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.
What are the six processes used in traffic engineering?
Now, this answer, of course, is unfortunately
just a matter of memorization.
But our first process is information distribution.
Our second process is path selection.
Third is the path setup.
Fourth is admission control, where
routers say whether they can handle the tunnel or not.
Five is traffic steering, which is getting
the traffic into the tunnel.
And six is path maintenance, which
involves rerouting the tunnel or possibly even reestablishing
it.
So these are the six traffic engineering processes.
Next question, how many tunnel priority levels are
available for MPLS TE tunnels?
So to answer this, we need to remember
that the priority levels themselves
are zero through seven.
Now, at first, that might make answer one look
like a correct answer.
But remember, when we're including zero,
we can't just use the top number as the range.
So the answer here is actually not number one.
That's actually eight values, making two the correct answer.
As far as the rest of them, they're
pretty straightforward that they're not
the correct answers.
So again, number two is our correct answer.
We have eight priority levels, numbered zero through seven.
Final question, which of the following
can be used to steer traffic into a TE tunnel?
So once again, this is sort of just a matter of memorization
or thinking it through.
The first one is autoroute.
We can definitely use autoroute to get traffic into the tunnel.
We can use PBR, or Policy-Based Routing.
And we can use static routing.
Technically, could we maybe find some way
to manipulate EIGRP, RIP, or multiprotocol
BGP to steer traffic into the TE tunnel?
Yes.
But those are not the main ways that we do it.
We're normally going to use one of these three options--
number one, autoroute; number three, PBR;
number six, static routing--
making those the correct answer.
So that concludes this quiz.
If you find that you were missing any of the information
to answer these questions, I would
encourage you to go back and review the sources referenced
on each question.
Otherwise, congratulations on completing Exploring
MPLS Traffic Engineering.
I hope this has been informative for you,
and I'd like to thank you for viewing.
