4. A parallel service group named websg is online on sym1, sym2, and sym3 in a three-node cluster. The service group contains a critical NIC resource and a non-critical Phantom resource.

12. What occurs when an administrator runs the command hastop -all -force?
  • a. LLT and GAB are brought offline on all cluster nodes.
  • b. Applications are brought offline, and the cluster stops.
  • c. HAD and hashadow processes are stopped on all cluster nodes.
  • d. All applications are forcibly brought offline, but the cluster remains online.
13. What is the default service group type when creating a new service group to bring an application under Symantec Cluster Server control?
  • a. Failover
  • b. Hybrid
  • c. Load Balancing
  • d. Parallel
14. An application identified for clustering by the system administrator is hard-coded so that it must be installed in /usr/local/app.

What are two considerations for clustering the application? (Select two.)
  • a. The application could be clustered by mounting a file system from the shared storage on /usr/local/app.
  • b. The application is an inappropriate candidate to be clustered without creating a link to /opt/VRTSvcs.
  • c. The application could be clustered by creating a new directory under the root directory.
  • d. The application is an inappropriate candidate to be clustered without rewriting the source code.
  • e. The application could be clustered by creating a soft link from /usr/local/app to a shared file system.
