255.255.255.255
Which two types of devices are typically assigned static IP addresses? (Choose two.)
printers and web servers

443
What is the well-known port address number used by DNS to serve requests
53
A DHCP-enabled client PC has just booted. During which two steps will the client PC use broadcast messages when communicating with a DHCP server? (Choose two.)
DHCPREQUEST, DHCPDISCOVER
Open the PT activity. Perform the tasks in the activity instructions and then answer the question. What is the application layer service being requested from Server0 by PC0?
HTTPS
Which two statements are correct about IPv4 and IPv6 addresses? (Choose two.)
IPv4 addresses are 32 bits in length and IPv6 addresses are represented by hexadecimal numbers.
Which two reasons generally make DHCP the preferred method of assigning IP addresses to hosts on large networks? (Choose two.)
It eliminates most address configuration errors and it reduces the burden on network support staff.
What is a characteristic of UDP?
It provides unreliable delivery of segments.
Which method of IPv6 prefix assignment relies on the prefix contained in RA messages?
SLAAC
Which protocol operates at the transport layer of the TCP/IP model and ensures reliable delivery of IP packets?
TCP
Refer to the exhibit. A user is configuring a PC with the IP settings as displayed, but the operating system will not accept them. What is the problem?
The IP address is not a usable host address.
Which action is performed by a client when establishing communication with a server via the use of UDP at the transport layer?
The client randomly selects a source port number.
Typically, which network device would be used to perform NAT for a corporate environment?
router
Why is UDP well suited as the transport layer protocol for video applications?
UDP has low overhead.
What is an advantage of using IPv6 ?
more addresses for networks and hosts
Which statement is true about DHCP operation?
When a device that is configured to use DHCP boots, the client broadcasts a DHCPDISCOVER message to identify any available DHCP servers on the network.
What protocol header information is used at the transport layer to identify a target application?
port number
What type of applications are best suited for using UDP?
applications that are sensitive to delay
Which DHCPv4 message will a client send to accept an IPv4 address that is offered by a DHCP server?
broadcast DHCPREQUEST
Which transport layer information is added to both the TCP and UDP headers?
port numbers
If more than one DHCP server is available on the local network, in which order will DHCP messages be sent between a host and a DHCP server?
discover, offer, request, acknowledgement
Which network technology allows devices to communicate using both IPv4 and IPv6 addressing at the same time?
dual stack
Which is a DHCPv4 address allocation method that assigns IPv4 addresses for a limited lease period?
dynamic allocation
What type of IPv6 address is FE80::1?
link-local
