TOPIK Practice – TOPIK I 어휘 [vocabulary] 1–5 (5/23/2026) – centerpoint outage

정답: C. 정전

How to solve: The sentence describes a sudden event in the central server that caused service interruption. '정전' (power outage) is a type of 'outage' that fits the context of service disruption due to a server issue. '연결' (connection) and '복구' (restoration) are the opposite of an outage, and '해결' (solution) refers to resolving a problem, not the problem itself.

A — '연결' means connection. It does not fit the context of service interruption.

B — '복구' means restoration or recovery. This would happen after an outage, not be the outage itself.

C — '정전' means power outage. A power outage in a central server would cause service interruption, making it the correct fit for 'outage'.

D — '해결' means solution. This is about resolving an issue, not the issue itself that causes interruption.

정답: A. 고장

How to solve: The sentence states that website access is impossible, indicating a problem with the server. '고장' (malfunction/breakdown) is the most appropriate word to describe a server issue that prevents access. '작동' (operation), '성공' (success), and '완료' (completion) refer to normal or positive states.

A — '고장' means malfunction or breakdown. A server malfunction would indeed make website access impossible.

B — '작동' means operation or functioning. This is the opposite of what is implied by '접속이 불가능합니다' (access is impossible).

C — '성공' means success. This does not fit the context of an issue preventing access.

D — '완료' means completion. This is unrelated to the server's operational status causing access issues.

정답: D. 중단

How to solve: The sentence mentions that many users experienced inconvenience, which suggests a negative event related to the network service. '중단되다' (to be suspended/interrupted) perfectly describes a situation where a service stops, causing inconvenience. '개시' (commencement), '유지' (maintenance), and '시작' (start) are positive or neutral actions that would not cause inconvenience.

A — '개시' means commencement or start. This would not cause inconvenience.

B — '유지' means maintenance or continuation. This implies the service is ongoing, not interrupted.

C — '시작' means start. Similar to '개시', it indicates a beginning, not an interruption.

D — '중단' means suspension or interruption. A sudden interruption of network service would certainly cause inconvenience to users.

정답: A. 재개

How to solve: The sentence indicates that problems persist 'even after' a certain action, and they are investigating the cause. This implies that the service was restarted or resumed, but the issue wasn't resolved. '재개' (reopening/resumption) fits this context, suggesting the service was brought back online after an issue, but the underlying problem remains. '이용' (use), '발생' (occurrence), and '개선' (improvement) do not fit the sequence of events.

A — '재개' means resumption or reopening. If the service was resumed but problems continued, it indicates an ongoing issue requiring investigation.

B — '이용' means use. This does not fit with the idea of problems continuing after an action on the service itself.

C — '발생' means occurrence. While problems '발생' (occur), the phrase '서비스 ____ 후에도' suggests an action taken *on* the service.

D — '개선' means improvement. If the service improved, problems would likely not continue.

정답: C. 복구

How to solve: The sentence talks about completing an action related to 'all services due to a power outage' by this evening. The natural action after a power outage, especially when aiming for completion, is '복구' (restoration). '연결' (connection) is a part of restoration, '피해' (damage) is what happened due to the outage, and '점검' (inspection) is a process, not the ultimate completion goal in this context.

A — '연결' means connection. While service connection is part of restoration, '복구' is a more comprehensive term for bringing all services back to normal.

B — '피해' means damage or harm. This refers to the negative consequences, not the action of resolving them.

C — '복구' means restoration or recovery. Completing the restoration of services after a power outage is the most logical action to be completed by a specific time.

D — '점검' means inspection or check. While inspection might be done, the overall goal to be '완료될 예정입니다' (expected to be completed) is the full restoration.
