Question No : 1


An organization needs to deploy Qlik Sense Enterprise on Windows to meet several security requirements:
• Users in the 'Developers' group should be able to create apps;
• Users with ContentAdmin and RootAdmin roles should be able to create apps;
• No other users should be able to create apps.
Which two actions should the system administrator take to meet these requirements? (Select two)

정답:
Explanation:
By default, Qlik Sense security rules allow users to create their own applications (with the proper license to use, of course). So an important step is to disable the existing default rule.
The second step is to create a rule with the desired constraints. You will allow in the new rule that only users who have the specified rules (or groups) can create them.
So in this rule you take advantage of the existing Security Rules of: RootAdmin and ContentAdmin and add a condition to the "Group" Developers. This group is previously tied to the user's registration via User Directory connections on a Windows server with Active Directory enabled (LDAP).

Question No : 2


A system administrator imports an app into Qlik Sense Enterprise. The app was developed with Qlik
Sense Desktop. The app reload fails.
What is causing this error?

정답:
Explanation:
One of the characteristics of application imports in Qlik Sense Enterprise is that it does not overwrite connections of the same name. And that's great! Imagine the problem that would occur if this happened. Each time you perform a new application import, be sure to check the operation of all connections. As much as they are registered, you may have to change parameters, folder paths, and so on.
And keep an eye out for those with the same name, you may need to rename the connections from the
new application to another.

Question No : 3


A system administrator has a Qlik Sense environment with a Central Node and a Scheduler Node. One of the applications loads data that is located in the SalesERP folder on drive F: on the central node. The system administrator creates a folder data connection and sets Name = "Sales_ERP" and Path = "F:\SalesERP". When the reload task is first performed, it fails.
What is the cause of the error?

정답:
Explanation:
Port 4747 refers to Qlik engine communication (Engine Service). If you were in trouble, users wouldn't even get the error mentioned to play.
How the folder is on the D drive:\ server, there is no need to share the folder on the network.
There is no point in saying that the scheduler node service is limited.
The possible cause is that the newly created connection has some rule that prevents users from using or a release rule has not yet been created.

Question No : 4


A company had only one server and later made an additional Qlik server available and configured it as a scheduler node. There is a recharge task that occurs every 30 minutes, every day. When the task is performed, users suffer from poor performance in browsing applications. Then, when analyzing the settings in QMC, the system administrator identifies that the consumption node runs the services: Engine, Scheduler, Repository, and Proxy. The scheduler node runs: Engine, Scheduler, and Repository.
What is the most efficient method for improving performance?

정답:
Explanation:
Regarding the Scheduler service, until the September 2020 version the types were named as: Master
and Slave. As of the November 2020 version the types are named: Primary and Secondary.
Because there are two nodes with the Scheduler service running, it is ideal to direct the loads only to the schedules node and prevent the consumption node from doing so. That's why it's recommended to leave the Scheduler service of the scheduler node as Primary.
Primary (former Master): Sends the afternoon to the Secondary node (old slave);
Secondary (old Slave): Receives the task from the Primary node (old Master) and performs the task;
Primary and secondary: That's when both act on reloading tasks.

Question No : 5


Qlik Sense is deployed in a environment using up-to-the-minute data replication software that keeps all storage drives backed up.
A system administrator needs to upgrade the environment to the latest version of Qlik Sense Enterprise.
Which three items should the administrator back up? (Select three)

정답:
Explanation:
First, be ware of the official issue that appears on Qlik's website. It doesn't have the option of "Shared persistence file share" and this is as crucial as the other two options!
Second, this is a difficult question to Answer with a few words. Just keep in mind that for a service to return to work in the event of a breakdown you will need the applications used, connection certificates and the database that contains information about the system and meta data of the applications. Everything else can be reinstalled from scratch.

Question No : 6


A system administrator needs to upgrade their environment to the latest version of Qlik Sense Enterprise available. In order for you to have security in this process, you need to perform a backup.
What three items does the system administrator need to make sure to back up before continuing?

