What is the default gateway of H3?

172.16.0.50

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

172.32.0.0

What is the default gateway of H1?

192.168.1.1

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 network IP address and 192.168.30.255/24 IP addresses are reserved for the email and DNS servers.

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

192.168.5.5 172.16.4.4 10.1.1.1

What are two differences between binary and decimal numbers? (Choose two.)

Binary numbers are based on powers of 2; decimal numbers include 0 through 9.

Refer to the exhibit. The IP address of which device interface should be used as the default gateway setting of host H1?

R1: G0/0

A default route is the interface through which the router forwards:

a packet containing a destination IP network address that is not in the routing table of the router

What will a router do if it cannot determine where to forward an incoming packet?

The router will drop it.

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

a server with two NICs, an IP phone and a printer with an integrated NIC

A router receives a packet from the Gigabit 0/0 interface and determines that the packet needs to be forwarded out the Gigabit 0/1 interface. What will the router do next?

create a new Layer 2 Ethernet frame to be sent to the destination

What information in the IP packet does the router use to determine which interface to forward the packet?

destination IP address

Which information is used by routers to forward a data packet toward its destination?

destination IP address

What type of route is indicated by the code C in an IPv4 routing table on a Cisco router?

directly connected route

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

the part of the IP address that identifies the network.

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

True or false? If Host-A has an IP packet to send to Host-B, and Host-A has determined that Host-B is on a different network. Host-A will encapsulate the IP packet in an Ethernet frame with the destination MAC address of the its default gateway.

true

Which IP address type is intended for a specific host?

unicast

What is the default gateway of H2?

10.0.0.1

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

202

Which address prefix range is reserved for IPv4 multicast?

224.0.0.0 - 239.255.255.255

How many usable hosts are available given a Class C IP address with the default subnet mask?

254

In implementing a LAN in a corporation, what are three advantages of dividing hosts between multiple networks connected by a distribution layer? (Choose three.)

It provides increased security. It splits up broadcast domains and decreases traffic. It makes the hosts invisible to those on other local network segments.

A router receives an incoming packet and determines that the destination host is located on a LAN directly attached to one of the router interfaces. Which destination address will the router use to encapsulate the Ethernet frame when forwarding the packet?

MAC address of the destination host

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

Routers will not forward multicast addresses in the range of 224.0.0.0 to 224.0.0.255; a single packet can be sent to a group of hosts; multicast transmission can be used by routers to exchange routing information.

Which portion of the network layer address does a router use to forward packets?

network portion

What role does a router play on a network?

selecting the path to destination networks

During the process of forwarding traffic, what will the router do immediately after matching the destination IP address to a network on a directly connected routing table entry?

switch the packet to the directly connected interface

Which address should be configured as the default gateway address of a client device?

the IPv4 address of the router interface that is connected to the same LAN

A host will send a packet to the default gateway when:

the destination IP address is on a different network
