A web application is hosted on an application server that receives HTTP requests from a third party application named myApp. The URIGroup mapping for this application is called default_host_myApp.
The development team asks a system administrator to configure the HTTP plug-in to prevent routing requests to any application server except server1.
The following exhibit shows the parts of the plugin-cfg.xml file that are relevant for myApp.
The UriGroups for other applications are not shown in the exhibit.
What should the administrator do to the plugin-cfg.xml file to ensure that requests for default_host_myApp URIGroup are routed only to machine1?
A. Delete the UriGroup tag for default_host_myAppDelete all of the tags within the
UriGroup tag
B. Delete the Server tag for CloneId="b20000002"Delete all of the tags within the Server tag
C. Edit the LoadBalanceWeight for server1 to 20Edit the LoadBalanceWeight for server2 to
2
D. Delete the VirtualHostGroup tag for default_hostDelete all of the tags within the
VirtualHostGroup tag
正解:B
質問 3:
A performance test team was testing the capacity of concurrent users of a web application deployed on a multi-processor server. While testing 250 concurrent users, the administrator discovers connections to the database are failing.
In response, a system administrator increased the connection pool to the maximum limit which the database allows and increased the prepared statement cache size. The test passed, but the application response time was slower.
How should the system administrator tune the data source properties to improve the application response time?
A. Decrease connection pool reap time.
B. Decrease the prepared statement cache size.
C. Change connection pools purge policy.
D. Decrease number of free pool partitions.
