Fill in: 'We ___ the CDN cache the moment a page's underlying content changes.'
We 'purge the cache' — the standard, established CDN collocation for clearing stale edge content. The other options aren't the recognised term here.
2 / 5
Fill in: 'A full-site purge can ___ origin servers with a sudden spike of uncached requests.'
We say a purge will 'overwhelm' the origin — the standard collocation for causing a traffic surge it can't absorb. The other options aren't idiomatic here.
3 / 5
Fill in: 'We ___ purges by URL pattern instead of clearing the entire cache every time.'
We 'scope' a purge — the standard collocation for restricting it to specific paths. The other options are less idiomatic here.
4 / 5
Fill in: 'We ___ cache-control headers carefully so purges are rarely even necessary.'
We 'tune' headers — the standard collocation for calibrating cache behaviour. The other options are less idiomatic here.
5 / 5
Fill in: 'We ___ purge completion across all edge nodes before declaring the deploy finished.'
We 'confirm' completion — the standard collocation for verifying an operation finished everywhere. The other options are less idiomatic here.