정답:
Explanation:
Microsoft Management Console (MMC) is a Windows application that assists in administrative and configuration tasks. It is typically best suited for performing certificate backups. If you are curious, you can on your computer go on: Start - Run - mmc <enter>.
You can learn more about Qlik's recommended backup strategies on this site. https://help.qlik.com/en-US/sense-admin/November2020/Subsystems/DeployAdministerQSE/Content/Se nse_DeployAdminister/QSEoW/Deploy_QSEoW/Backup-and-restore.htm

Question No : 8


Imagine a single server environment that has all services running. At some point users report that applications are very slow, all of them. The system administrator works remotely on support and realizes that there is actually a problem occurring.
Due to performance issues, the system administrator has difficulties accessing the QMC. Additionally you receive an email stating that the server's memory ram has reached its limit.
What step can the system administrator take to check what is happening in the environment?

정답:
Explanation:
I believe it is important to comment on each response. http://<server.domain.com>/engine/performancecheck. This address doesn't exist! http://<server.domain.com>/engine/healthcheck returns content in JSON that can be queried and handled via some API. It is a super useful feature that demonstrates open applications, active users, available memory, but will bring to the system administrator what he already knows: memory is high consumption. You still need to understand why this happened. https://<server.domain.com>/qmc/audit leads to the audit page for verification of application accesses, users, streams, and so on.
%ProgramData%\Qlik\Sense\Log\Engine. This folder can Answer questions of what is happening. By default it stores all events considered a "WARNING" which is when there is something severe going on. If by chance a developer has released a very heavy expression or an application is in trouble, this log may be the Answer you are looking for for that moment. Then, after unburdening the server, pay special attention to what is described there, as it will require a deeper investigation of the problem. You can learn more here.

Question No : 9


Let's say you don't have remote access to the Windows server (RDP) where Qlik Sense is installed, but you have Root Admin rules in QMC. So how can you make a copy of the Qlik Sense file, which your
colleague created to make some quick changes using Qlik Sense Hub?

정답:
Explanation:
In the QMC apps tab, when you select an application and "duplicate it," the copy automatically goes to your Workflow, where you can make the necessary changes to the copy if you have its accesses through the Qlik Sense Hub.
A user and password to access Qlik Sense, even if it is with Admin rules do not guarantee that you will be able to access the server via RDP connection. For access via RDP it is necessary parameterizations on the Windows server, such as: to be part of the workgroup that has remote access, among others.
If you know the access address of the server and it is configured to receive the connection, you can access Qlik Sense through your browser, there is no need to perform an RDP connection.

Question No : 10


A developer needs to share JavaScript libraries to be used with several extensions. All extensions need to use the same version of the libraries.
Which option should be used?

정답:
Explanation:
The AppContent folder is where apps are stored, usually in %ProgramData%\Qlik\Sense\Repository\AppContent\<App ID>. And this is definitely not a suitable place to share libraries in Java.
File share would be in the sense of sharing a folder over the Windows network, which does not make sense, because to be used by extensions the files need to be mapped through a connection via Qlik Sense and not loose somewhere on the file server.
Folder connection could be a good idea in theory, but it is used to perform loads of information when you create an application, such as a spreadsheet in Excel, for example.
Content Library is the right place.
What a lot of people believe is that it is a repository of images, which is not true. It can be used to save any useful file type to an existing application. Content Libraries

Question No : 11


A system administrator needs to automate the Qlik Sense Enterprise upgrade process.
Which syntax should the administrator use?

정답:
Explanation:
The idea is to perform a "silent" installation, for this it is necessary the command "-silent" or just "-s". The following argument of skipstartservices=0 would already be the default, not required.
As other options present syntax errors and it would not be possible to run them or there would be interaction with the user.

