Explain:An IPv4 address is comprised of 4 octets that binary digits, each containing 8 bits, leading to a 32-bit address.
Which two components are materials of one IPv4 address? (Choose two.)subnet portionnetwork portion*logical portionhost portion*physical portionbroadcast portion
What walk the IP resolve 172.17.4.250/24 represent?network addressmulticast addresshost address*broadcast address
Explain:An IPv4 resolve is divided into two parts: a network part – to identify the details network on which a organize resides, and a host portion – to identify details hosts ~ above a network. A subnet mask is used to identify the size of every portion.
What is the objective of the subnet mask in conjunction through an IP address?to uniquely identify a organize on a networkto identify whether the address is public or privateto recognize the subnet to which the organize belongs*to mask the IP resolve to outsiders
Explain:The /24 shows that the network resolve is 172.17.4.0. The broadcast deal with for this network would be 172.17.4.255. Useable organize addresses for this network room 172.17.4.1 through 172.17.4.254.
What subnet mask is represented by the slash notation /20?255.255.255.248255.255.224.025188.8.131.52*255.255.255.025184.108.40.206
Explain:With the IPv4 address, a subnet mask is also necessary. A subnet mask is a special kind of IPv4 attend to that coupled v the IP resolve determines the subnet of i beg your pardon the maker is a member.
A post is sent to all hosts ~ above a remote network. Which kind of article is it?limited broadcastmulticastdirected broadcast*unicast
Explain:The slash notation /20 to represent a subnet mask through 20 1s. This would analyze to: 11111111.11111111.11110000.0000, which in turn would convert into 255.255.240.0.
What space three attributes of multicast transmission? (Choose three.)The source address that a multicast infection is in the range of 220.127.116.11 come 18.104.22.168.A single packet can be sent out to a team of hosts. *Multicast transmission have the right to be used by routers come exchange routing information. *The variety of 22.214.171.124 come 126.96.36.199 is scheduled to with multicast groups on a regional network.*Computers usage multicast infection to inquiry IPv4 addresses.Multicast messages map reduced layer addresses to top layer addresses.
Explain:A directed broadcast is a post sent to every hosts ~ above a particular network. It is helpful for sending a transfer to every hosts on a nonlocal network. A multicast blog post is a message sent come a selected group of hosts that are component of a subscribing multicast group. A minimal broadcast is used for a communication that is minimal to the hosts on the neighborhood network. A unicast message is a article sent native one organize to another.
Which 3 IP addresses are personal ? (Choose three.)10.1.1.1*188.8.131.52184.108.40.206220.127.116.11 *192.168.5.5*18.104.22.168
Explain:Broadcast message consist of single packets the are sent out to every hosts ~ above a network segment. These varieties of message are used to request IPv4 addresses, and also map upper layer addresses to lower layer addresses. A multicast infection is a single packet sent to a team of hosts and also is offered by routing protocols, such as OSPF and RIPv2, come exchange routes. The address variety 22.214.171.124 to 126.96.36.199 is scheduled for link-local addresses to reach multicast groups on a regional network.
Which 2 IPv4 come IPv6 shift techniques control the interconnection that IPv6 domains? (Choose two.)trunkingdual stack*encapsulationtunneling*multiplexing
Explain:The private IP addresses space within these three ranges:10.0.0.0 – 10.255.255.255172.16.0.0 – 172.31.255.255192.168.0.0 – 192.168.255.255
Which of this addresses is the shortest abbreviation for the IP address:3FFE:1044:0000:0000:00AB:0000:0000:0057?3FFE:1044::AB::573FFE:1044::00AB::00573FFE:1044:0:0:AB::57*3FFE:1044:0:0:00AB::00573FFE:1044:0000:0000:00AB::573FFE:1044:0000:0000:00AB::0057What form of deal with is instantly assigned to an user interface when IPv6 is enabled on the interface?global unicastlink-local*loopbackunique local
Explain:There room three approaches to enable IPv4 and IPv6 come co-exist ~ above a network. Double stack allows IPv4 and IPv6 come coexist top top the very same network segment. Dual stack tools run both IPv4 and IPv6 protocol stacks simultaneously. Tunneling is a technique of delivering an IPv6 packet end an IPv4 network. The IPv6 packet is encapsulated within an IPv4 packet, comparable to other varieties of data. Network deal with Translation 64 (NAT64) permits IPv6-enabled devices to connect with IPv4-enabled devices using a translation technique similar to NAT for IPv4
What room two species of IPv6 unicast addresses? (Choose two.)multicastloopback*link-local*anycastbroadcast
Explain:When IPv6 is allowed on any type of interface, that interface will immediately generate one IPv6 link-local address.
What space three parts of an IPv6 worldwide unicast address? (Choose three.)an user interface ID the is offered to determine the local network because that a certain hosta worldwide routing prefix the is used to identify the network portion of the address that has actually been listed by an ISP *a subnet ID the is offered to identify networks within of the local enterprise site*a an international routing prefix that is used to determine the portion of the network address provided by a neighborhood administratoran user interface ID the is supplied to identify the local organize on the network*
Explain:Multicast, anycast, and also unicast are varieties of IPv6 addresses. There is no broadcast resolve in IPv6. Loopback and also link-local room specific types of unicast addresses.
