Networking Essentials - Chapter 8

A network design engineer has been asked to design the IP addressing scheme for a customer network. The network will use IP addresses from the 192.168.30.0/24 network. The engineer allocates 254 IP addresses for the hosts on the network but excludes 192.168.30.0/24 and 192.168.30.255/24 IP addresses. Why must the engineer exclude these two IP addresses?

• 192.168.30.0/24 is the IP address reserved for the default gateway, and 192.168.30.255/24 is the IP address reserved for the DHCP server
• 192.168.30.0/24 and 192.168.30.255/24 IP addresses are reserved for the email and DNS server
• 192.168.30.0/24 and 192.168.30.255/24 are reserved for outside Internet connectivity
• 192.168.30.0/24 is the network IP address and 192.168.30.255/24 is the IP broadcast address.

What are three private IPv4 address? (Choose three.)

• 192.167.10.10
• 192.168.5.5
• 10.1.1.1
• 172.32.5.2
• 172.16.4.4

Which address prefix range is reserved for IPv4 multicast?

• 127.0.0.0-172.255.255.255
• 169.254.0.0-169.254.255.255
• 240.0.0.0-254.255.255.255
• 224.0.0.0-239.255.255.255

Why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask?

• to identify the network address of the destination network
• to identify faulty frames
• to identify the host address of the destination host
• to identify the broadcast address of the destination network

What are three characteristics of a multicast transmission? (Choose three.)

• Multicast messages map lower layer addresses to upper layer addresses
• Multicast transmissions can be used by routers to excahnge routing information
• Computers use multicast transmission to request IPv4 addresses
• A single packet can be sent to a group of hosts
• Routers will not forward multicast addresses in the range of 244.0.0.0-224.0.0.255

When IPv4 is configured for a computer on a network, what does the subnet mask identify?

• the device that the computer uses to access another network
• the pool of addresses assigned within the network
• the part of the IP address that identifies the network
• the dynamic subnetwork configuration

Which network does a host with IP address 172.32.65.13 reside on if it is using a default subnet mask?

• 172.32.32.0
• 172.32.65.0
• 172.32.65.32
• 172.32.0.0

A technician is setting up equipment on a network. Which three devices will need IP addresses? (Choose three.)

• a printer with an integrated NIC
• an IP phone
• a web camera that is attached directly to a host
• a wireless mouse
• a server with two NICs

Which IP address type is intended for a specific host?

• unicast
• simulcast
• broadcast
• multicast

What is the equivalent decimal value given a binary number of 11001010?

• 212
• 202
• 240
• 196
