The second step is installing and configuring the network protocol
9. Which of your following subnet masks are represented with all the CIDR of /20?
A. 255.255.254.0
B. 255.255.255.254
C. 255.255.192.0
D. 255.255.240.0
Answer: D. The CIDR /20 tells you that twenty 1s are turned ccnp exam
on within the subnet mask. Twenty 1s equal 11111111.11111111.11110000.00000000 . This would then equal 255.255.240.0.
ten. With a /28 mask, which of your following addresses could be assigned to hosts on the identical subnet? (Select all that apply.)
A. 192.168.1.0
B. 192.168.1.17
C. 192.168.1.31
D. 192.168.1.16
E. 192.168.1.25
Answer: B, E. Apart from not getting on the identical subnet as the other individuals, when a /28 mask is applied to all 5 addresses, 192.168.1.0 falls on a subnet boundary and cannot be applied for host address assign- ment. In the others, only 192.168.1.7 and 192.168.1.25 are valid host addresses on exactly the same subnet when a /28 mask is applied. Although 192.168.1.16 and 192.169.1.31 are both on exactly the same subnet as the two correct answers, they represent the subnet boundary address along with the sub- net broadcast address, respectively, and are so illegal for use in host address assignment.
11. Which with the following are subnet boundary addresses that outcome from the use on the /29 mask? (Choose all that apply.)
A. 172.20.73.12
B. 10.8.1.212
C. 192.168.0.0
D. 192.168.1.16
E. 192.168.164.208
Answer: C, D, E. Remember, you’re able to at all times use a practice exams
the 0 subnet, creating choice C a valid response. Mainly because 32 C 29 = 3 and 2 3 = 8, the subnet boundaries within the fourth octet (32 could be the next many of 8 larger than 29, and 32 8 = 4) will likely be multiples of 8, generating options D and E valid also.
12. Which on the following are enhancements/changes to World wide web Protocol in version 6? (Select two.)
A. Larger IP address space of 128 bits
B. Expanded TCP and UDP port values 32 bits wide
C. Broadcast messages are enhanced to provide improved ICMP
D. IP mobility functionality allowing a TCP communicating device to hop amongst IP networks and preserve TCP connectivity
E. A variable-length IP header to include things like a checksum verifying the integrity of your IP/TCP/ Application layer information
F. New IPv6 packet kind of simulcast to enable communication to a single device exactly where a number of devices are configured using the similar address
Answer: A, D. B is incorrect since IPv6 does not change layer 4 (TCP/UDP) functionality. C is incorrect for the reason that IPv6 does away using the broadcast functionality altogether. E is incorrect mainly because IPv6 does away together with the checksum header in the packet (layer three) header. F is also incorrect; the functionality described may be the anycast kind.
