Congratulations on completing another skill.
Now it's time for a review in the form of a quiz.
As we go through these questions,
be sure to pause the video after each question to give yourself
the opportunity to answer the question yourself
before we then go over the answer.
That said, let's jump in with our first question.
Define the following terms--
P space and Q space.
These being fill-in-the-blank answers,
we're simply looking for something similar to these
answers.
The P space is the set of nodes that
are reachable without using the protected link.
So keep in mind that this would be from the perspective
of the point of local repair.
The Q space, on the other hand, is
the set of nodes that can actually
reach the destination--
still, of course, without using the protected link.
So, again, the P space are the nodes
that are reachable from the point of local repair,
and the Q space are the nodes that
can reach the destination, both of which
without using the link that we're trying to protect.
Next question, which of the following protocols
are used for the control plane in segment routing?
So if we go down our list, the first one is OSPF,
and this is correct.
OSPF will function as the control
plane for segment routing.
Next is RSVP.
RSVP is actually one of the protocols
that we're going to be getting rid of in segment routing,
so that's not going to be one of our correct choices.
IS-IS, of course, can be used instead of OSPF,
so that is an acceptable choice.
We can also use BGP.
Again, this is normally done between domains,
but it can be used in any situation.
And, finally, LDP, this is the other protocol
that we're eliminating by going to segment routing.
So our correct choices here are going to be 1, 3, and 4.
Final question, which LSA type is
used for distributing segment routing labels when using OSPF?
So this one is really just a matter of memorization,
so you have to just sort of remember
that we're going to be using type 10 opaque LSAs.
So that makes 6 our correct answer.
Now, keep in mind, there are subtypes that are used here,
and we will see that more in an upcoming skill.
But overall, they are type 10 opaque LSAs.
So that concludes this quiz.
If you find you are missing any of the information
to answer these questions, I would
encourage you to review the referenced sources
on each question.
Otherwise, congratulations on completing Discovering Segment
Routing.
I hope this has been informative for you,
and I'd like to thank you for viewing.
