Page 178 - Cloud Essentials

__________.

A. content distribution networks
B. identity federation

C. virtualization

D. cloud relocation

A. Content distribution networks place cloud content closer
physically to users, which enhances the user experience because of
quicker access.
B, C, and D are incorrect. Identity federation uses a single identity

provider to authorize access to numerous computing services.
Virtualization makes cloud solutions possible, but it does not place
content closer to users. Cloud relocation is a fictitious term.

24. You are designing a solution to ensure your on-premises users will
always have access to public cloud services. What should you
consider?

A. Identity federation

B. Tablets instead of smartphones
C. Redundant network connections

D. Encryption

C. A single network connection to a cloud provider presents a
single point of failure.
A, B, and D are incorrect. Identity federation uses a single identity
provider to authorize access to numerous computing services; it does

not ensure access to cloud services. Whether users use tablets, laptops,
smartphones, or desktops does not affect whether cloud services are
reachable. Encryption protects sensitive data from unauthorized use but
is not related to accessing cloud services.

25. Cloud adoption does not remove the need for on-premises IT

personnel. Which task must local IT personnel undertake to ensure
cloud solutions are delivering business value?
A. Setting limits on OPEX costs

B. Monitoring application performance

C. Creating new virtual machines
D. Removing active virtual machines
