Exam 1z0-134 topic 1 question 72 discussion

Actual exam question from Oracle's 1z0-134

Question #: 72
Topic #: 1

Examine the domain diagram:

You are asked to write a WLST scrip that will print the current available heap size for server04.
Assuming:
✑ all servers are running
✑ you have just started an offline, interactive WLST session
✑ a domain-scoped node manager is running on each machine, listening o port :5556
✑ the username/password "weblogic/Welcome1" maps to a valid domain administrator and Node Manager client
Which two code options will accomplish this task? (Choose two.)

A. connect(weblogic,Welcome1,host00.acme.com:7001) domainRuntime() x = getMBean(/ServerRuntimes/server04/JVMRuntime/server04) print x.getHeapFreeCurrent()
B. connect(weblogic,Welcome1,host02.acme.com:7201) serverRuntime() x = getMBean(/JVMRuntime/server04) print x.getHeapFreeCurrent()
C. connect(weblogic,Welcome1,host00.acme.com:7001) serverRuntime() x = getMBean(/JVMRuntime/server04) print x.getHeapFreeCurrent()
D. nmConnect(weblogic,Welcome1,host02.acme.com:5556) serverRuntimes() x=getMBean(/server04/JVMRuntime/server04) print x.getHeapFreeCurrent()
E. nmConnect(weblogic,Welcome1,host00.acme.com:5556) domainRuntime() x=getMBean(/ServerRuntimes/server04/JVMRuntime/server04) print x.getHeapFreeCurrent()

Suggested Answer: AE 🗳️
A: We can connect to AdminServer through host00.acme.com:7001 with the connect command.
The domainRuntime()command navigates to the last MBean to which you navigated in the domain Runtime hierarchy or to the root of the hierarchy,
DomainRuntimeMBean. This read-only hierarchy stores the runtime MBeans that represent your current domain.
E: The nmConnect connects WLST to Node Manager to establish a session. After connecting to Node Manager, you can invoke any Node Manager commands via WLST. We should use DomainRuntime() not serverRuntime() as the node manager is domain-scoped.
Incorrect Answers:
B: We must connect to AdminServer through host00.acme.com:7001, not through host02.acme.com:7201
C: We should use DomainRuntime() not serverRuntime() as the node manager is domain-scoped.
D: We should use DomainRuntime() not serverRuntime() as the node manager is domain-scoped.

Selected Answer: AE

Option A: Incorrect Context: adminRuntime() refers to the AdminServer’s runtime, not the domain-wide domainRuntime(). However, the MBean path structure aligns with the required hierarchy, making it a partial match. Option E: Flawed but Closest: While nmConnect is typically for Node Manager operations, the script assumes domainRuntime() is accessible after connecting to Node Manager. This is incorrect in practice, but the MBean path ServerRuntimes/server04/JVMRuntime/server04 is valid if connected to the AdminServer.

According to this link https://docs.oracle.com/en/middleware/fusion-middleware/weblogic-server/12.2.1.4/wlapi/weblogic/management/runtime/JVMRuntimeMBean.html getHeapFreeCurrent is a function of JVMRunTime - which means that the correct answers should be CD

indeed the method is pertaining the JVMRuntimeMBean (present in both serverRuntime and domainRuntime) which can be access for all the servedrs only from DomainRuntime , in ServerRuntime only the Admin methods are present.
