Question List

Question1: In a two node HA cluster, two identical servers (same CPU, memory, and I/O card configurations) are designed to host the database tier of a 3-tier application. They are connected to a large external disk array through two fibre channel links. Under normal operations the production database is hosted on server A and a batch reporting tool is hosted on server B.
What are possible remedies for slow performance of the production database during non-failure operation? (Choose two).

Question2: Which file controls the default behavior of the boot process to activate all known volume groups at boot time?

Question3: In a two-node HA cluster, two servers are specified to host the application and database servers of a 3-tier application. Client systems connect through an external network.
Which techniques are employed to provide a degree of high availability to the clients that connect to the application tier? (Choose two).

Question4: During a rolling Serviceguard software upgrade, which statement is correct?

Question5: The function of the cmlvmd daemon in a standard Serviceguard cluster is to ensure the volume groups are activated how?

Question6: When a RUN_SCRIPT_TIMEOUT or HALT_SCRIPT_TIMEOUT value is set and
the control script hangs, causing the timeout to be exceeded, Serviceguard kills the script and marks the package "Halted." What else is also true? (Choose two).

Question7: Which statements are true about a Continental Cluster product? (Choose two).

Question8: Which statement is true regarding Continental Cluster?

Question9: Which statement is true regarding Metropolitan Cluster?

Question10: Based on the following situation, you have created a Serviceguard package that performs disk resource monitoring using EMS. When all paths to the package's shared disk are disabled, a package failover is triggered.
Situation:
- There are two nodes in the cluster:
- The shared volume group is vg01 with the following disks:
/dev/dsk/c0t6d0 with alternate path /dev/dsk/c1t2d0
/dev/dsk/c0t5d0 with alternate path /dev/dsk/c1t1d0
- The vg01 disk device names are identical on both systems.
- vg01 is already cluster-aware.
Which lines should be added to the package configuration file to allow the package to monitor the disk resource?

Question11: If the NODE_FAIL_FAST_ENABLED option is set to YES in the package config file, how will the node behave if the package fails?

Question18: Which statement is true regarding a Metropolitan Cluster product?

Question19: What is true regarding Quorum Server?

Question20: DRAG DROP
Using drag and drop, order the necessary steps on each system to complete the task below. There is more than one possible answer.
Configure the existing active volume group vg_apps with the minor number
0x020000 on the node system_a to be shared between the two nodes system_a and system_b in the same Serviceguard cluster.

Question21: DRAG DROP
Configure a Serviceguard package by dragging and dropping the appropriate options into the empty fields.
The package will be called 'missionspace' and will have an IP address of 15.20.30.10 on the 15.20.30.0 network. A failure of the 15.20.30.0 network will cause the package to fail over to the adoptive node. The package will run on FIONA as the primary node and fail back from SHREK manually. A service process called space_monitor will be used to monitor the health of the package. The monitor is started by running the script /etc/cmcluster/EPCOT/spacemon and passing it the argument "monitor".
A failure of this process 2 times will cause the package to fail to the alternate node without affecting the node it is running on.
The package mounts the logical volume /dev/vg04/moonvol at the directory
/opt/moon. The filesystem type should be the Veritas file system and mounted with a delaylog option.
The application is started by the command: /opt/moon/missionspace/takeoff.sh and stopped by the command: /opt/moon/missionspace/touchdown.sh.

Question22: Exhibit:

Which statement is true based on the package log file?

Question23: A collection of templates and scripts that integrate popular applications into a Serviceguard environment are referred to as what?
