In this section of the course,
we're going to discuss network services.
Now, a network service is a function
that's provided by the network infrastructure
to support various types of communications
and processes like assigning IP addresses,
translating domain names to IP addresses,
synchronizing our network's time,
and managing our quality of service.
So we're going to focus on Domain 1, networking concepts,
and Domain 3, network operations
in this part of the course.
We're going to focus briefly on Objective 1.2, which states
that you must be able to compare and contrast networking
appliances, applications, and functions.
We'll also cover Objective 3.4, which states
that given a scenario, you must be able
to implement IP Version 4
and IP Version 6 network services.
Now first we're going to be looking at DHCP
or the Dynamic Host Configuration Protocol Service.
DHCP is used to automatically assign IP addresses
and other network configuration information to a client.
Now, we'll also do a hands-on demonstration,
so you can see how DHCP works out in the real world.
Then we're going to discuss
the Stateless Address Autoconfiguration protocol
known as SLAAC.
Now SLAAC is used in IPv6 to allow a client
to configure itself with a public IPV six address
without the need for a DHCP server.
Next, you'll learn all about DNS
or the Domain Name System, including how it works,
the different types of DNS records contained
within the system, methods for securing DNS,
and a demonstration of how DNS works out in the real world.
After that, we'll cover the Network Time Protocol,
also known as NTP, since it's critically important
to maintain a well synchronized
and accurate time for all of our network connected devices.
Then we're going to discuss the concepts
surrounding quality of service,
including the different methods used
to categorize our traffic
and the different mechanisms used to provide higher levels
of service based on the different types of traffic
being transmitted over our networks.
Finally, we'll take a short quiz to see what you learned
during this section of the course and review your answers
to ensure you know why the right answers were right
and the wrong answers were wrong.
So if you're ready, let's get started with our coverage
of network services in this section of the course.
