BConfigure a dedicated WebLogic Server for each application
CConfigure a separate node manager for each application
DConfigure a separate cluster for each application
Consider an existing nondynamic cluster that is currently hosting many libraries, applications, and data sources. You need to scale out this cluster to include a new server. You provision the domain on a new machine.
What are the two ways to create this new server in the domain configuration? (Choose two.)
AUse the Configuration Wizard to add a new server to the cluster.
BUse pack and unpack to copy an existing server in the cluster.
CUse the Administration Console to add a new network channel to the cluster.
DUse the Administration Console to clone an existing server in the cluster.
Which two statements are characteristics of the Reconfiguration Wizard? (Choose two.)
AYou can upgrade any domain that was created using WLS 9.2 and above
BThe Reconfiguration Wizard allows you to change the domain mode
CThe Reconfiguration Wizard allows you to select a different Java JDK
DThe Reconfiguration Wizard does not allow the reconfiguration of JDBC data sources
EYou can upgrade only a domain which is running WLS 10.3.x or later
As the technical lead for your project, you have been asked to recommend a new solution to handle frequently increasing loads on your applications. The
WebLogic 12.1.2 domain currently runs with two clusters of three servers with request being filtered and passed by a proxy server that users the round ""robin algorithm.
However, the load sometimes exceeds the maximum capacity of all these servers combined but your domain lacks in scalability.
What is the best implementation solution?
AAdd a third cluster and spread existing server instances across the clusters.
BModify the proxy server load balancing algorithm to weight based.
CConfigure dynamic clusters and specify the number of server instances you anticipate needing at peak load.
DTune work managers to optimize work.
EReplace the software load balancer with a hardware load balancer.
When creating a dynamic cluster, you have multiple options concerning how dynamic servers are distributed across machines in your domain. Identify three supported configurations. (Choose three.)
AUse a single machine.
BUse all machines in a subnet.
CUse all machines in the domain.
DUse all percentage of machines in the domain.
EUse all machines whose names match an expression.
You plan to install WebLogic Server by using the generic JAR installer in silent mode.
What are two ways to create the required response file? (Choose two.)
AFirst install or deinstall graphically. There is an option to save a response file.
BUse the sample response file in the installation documentation as a template.
CFirst run the Repository Creation Utility. There is an option to save a response file .
DThe response file is not required. You can answer questions interactively at the command line.
EThe genetic JAR installer does not have a silent mode, so you do not need a response file when using this installer.
Your domain consists of 30 servers. You are using the Administration Console.
Which is the quickest way to identify the servers that are in a Failed health state?
AUse the Filter button from the domain's Monitoring > Health tab.
BUse the Monitoring > Health tab for each server in the domain.

You are using WebLogic Server Diagnostic Framework (WLDF) Instrumentation in a system diagnostic module. The Dye Injection monitor is enabled. You know the diagnostic context ID of the request you are Interested in that was processed by several. You are looking through the messages in the server log file of several.
Which statement is true?
AYou need to look at the Events Data Archive. Server log files do not contain WL DF context IDs
BYou need to look at the Harvested Data Archive. Server log files do not contain WL DF context IDs.
CYou need to look at the domain log file. Only the domain log file contains WL DF context IDs.
DYou can search the server log file for the context ID. Any message that was written to the log IDs during that request will contain the context ID.
EYou need to translate the context ID into the corresponding transaction ID, which is the only ID in server log file entries.
You are deploying a web application called inventory.war. It has been installed and has the State of "Prepared". It is targeted to the Managed Server named managed1. The web application's context root is /inventory and the starting page is index.jsp.
However, you want to test the application before allowing end users access to it. In the administration console, you select inventory.war, and then select Start and "Servicing only administration requests."
In your web browser, you need to enter a host and port followed by /inventory/index.jsp.
Which host and port would you use?
Amanaged1 host and port
BAdministration Server host and port
Cmanaged1 host and Administration port
DAdministration Server host and Administration port
You are creating and configuring a cluster by using the administration console. Which two statements are true? (Choose two.)
AAll servers that will be part of the cluster must be created before the cluster is created.
BYou must pick the cluster messaging mode.
CEven though you create a non-dynamic cluster, you can change it to a dynamic cluster later.
DOnce the cluster is created, you cannot change its messaging mode.
EThe administration console does not provide a way to manually migrate singleton services. It must be set up to be done automatically or by using WLST.
One Managed Server that is part of a large domain throws java.lang.OutOfMemory errors (OOM) occasionally.
You have been monitoring this server with the jvisualVM tool but that didn't help because the issue occurs infrequently and not a specific scenario. So you decided to force the server to dump the heap memory as soon as an OOM gets thrown in order to analyze the dump file later.
How do you modify the Java HotSpot startup command to enable this feature and save the dump in the directory D:\hprof-dumps?
