A DHCP server is used to assign IP addresses dynamically to the hosts on a network. The address pool is configured with 172.30.8.0/24. There are 7 printers on this network that need to use reserved static IP addresses from the pool. How many IP addresses in the pool are left to be assigned to other hosts?
247
Refer to the exhibit. PC1 is configured to obtain a dynamic IP address from the DHCP server. PC1 has been shut down for two weeks. When PC1 boots and tries to request an available IP address, which destination IP address will PC1 place in the IP header?
255.255.255.255
How is a DHCPDISCOVER transmitted on a network to reach a DHCP server?
A DHCPDISCOVER message is sent with the broadcast IP address as the destination address.
A host PC is attempting to lease an address through DHCP. What message is sent by the server to let the client know it is able to use the provided IP information?
DHCPACK
Which message does an IPv4 host use to reply when it receives a DHCPOFFER message from a DHCP server?
DHCPREQUEST

HTML
protocol commonly used by a web browser
HTTP
secure protocol that uses port 443

What purpose does NAT64 serve in IPv6?
It converts IPv6 packets into IPv4 packets.
What is a function of a DNS server?
It determines the IP address that is associated with a specific host domain name
Why is DHCP for IPv4 preferred for use on large networks?
It is a more efficient way to manage IPv4 addresses than static address assignment is
Which statement accurately describes dynamic NAT?
It provides an automated mapping of inside local to inside global IP addresses.
Which two protocols are used in the process of sending and receiving emails?
POP and SMTP
Which two applications provide virtual terminal access to remote servers?
SSH and Telnet
What is the result if the default gateway address is misconfigured on a PC?
The PC can communicate with devices in the same network but not with those in remote networks.
How does a client computer determine what source port number to assign to a UDP header?
The port number is random within the range of dynamic port numbers.
What layer of the TCP/IP suite makes sure that all the data packets of a message arrive safely at the destination?
Transport
What is an advantage of UDP over TCP?
UDP communication requires less overhead.
Hosts a web site
Web Server
Which type of applications are best suited to use UDP as the transport layer protocol?
applications that require minimal transmission delay

link-local address
Which three types of nodes should be assigned static IP addresses on a network?
servers, printers, and gateways
What is a socket?
the combination of a source IP address and port number or a destination IP address and port number
Which three pieces of information are identified by a URL?
the protocol that is being used the domain name that is being accessed the location of the resource
What is the purpose of using a source port number in a TCP communication?
to keep track of multiple conversations between devices
