What is the alternative notation for the IPv6 address B514:82C3:0000:0000:0029:EC7A:0000:EC72?
AB514 : 82C3 : 0029 : EC7A : EC72
BB514 : 82C3 :: 0029 : EC7A : EC72
CB514 : 82C3 : 0029 :: EC7A : 0000 : EC72
DB514 : 82C3 :: 0029 : EC7A : 0 : EC72
Correct Answer:D
There are two ways that an IPv6 address can be additionally compressed: compressing leading zeros and substituting a group of consecutive zeros with a single double colon(::). Both of these can be used in any number of combinations to notate the same address. It is important to note that the double colon (::) can only be used once within a single IPv6 address notation. So, the extra 0’s can only be compressed once.

Which IPv6 address is valid?
A2001:0db8:0000:130F:0000:0000:08GC:140B
B2001:0db8:0:130H::87C:140B
C2031::130F::9C0:876A:130B
D2031:0:130F::9C0:876A:130B
Correct Answer:D
An IPv6 address is represented as eight groups of four hexadecimal digits, each group representing 16 bits (two octets). The groups are separated by colons (:). An example of an IPv6 address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334. The leading O’s in a group can be collapsed using ::, but this can only be done once in an IP address.

Bbroadcast

Dpodcast
Eallcast
Correct Answer:AC
IPv6 addresses are classified by the primary addressing and routing methodologies common in networking: unicast addressing, anycast addressing, and multicast addressing. A unicast address identifies a single network interface. The Internet Protocol delivers packets sent to a unicast address to that specific interface. An anycast address is assigned to a group of interfaces, usually belonging to different nodes. A packet sent to an anycast address is delivered to just one of the member interfaces, typically the nearest host, according to the routing protocol’s definition of distance. Anycast ad

Which command enables IPv6 forwarding on a Cisco router?
Aipv6 local
Bipv6 host
Cipv6 unicast-routing
Dipv6 neighbor
Correct Answer:C
To enable IPv6 routing on the Cisco router use the following command: ipv6 unicast-routing If this command is not recognized, your version of IOS does not support IPv6.

Which IPv6 address is the equivalent of the IPv4 interface loopback address 127.0.0.1?
A: :1
B::
C2000::/3
D0::/10
Correct Answer:A
In IPv6 the loopback address is written as, ::1 This is a 128bit number, with the first 127 bits being ‘0’ and the 128th bit being ‘1’. It’s just a single address, so could also be written as ::1/128. QUESTION 104 In which two formats can the IPv6 address fd15:0db8:0000:0000:0700:0003:400F:572B be written? (Choose two.)

Refer to the exhibit. Which two statements are true about the loopback address that is configured on RouterB? (Choose two.) A. It ensures that data will be forwarded by RouterB.
Choose 2 — select all that apply
BIt provides stability for the OSPF process on RouterB.
CIt specifies that the router ID for RouterB should be 10.0.0.1.
DIt decreases the metric for routes that are advertised from RouterB.
EIt indicates that RouterB should be elected the DR for the LAN.
Correct Answer:BC
A loopback interface never comes down even if the link is broken so it provides stability for the OSPF process (for example we use that loopback interface as the router-id) – The router-ID is chosen in the order below: + The highest IP address assigned to a loopback (logical) interface. + If a loopback interface is not defined, the highest IP address of all active router’s physical interfaces will be chosen. -> The loopback interface will be chosen as the router ID of RouterB ?
