00:00:07,500 --> 00:00:11,320
Congratulations on
completing another skill.

5
00:00:11,320 --> 00:00:16,000
Now it's time for a review
in the form of a quiz.

6
00:00:16,000 --> 00:00:18,120
As we go through
these questions,

7
00:00:18,120 --> 00:00:22,680
be sure to pause the video after
each question to give yourself

8
00:00:22,680 --> 00:00:25,470
the opportunity to answer
the question yourself

9
00:00:25,470 --> 00:00:27,930
before we then go
over the answer.

10
00:00:27,930 --> 00:00:32,720
That said, let's jump in
with our first question.

11
00:00:32,720 --> 00:00:36,850
What are the six processes
used in traffic engineering?

12
00:00:36,850 --> 00:00:42,630

13
00:00:42,630 --> 00:00:45,210
Now, this answer, of
course, is unfortunately

14
00:00:45,210 --> 00:00:47,670
just a matter of memorization.

15
00:00:47,670 --> 00:00:51,930
But our first process is
information distribution.

16
00:00:51,930 --> 00:00:55,620
Our second process
is path selection.

17
00:00:55,620 --> 00:00:58,740
Third is the path setup.

18
00:00:58,740 --> 00:01:01,470
Fourth is admission
control, where

19
00:01:01,470 --> 00:01:04,709
routers say whether they can
handle the tunnel or not.

20
00:01:04,709 --> 00:01:07,770
Five is traffic steering,
which is getting

21
00:01:07,770 --> 00:01:09,870
the traffic into the tunnel.

22
00:01:09,870 --> 00:01:13,350
And six is path
maintenance, which

23
00:01:13,350 --> 00:01:17,370
involves rerouting the tunnel
or possibly even reestablishing

24
00:01:17,370 --> 00:01:18,280
it.

25
00:01:18,280 --> 00:01:23,610
So these are the six traffic
engineering processes.

26
00:01:23,610 --> 00:01:27,830
Next question, how many
tunnel priority levels are

27
00:01:27,830 --> 00:01:30,760
available for MPLS TE tunnels?

28
00:01:30,760 --> 00:01:36,830

29
00:01:36,830 --> 00:01:39,220
So to answer this,
we need to remember

30
00:01:39,220 --> 00:01:41,500
that the priority
levels themselves

31
00:01:41,500 --> 00:01:44,620
are zero through seven.

32
00:01:44,620 --> 00:01:48,250
Now, at first, that might
make answer one look

33
00:01:48,250 --> 00:01:49,760
like a correct answer.

34
00:01:49,760 --> 00:01:52,150
But remember, when
we're including zero,

35
00:01:52,150 --> 00:01:55,160
we can't just use the
top number as the range.

36
00:01:55,160 --> 00:01:58,810
So the answer here is
actually not number one.

37
00:01:58,810 --> 00:02:04,150
That's actually eight values,
making two the correct answer.

38
00:02:04,150 --> 00:02:06,100
As far as the rest
of them, they're

39
00:02:06,100 --> 00:02:07,870
pretty straightforward
that they're not

40
00:02:07,870 --> 00:02:09,139
the correct answers.

41
00:02:09,139 --> 00:02:12,400
So again, number two
is our correct answer.

42
00:02:12,400 --> 00:02:19,470
We have eight priority levels,
numbered zero through seven.

43
00:02:19,470 --> 00:02:22,530
Final question, which
of the following

44
00:02:22,530 --> 00:02:26,535
can be used to steer
traffic into a TE tunnel?

45
00:02:26,535 --> 00:02:32,550

46
00:02:32,550 --> 00:02:36,530
So once again, this is sort of
just a matter of memorization

47
00:02:36,530 --> 00:02:38,280
or thinking it through.

48
00:02:38,280 --> 00:02:40,340
The first one is autoroute.

49
00:02:40,340 --> 00:02:44,090
We can definitely use autoroute
to get traffic into the tunnel.

50
00:02:44,090 --> 00:02:47,750
We can use PBR, or
Policy-Based Routing.

51
00:02:47,750 --> 00:02:51,140
And we can use static routing.

52
00:02:51,140 --> 00:02:54,710
Technically, could we
maybe find some way

53
00:02:54,710 --> 00:02:58,250
to manipulate EIGRP,
RIP, or multiprotocol

54
00:02:58,250 --> 00:03:02,270
BGP to steer traffic
into the TE tunnel?

55
00:03:02,270 --> 00:03:03,080
Yes.

56
00:03:03,080 --> 00:03:05,660
But those are not the
main ways that we do it.

57
00:03:05,660 --> 00:03:08,790
We're normally going to use
one of these three options--

58
00:03:08,790 --> 00:03:12,410
number one, autoroute;
number three, PBR;

59
00:03:12,410 --> 00:03:14,480
number six, static routing--

60
00:03:14,480 --> 00:03:17,630
making those the correct answer.

61
00:03:17,630 --> 00:03:19,790
So that concludes this quiz.

62
00:03:19,790 --> 00:03:22,270
If you find that you were
missing any of the information

63
00:03:22,270 --> 00:03:24,190
to answer these
questions, I would

64
00:03:24,190 --> 00:03:27,880
encourage you to go back and
review the sources referenced

65
00:03:27,880 --> 00:03:29,750
on each question.

66
00:03:29,750 --> 00:03:33,940
Otherwise, congratulations
on completing Exploring

67
00:03:33,940 --> 00:03:36,280
MPLS Traffic Engineering.

68
00:03:36,280 --> 00:03:38,680
I hope this has been
informative for you,

69
00:03:38,680 --> 00:03:41,880
and I'd like to thank
you for viewing.
