About IBM C2180-401 dump
The test consists of nine sections containing a total of approximately 65 multiple-choice questions. The percentages after each section title reflect the approximate distribution of the total question set across the sections.
- Section 1 - Architecture (11%)
- Identify the components and services in a WebSphere Application Server configuration and describe how they are related or interact.
- Design various WebSphere Application Server topologies, for example, flexible management, intelligent management, mixed platform topology, network deployment cells, Liberty collectives, and ODR.
- Analyze appropriate design considerations when architecting topologies to achieve security, scalability, performance and fault tolerance.
- Demonstrate an understanding of how requests traverse various WebSphere Application Server topologies.
- Demonstrate an understanding of the administration activities for a network deployment cell including the flexible management components.
- Identify and describe the components of the WebSphere Application Server Liberty profile.
- Section 2 - Product Installation, Configuration and Maintenance (15%)
- Demonstrate an understanding of the IBM Installation Manager and IBM Packaging Utility and its role in installing, configuring, and maintaining WebSphere application servers and components both locally and remotely.
- Perform a silent installation process for WebSphere Application Server and fix pack installations.
- Perform pre and post installation verification.
- Troubleshoot installation problems.
- Create and manage Full and Liberty profiles.
- Manage nodes in a WebSphere topology, for example, managed, unmanaged nodes, flexible management and network deployment cell.
- Backup and restore configuration including the use of checkpoints.
- Section 3 - Application Management (Assembly, Deployment and Configuration) (9%)
- Explain the structure of enterprise applications, web applications, and business level applications.
- Deploy applications to a WebSphere Application Server environment.
- Configure resources, for example, data sources, JNDI, class paths, J2C providers, as required by an application.
- Use the IBM Rational Application Developer for WebSphere Software or the IBM WebSphere Application Server Developer Tools for Eclipse to examine and manipulate applications.
- Demonstrate an understanding of the administrative tasks required to take an application deployed to the Liberty profile and deploy it in a WebSphere Application Server Network Deployment environment.
- Section 4 - Administrative Tools (14%)
- Illustrate the usage of the Integrated Solutions Console (ISC) and its various tools (e.g., command assistance, runtime messages).
- Use the standard set of command line administrative tools such as wsadmin, profile management and plug-in generation.
- Use the capabilities of the Job Manager tooling including the submission of Liberty profile jobs.
- Use scripting to perform administrative tasks, for example, scripting libraries, ws_ant, wsadmin
- Write, test, and debug scripts by using the IBM Rational Application Developer for WebSphere Software or the IBM WebSphere Application Server Developer Tools for Eclipse.
- Configure or modify a WebSphere Application Server environment by using properties files and/or the monitored directory feature.
- Section 5 - Security configuration and Maintenance (14%)
- Configure user repositories.
- Configure SSL for clients and servers, for example, create certificates, populate trust stores and modify certificate expiration.
- Discuss the implications of resource security settings.
- Implement multiple security domains.
- Apply administrative and application security roles.
