Sample answers to six interview questions about the WebLogic portal
Here are some examples of how to answer six different WebLogic portal interview questions:
1) What is the meaning of WebLogic?
At the start of your interview, a possible employer might ask you to explain what WebLogic is. They might do this to see how well you understand servers and other tools for programming in general.
Example: “WebLogic is a server that was made by Oracle. It could be either a J2EE application server or an HTTP web server. WebLogic can work with many different databases, like Oracle and DB2.”
What’s the difference between a website and a portal?
The people in charge of hiring you might ask you to explain how different pieces of technology work together. This is so they can see how well you can explain complicated ideas in easy-to-understand language.
Example: “A website is a group of web pages that are usually run by the same person or group. A portal is a type of website that brings together information from different websites run by different groups and puts it all on one site. For example, a company could make a portal that pulls news stories from different sites and puts them all on one site.”53 Questions to Ask at an Interview for Weblogic Portal (With Example Answers)
How do WebLogic-managed servers talk to each other?
Employers who want to hire tech pros might want to make sure that the people they interview know how the different parts of WebLogic fit together. When answering these kinds of questions, try to explain not only how these tech parts work together but also why that way of talking works.
Example: “Managed servers in WebLogic talk to each other using the T3 protocol. The T3 protocol makes communication very efficient because it gets rid of the need for networks to use different protocols to talk to each other. This also means that the T3 protocol reduces the size of packets and uses less OS resources than some other protocols.”
4. What’s the difference between skins and skeletons?
This kind of question checks how well you know how different parts of a website work. An employer who wants to hire WebLogic experts might want to know that you understand both the front-end and back-end of websites.
Example: “The edges of portals are made of skeletons. On the other hand, skins, like style sheets, can change how a portal looks without changing how it is built. When you change a skeleton, the way your portal is set up changes. When you change a skin, you change things like font colours and sizes that end users usually pay more attention to.”
5. Tell me about WebLogic SSL.
The person in charge of hiring you might ask you about how safe WebLogic is. Employers can use these kinds of questions to make sure you know how to use authorization systems well and keep their private information safe.
Example: “SSL stands for Secure Sockets Layer. SSL makes a safe connection between two applications so that each one can check the other’s identity. It also encrypts the data sent between the two applications so that only authorised users can see this potentially sensitive information.”
6. Why is it helpful to put things in groups?
Employers may ask you to explain what’s good about each part of WebLogic. Usually, their goal is to see how well you understand not only how to do different computer tasks with WebLogic but also why these tasks are important.
Example: “Putting things in groups helps in three main ways. Clustering makes it easier to divide the work between the servers, which is one of its benefits. Another benefit is that it is easy to add more servers to a cluster while keeping the ones you already have running smoothly. Last, clustering helps WebLogic keep a high level of availability, which means that its servers are more likely to keep running without any problems.”
