IBM Information Management DB2 10.5 pureScale Technical Mastery Test v3 Sample Questions:
1. Which of the following statements is FALSE when monitoring the high usage of lock memory in a DB2 pureScale environment?
A) Request for locks might be denied.
B) Lock escalations can take place if there is insufficient memory.
C) Performance will not be affected due to high usage of Lock Memory.
D) Data concurrency issues can arise due to a high number of lock escalations.
2. Consider the scenario where a database administrator is required to restore a database backup for a DB2 pureScale environment. Which of the following statements is correct?
A) The RESTORE DATABASE command will need to be executed on only one of the members within the cluster. This operation will restore both the database and metadata for all members.
B) The RESTORE DATABASE command will need to be executed on the shared storage to restore the database. The metadata cannot be retrieved until the shared storage is restarted.
C) The RESTORE DATABASE command will need to be executed on each DB2 member within the cluster to restore just the database. A separate command will be required to restore the metadata for each member.
D) The RESTORE DATABASE command will need to be executed on each DB2 caching facility within the cluster to restore just the database. All node metadata is not recoverable since it is not stored within database backups.
3. Which one of the following options is TRUE about High Availability and Disaster Recovery (HADR) feature?
A) HADR allows up to two HADR standby databases.
B) HADR allows up to four HADR standby databases.
C) HADR allows up to three HADR standby databases.
D) HADR allows up to five HADR standby databases.
4. Which of the following options is correct about possible configurations for DB2 pureScale's network topology?
A) DB2 pureScale supports multiple cluster interconnect adapter ports for the cluster caching facilities which increases the bandwidth to handle more requests, thus improving performance. It also supports multiple switches, which greatly improves network resiliency.
B) DB2 pureScale does not support multiple cluster interconnect adapter ports, but It supports multiple switches, which greatly improves network resiliency.
C) DB2 pureScale supports multiple cluster interconnect adapter ports for the cluster members which increases the bandwidth to process more transactions, thus improving performance. It also supports multiple switches, which greatly improves network resiliency.
D) DB2 pureScale supports multiple cluster interconnect adapter ports for both cluster caching facilities and members. It does not support multiple switches.
5. How does DB2 pureScale balance the workload among its members?
A) Workload balance must be handled by the application.
B) Workload balance cannot be handled by DB2 pureScale. It must be handled by a third-
party application.
C) Workload balance is handled by the Self Tuning Memory Manager (STMM) feature.
D) Workload balance is automatically performed by DB2 pureScale by rerouting the workload to members with lighter loads.
