chapter 7 quiz

The last host address on the 10.15.25.0/24 network is

.254 Refer to curriculum topic: 8.1.3 The host portion of the last host address will contain all 1 bits with a 0 bit for the lowest order or rightmost bit. This address is always one less than the broadcast address. The range of addresses for the network 10.15.25.0/24 is 10.15.25.0 (network address) through 10.15.25.255 (broadcast address). So the last host address for this network is 10.15.25.254.

What is the prefix length notation for the subnet mask 255.255.255.224?

/27 Refer to curriculum topic: 7.1.2 The binary format for 255.255.255.224 is 11111111.11111111.11111111.11100000. The prefix length is the number of consecutive 1s in the subnet mask. Therefore, the prefix length is /27.

The 8-digit binary value of the last octet of the IPv4 address 172.17.10.7 is

00000111 Refer to curriculum topic: 7.1.1 7 = 4 + 2 + 1 = 00000111

The network portion of the address 172.16.30.5/16 is

172.16

The shortest compressed format of the IPv6 address 2001:0DB8:0000:1470:0000:0000:0000:0200 is

2001:DB8:0:1470::200 A double colon (::) can replace any single, contiguous string of one or more 16-bit segments (hextets) consisting of all 0s, and can only be used once per IPv6 address. Any leading 0s (zeros) in any 16-bit section or hextet can be omitted.

an IPV4 link-local address would read as ???

Link-Local addresses are assigned automatically by the OS and are located in the block 169.254.0.0/16. think 69 happen locally

a loopback address would read as ?

Loopback addresses belong to the block 127.0.0.0/8.

In which alternative to DHCPv6 does a router dynamically provide IPv6 configuration information to hosts?

SLAAC

an experimental address would read as ???

The addresses in the block 240.0.0.0 to 255.255.255.254 are reserved as experimental addresses

An IPv6 enabled device sends a data packet with the destination address of FF02::1. What is the target of this packet?​

all IPv6 enabled devices on the local link​ or network Refer to curriculum topic: 7.2.5 This address is one of the assigned IPv6 multicast addresses. Packets addressed to FF02::1 are for all IPv6 enabled devices on the link or network. FF02::2 is for all IPv6 routers that exist on the network.

The IPV6 address FF02::1is know as what type of IPV6 address type?

all node multicast

This network portion of the address is assigned by the provider. Match the description to the IPv6 addressing component.

global routing prefix

The IPV6 address 2001:DB8::BAF:3F57:FE94 is what type of IPV6 address type?

global unicast

This IPV6 part of the address is the equivalent to the host portion of an IPv4 address. Match the description to the IPv6 addressing component.

interface ID

Which type of IPv6 address is not routable and used only for communication on a single subnet?

link-local address IPv6 link-local addresses are in the FE80::/10 range. Refer to curriculum topic: 7.2.3 Link-local addresses have relevance only on the local link. Routers will not forward packets that include a link-local address as either the source or destination address.

The IPV6 address ::1 is know as what type of IPV6 address type?

loopback

FF02::1:FFAE:F85F is known as what type of IPV6 address type?

solicited node multicast

This part of the address is used by an organization to identify subnets. Match the description to the IPv6 addressing component.

subnet ID

A user who is unable to connect to the file server contacts the help desk. The helpdesk technician asks the user to ping the IP address of the default gateway that is configured on the workstation. What is the purpose for this ping command?

to test that the host has the capability to reach hosts on other networks Refer to curriculum topic: 7.3.2 The ping command is used to test connectivity between hosts. The other options describe tasks not performed by ping. Pinging the default gateway will test whether the host has the capability to reach hosts on its own network and on other networks.

Which network migration technique encapsulates IPv6 packets inside IPv4 packets to carry them over IPv4 network infrastructures?

tunneling

Which two types of devices are typically assigned static IP addresses?

web server and printers Servers and peripherals are often accessed by an IP address, so these devices need predictable IP addresses. End-user devices often have dynamic addresses that are assigned. Hubs do not require IPv4 addresses to operate as intermediary devices.
