Page 188 - Cloud Essentials

A. Clouds do not offer data encryption.

B. Data must be stored within national boundaries.
C. Data in virtual servers is unreliable.

D. Cloud data cannot be backed up.

B. Some cloud providers have data centers in many countries, and

data from one country might be replicated to another; this could present
legal and jurisdiction ambiguities.
A, C, and D are incorrect. Many cloud solutions offer encryption,
and for those that do not, you can encrypt your data before storing it in
the cloud. Virtual servers are very reliable, and so is their data. Cloud
data can be backed up.

49. What new IT service risk is a result of cloud adoption?

A. Loss of network connectivity

B. Loss of encryption keys
C. Loss of decryption keys

D. Failure of a hard disk

A. Losing network connectivity means losing access to cloud IT
services and data. Redundant network connections should be
configured.

B, C, and D are incorrect. Encryption and decryption key loss is not
a problem specific to cloud adoption. Cloud providers use redundant
disk arrays for data, so a hard disk failure will not interrupt IT service
operation.

50. How does cloud adoption affect IT budgets?

A. IT budgets increase.

B. IT budgets decrease.
C. IT budgets remain the same.

D. IT budgets must account for the “pay-as-you-go” model.

D. Instead of a yearly or quarterly IT budget cycle, cloud elasticity
means costs are much more variable.
A, B, and C are incorrect. IT budgets normally decrease to reflect
the lack of capital expenditures. This may take time to become

apparent because of asset depreciation methods of accounting, as well
