解説
問 47
- ア
正解 This question asks you to match each SLA item to the management area that its content targets. Item a “the amount of time the server is operating” represents the operating rate, that is, the availability of the service, so it belongs to Service availability management. Item b “the time from detecting that disk usage has reached the threshold until notification” is about monitoring the capacity and capability of the disk resource, so it belongs to Capacity management. Item c “the time from detecting unauthorized access until notification” is a response to a security event, so it belongs to Information security management. Therefore availability=a, capacity=b, information security=c, and the correct answer is ア.
Incorrectイ
Although availability=a is correct, assigning c to capacity and b to information security is wrong. Item b is about disk usage, a matter of resource capacity, so it belongs to Capacity management, and item c is about unauthorized access, a security matter, so it belongs to Information security management; b and c have been swapped.
Incorrectウ
Assigning b to availability and a to capacity is wrong. Item a is the server operating time and belongs to availability management, while item b is disk capacity and belongs to Capacity management; a and b have been swapped.
Incorrectエ
Assigning c to availability and a to information security is wrong. Item a is the server operating time and belongs to availability management, while item c is unauthorized access detection and belongs to Information security management; a and c have been swapped.
ここがポイント
- Distinguish the roles of the management areas in IT service management: Service availability management = operating rate and availability; Capacity management = processing power and the amount of resources such as disk; Information security management = response to security events such as unauthorized access.
- Read what each SLA metric is a number meant to guarantee, then link it to the corresponding management process.
