Presuming it has an IP address available, the DHCP server

-responds to the client with a DHCPOFFER packet, containing the address
and other configuration information, such as default gateway and DNS
server addresses. The client may choose to accept the offer using a
DHCPREQUEST packet that is also broadcast onto the network.
-Assuming the offer is still available, the server will respond with a
DHCPACK packet. The client broadcasts an ARP message to check that the
address is unused. If so, it will start to use the address and options; if not, it
declines the address and requests a new one.
The DNS server IP addresses configured on a client machine

, are used to resolve the client's queries for hosts and domains across the
Internet. At least one DNS server also needs to be configured to act as an
authoritative store of information about each domain. These name servers
are normally installed separately from the ones used as client resolvers.
Address (A) and Address (AAAA) Resource Records
Give this one a try later!
An address (A) record is used to resolve a host name to an IPv4 address.
An AAAA record resolves a host name to an IPv6 address.
Scope

Range of consecutive IP addresses in the same subnet that a DHCP server
can lease to clients.
HTTPS

, -Application protocol used to provide web content to browsers. HTTP uses
port 80. HTTPS(ecure) provides for encrypted transfers, using TLS and port
443.
-This protocol is used to deliver web pages and other resources. The
secure version uses encryption to authenticate the server and protect the
information that is being transmitted. A single missing packet would cause
this process to fail completely.
A Mail Exchange (MX) record

is used to identify an email server for the domain so that other servers can
send messages to it. In a typical network, multiple servers are installed to
provide redundancy, and each one will be represented by an MX record.
Each MX record is given a preference value, with the lowest numbered
entry preferred. The host name identified in an MX record must have an
associated A or AAAA record.
Virtual LAN
Give this one a try later!
Logical network segment comprising a broadcast domain established using
a feature of managed switches to assign each port a VLAN ID. Even though
hosts on two VLANs may be physically connected to the same switch, local
traffic is isolated to each VLAN, so they must use a router to communicate.
True or false? At the Transport layer, connections between hosts to exchange
application data are established over a single port number.
