Q
  1. An administrator wants to create four subnetworks from the network address 192.168.1.0/24. What is the network address and subnet mask of the second useable subnet?

subnetwork 192.168.1.64
subnet mask 255.255.255.192
subnetwork 192.168.1.32
subnet mask 255.255.255.240
subnetwork 192.168.1.64
subnet mask 255.255.255.240
subnetwork 192.168.1.128
subnet mask 255.255.255.192
subnetwork 192.168.1.8
subnet mask 255.255.255.224

A

subnetwork 192.168.1.64
subnet mask 255.255.255.192

Explanation: The number of bits that are borrowed would be two, thus giving a total of 4 useable subnets:
192.168.1.0
192.168.1.64
192.168.1.128
192.168.1.192
Because 2 bits are borrowed, the new subnet mask would be /26 or 255.255.255.192

R: 172.16.19.255

Explanation: The 172.16.16.0/22 network has 22 bits in the network portion and 10 bits in the host portion. Converting the network address to binary yields a subnet mask of 255.255.252.0. The range of addresses in this network will end with the last address available before 172.16.20.0. Valid host addresses for this network range from 172.16.16.1-172.16.19.254, making 172.16.19.255 the broadcast address.

A

VER IMAGEM

R: 10.16.10.64/27

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

A

62

Explanation: A /26 mask is the same as 255.255.255.192. The mask leaves 6 host bits. With 6 host bits, 64 IP addresses are possible. One address represents the subnet number and one address represents the broadcast address, which means that 62 addresses can then be used to assign to network devices.

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

limited broadcast
multicast
directed broadcast
unicast

A

directed broadcast

Explanation: A directed broadcast is a message sent to all hosts on a specific network. It is useful for sending a broadcast to all hosts on a nonlocal network. A multicast message is a message sent to a selected group of hosts that are part of a subscribing multicast group. A limited broadcast is used for a communication that is limited to the hosts on the local network. A unicast message is a message sent from one host to another.

192.168.1.64/27
192.168.1.128/27
192.168.1.96/28
192.168.1.192/28

A

192.168.1.64/27
192.168.1.96/28

Explanation: Subnet 192.168.1.64 /27 has 5 bits that are allocated for host addresses and therefore will be able to support 32 addresses, but only 30 valid host IP addresses. Subnet 192.168.1.96/28 has 4 bits for host addresses and will be able to support 16 addresses, but only 14 valid host IP addresses.

3FFE:1044:0000:0000:00AB::0057

A

3FFE:1044:0:0:AB::57

Explanation: The rules for reducing the notation of IPv6 addresses are:
1. Omit any leading 0s (zeros) in any hextet.
2. Replace any single, contiguous string of one or more 16-bit hextets consisting of all zeros with a double colon (::) .
3. The double colon (::) can only be used once within an address.

Q
  1. What is used in the EUI-64 process to create an IPv6 interface ID on an IPv6 enabled interface?

the MAC address of the IPv6 enabled interface
a randomly generated 64-bit hexadecimal address
an IPv6 address that is provided by a DHCPv6 server
an IPv4 address that is configured on the interface

A

the MAC address of the IPv6 enabled interface

Explanation: The EUI-64 process uses the MAC address of an interface to construct an interface ID (IID). Because the MAC address is only 48 bits in length, 16 additional bits (FF:FE) must be added to the MAC address to create the full 64-bit interface ID.

2001:DB8:BC15:A:1
2001:DB8:BC15:A:12

A

2001:DB8:BC15:A

Explanation: The network portion, or prefix, of an IPv6 address is identified through the prefix length. A /64 prefix length indicates that the first 64 bits of the IPv6 address is the network portion. Hence the prefix is 2001:DB8:BC15:A.

31
Q
  1. An IPv6 enabled device sends a data packet with the destination address of FF02::1. What is the target of this packet?​

the one IPv6 device on the link that has been uniquely configured with this address
all IPv6 enabled devices on the local link​ or network
only IPv6 DHCP servers​
only IPv6 configured routers

A

all IPv6 enabled devices on the local link​ or network

Explanation: 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.

