1.What is ATG System Admin?
ATG is a framework that helps in making web applications based on J2EE standards, and is from the Art Technology Group.
2.What is WINS Server and how is it useful?
It is basically a server with the help of which the users can simply make sure of accessing the resources through the name of the nodes in the network rather than using the IP. It can be configured in the system for keeping a track record of IP addresses and node names.
3.How well can you explain the Active Directory concept in the System administration?
When it comes to network security and administration, something that largely matters is nothing but the centralized control of everything. The same can easily be assured through the Active Directory. The nodes which are associated with the server are generally configured with the Active Directory. Generally, they act as controllers for all the domains concerned with the network.
All the settings and the information related to the development is generally stored in the central database. The Directory makes sure that the administrators enable the deployment and policies. Depending upon the nature of the task, it is also responsible for the other tasks that are related to the operating system.
4. What does APIPA stand for?
APIPA means Automatic Private IP Addressing. IT enables users to locate IP addresses when the DHCP servers fail to perform their tasks.
5. What do you know about the Domain controller and how it is significant?
It is also known as a network domain controller and is basically a computer system that is often based on Windows. All the data and the information that is related to the user account are stored on a central database with the Domain controller.
It is also regarded as the central unit for the Active Directory in Windows. It is mainly responsible for matching the authentication details and making sure that the security policies are not getting violated.
6. What is the significance of VOIP?
It is basically an approach that is helpful for enabling users to adopt modern techniques over the traditional infrastructure. It stands for Short for Voice over Internet Protocol which is basically a special type of software and hardware with the help of which users can clearly use the transmission medium which is designed for the telephone calls by delivering the voice packets.
7. What do you mean by Group Policy Objects and how they are significant?
A GPO is nothing but an array of settings that is responsible for ensuring the proper control of the working environment of a user, as well as nodes account. There are policies that are important and GPOs are responsible for the implementation of the same.
In addition to this, a GPO performs another important task and i.e. it redirects the folder options. Generally, the GPOs are of two types and they are Local and Non Local Group.
8. What exactly do you know about a Domain?
Basically, it’s nothing but the logical group of network objects that generally include users, computers, as well as devices among which the Active Directory database is pretty common. In a tree that generally defines how the nodes are connected, there can be multiple domains and each is responsible for the functioning of a specific one.
9. What is the significance of the Sysvol Folder? What are the conditions for creating the SYSVOL Folder in the system?
This Folder is responsible for storing enabling the users to have common access on a domain. Basically, the copy of the server of the domain files is stored in this folder. The users can add more files to it to enhance the accessibility of the domain. There are AD databases that can also be stored in this folder. This Folder can be created if the system Administrator follows the NTFS partition.
10. Tell us something about Windows Deployment Services?
It is useful when it comes to deploying the Systems which run on Windows remotely. It is mainly used for network-based Operating system installation. This is to make sure that the new nodes can be added to the existing network in a reliable manner.
This service lets the users make remote access to the nodes within the network simply and if they are allowed the same.
11.Explain something about the Light-Weight Directory Access Protocol?
The Light-Weight Directory Access Protocol is responsible for the naming of the objects which are under the Active Directory. It is basically the industry standard directory access protocol. Its main aim is to enhance the reachability of the Active Directory.
12.Explain something about the group policy and why does that matter?
The implementation of the specific configurations is implemented for the nodes as well as for the users through the Group Policy. There are GPO’s (Group Policy Objects) which contain the settings of the group policy. They are generally made linked to the sites, units, or with the domains directly.
13. What do you mean by the Lingering Objects in the System?
While performing tasks, there is often a need to erase or to delete the Active Directory from the system. A deleted or an erased Active Directory file can be considered as a Lingering object. They are called Lingering because of their presence when the same is on the Domain Controller.
After creating the system backups, there are changes on the directories and the same is responsible for the creation of the same. There is actually a limit on the backup file and i.e. it should be older than 180 days. All those are older than this, get deleted automatically, and are called Lingering objects.
14. Name the command which you can use to remove the Lingering object? Why is removing them important?
They can be removed easily through the command REPADMIN.EXE. It is basically a console utility command. In case the Lingering objects are not deleted, they can put an extra burden on the system’s Random Access Memory and can create problems such as limited space availability and slow performance.
15.Why is Active Directory Backup important?
It is important mainly due to the proper functionality of the Active Directory Database. Without creating the backup, the system cannot let you work on the older modules and users cannot keep up the pace simply with the registered domains that are essential for performing several important tasks. In case the backup is not created, the troubleshooting process is to be adopted by the users.
16.As a system administrator, what do you think is the more critical factor associated with the hardware components?
Something that is very important about the hardware components is their proper installation, maintenance, as well as replacement. They are actually the essential operations that the users have to perform with the hardware. The most critical one could be the replacement or building of a component.
17.Name one important skill that you think a System Administrator should have?
Well, one thing which is common among all the tasks performed by a system administrator is problem-solving. Thus, he/she should be good in the same and this is one of the essential skills of a system admin.
