1 / 5
Fill in: 'We ___ an eviction policy so Redis knows which keys to drop first once memory fills up.'
-
-
-
-
We 'configure a policy' — the standard collocation for setting up how a cache behaves under pressure. The other options aren't idiomatic here.
2 / 5
Fill in: 'A missing TTL on a hot key can ___ memory pressure that eventually evicts unrelated data.'
-
-
-
-
We say a missing TTL will 'cause' pressure — the standard collocation for the resulting problem. The other options aren't idiomatic here.
3 / 5
Fill in: 'We ___ an expiry on every cached value so stale entries don't linger indefinitely.'
-
-
-
-
We 'set an expiry' — the standard, simple collocation for configuring a TTL. The other options are less idiomatic here.
4 / 5
Fill in: 'We ___ eviction metrics closely so an undersized cache gets flagged before it hurts latency.'
-
-
-
-
We 'watch' metrics — the standard collocation for ongoing observation of a signal. The other options aren't idiomatic here.
5 / 5
Fill in: 'We ___ the maxmemory limit conservatively so Redis never gets killed by the OS for using too much RAM.'
-
-
-
-
We 'size' a limit — the standard collocation for choosing an appropriate capacity value. The other options are less idiomatic here.
