I'll be posting a series of Linux-related questions covering various skill levels. Feel free to share your insights and expertise. Your contributions will benefit learners at all stages, from those in current roles to those preparing for Linux interviews.
What is the difference between Response SLA and Resolution SLA as per ITIL terminology.
In ITIL, a service level agreement (SLA) defines the expected level of
service and the responsibilities of an IT service provider and their customer:
Response time: How quickly the provider will respond to a request for support
Resolution time: How quickly the provider will resolve an issue
In ITIL terminology, a "Response SLA" refers to the time frame within which
a service provider must acknowledge and respond to a customer's incident
or request, while a "Resolution SLA" refers to the total time taken to completely
resolve that issue once it has been reported. Essentially, the response time is
when the customer receives initial contact, and the resolution time is when
the problem is fully fixed.
Response SLA focuses on initial contact:
This means the service provider must acknowledge the issue and
provide a response within a specified time frame, even if they
haven't fully resolved it yet.
Resolution SLA focuses on complete problem resolution:
This includes the entire process from when the issue is reported
to when it is fully fixed and closed.
Here is an example of each one:
Response SLA:
A service provider might have a "response SLA" of 15 minutes, meaning
they must acknowledge a customer's support ticket within 15 minutes
of it being submitted.
Resolution SLA:
The "resolution SLA" for the same issue might be 12 hours, indicating
that the problem should be completely resolved within 12 hours of
the initial report.

If the network interface ain't starting up when the system boots, where
do we begin?
I would take a different approach to troubleshoot a network interface was not
functioning, due to something other than failing to start on bootup.
@Trevor think here about the network interface setting file and the option to enable it on boot.

@Trevor You are the ITIL "prince"!! Wonderful explanation!

Answer: I won't be greedy, and gobble up all the queries. I'll hold off on responding
to this one for a max of 24 hours. If there are no takers by then, I'll go ahead and
weigh in. 24-hr Expiration: 12:57am CST/10-27-2024
@Trevor The golf course is yours to conquer!