32
Q

Explanation: SLAAC uses ICMPv6 messages when dynamically assigning an IPv6 address to a host. DHCPv6 is an alternate method of assigning an IPv6 addresses to a host. ARPv6 does not exist. Neighbor Discovery Protocol (NDP) provides the functionality of ARP for IPv6 networks. UDP is the transport layer protocol used by DHCPv6.

Q
  1. Which protocol is used by the traceroute command to send and receive echo-requests and echo-replies?

SNMP
ICMP
Telnet
TCP

A

ICMP

Explanation: Traceroute uses the ICMP (Internet Control Message Protocol) to send and receive echo-request and echo-reply messages.

42
Q
  1. Which ICMPv6 message is sent when the IPv6 hop limit field of a packet is decremented to zero and the packet cannot be forwarded?

network unreachable
time exceeded
protocol unreachable
port unreachable

A

time exceeded

Explanation: ICMPv6 uses the hop limit field in the IPv6 packet header to determine if the packet has expired. If the hop limit field has reached zero, a router will send a time exceeded message back towards the source indicating that the router cannot forward the packet.

43
Q
  1. A user executes a traceroute over IPv6. At what point would a router in the path to the destination device drop the packet?

when the value of the Hop Limit field reaches 255
when the value of the Hop Limit field reaches zero
when the router receives an ICMP time exceeded message
when the target host responds with an ICMP echo reply message

A

when the value of the Hop Limit field reaches zero

Explanation: When a traceroute is performed, the value in the Hop Limit field of an IPv6 packet determines how many router hops the packet can travel. Once the Hop Limit field reaches a value of zero, it can no longer be forwarded and the receiving router will drop the packet.

44
Q
  1. What is the purpose of ICMP messages?

to inform routers about network topology changes
to ensure the delivery of an IP packet
to provide feedback of IP packet transmissions
to monitor the process of a domain name to IP address resolution

A

to provide feedback of IP packet transmissions

Explanation: The purpose of ICMP messages is to provide feedback about issues that are related to the processing of IP packets.

45
Q
  1. What source IP address does a router use by default when the traceroute command is issued?

the highest configured IP address on the router
a loopback IP address
the IP address of the outbound interface
the lowest configured IP address on the router

A

the IP address of the outbound interface

Explanation: When sending an echo request message, a router will use the IP address of the exit interface as the source IP address. This default behavior can be changed by using an extended ping and specifying a specific source IP address.

46
Q
  1. Match each description with an appropriate IP address. (Not all options are used.)
A

Explanation: Link-Local addresses are assigned automatically by the OS environment and are located in the block 169.254.0.0/16. The private addresses ranges are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. TEST-NET addresses belong to the range 192.0.2.0/24. The addresses in the block 240.0.0.0 to 255.255.255.254 are reserved as experimental addresses. Loopback addresses belong to the block 127.0.0.0/8.

47
Q
  1. A user issues a ping 192.135.250.103 command and receives a response that includes a code of 1. What does this code represent?

host unreachable
protocol unreachable
port unreachable
network unreachable

A

host unreachable

48
Q
  1. Which subnet would include the address 192.168.1.96 as a usable host address?

192.168.1.64/26
192.168.1.32/27
192.168.1.32/28
192.168.1.64/29

A

192.168.1.64/26

Explanation: For the subnet of 192.168.1.64/26, there are 6 bits for host addresses, yielding 64 possible addresses. However, the first and last subnets are the network and broadcast addresses for this subnet. Therefore, the range of host addresses for this subnet is 192.168.1.65 to 192.168.1.126. The other subnets do not contain the address 192.168.1.96 as a valid host address.

R:
2001:DB8:1:1::1
2001:DB8:1:2::1
2001:DB8:1:3::2

Explanation: Using the ipv6config command on PC2 displays the IPv6 address of PC2, which is 2001:DB8:1:4::A. The IPV6 link-local address, FE80::260:70FF:FE34:6930, is not used in route tracing. Using the tracert 2001:DB8:1:4::A command on PC1 displays four addresses: 2001:DB8:1:1::1, 2001:DB8:1:2::1 , 2001:DB8:1:3::2, and 2001:DB8:1:4::A.
