Oracle 1Z0-134 Sample Questions:

01. Which WebLogic Server tool do you use to create a new domain or extend an existing domain by applying a template?
a) The Administration Console
b) The Configuration Wizard
c) The Domain Template Builder
d) Node Manager
 
02. During a planned maintenance window the Administration Server of a production domain is shut down. An operator then needs to start one of the Managed Servers.
How can the Managed Server start while the Administration Server is unavailable?
a) It contacts another running Managed Server in the cluster and downloads the current domain configuration from that peer instead of from the Administration Server.
b) It automatically promotes itself to act as the Administration Server for the domain.
c) It starts in Managed Server Independence (MSI) mode, using its locally cached copy of the domain configuration.
d) It cannot start at all until the Administration Server is brought back online.
 
03. An application's schema changed after a table was altered, and cached prepared statements on pooled connections now reference a stale column layout.
Which data source operation clears these cached statements without shutting the data source down?
a) Clear Statement Cache
b) Reset
c) Suspend
d) Shrink
 
04. You are reviewing how WebLogic Server decides whether an authenticated subject may access a protected resource, using security roles and security policies.
Which two statements correctly describe how roles and policies work?
(Choose two.)
a) A security role is computed dynamically at runtime by the role mapping provider, typically from the subject's group membership.
b) A security policy binds a resource to the roles or principals allowed to use it, and the authorization provider evaluates it to decide access.
c) Security roles are permanently assigned to individual users at account creation time and are stored directly with the user's entry in embedded LDAP.
d) The auditing provider grants the required roles automatically whenever the authorization policy cannot be evaluated.
e) A security policy stores the user's password hash and is consulted by the authentication provider during login.
 
05. Two applications share the same self-tuning thread pool. During peak load an interactive, latency-sensitive application must be prioritized so it responds quickly, without permanently starving a background batch application of threads.
Which configuration best meets this goal?
a) Put a capacity constraint on the interactive Work Manager so that its excess requests are queued and eventually rejected rather than executed.
b) Give the interactive work a max-threads-constraint sized to the entire pool so that it can seize every available thread whenever it becomes busy.
c) Raise the min-threads-constraint on the batch application's Work Manager so that a larger floor of threads stays permanently reserved for it.
d) Give the interactive requests a response-time request class with the target latency, so the self-tuning scheduler allocates threads to meet it.
 
06. A JMS service is pinned to a migratable target. It must remain active on some member of the cluster at all times — even while its user-preferred server is down — and you do not want it to move back automatically when the preferred server later returns.
Which service-migration policy best matches this requirement?
a) Whole-server migration
b) Auto-Migrate Failure-Recovery Services
c) Auto-Migrate Exactly-Once Services
d) Manual service migration only
 
07. From your workstation you can reach a running Administration Server without any problem. You use Node Manager to start a Managed Server on a remote host. Node Manager launches the server's JVM, but the server never reaches the RUNNING state, and its log shows it cannot connect to the Administration Server to download its configuration.
What is the most likely root cause?
a) From the remote host, the Managed Server cannot reach the Administration Server's configured address and port, so it cannot retrieve its configuration.
b) Node Manager was never enrolled for the domain on the remote host.
c) The remote host is running the script-based Node Manager instead of the Java-based version, so it is unable to hand the downloaded configuration to the started server.
d) The Managed Server must be started in the ADMIN state before it can reach RUNNING.
 
08. Before opening a newly patched Managed Server to end users, you want it to accept only administrative and internal traffic so you can validate its deployments.
Which action achieves this?
a) Start the Managed Server in the RUNNING state and rely on the firewall to block users.
b) Start the Managed Server in the ADMIN state.
c) Suspend the Managed Server immediately after it reaches RUNNING.
d) Start the Managed Server in the STANDBY state.
 
09. Weeks after an incident, you need to review the historical harvested metrics and captured events that WLDF recorded on a Managed Server, and export them for offline analysis.
Which WLDF components support retaining and later retrieving this historical data?
a) The Archive persists the harvested metrics and captured events, and the Data Accessor retrieves them, via the console or WLST, for analysis.
b) The diagnostic image, which retains a rolling history of every harvested metric and captured event so you can replay the full time series weeks later.
c) The edit session, which caches metrics until they are activated.
d) The Node Manager log, which stores all WLDF metrics.
 
10. In an online WLST session you invoke startEdit(), create a new JDBC data source, and then call save(). A colleague monitoring the running Managed Servers reports that the new data source is not yet in effect.
Which action makes the pending changes take effect on the running servers?
a) Call validate() to push the saved changes directly into the server runtime tree
b) Re-run save() with a force option to propagate the changes to the running servers
c) Call activate() to commit and distribute the saved changes to the servers
d) Call stopEdit() to release the edit lock, which then applies the pending changes
