Answer:
A. 4 CPUs and 6 megabyte cache memory
B. 1.3157 x10^-9 nanoseconds
Explanation:
The Intel core i5 7500 is a seventh generation central processing unit with a 4 CPU core and a 6 megabyte cache memory. It executes task at a clock cycle of 5 clock cycle at a speed of 3.8 GHz.
The relationship between frequency and clock cycle is,
Clock cycle = 1 / ( frequent).
So, One clock cycle = 1 / 3.8 GHz
= 0.3 x10^-9
For five clock cycles = 5 x 0.3 x10^-9
= 1.3157 x10^-9 nanoseconds.
Answer:
B. Assign roles and privileges to users so that only job-relevant data is accessible to the user.
Explanation:
Certain departments will require certain information for certain processes. It is not recommendable for every user to access every information of the company as it may reveal vital information.
Hence, every role and department should be given certain privileges to information according to the tasks and needs of the role.

Answer:
The service model employed for the data storage capability of only CST is:
SaaS (Software as a Service).
Explanation:
The three cloud computing categories are Infrastructure as a Service (IaaS), Software as a Service (SaaS), and Platform as a Service (PaaS). The three cloud computing services provide different virtual computing resources. In the case of CST, it utilizes only the data storage software of a provider, who provides the data storage infrastructure, including cloud-based servers, while CST uses its own "laptop and desktop computers and other networking hardware and software to access the Internet efficiently."
