Apache ZooKeeper is a software project of a distributed coordination service to manage a large set of hosts. Coordinating and managing a service in a distributed environment is a complicated process, and Apache ZooKeeper solves this complex issue with its simple architecture and API. ZooKeeper also allows developers to focus on core application logic without worrying about the distributed nature of the application. It plays a role to provide operational services for a Hadoop cluster. Our Apache ZooKeeper Online test is created & validated by experienced Subject Matter Experts (SMEs) to assess Apache ZooKeeper skills of candidates as per industry standards.
The Online Apache ZooKeeper test helps recruiters and hiring managers to evaluate the expertise of candidates in the field of Apache ZooKeeper. The test enables employers and recruiters to identify potential prospects by evaluating working skills and job readiness. For this reason, the emphasis is laid upon evaluating the knowledge of applied skills gained through real work experience, rather than theoretical knowledge.
The Apache ZooKeeper assessment test helps to screen for the following:
1. Experience in Apache Zookeeper software.
2. Knowledge of clusters, nodes, ZNodes in Zookeeper.
3. Knowledge of interaction with the distributed applications.
4. Experience in interaction with Server applications and client applications.
By generating a detailed report for each candidate, our Apache ZooKeeper test provide the analytical data which expedites and improves the hiring process. To make you aware of the candidate's experience, we have introduced a new feature called candidate feedback module in our Apache ZooKeeper pre-employment test to ensure that the candidates have an excellent experience while attempting the test.
The online Apache ZooKeeper test may contain MCQs (Multiple Choice Questions), MAQs (Multiple Answer Questions), Fill in the Blanks, Descriptive, Whiteboard Questions, Audio / Video Questions, LogicBox (AI-based Pseudo-Coding Platform), Coding Simulations, True or False Questions, etc.
Two-phase commit (2PC) protocol is a distributed algorithm that is used in Zookeeper to coordinate all the processes that participate in a distributed transaction. Analyze the given statements regarding the 2PC protocol and select the correct option.
Statement A: 2PC protocol consists of three phases and in the first phase, coordinator nodes ask all the participating processes to prepare and vote to either commit or abort the transaction.
Statement B: If all participants voted for commit, it commits the transaction; otherwise, it aborts it. It finally notifies the result to all the participants.
