Answer:

The correct answer is B)

Explanation:

The commit command allows us to:

• Consolidate, confirm

• committing refers to the idea of confirming a set of provisional changes permanently.

• A popular use is at the end of a database transaction.

•

The LOCK TABLE command should be used:

• when a lock of the mode specified in the table can be acquired.

• The command will wait for everything you need to get the lock,

• In case you cannot acquire the lock immediately, the NOWAIT option is specified so that the command cancels the transaction.

You are provisioning a server with eight-core 3 GHz CMP that can execute a workload with an overall CPI of 2.0 (assuming that L2
n200080 [17]

Answer:

The explanation for the question is given in the Explanation section below.

Explanation:

Throughout the query, we gave that we already have 8 core 3 GHz CMP and therefore it performs workflow in 2.0 CPI.

So,

(8 cores*3 GHz) /2.0 CPI = 12 billion/second guidance, we've turned GHz into seconds, so that's a billion years.

Well into the question considering whether he loses 6.67 L2 per 1 K direction.

So,

12*0.00667 = 80 million mistakes per second level-2. For an 8, so 32B*80 = 2560 MB per sec.

Whether the maximum storage capacity is double that of high as 2560*2 = 5120 MB per sec.

However, that's just throughout the DDR2-67 DIMM range. So, we should infer this, because only one storage source could be enough.
