Few Questions & Answers
collected from different online & offline sources for HP0-M103
certifications.
Part 1
Q1) what does DFE
(Data format extension) support for?
A) Enables
easier scripting of web applications by providing the ability to decode and
encode formatted
data that is exchanged between client and server.

Q2) what was the
LoadRunner testing process?
A) 1) Plan the
load test;
2) Create the scripts;
3) Create the scenarios;
4) Executive the scenarios;
5) Analyse the results;
6) Optimise the system;
Q3) LoadRunner provided
default actions
A) Vuser_Init
Action
Vuser_end
Q4) If you are
modifying the script from the controller, in order to reflect the changes of
the script in the controller, what action you need to be performed?
A) Refresh the
script in the controller
Q5) What MI Listener
do in the loadrunner?
A) To enable
'running Vusers' or 'monitoring' over a firewall, you need to install the MI
Listener on one or more machines in the same LAN as the Controller outside the
firewall.
The Controller installation automatically
includes the MI Listener, so you can designate the Controller as the MI
Listener machine.
The MI Listener can only be installed on
Windows machines.
Q6) How do you set up
your LoadRunner system over Firewalls?
A) Setting up
your system to work with Firewalls involves the following stages of
configuration
1) Install the 'over-firewall' components;
2) Perform initial configuration of the 'over
– firewall' system;
3) Configure the LoadRunner Agent;
4) Connect the controller to load generator
and MI Listener machines;
5) Define what to monitor on your servers;
6) Check connectivity.
7Q) Where can we
print the controller messages in controller?
A) Controller
output window
lr_output_message -> sends a special
notification to output window
lr_log_message-> sends output message
directly to a file output.
lr_vuser_status_message - > Generates
& prints formatted output messages to controller vuser status area.
Q8) What is SLA
failure?
A) The Actual
SLA is not meeting the defined SLA (expected).
Q9) Program on error
handling
A) Sample
transaction is provided below.
Text1can be a parameter or
co-relation an needs to be registered before the transaction.
lr_start_transaction("01_Application_Launch");
web_url("index.htm",
"URL=http://127.0.0.1:1080/WebTours/index.htm",
"TargetFrame=",
"Resource=0",
"RecContentType=text/html",
"Referer=",
"Snapshot=t1.inf",
"Mode=HTML",
LAST);
if(atoi(lr_eval_string("{Text1}"))>0)
{
lr_end_transaction ("01_WebTours_Launch", LR_PASS);
}
else
{
lr_end_transaction("01_WebTours_Launch",LR_FAIL);
lr_error_message("%s",lr_eval_string("Login is failed for
this user {VuserID} Iteration number {Iteration_Number}"));
}
Q9-A) What does the
statement lr_end_transaction ("01_WebTours_Launch", LR_PASS);” tells
us?
A) you can manually
set the status of any transaction using status attribute.
LR_PASS:- For Success
LR_FAIL:- For Failure
LR_AUTO:- value will be
automatically assigned
LR_STOP:- For Aborted
Q10) Where can we set limit
only for 50 users in loadrunner?
A) Runtime
settings
Q11) What is workload
modelling?
A) Distribution of
Virtual users along the different scripts with calculated Pacing and thinktime.
Q12) How do you know the
status of every Vuser during a test run?
A) Click on Vusers
button on controllers tab
Q13) How many Vusers can be
run in the virtual user generator?
A) 1 (only one user
per vugen script)
Q14) The maximum number of
transactions that can be present in script is?
A) No limit (or) any
number of transactions
Q15) How many iterations
that can keep in virtual user generator?
A) Any number
Q16) Hits per second is
used in analysing?
A) Scalability of
the Applications.
Q17) what is the maximum
number of vusers that can be generated from load generator?
A) depends upon the
license and load generator capacity.
Q18) which system process
helps generating the load in loadrunner?
A) LoadRunner Agent
process
Q19) Hits is defined
as
A) HTTP
requests made by Vusers to the Web server
Q20) The download time of
each page in the script and its components and at what point during download
time problems occurred can be found out in
A) page break down
graph
Q21) How do we get response
times of various pages?
A) By defining
transactions
Q22) What is the function
submitting forms in web script?
A) web_submit_data
()
Q23) What are the modes of
viewing a script?
A) Tree view and
script view
Q24) Why do we put text
checks in the script?
A) To validate the
the actual page is same as expected. LR by itself cannot judge whether the
returned page is the required page .Hence we will have to explicitly put page
checks.
Q25) lr_whoami ?
A) lr_whoami -
retrieves information about a Vuser and places it into a message string. The
message string contains Vuser login information that connects with a server.
Memory for vuser_group is
allocated automatically. Do not alter the string.int id, scid;
char *vuser_group;
lr_whoami(&id,
&vuser_group, &scid);
lr_message( "Group:
%s, vuser id: %d, scenario id %d", vuser_group, id, scid);
Q26) What is vuser script?
A) The actions that
a vuser performs during the scenario are described as vuser script.
Q27) What are the different
states of a Vuser crosses before it comes to run state?
A) Down, Pending,
Init and Ready.
Q28) Relation between Hits
per second and Throughput?
A) directly
proportional
Hits per Second - Pag: 252 - Chapter 14 • Web Resources
Graphs:
This Graph shows the number of HTTP requests made by Vusers
to the Web server during each second of the load test scenario run.
Throughput Graph - Pag: 261 - Chapter 14 • Web Resources
Graphs:
This graph shows the amount of throughput on the server
during each second of the load test scenario run. Throughput is measured in
bytes or megabytes and represents the amount of data that the Vusers received
from the server at any given second.
Q29) Relation between
Available Bytes and Committed Bytes?
A) inversely
proportional
Q 30) Performance testing
is one of the type of the non-functional testing comes under
A) White box testing
Q31) Which of the following
is not supported scripting languages for loadrunner?
A) .NET (
selected from the set of options provided here). Check the supporting languages
as the options might change.
Q32) You are running a 3
–tier web application with which component must the load generator
communicate?
A) Controller
Q33) Example of conceptual
goal statement?
A) The application’s
update function should still work under heavy load
Q34) What term defines the
end to end measurement of time when one (or) more steps are completed?
A) Transaction
Q35) Which parameter type
will always have the value of one when replayed in Vugen?
A) Group Name
Q36) What must you do
before attempting to automatically correlate after recording?
A) play back the
script at least one time
Q37) Which is used for
executing the scenarios in the controller?
A) Load Profiler is
used to execute the scenarios in the controller
