C1000-174 Sample Questions & Answers
Administering the environment, from profiles to the console, is weighted most, alongside building multi-node topologies for high availability, installing and updating the server, SSL-based security domains, performance tuning, and modernizing older applications.

- Question 1Beginner
Install and Update the Environment · Perform post installation verification
While verifying a new installation of WebSphere Application Server using the
ivt(Installation Verification Tool), the administrator receives a failure message. Which log file should be the PRIMARY source to investigate the specific error details generated by theivtutility?Show answer & explanation
Correct answer: B
The Installation Verification Tool (IVT) logs its specific activity and errors to the
ivt_client.logfile located in the profile's logs directory. WhileSystemOut.logmight show server-side processing,ivt_client.logis the specific log for the verification tool's execution. - Question 2Beginner
Install and Update the Environment · Apply maintenance to the product
True or False: When applying a Fix Pack to WebSphere Application Server ND using IBM Installation Manager, you must stop all running WebSphere processes related to the installation being updated, including the Deployment Manager and Node Agents.
Show answer & explanation
Correct answer: A
This is True. IBM Installation Manager modifies the core product binaries. Therefore, all java processes (Servers, Node Agents, DMGR) using those binaries must be stopped to release file locks and ensure the update is applied correctly to the installation root.

Install and Update the Environment · Migrate application servers
A team is preparing to migrate a large Network Deployment cell. They have decided to use the
WASPreUpgradecommand. Which of the following parameters are valid and commonly used when running this command? (Select TWO)Show answer & explanation
Correct answers: C, D
WASPreUpgradeuses-machineChange(true/false) to indicate if the migration is crossing machine boundaries, which affects how node paths are handled.WASPreUpgradeuses-keepDmgrEnabledto determine if the old Deployment Manager should remain active/enabled during the migration process. - Question 4Intermediate
Create a High Availability Configuration · Configure distributed session management for high availability and failover scenarios
An administrator is designing a high availability session management strategy for a cluster of 4 servers. The requirements state that session data must be preserved even if multiple servers fail, and the solution must minimize the performance impact on the database. The administrator decides to use Memory-to-Memory replication. Which replication topology is most appropriate to distribute the session replication workload across all servers in the cluster evenly?
Show answer & explanation
Correct answer: B
In Peer-to-Peer mode, every server in the cluster replicates its sessions to other servers in the cluster. This eliminates the single point of failure and distributes the replication workload, fulfilling the requirement. Client/Server mode would require dedicated session servers. Database persistence was ruled out by the performance requirement.

Create a High Availability Configuration · Configure and manage the HTTP server and the web server plug-in for high availability
A cluster of WebSphere servers has been scaled out by adding two new nodes. The administrator has federated the nodes and added cluster members. However, users report they cannot access the application on the new nodes via the IBM HTTP Server (IHS). What critical step has likely been missed regarding the web server configuration?
Show answer & explanation
Correct answer: B
The
plugin-cfg.xmlfile contains the routing information that the Web Server Plug-in uses to determine which servers handle requests. When the topology changes (adding nodes/members), this file must be regenerated (to include the new members) and propagated (copied) to the IHS server so it knows about the new destinations. - Question 6Advanced
Create a High Availability Configuration · Create a multi-node topology and appropriate high availability model
In a very large Network Deployment cell with over 100 application servers, the administrator observes high CPU usage on the Deployment Manager due to frequent core group communication. To resolve this and improve scalability, what architectural component should be configured to aggregate communication between core groups?
Show answer & explanation
Correct answer: B
A Core Group Bridge is used to connect multiple core groups. In very large cells, splitting servers into multiple core groups reduces the mesh communication overhead. The Bridge facilitates communication between these isolated groups, improving DMGR performance and overall cell scalability.