18. What according to you could be the characteristics of someone administering the System?
A System Administrator should know who to handle the operations related to hardware. He/she must also be good with the software domain. Although they have to work individually, they must know what and when to discuss with others. Gathering information, problem formulation, troubleshooting and managing the technical problems are some of the other important characteristics that an expert should have. Upgrading the systems and reducing the down-time of the servers is also their responsibility. Because they have to take several important decisions quickly, so good decision-making ability is another prime characteristic they must bear.
19. How FAT and NTFS are different from one another according to you?
FAT is basically an old approach and is a file system that was common with the older versions of the Windows. It has a limit on the memory and users are not in a position to run the files that are heavy and of HD quality. Therefore it doesn’t have a wide scope in the present scenario. On the other hand, NTFS is common these days. The best thing about the same is it enables users to have a better command over the files due to better security policies when compared with the FAT. Some of the key features that make it simply the best are Shadowing, Quotas as well as Troubleshooting.
20. What is the difference between dsp and dspel tags?
•The DSP tag is a library of tags which supports runtime expressions, such as suggestions while scripting variables. These tags use an id characterized by name while scripting the variables.
•The DSPEL tag library supports JSTL Expression Language (EL) fundamentals that are assessed during runtime. These tags regularly generate a result entity codenamed by the var attribute.
•For customized tags we need to write the properties file and a class file to define the purpose. We should also include a tag file with extension .tld, which means tag library definition, and in the droplet consisting of the path of tag uri<% tag uri..%>
•For example we can write a custom tag to compute the shipping charge with promotion and save it and pull it as & when required.
21. What are the two methods of component?
These are the two methods of component: setters & getters. These components help the setter to keep their data in private while exposing their article to any public repositories.
22. What do you mean by item descriptor?
Item descriptors can be detailed with the help of SQL Repository. For example, each database table has a unique repository item descriptor. Sometimes multiple tables are joined into a single item descriptor. Since ATG supports Java collections, hence we can store a list, map or arrays. ATG repositories allow one-by-one, one-many, many-many relationships.
23. How is a shopping cart implemented?
In ATG it’s very simple as we need to use the ShoppingCartFormHandler, available amongst form handlers.
24. What are the main formhandler to be used for shopping carts?
Basically ShoppingCartFormHandler & CartModifierFormHandler are the two main formhandler that are being used while making a shopping cart.
25. What are the benefits of DAF?
•It is generally used to maintain a large pool of data.
•Repositories are included in it which help to pull data anywhere during building of an architecture.
•It can script any object of any type which is requested for the db.
•Dynamo messaging generally uses patch jms and bay for better efficiency.
26. What is ATG DPS & its elements?
ATG Dynamo personalization system is abbreviated as ATG DPS. It works on the basis of the user’s Profile Data and the rules have been fabricated to deliver the right content as per the request of the user. There are basically three key elements are associated with ATG DPS which are as follows:
•User Profile Management: when a visitor approaches the website for the first time, the user is allowed to create their own profile. After they submit their customized data, DPS stores the visitors profile in its database repository. This repository best describes the preferences and characteristics of the user. Accordingly the content is customized and shown to the visitor.
•Content Targeting: Content is customized for a specific user at a specific time in a specific context and set of rules.
•E-mail Targeted: DPS includes targeted mail services not only for delivering, but customizes in composing the mail too. Scenarios can be conveyed to the user too. It sends a confirmation mail to each and every single user after they register on the site. It also sends notifications to all users who haven’t logged in to the site for long and their account might be shut down soon.
27. Mention the extent of Dynamo Components?
The extent of Dynamo Components are as follows:-
•Session
•Request
•Worldwide being the default scope.
28. What do you mean by scenarios?
Scenario predicts and tracks the activities of the website visitors and acts accordingly, for e.g., customizing the content of the page visited and offering exclusive promotions on offer, or sending targeted messages through an e-mail.
29. What do you mean by pipeline?
It’s simply a variant of Servlet Pipeline. In an ATG pipeline the order of Programs are implemented in a sequence. It initiates with the DynamoHandler which adds the definitive dynamo request and responds accordingly. The lists of servlets seen are dependent on the module being used. This is how Dynamo Application Server adds more servlets to its pipeline.
30. Is DAS applicable for high volume or low volume traffic?
Dynamo Application Server (DAS) is generally used to manage high volumes of traffic.
31. What are the problems faced with ATG’s performance?
know that issues come in all shapes and sizes, which means that the performance of the task is not going as expected, which was previously observed to be functioning smoothly. Issues include CPU utilization, sluggish responses, database activity of high levels, long running SQL queries, slow CA deployments are some of the few.
32. Which IBM products are used with ATG?
IBM’s Web Sphere Application Server is of great use to enhance the performance of ATG. Apart from Eclipse IDE, which is an open source platform used for developing web applications.
33. What do you understand by derived properties?
Derived properties means enabling of extracting the property value from one repository article to another repository article or from another property to the same repository article.
