. The IP Address can be used to forward packets to the final destination but historically Ethernet was developed first so it continues to be used for Data Link Addressing. Question 68 (1 point) The four major LAN computer network topologies are: O , cab, ring, peer-to-peer, and star. O Microsoft, Novell, Linux, and Unix O bus, point-to-point, star, and hybrid. O , bus, star, token ring, and hybrid. peer-to-peer, point-to-point, hub, and hybrid. Question 69 (2 points) Which two statements about Layer 2 Ethernet switches are true? (select two) A) Layer 2 switches prevent broadcasts. B) Layer 2 switches can send traffic based on the destination MAC address, OC) Layer 2 switches have multiple collision domains. D) Layer 2 switches decrease the number of broadcast domains. E) Layer 2 switches route traffic between different networks. Question 70 (1 point) In the TCPAP protocol suite, the application layer is roughly equivalent to which layers of the OSI model? 1. Application II. Presentation III Session IV. Transport V Network Ol Tonly 1. I and IV O II and III 01. I and III I and
