PT Activity Wizard Vocabulary
 Answer network: The network that you want students
to end up with after they perform whatever
configuration tasks they are instructed to complete. The
“correct” answer.
 Initial network: The network that you give students to
begin with in completing the activity. This can be as
“complete” or incomplete as you like. Just remember
that you need to give clear instructions so that students
know what Answer network you are expecting.

Planning: Create the Answer first…
 Using the Activity Wizard is easier with a little up front planning.
 The easiest way to create activities using the wizard is to create
the Answer network first.
 By removing or editing elements of the answer network, the Initial
network is created.
… Or ...
 Import a .pkt file that already contains all or most of the elements
you might want to assess. This imported file becomes the Answer
network.

Variable Pools
There are three
possible variable
types.
Each pool may
then be associated
with a named
variable.
CCNA Overview
© 2009 Cisco Systems, Inc. All rights reserved.
Cisco Public
17
Variable Pools - Number
Use Number variables for a continuous range of values.
In this example, we are setting host IP address ranges
for each LAN in this network.
The first range will include all values between 10 and 49,
the second range is from 50 to 99.
When selected randomly, one value will be chosen from
each range for this Activity. Different values will occur
each time it is run.
CCNA Overview
© 2009 Cisco Systems, Inc. All rights reserved.
Cisco Public
18
Variable Pools - Strings
Use Strings to define a single value or a list of values. You
may create complex values using “Regular Expressions”.
For more information, visit:
http://www.regular-expressions.info
Multiple values are separated by semi-colons. When
assigning variables, either a random choice may be made
or the entire range may be compared for a matching
value.

Variable Pools - Strings
Name
Value
Wild-Match-Any
{{RegEx::^.+$}}
This will match any value
Wild-Not-Switch
{{RegEx:^((?!Switch).)*$}}
This matches anything but “Switch”
Match-class
class;$1$mERr$9cTjUIEqNGurQiFU.ZeCi1
This matches “class” or the hashed value for it
Match-cisco
cisco;0822455D0A16
This matches “cisco” or the hashed value for it
DNS-Server
172.25.72.2;140.198.8.14;217.23.44.197
This will match several different IP addresses
Login-Normal
1
This will match a single numeric value
PHX-SNM
255.255.255.192
This will match a Subnet Mask
Clock-Variable
9600;38400;56000;125000;1000000;4000000
Several possible Clock Rates

Variable Pools – IP Addresses
IP addresses and subnet masks are entered here. This
will define a range of values that is shown in the last two
columns.
Only the IP address is compared in the variable. If you
wish to compare a subnet mask, you must create a
string variable for it.

Associating Variables with Pools
This associates the pool information to the variable
name and specifies how it relates.

Answer Network – Lots goes on here!
You can view and modify
the answer network at
any time by clicking here.
You can import a different
answer network from an existing
.pkt file or export the current
answer network to a .pkt file.
The Answer Network screen allows you
to customize the activity’s answer
network, assessment options, timer
settings, connectivity testing, and
feedback options.

What Can be Assessed?
Assessment criteria are Vast-
Almost any value in any
device may be compared to
the Answer Network.
The Answer network used in
creating the activity will
dictate which items may be
assessed.
Connectivity tests may also
be created to verify that the
finished network actually
functions properly.

32
Assigning Values with Variables
Variables can be used in
place of absolute values. If
a random option is chosen,
the variable will take on a
value for that session only.
Variables may only be
selected for those values
that have a green circle in
front of them.
Simply select the assessment
criteria with a check mark,
and drag the variable from
the list to the item.

Assessment Options and Items
Only checked items will be evaluated. Be careful not to just
check a device at the outermost level – every item in the
device will become checked! Clicking on the ‘+’ sign will
expand a category.

Activity Timer
Time Elapsed tracks the time taken to complete an activity.
Countdown sets a time limit for completing the activity.
None turns the timer off.
The default is Time Elapsed.

Initial Network
The Show Initial Network button switches to
the Initial Network. It begins as an empty
topology, which means the student will start
from scratch. Not a very good idea!
Use the Copy from Answer Network
button to copy the answer network to
the initial network.
Then click on Show Initial Network
button and adjust the initial network so
that the assessed items are missing.
You can import a different
initial network from an
existing .pkt file or export
the current initial network
to a .pkt file.
The Initial Network screen allows you to set up the
initial network and lock certain options within PT.

can specify which features are

Lock View Assessment Items
Another popular choice is to
disable the ability for the
students to review their
individual assessment items.
They will still see a “% Done”.
Often students ‘chase’ green
check marks and lose the value
of the exercise.
