Question 1

GridGain works with a GridTask, which specifies how to handle the main unit of work of the interface type:-a) Gridb) GridGainc) GridJobd) All of the mentionedAnswer: cExplanation: Underneath the hood, GridGain works with a GridTask, which specifies how to handle the main unit of work of the interface type GridJob. 5. When you call the method on the service with the @Gridify annotation pointing to this GridTask implementation, it stops execution of method and loads an instance of this implementation.a) Trueb) FalseAnswer: aExplanation: The parameters, as passed to the method with the annotation, are passed to: split(int i, final GridifyArgument gridifyArgument), which is used to dole out GridJob instances.advertisement/**/    var adpushup = adpushup || {};    adpushup.que = adpushup.que || [];    adpushup.que.push(function() {        adpushup.triggerAd("fdd9bf87-4faf-4493-82b4-e5538b31931a");    });/**/6. When using GridGain stem mostly from the fact that what you develop on one node can’t always automatically work on another node with no additional configuration.a) Trueb) FalseAnswer: aExplanation: The parameters, as passed to the method with the annotation, are passed to: split(int i, final GridifyArgument gridifyArgument), which is used to dole out GridJob instances.7. GridGain lets you start up nodes using the startup script in the:-a) etcb) optc) bind) all of the mentionedAnswer: cExplanation: GridGain lets you start up nodes using the startup script in the bin directory of the distribution.  advertisement/**/    var adpushup = adpushup || {};    adpushup.que = adpushup.que || [];    adpushup.que.push(function() {        adpushup.triggerAd("21eae76a-c83f-42b0-aec5-01d590a53f37");    });/**/8. To hoist a grid node into existence.a) GridLoaderb) GridLoadc) Gridd) GridGainAnswer: aExplanation: The GridLoader’s job is to hoist a grid node into existence.   9. When you use the script that comes with the distribution is the class:-a) GridCommandLineb) GridCommandLineLoaderc) GridCommandd) All of the mentionedAnswer: bExplanation: The one that gets started when you use the script that comes with the distribution is the class GridCommandLineLoader.advertisement/**/    var adpushup = adpushup || {};    adpushup.que = adpushup.que || [];    adpushup.que.push(function() {        adpushup.triggerAd("90f55663-effd-4105-b1e7-29d86b526544");    });/**/ 10. A GridLoader instance is responsible for many things such as:-a) GridFactory.startb) GridFactory.stopc) All of the mentionedd) None of the mentionedAnswer: cExplanation: A GridLoader instance is responsible for many things, not the least of which is correctly calling GridFactory.start and GridFactory.stop.11. GridFactory.start can take as its first parameter a:-a) GridConfiguration objectb) Spring application contextc) All of the mentionedd) None of the mentionedAnswer: cExplanation: This GridConfiguration object is what tells GridGain what is unique about a given node and the grid’s topology. By default, it uses $GRIDGAIN HOME/config/default-spring.xml, which, in turn, does things such as load a Grid object and configure user parameters about a specific node.12. The file which enables you to tell GridGain about which GridTask classes are deployed:-a) gridgain.xmlb) gridgain.htmlc) grid.xmld) gridify.xmlAnswer: aExplanation: gridgain.xml file, which is optional, enables you to tell GridGain about which GridTask classes are deployed.  13. Instances of the ApplicationContext can be injected into the various GridGain class instances (GridTask, GridJob, and so forth) using GridGain:-a) @Gridb) @GridGainc) @Gridifyd) None of the mentionedAnswer: dExplanation: Instances of the ApplicationContext can be injected into the various GridGain class instances (GridTask, GridJob, and so forth) using GridGain @GridSpringApplicationContextResource annotation.  14. This is the default implementation. It is used when you run gridgain.sh or gridgain.bat.a) org.gridgain.grid.loaders.cmdline.GridCommandLineLoaderb) org.gridgain.grid.loaders.servlet.GridServletLoaderc) org.gridgain.grid.loaders.jboss.GridJbossLoaderd) org.gridgain.grid.loaders.weblogic.GridWeblogicStartupAnswer: aExplanation: org.gridgain.grid.loaders.cmdline.GridCommandLineLoader This is the default implementation. It is used when you run gridgain.sh or gridgain.bat.  15. This is likely the second most useful implementation. It provides a servlet that bootstraps the GridGain instance inside any web container as a servlet.
