質問 # 60
Which of the following BEST describes capacity planning?
A. Activities used to create a plan that manages resources to meet service demand
B. Determining the maximum amount that any resource can accommodate or deliver
C. Activities performed to manage provider resources and provide multiple services
D. Monitoring the percentage of capacity of resources being used over a time period
正解：A
解説：
Comprehensive and Detailed Explanation From Exact Extract:
SRE defines capacity planning as the discipline of ensuring that a system has enough resources to meet expected demand, both now and in the future. The SRE Book states: "Capacity planning ensures that services have sufficient resources available to meet reliability and performance targets, accounting for growth, trends, and forecasted usage." (SRE Book - Chapter: Capacity Planning). This involves forecasting workloads, analyzing trends, and creating plans to scale infrastructure so that service-level objectives can continue to be met.
Option C correctly describes capacity planning as creating a resource management plan to meet demand.
Option A refers to capacity monitoring, not planning.
Option B reflects generic resource management or cloud provider operations, not SRE capacity planning.
Option D refers to determining maximum capacity, which is a measurement activity-not full planning.
Thus, C is the correct SRE-aligned answer.

Which of the following BEST describes the relationship between service level objectives and service level indicators?
A. Service level objectives are the performance metrics for service level indicators
B. Service level indicators are the measurements for the service level objectives
C. Service level objectives are the measurements foe the service level indicators
D. Service level indicators are the performance targets for service level objectives
正解：B
質問 # 62
Known workarounds represent what type of toil?
A. No enduring value
B. Automatable
C. Tactical
D. Linear scaling
正解：A
解説：
Comprehensive and Detailed Explanation From Exact Extract:
Known workarounds represent toil that has no enduring value, one of the key characteristics of toil defined by the SRE framework.
From the Site Reliability Engineering Book, Chapter "Eliminating Toil":
"Toil is work that is manual, repetitive, automatable, tactical, has no enduring value, and scales linearly with service size." Known workarounds fit this definition because:
* They solve the same recurring problems repeatedly
* They do not permanently fix the underlying issue
* They consume engineer time without contributing long-term improvements These activities lack enduring value and should be eliminated through automation or engineering fixes.
Why the other options are incorrect:
* A. Linear scaling - Many forms of toil scale linearly, but this does not specifically describe workarounds.
* B. Tactical - Tactical means short-term, but not all tactical work is a workaround.
* C. Automatable - While some workarounds can be automated, not all are.
* D. No enduring value - This is the defining trait of workaround-type toil.
Therefore, option D is correct.

D. The likely results is failure where such targets are defined.
