The prefix-length for the range of addresses is
All the addresses have the part 2001:0DB8:BC15:00A in common. Each number or letter in the address represents 4 bits, so the prefix-length is /60.
60

the site administrator has been told that a particular network at the site must accommodate 126 hosts. Which subnet mask would be used that contains the required number of host bits?
is this still up to date?
Yes
hi guys, does this test contain a part where we need to do something in packet tracer? Thx
question 49
Are these still up to date? i just started this class and have failed the first three test but this will help if they’re up to date, thank you
Yes, it still valid
I know I just started this too and I never realized they have these on here until a friend showed it
New question:
Which of these addresses is the shortest abbreviation for the IP address:

14. Refer to the exhibit. Considering the addresses already used and having to remain within the 10.16.10.0/24 network range, which subnet address could be assigned to the network containing 25 hosts?
Explanation: Addresses 10.16.10.0 through 10.16.10.63 are taken for the leftmost network. Addresses 10.16.10.192 through 10.16.10.207 are used by the center network.The address space from 208-255 assumes a /28 mask, which does not allow enough host bits to accommodate 25 host addresses.The address ranges that are available include 10.16.10.64/26 and10.16.10.128/26. To accommodate 25 hosts, 5 host bits are needed, so a /27 mask is necessary. Four possible /27 subnets could be created from the available addresses between 10.16.10.64 and 10.16.10.191:
10.16.10.64/27
10.16.10.96/27
10.16.10.128/27
10.16.10.160/27
How to calculate the range of available addresses with /27 subnets ??
Group-Size = number hosts needed (-2)
/27 [.224] [00011111] typically has a group-size of 32 THUS: 32 -2 = 30
128 group size = 128 – 10000000 (126 hosts available) /25
192 group size = 64 – 11000000 ( 62 hosts available) /26
224 group size = 32 – 11100000 ( 30 hosts available) /27 <== 30 (25 needed)
240 group size = 16 – 11110000 ( 14 hosts available) /28
248 group size = 8 – 11111000 ( 6 hosts available) /29
252 group size = 4 – 11111100 ( 2 hosts available) /30
254 group size = 2 – 11111110 ( 1 host available) /31
255 group size = 1 – 11111111 ( 0 hosts available) /32
= LOGIC – no calculating required
I need 120 hosts. Don’t think. Look for 128.
I need 50 hosts. Don’t think. Look for 64
Picture above: .0 and .192 are taken
Picture above: /26 & /28 are taken
= The in-between is missing
Finally 128 is 1000000 (meaning 1 & 0 = two networks available.) 128/2=64
is there a final for module 11- 17?
No, only final https://itexamanswers.net/ccna-1-v7-0-final-exam-answers-full-introduction-to-networks.html
Are they all correct? Has anyone tried them?
Yes they are

Refer to the exhibit. A company is deploying an IPv6 addressing scheme for its network. The company design document indicates that the subnet portion of the IPv6 addresses is used for the new hierarchical network design, with the s ite subsection to represent multiple geographical sites of the company, the s ub-site section to represent multiple campuses at each site, and the s ubnet section to indicate each network segment separated by routers. With such a scheme, what is the maximum number of subnets achieved per sub-site ?
0
4
16
256
one choice
16
Because only one hexadecimal character is used to represent the subnet, that one character can represent 16 different values 0 through F
correct. I did the test and got this question right by putting 16.
I think 16
16
Is the spaces between s and the rest of the letters typos?
16 Is Correct answer

A user issues a ping fe80:65ab:dcc1::100 command and receives a response that includes a code of 3 . What does this code represent?
communication with the destination administratively prohibited
no route to destination
beyond scope of the source address
Some of the Destination Unreachable codes for ICMPv6 are as follows:
0 – No route to destination
1 – Communication with the destination is administratively prohibited (e.g., firewall)
2 – Beyond scope of the source address
3 – Address unreachable
4 – Port unreachable

23. Which of these addresses is the shortest abbreviation for the IP address:
3FFE:1044:0000:0000:00AB:0000:0000:0057?
Why 1st option is not correct??
yes why 1st is not correct?
I’m pretty sure you can only use the double colon once per address?
Correct
because, only zeroes are deleted, and you need three sets of zeroes in a row to use double colon.

Qual sub-rede incluiria o endereço 192.168.1.96 como um endereço de host utilizável?
Sorry, my exam is in Portuguese!
192.168.1.64/26
Para a sub-rede de 192.168.1.64/26, existem 6 bits para endereços de host, resultando em 64 endereços possíveis. No entanto, a primeira e a última sub-rede são os endereços de rede e de broadcast dessa sub-rede. Portanto, o intervalo de endereços de host para esta sub-rede é 192.168.1.65 a 192.168.1.126. As outras sub-redes não contêm o endereço 192.168.1.96 como um endereço de host válido.

With such a scheme, what is the maximum number of subnets achieved per sub-site ?
answer is 16
this tripped me out but spent a while trying to get my head around it.
Question is sneaky and asking what is the maximum number of SUBNET’s achieved PER sub-site ?
Question asking how many subnets can you have per sub-site. if you see in the picture the Subnet portion is only 1 bit, so there is only 16 possible subnets. (Hex 0 – F)
hope this makes sense.