An administrator desires to configure master to immediately assign IPv6 addresses to themselves by the usage of Router advertisement messages, but additionally to obtain the DNS server address from a DHCPv6 server. Which address assignment an approach should it is in configured?SLAACstateless DHCPv6*stateful DHCPv6RA and EUI-64
Explain:There space three aspects that comprise an IPv6 global unicast address. A worldwide routing prefix which is provided by an ISP, a subnet ID which is figured out by the organization, and also an interface ID which unique identifies the interface interface the a host.
Which protocol supports Stateless resolve Autoconfiguration (SLAAC) because that dynamic assignment the IPv6 addresses to a host?ARPv6DHCPv6ICMPv6*UDP
Explain:Stateless DHCPv6 enables clients to use ICMPv6 Router advertisement (RA) messages to automatically assign IPv6 addresses come themselves, however then permits these clients to call a DHCPv6 server come obtain extr information such together the domain surname and resolve of DNS servers. SLAAC does not enable the customer to obtain added information v DHCPv6, and stateful DHCPv6 calls for that the customer receive that is interface attend to directly indigenous a DHCPv6 server. RA messages, when combined with one EUI-64 user interface identifier, are offered to immediately create an interface IPv6 address, and are part of both SLAAC and also stateless DHCPv6.
Which two things deserve to be established by making use of the ping command? (Choose two.)the number of routers between the resource and destination devicethe IP resolve of the router nearest the location devicethe mean time that takes a packet to with the destination and also for the solution to return to the resource *the destination device is reachable through the network*the median time it takes every router in the route between resource and destination to respond
Explain:SLAAC offers ICMPv6 messages when dynamically assigning an IPv6 deal with to a host. DHCPv6 is an alternate technique of assigning one IPv6 addresses come a host. ARPv6 does not exist. Neighbor exploration Protocol (NDP) gives the functionality of ARP for IPv6 networks. UDP is the deliver layer protocol provided by DHCPv6.
What is the purpose of ICMP messages?to notify routers about network topology changesto ensure the shipment of one IP packetto carry out feedback of IP packet transmissions*to monitor the procedure of a domain name to IP deal with resolution
Explain:A ping command provides feedback ~ above the time between when an echo request was sent out to a far host and also when the echo answer was received. This have the right to be a measure of network performance. A successful ping additionally indicates the the destination host to be reachable v the network.
What is indicated by a effective ping come the ::1 IPv6 address?The organize is cabled properly.The default gateway address is effectively configured.All master on the local connect are available.The link-local attend to is correctly configured.IP is properly mounted on the host.*
Explain:The objective of ICMP message is to administer feedback about issues the are concerned the processing of IP packets.
A user is executing a tracert to a remote device. At what suggest would a router, i m sorry is in the course to the destination device, protect against forwarding the packet?when the router receives an ICMP Time surpassed messagewhen the RTT worth reaches zerowhen the host responds through an ICMP Echo answer messagewhen the value in the TTL ar reaches zero*when the worths of both the Echo Request and also Echo answer messages with zero
Explain:The IPv6 resolve ::1 is the loopback address. A successful ping come this address method that the TCP/IP ridge is appropriately installed. It does not typical that any addresses are appropriately configured.
What is the binary identical of the decimal number 232?11101000*110001101001100011110010What is the decimal tantamount of the binary number 10010101?149157168192What field content is used by ICMPv6 to determine that a packet has actually expired?TTL fieldCRC fieldHop border field*Time surpassed field
Explain:When a router obtain a traceroute packet, the worth in the TTL field is decremented by 1. When the value in the ar reaches zero, the receiving router will certainly not forward the packet, and will send an ICMP Time gone beyond message earlier to the source.
Fill in the blank.The decimal identical of the binary number 10010101 is 149
Explain:ICMPv6 sends a Time Exceeded blog post if the router can not forward an IPv6 packet since the packet expired. The router uses a hop limit ar to identify if the packet has actually expired, and also does not have actually a TTL field.
Explain:To transform a binary number come the decimal equivalent, add the value of the position where any type of binary 1 is present.
Fill in the blank.The binary identical of the decimal number 232 is 11101000
Explain:To transform a decimal number come binary, very first determine if the decimal number is equal to or better than 128. In this case, since 232 is bigger than 128, a 1 is put in the little position because that decimal value 128 and the value of 128 is then subtracted native 232. This results in the value of 104. Us then to compare this worth to 64. As 104 is larger than 64, a 1 is placed in the bit position because that the decimal value 64 and also the value of 64 is subtracted from 104. The continuing to be value is then 40. The process should be continued for every the remaining little positions.
Fill in the blank.What is the decimal equivalent of the hex number 0x3F? 63
Explain:To convert from hexadecimal to decimal, multiply every digit through the place value that is connected with the place of the number and include the results.
