Total questions: 11
Worksheet time: 6mins
How does a router determine which interface to use to send a message to the destination network?
By using a routing table
By guessing the shortest path
By sending to all interfaces
By using the default gateway
What is the purpose of a routing table in a router?
To store user data
To determine the path for data packets
To connect to the internet
To manage user accounts
What does a router do if the destination network address is in the routing table?
It discards the packet.
It encapsulates the packet in a new frame to send it out.
It sends an error message to the sender.
It ignores the packet.
What happens if the wrong default gateway is specified in the host TCP/IP settings?
Messages are encrypted
Messages are delivered faster
Messages cannot be delivered
Messages are sent to the correct network
What is the function of the default gateway in message delivery?
It encrypts messages
It assigns IP addresses
It ensures messages reach remote networks
It increases network speed
Which of the following is not a valid IPv4 address in the diagram?
192.168.1.1
192.168.1.2
192.168.1.5
192.168.1.3
What is the common subnet mask for all PCs in the diagram?
255.255.255.0
255.255.0.0
255.0.0.0
255.255.255.255
What information in the IP packet does the router use to determine which interface to forward the packet?
Destination MAC Address
Source MAC address
Destination IP address
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
false
A default route is the interface through which the router forwards:
all packets
any packet when a host does not receive an ARP Reply
a packet containing a source IP network address that is not in the routing table of the router
a packet containing a destination IP network address that is not in the routing table of the router
A host will send a packet to the default gateway when
the source IP address is on a different network
the destination IP address is on a different network
IT does not receive an ARP Reply
all packets
