Chapter 4 Network Essentials Exam
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
Which IP address type is intended for a specific host?
unicast
Which destination IPv4 address does a DHCPv4 client use to send the initial DHCP Discover packet when the client is looking for a DHCP server?
255.255.255.255
Which function does NAT perform in a wireless router?
NAT takes an internal source IP address and translates it to a global IP address.
Refer to the exhibit. A technician has configured a user workstation with the information shown. Although the user can access all local LAN resources, the user cannot access any Internet sites by using either domain names or IP addresses. What is causing this failure? The DNS server addresses are incorrect. The default gateway address is incorrect. The wrong subnet mask was assigned to the workstation. The workstation is not in the same network as the DNS servers.
The default gateway address is incorrect.

What are three characteristics of multicast transmission? (Choose three.) A: The source address of a multicast transmission is in the range of 224.0.0.0 to 224.0.0.255. B: A single packet can be sent to a group of hosts. C: Multicast transmission can be used by routers to exchange routing information. D: The range of 224.0.0.0 to 224.0.0.255 is reserved to reach multicast groups on a local network. E: Computers use multicast transmission to request IPv4 addresses. F: Multicast messages map lower layer addresses to upper layer addresses.
