IPv4. If this is something that is possible within the organizational network, it is very easy to implement.However, for many organizations, IPv6 is not supported on all of the IPv4 devices; in these situations othermethods must be considered.QUESTION 25Which two statements describe characteristics of IPv6 unicast addressing? (Choose two.)A.Global addresses start with 2000::/3.B.Link-local addresses start with FE00:/12.C.Link-local addresses start with FF00::/10.D.There is only one loopback address and it is ::1.E.If a global address is assigned to an interface, then that is the only allowable address for the interface.Correct Answer:ADSection: IP Addressing
ExplanationExplanation/Reference:IPv6 has three types of addresses, which can be categorized by type and scope:Unicast addresses.A packet is delivered to one interface.- Lots of examplesLink-local.The scope is the local link (nodes on the same subnet).FE80Global.The scope is global (IPv6 Internet addresses).2000 or 3000Site-local.The scope is the organization (private site addressing).-DEPRECATED6to4 Addresses -used for certain types of TunnelsMulticast addresses.A packet is delivered to multiple interfaces. FFxxAnycast addresses.A packet is delivered to the nearest of multiple interfaces (in terms of routing distance).IPv6 does not use broadcast messages.Unicast and anycast addresses in IPv6 have the following scopes (for multicast addresses, the scope is builtinto the address structure):QUESTION 26Which IP addresses are valid for hosts belonging to the 10.1.160.0/20 subnet? (Choose three.)
F.10.1.175.255Correct Answer:ACDSection: IP AddressingExplanationExplanation/Reference:What is the mask for a /20?/16 = 255.255.0.0+4= /20 = 255.255.240.0(use the line for 4 bits)Block size of 16.Starting from 10.1.0.0 count by 16 in the 3rd octet10.1.0.010.1.16.010.1.32.0......10.1.160.0(Can multiply block by 10 to get here faster)10.1.176.0Since 10.1.176 is next network, the broadcast is 10.1.175.25510.1.160.1 - 10.1.175.254 are all valid IPs in the networkQUESTION 27Given an IP address of 192.168.1.42 255.255.255.248, what is the subnet address?CSection: IP Addressing
ExplanationExplanation/Reference:
248 is 5 bits5 bits in the 4th octet is 24+5= 29Network addresses are192.168.1.0192.168.1.8192.168.1.16192.168.1.24192.168.1.32192.168.1.40Address is 192.168.1.42-192.168.1.48QUESTION 28Refer to the exhibit.The enterprise has decided to use the network address 172.16.0.0. The networkadministrator needs to design a classful addressing scheme to accommodate the three subnets, with 30, 40and 50 hosts, as shown. What subnet mask would accommodate this network?ASection: IP Addressing
ExplanationExplanation/Reference:Since it must be classful, each subnet uses the same subnet mask. Choosing the highest host count of 50,which subnet mask would support that many hosts?
