You are watching: What are three characteristics of multicast transmission? (choose three.)
NOTE: If you have actually the brand-new question ~ above this test, please comment Question and Multiple-Choice perform in kind below this article. We will upgrade answers for you in the shortest time. Give thanks to you! us truly worth your donation to the website.
Explain:An IPv4 deal with is consisted of of 4 octets that binary digits, every containing 8 bits, resulting in a 32-bit address.
Explain:An IPv4 attend to is split into 2 parts: a network part – to identify the details network on which a hold resides, and a host part – come identify certain hosts top top a network. A subnet mask is supplied to identify the size of each portion.
Explain:The /24 shows that the network address is 172.17.4.0. The broadcast address for this network would certainly be 172.17.4.255. Useable hold addresses for this network are 172.17.4.1 v 172.17.4.254.
to uniquely identify a hold on a networkto recognize whether the resolve is publicly or privateto recognize the subnet come which the organize belongs*to mask the IP resolve to outsiders
Explain:With the IPv4 address, a subnet mask is likewise necessary. A subnet mask is a special form of IPv4 resolve that coupled v the IP deal with determines the subnet of which the maker is a member.
Explain:The slash notation /20 represents a subnet mask with 20 1s. This would translate to: 11111111.11111111.11110000.0000, which consequently would convert into 255.255.240.0.
Explain:A directed transfer is a message sent to every hosts top top a details network. The is beneficial for sending out a transfer to all hosts ~ above a nonlocal network. A multicast post is a post sent come a selected group of hosts that are part of a subscribing multicast group. A restricted broadcast is provided for a interaction that is limited to the master on the neighborhood network. A unicast article is a blog post sent from one hold to another.
The source address of a multicast transmission is in the selection of 220.127.116.11 to 18.104.22.168.A solitary packet can be sent out to a team of hosts. *Multicast transmission can be supplied by routers come exchange routing information. *The variety of 22.214.171.124 to 126.96.36.199 is scheduled to with multicast teams on a local network.*Computers use multicast transmission to inquiry IPv4 addresses.Multicast messages map reduced layer addresses to upper layer addresses.
Explain:Broadcast message consist of solitary packets that are sent to every hosts ~ above a network segment. These varieties of messages are supplied to inquiry IPv4 addresses, and map top layer addresses to lower layer addresses. A multicast transmission is a single packet sent out to a group of hosts and is used by routing protocols, such together OSPF and also RIPv2, to exchange routes. The address variety 188.8.131.52 to 184.108.40.206 is reserved for link-local addresses to with multicast groups on a regional network.
Explain:The personal IP addresses room within these 3 ranges:10.0.0.0 – 10.255.255.255172.16.0.0 – 172.31.255.255192.168.0.0 – 192.168.255.255
9. Which two IPv4 come IPv6 change techniques regulate the interconnection the IPv6 domains? (Choose two.)
Explain:There space three methods to enable IPv4 and also IPv6 come co-exist on a network. Double stack allows IPv4 and IPv6 come coexist ~ above the exact same network segment. Dual stack gadgets run both IPv4 and also IPv6 protocol stacks simultaneously. Tunneling is a method of transferring an IPv6 packet over an IPv4 network. The IPv6 packet is encapsulated within an IPv4 packet, comparable to other varieties of data. Network address Translation 64 (NAT64) allows IPv6-enabled gadgets to communicate with IPv4-enabled tools using a translation technique similar to NAT because that IPv4
10. I beg your pardon of these addresses is the shortest abbreviation because that the IP address:3FFE:1044:0000:0000:00AB:0000:0000:0057?
11. What kind of attend to is instantly assigned to an user interface when IPv6 is enabled on the interface?
Explain:When IPv6 is permitted on any type of interface, that interface will instantly generate one IPv6 link-local address.
Explain:Multicast, anycast, and unicast are varieties of IPv6 addresses. Over there is no broadcast deal with in IPv6. Loopback and also link-local room specific species of unicast addresses.
an interface ID the is used to recognize the regional network for a details hosta global routing prefix that is used to identify the network portion of the attend to that has actually been noted by one ISP *a subnet ID the is used to determine networks inside of the regional enterprise site*a global routing prefix that is provided to recognize the portion of the network address provided by a regional administratoran interface ID the is supplied to determine the local organize on the network*
Explain:There space three facets that comprise an IPv6 worldwide unicast address. A worldwide routing prefix i m sorry is listed by an ISP, a subnet ID i m sorry is determined by the organization, and an user interface ID which uniquely identifies the user interface interface the a host.
