What is a characteristics of multicast?
They are sent to a select group of hosts. They are sent to all hosts on a network. They must be acknowledged. They are sent to a single destination.
Which of the following is a characteristic of multicast transmission?
A multicast transmission is a single packet sent to a group of hosts and is used by routing protocols, such as OSPF and RIPv2, to exchange routes. The address range 224.0. 0.0 to 224.0. 0.255 is reserved for link-local addresses to reach multicast groups on a local network.
What is the characteristics of multicast transmission?
Characteristics of multicasting are as follows: Designed to handle traffic destined to multiple hosts. Multicast traffic establishes a one-to-many type of transmission, sending one stream of traffic to each requesting broadcast domain. The IP address that defines a multicast group is a Class D address (224.0.What is a characteristic of the LLC sublayer?
It provides the logical addressing required that identifies the device. It provides delimitation of data according to the physical signaling requirements of the medium.

What are three private IPv4 address choose three?
The designated private IP addresses are within the three IP address ranges: 10.0. 0.0 – 10.255. 255.255.What are the characteristics of reliable multicast?
Reliable Multicast Goals Validity: If a correct process multicasts (sends) message m, then it will eventually deliver m itself. – Guarantees liveness to the sender. Validity and agreement together ensure overall liveness: if some correct process multicasts a message m, then, all correct processes deliver m too.
What is the structure of an IPv4 address?IPv4 addresses are 32-bit numbers that are typically displayed in dotted decimal notation. A 32-bit address contains two primary parts: the network prefix and the host number. All hosts within a single network share the same network address. Each host also has an address that uniquely identifies it.
Article first time published onWhich choices are characteristic of an IP address choose two?
- does not require a dedicated end-to-end connection.
- operates independently of the network media.
- retransmits packets if errors occur.
- re-assembles out of order packets into the correct order at the receiver end.
- guarantees delivery of packets.
What are two differences between binary and decimal numbers choose two?
Decimal numbers are based on powers of 1. Binary numbers are based on powers of 2. Decimal numbers include 0 through 9. Numbers typed on a keyboard are entered as binary and converted to decimal by the computer.
What are the two components of an IPv4 address?
The bytes of the IPv4 address are further classified into two parts: the network part and the host part. The following figure shows the component parts of a typical IPv4 address, 129.144. 50.56.
What is a characteristic of the LLC sublayer It provides delimitation of data according to the physical signaling requirements of the medium it plac?
It provides delimitation of data according to the physical signaling requirements of the medium. It places information in the frame allowing multiple Layer 3 protocols to use the same network interface and media. It defines software processes that provide services to the physical layer.
Which two functions are performed at the LLC sublayer?
Enables IPv4 and IPv6 to utilize the same network interface and media. Provides data link layer addressing. Implements a trailer to detect transmission errors. Provides synchronization between source and target nodes.
What is the purpose of the layer 2 LLC sublayer?
What is the purpose of the layer 2 LLC sublayer? The LLC sub-layer acts as an interface between the Media Access Control (MAC) sublayer and the network layer.
What is a characteristic of a WAN hub and spoke topology group of answer choices?
What is a characteristic of a WAN hub-and-spoke topology? A hub-and-spoke topology is a WAN version of the star topology in which a central site interconnects branch sites using point-to-point links. A mesh topology requires that every end system be interconnected to every other system using point-to-point links.
What statement describes a characteristic of MAC addresses?
What statement describes a characteristic of MAC addresses? They must be globally unique.
What three items are contained in a Ethernet header and trailer?
The header features destination and source MAC addresses (each six octets in length), the EtherType field and, optionally, an IEEE 802.1Q tag or IEEE 802.1ad tag.
What are Ethernet standard 802.3 and frame formats?
- PREAMBLE – Ethernet frame starts with 7-Bytes Preamble. …
- Start of frame delimiter (SFD) – This is a 1-Byte field which is always set to 10101011. …
- Destination Address – This is 6-Byte field which contains the MAC address of machine for which data is destined.
What are the different cable types defined by IEEE 802.3 standard and where are they used?
This is generally a local area network (LAN) technology with some wide area network (WAN) applications. Physical connections are made between nodes and/or infrastructure devices (hubs, switches, routers) by various types of copper or fiber cable. … 802.3 also defines LAN access method using CSMA/CD.
What is the purpose of the OSI physical layer?
Physical layer is the lowest layer of the OSI reference model. It is responsible for sending bits from one computer to another. This layer is not concerned with the meaning of the bits and deals with the setup of physical connection to the network and with transmission and reception of signals.
What are the properties of reliable multicast in distributed systems?
A reliable multicast protocol allows a group of processes to agree on a set of messages received by the group. Each message should be received by all members of the group or by none. The order of these messages may be important for some applications.
How reliable is multicast?
The Reliable multicast protocol runs over UDP and uses the IP multicast [1] service for packet delivery. Since both IP multicast and UDP are unreliable protocols, the reliability is achieved by running an end to end reliable protocol at the application level.
What is basic multicast?
Basic multicast refers to multicasting at the link layer or below. In the case of Ethernet, any frame where the least significant bit of the first byte of the destination address are sent to all nodes in the network.
Which three devices are considered intermediate devices in a network choose three?
Examples of intermediary network devices are: switches and wireless access points (network access) routers (internetworking) firewalls (security).
Which address prefix range is reserved for IPv4 multicast?
Multicast IPv4 addresses use the reserved class D address range of 224.0. 0.0 to 239.255. 255.255.
Which IP address is a unicast address?
Unicast addresses are what you would call regular addresses. They are the addresses usually bound to your network card. Unicast addresses should be unique on a network, meaning a single unicast address should only represent a single system. Multicast addresses are used to make a one-to-many connection.
How can we distinguish a multicast address in IPv4 addressing?
Routers and switches must have a way to distinguish multicast traffic from the unicast or broadcast traffic. This is done by reserving a dedicated IPv4 Multicast Address Range, 224.0. 0.0 through 239.255. 255.255, strictly for Multicast Traffic and Services, also known as a IPv4 Class D.
What is the purpose of a subnet mask?
A subnet mask is used to divide an IP address into two parts. One part identifies the host (computer), the other part identifies the network to which it belongs.
What is the first field in an IPv6 header?
Source address (128 bits) The 128-bit source address field contains the IPv6 address of the originating node of the packet. It is the address of the originator of the IPv6 packet.