Question No : 12


There is a problem to be resolved on the Qlik Sense server. The infrastructure area has told you that there is no system, network, hardware, or process problem that could be interfering with the operation of Qlik Sense.
You then decide to arrive at how scheduled task runs and token allocations are for users to access.
What two tools will you use for this scan? (Choose two)

정답:
Explanation:
Reloads Monitor: displays record data about refills. Reload data is collected from both QMC tasks and open applications in the hub. You can see which updated apps are and details about when, where, and how often they are updated.
Log Monitor: loads and views virtually all available Qlik Sense logs. It gives the possibility to visualize trends and problems in your environment.
And out of curiosity, follows the explanation of the other:
Sessions Monitor: displays log data about users' application sessions.
License Monitor: loads service records to populate charts and tables that cover token allocation, use of login and user passes, and errors and warnings.
Operations Monitor: loads service records to populate charts that cover the performance history of hardware utilization, active users, application sessions, reload task results, and errors and warnings. It also tracks changes made to QMC that affect operations monitor. For more details:

Question No : 13


A task is configured to run at 1:00AM. Historically it is a task that takes around 2 hours to complete. The system administrator realizes that the task is still running in the morning when it should have ended last night.
What is the cause of extended recharge time?

정답:
Explanation:
This type of question has a multitude of different interpretations, but I want you to follow a particular line of reasoning: through elimination it is possible to know the correct Answer , because when we set up a new task in QMC, if we keep the parameter "Max retries" in the pattern, which is zero, the task is no longer executed in the event of error. But now imagine that this parameter has changed. So if there was any changes to the database access credentials as well, the task will try to run that number of times parameterized.
A slight increase in the amount of data would result in a small increase in load. It wouldn't make sense to grow little and take too long.
Drivers for connection to the database do not have, for the most part, automatic updating. That's because it would be a very big security breach. Ideally, the environment will work with a stable, already tested version. These are situations performed manually.
If there was resource restriction in the database for some reason, surely the task would not have been performed from the past times and the symptom is that it stopped working overnight.

Question No : 14


A system administrator needs to schedule a new task for non-working hours in a system with several other tasks. The new task must be scheduled to run at a time when no other tasks are running.
Which two apps should be used find the best time to schedule the new task? (Select two)

정답:
Explanation:
Sessions Monitor loads and displays log data about users' app sessions.
Reloads Monitor loads and presents log data about reloads. Reload data is collected both from QMC tasks and apps open in the hub. You can see which apps are updated, and details about when, where, and how often they are updated.
License Monitor loads service logs to populate charts and tables covering token allocation, usage of login and user passes, and errors and warnings.
Operations Monitor loads service logs to populate charts covering performance history of hardware utilization, active users, app sessions, results of reload tasks, and errors and warnings. It also tracks changes made in the QMC that affect the Operations Monitor.
Sense Connector Logs Analyzer app lets you investigate patterns of activity and errors to troubleshoot
connector performance.

Question No : 15


The Marketing user who should access a stream of the same name receives a message: "An error occurred. Access is denied".
The rule in the stream is:
((user.group!="Sale" and user.group!="Finance" and user.group!="Accounting"))
What is causing this error?

정답:
Explanation:
This issue can confuse even the most experienced. And I'll explain the reason:
It is very common in Qlik Sense Enterprise environments, especially in the first deployment of the client someone create a Security Rule with parameter Resource filter = "Stream_*" for all users, so that everyone can access the new streams as they are created automatically.
And then, when they create a new stream, this type of rule is automatically inherited, giving the impression that by default access to the stream is guaranteed, which is not true.
For a user to have access to a stream, there must be a rule that gives them access permission. According to the issue, the stream rule prevents some groups from going into the Stream, but has no other rules that give the permission themselves.
Another point is confusion about Section Access. The clue is about the error message. When the user does not have access due to Section Access the message is only "Access Denied" and not "An error has occurred. Access is denied". There might even be an error there, but there's a security rule situation that needs to be resolved first.