14. An administrator wants to configure hosts to instantly assign IPv6 addresses to themselves by the use of Router advertising messages, but likewise to attain the DNS server deal with from a DHCPv6 server. Which deal with assignment an approach should it is in configured?
Explain:Stateless DHCPv6 enables clients to usage ICMPv6 Router advertisement (RA) message to automatically assign IPv6 addresses to themselves, yet then permits these client to call a DHCPv6 server to obtain extr information such together the domain name and deal with of DNS servers. SLAAC walk not enable the client to obtain additional information v DHCPv6, and stateful DHCPv6 requires that the client receive its interface resolve directly indigenous a DHCPv6 server. RA messages, when combined with an EUI-64 user interface identifier, are used to instantly create an interface IPv6 address, and are component of both SLAAC and also stateless DHCPv6.
15. I m sorry protocol support Stateless resolve Autoconfiguration (SLAAC) for dynamic assignment the IPv6 addresses to a host?
Explain:SLAAC uses ICMPv6 messages when dynamically assigning one IPv6 attend to to a host. DHCPv6 is one alternate technique of assigning an IPv6 addresses to a host. ARPv6 does not exist. Neighbor exploration Protocol (NDP) offers the usability of ARP for IPv6 networks. UDP is the transport layer protocol supplied by DHCPv6.
the number of routers in between the resource and location devicethe IP resolve of the router nearest the destination devicethe average time the takes a packet to reach the destination and also for the solution to return to the source *the destination machine is reachable with the network*the average time the takes every router in the path between resource and destination to respond
Explain:A ping command offers feedback on the time between when an echo inquiry was sent out to a far host and also when the echo reply was received. This have the right to be a measure of network performance. A effective ping additionally indicates the the location host was reachable with the network.
to educate routers about network topology changesto certain the shipment of one IP packetto carry out feedback that IP packet transmissions*to monitor the process of a domain surname to IP attend to resolution
Explain:The objective of ICMP message is to carry out feedback about issues the are pertained to the handling of IP packets.
The organize is cabled properly.The default gateway resolve is effectively configured.All hosts on the local link are available.The link-local address is effectively configured.IP is properly installed on the host.*
Explain:The IPv6 attend to ::1 is the loopback address. A effective ping come this address way that the TCP/IP stack is effectively installed. It does not average that any addresses are effectively configured.
19. A user is executing a tracert come a remote device. At what allude would a router, i beg your pardon is in the path to the destination device, protect against forwarding the packet?
when the router receives an ICMP Time exceeded messagewhen the RTT value reaches zerowhen the host responds through an ICMP Echo reply messagewhen the worth in the TTL field reaches zero*when the values of both the Echo Request and also Echo answer messages reach zero
Explain:When a router obtain a traceroute packet, the worth in the TTL field is decremented by 1. When the worth in the field reaches zero, the receiving router will not forward the packet, and also will send one ICMP Time gone beyond message back to the source.
Explain:ICMPv6 sends a Time Exceeded article if the router can not forward an IPv6 packet because the packet expired. The router uses a hop limit field to identify if the packet has expired, and does not have a TTL field.
Explain:To transform a binary number come the decimal equivalent, include the value of the place where any kind of binary 1 is present.
Explain:To convert a decimal number come binary, an initial determine if the decimal number is equal to or better than 128. In this case, since 232 is larger than 128, a 1 is placed in the little position for decimal worth 128 and the worth of 128 is then subtracted indigenous 232. This outcomes in the value of 104. Us then compare this value to 64. Together 104 is bigger than 64, a 1 is put in the bit position because that the decimal value 64 and also the worth of 64 is subtracted indigenous 104. The remaining value is then 40. The process should be continued for all the remaining bit positions.
Explain:To convert from hexadecimal to decimal, multiply each digit by the place value that is linked with the position of the digit and add the results.
