QUESTION 11
A customer has a 4-node cluster serving a few different applications. The storage requirements are not clearly defined and would be very unpredictable.
How would shared storage pools benefit this customer?
A. They reduce the total required storage by half.
B. They eliminate the need for multiple repository disks.

QUESTION 13
A customer needs a new server for their database currently running on a 16-core POWER7 4.1 GHz based server. Oracle has informed the customer that their SPARC T5 based servers are best suited for running databases, because the SPARC T5 has eight threads per core, while the current servers only allow for up to four threads per core.
Which of the following statements could be correctly used to repudiate the Oracle claim?
A. Databases are mostly single-threaded workloads. Scale-out POWERS servers have higher clock speeds and can scale to more cores than SPARC T5 servers.
B. Oracle T5 Servers are engineered to run Oracle workloads faster. Non-Oracle workloads will run slower on their hardware due to the amount of threads.
C. More threads will implicate more licensing for the database software. Less threaded processors provide a better TCO by reducing the licensing.
D. The number of threads cannot guarantee better performance. Servers based on POWERS have better per core performance in benchmarks when compared to SPARC T5 based servers.
Correct Answer: D
