network portion and host portion

Which two ICMP messages are used by both IPv4 and IPv6 protocols? (Choose two.)​

route redirection protocol unreachable

When an IPv6 enabled host needs to discover the MAC address of an intended IPv6 destination, which destination address is used by the source host in the NS message?

solicited-node multicast address

What two statements describe characteristics of Layer 3 broadcasts? (Choose two.)

-Routers create broadcast domains -A limited broadcast packet has a destination IP address of 255.255.255.255

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

/27

What are three parts of an IPv6 global unicast address? (Choose three.)

1. a subnet ID that is used to identify networks inside of the local enterprise site 2. an interface ID that is used to identify the local host on the network 3. a global routing prefix that is used to identify the network portion of the address that has been provided by an ISP

Which two things can be determined by using the ping command? (Choose two.)

1. whether or not the destination device is reachable through the network 2. the average time it takes a packet to reach the destination and for the response to return to the source

The decimal equivalent of the binary number 10010101 is

149

A DHCP server is used to assign IP addresses dynamically to the hosts on a network. The address pool is configured with 192.168.10.0/24. There are 3 printers on this network that need to use reserved static IP addresses from the pool. How many IP addresses in the pool are left to be assigned to other hosts?

251

How many bits are in an IPv4 address?

32

Fill in the blank. What is the decimal equivalent of the hex number 0x3F?

63

Which message is displayed on the web server?

Correct configuration!

Which IPv6 address is most compressed for the full FE80:0:0:0:2AA:FF:FE9A:4CA3 address?​

FE80::2AA:FF:FE9A:4CA3

What is indicated by a successful ping to the ::1 IPv6 address?

IP is properly installed on the host.

Which two statements are correct about IPv4 and IPv6 addresses? (Choose two.)

IPv4 addresses are 32 bits in length. IPv6 addresses are represented by hexadecimal numbers.

When a Cisco router is being moved from an IPv4 network to a complete IPv6 environment, which series of commands would correctly enable IPv6 forwarding and interface addressing?

Router# configure terminal Router(config)# interface fastethernet 0/0 Router(config-if)# ipv6 address 2001:db8:bced:1::9/64 Router(config-if)# no shutdown Router(config-if)# exit Router(config)# ipv6 unicast-routing

Match each IPv4 address to the appropriate address category

To determine whether a given IPv4 address is a network, host, or broadcast address, first determine the address space based on the subnet mask. Convert the address and mask to binary values, and AND to determine the network address. To calculate the of the address space, use the number of host bits in the subnet mask as an exponent of 2. The number of valid host addresses in the space is that number minus 2. The network address will have all zeroes in the host portion, and the broadcast address will have all ones. For example, 10.0.50.10/30 yields a network IP address of 10.0.50.8 when the mask is ANDed with the given address. Because there are only 2 host bits in the mask, there are only 2 valid host addresses (4-2). 10.0.50.10 is one of the two valid host IP addresses.

Match each description with an appropriate IP address

a legacy class A address 64.100.3.5 a legacy class B address 128.107.5.1 a legacy class C address 192.31.18.123 a legacy class D address 224.2.6.255 an invalid IPv4 address 198.256.2.6

Match each description with an appropriate IP address

a link local 169.254.1.5 a TEST 192.0.2.123 an experimental 240.2.5.255 a private 172.19.20.5 a loopback 127.0.0.1

Match each description with an appropriate IP address. (Not all options are used.)

a private address, 64.102.90.23: a loop-back address 127.0.0.1: an experimental address, 240.2.6.255: a TEST-NET address, 192.0.2.123: a link-local address, 169.254.1.5

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 nodes on the local link

A message is sent to all hosts on a remote network. Which type of message is it?

directed broadcast

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

tunneling

When will a router drop a traceroute packet?

when the value in the TTL field reaches zero
