Networking basics module 12, 13 and 14

Name:

1.A computer has to send a packet to a destination host in the same LAN. How will the packet be sent?

• The packet will be sent to the default gateway first, and then, depending on the response from the gateway, it may be sent to the destination host.
• The packet will be sent directly to the destination host.
• The packet will first be sent to the default gateway, and then from the default gateway it will be sent directly to the destination host.
• The packet will be sent only to the default gateway.

2. What is the purpose of configuring a default gateway address on a host?

• to identify the device that allows local network computers to communicate with devices on other networks
• to identify the logical address of a networked computer and uniquely identify it to the rest of the network
• to identify the network to which a computer is connected
• to provide a permanent address to a computer

3. If the default gateway is configured incorrectly on a host, what is the impact on communications?

• The host is unable to communicate with hosts on both the local and remote networks.
• The host cannot get an IP address from the DHCP server.
• The host is unable to communicate on the local network.
• The host is unable to communicate with hosts on remote networks.

4. What is the purpose of NAT?

• allowing hosts configured with registered public IP addresses to access the internet
• translating private IP addresses to a public registered IP address
• routing private IP addresses over the public internet
• assigning a private IP address to a host for internet access

5. The default configuration on a home wireless router provides which type of addresses to devices using DHCP?

• private IP addresses
• public registered IPv4 addresses
• public registered IPv6 addresses
• vendor-specific MAC addresses

6. Which destination address is used in an ARP request frame?

• 0.0.0.0
• FFFF.FFFF.FFFF
• 127.0.0.1
• 01-00-5E-00-AA-23

7. Which statement describes the treatment of ARP requests on the local link?

• They must be forwarded by all routers on the local network.
• They are received and processed by every device on the local network.
• They are dropped by all switches on the local network.
• They are received and processed only by the target device.

8. What addresses are mapped by ARP?

• destination IPv4 address to the source MAC address
• IPv4 address to a destination MAC address
• destination IPv4 address to the destination host name
• destination MAC address to the source IPv4 address

9. What statement describes a characteristic of MAC addresses?

• They have a 32-bit binary value.
• They are added as part of a Layer 3 PDU.
• They are only routable within the private network.
• They are the physical address of the NIC or interface.
