QUESTION NO: 3
An administrator is evaluating consolidating Power servers running relational database management systems (RDBMS). After reviewing the collection of nmon andtopas data for the candidate systems, the administrator is concerned by the total amount of RAM that the consolidation seems to require, based on the RAM allocated to each candidate system.
The administrator reviews the memory sections of thetopas data to see if reducing total RAM required is possible. None of the systems indicate any activity to the paging spaces.
Which of the following metrics would help the administrator determine the minimum RAM required to host the RDBMS partitions in the consolidated environment?
A. Free pages
B. Persistent pages
C. Computational pages
D. Real pages-free pages
E. Computational pages + persistent pages
Answer: C Explanation:
QUESTION NO: 4
An administrator is asked to issue the following command on the system:
vmo-o lgpg_size=16777216-0 lgpg_regions=512
The administrator issues ‘svmon -G1 and notices that almost all of the memory in the system is used even though the primary application is not started.
What is the most likely reason this is occurring?
A. Large 16MB pages are always pinned in the memory.
B. Someone started another application which used the memory.
C. Use vmstat instead of ‘svmon -G’ to see memory consumption.
D. Active Memory Expansion is enabled and has a high expansion factor.

QUESTION NO: 8
A customer with a Power 780 has 2 LPARs supporting database servers, and 4 LPARs supporting web servers. The web servers are very busy during the daytime, and the database servers have heavy night time activity. More memory is needed to make applications process more quickly.
How can the customer minimize expenses while increasing memory for the web and database applications?
A. Use Active Memory Scheduling to allocate memory according to peak usage periods
B. Use Workload Manager to balance processor and memory usage across all partitions
C. Implement Active Memory Expansion to compress memory pages, using spare CPU cycles
D. Implement Active Memory Sharing to move unused memory from web servers to database at night
