Explanation:The Mean-Time to Switchover (MTSO) metric measures the time expected to complete a switchover from a severe failure to a replicated instance in a different geographical area.
Q34.
What do service performance metrics focus on?

a.

The maximum capacity of IT resources.

b.

The ability of an IT resource to recover from operational disturbances.

c.

The ability of an IT resource to perform its intended function under pre-defined conditions without experiencing failure.

d.

Measurable characteristics of network capacity.

Discuss
Answer: (c).The ability of an IT resource to perform its intended function under pre-defined conditions without experiencing failure. Explanation:Service performance metrics focus on the ability of an IT resource to perform its intended function under pre-defined conditions without experiencing failure.
Q35.
Why is it important for SLAs to include specific metric formulas?

a.

To make the SLA document shorter and easier to read.

b.

To provide detailed legal information about SLA compliance.

c.

To outline the tools and practices used by cloud providers for compliance checking.

d.

To clarify how SLA metrics are measured and calculated.

Discuss
Answer: (d).To clarify how SLA metrics are measured and calculated. Explanation:Including specific metric formulas in SLAs is important to clarify how SLA metrics are measured and calculated.
Q36.
What is the benefit of considering independent SLA monitoring for cloud consumers?

a.

It ensures that cloud providers meet their SLA guarantees.

b.

It reduces the cost of SLA management.

c.

It eliminates the need for SLA monitoring altogether.

d.

It allows cloud consumers to verify SLA compliance independently.

Discuss
Answer: (d).It allows cloud consumers to verify SLA compliance independently. Explanation:Considering independent SLA monitoring allows cloud consumers to verify SLA compliance independently, especially if there are suspicions that SLA guarantees are not always being met by the cloud provider.
Q37.
Why might cloud consumers want to keep a copy of historical SLA-related data even after ending their business relationship with a cloud provider?

a.

To track the cloud provider's compliance with the SLAs.

b.

To share the data with other cloud providers.

c.

To reduce the storage costs associated with historical data.

d.

To meet data privacy requirements or for future comparisons.

Discuss
Answer: (d).To meet data privacy requirements or for future comparisons. Explanation:Cloud consumers might want to keep a copy of historical SLA-related data even after ending their business relationship with a cloud provider for reasons such as meeting data privacy requirements or for future comparisons.
Q38.
