A company has deployed a global HTTP Load Balancer with Cloud CDN to serve content to users worldwide. They notice high egress costs from the origin region. What is the most cost-effective solution to reduce egress from the origin?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Enable Cloud CDN with general-purpose cache mode

Using Cloud CDN with a general-purpose cache mode caches content at Google's edge locations, reducing requests to the origin and lowering egress costs for served content.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    Enable Cloud CDN with general-purpose cache mode

    Why this is correct

    Caching at edge reduces origin requests and egress.

  • ✗

    Use Private Google Access

    Why it's wrong here

    Private Google Access is for accessing Google APIs without internet, not for CDN.

  • ✗

    Increase the number of backend instances

    Why it's wrong here

    More instances increase capacity but do not reduce egress costs.

  • ✗

    Switch to a regional load balancer

    Why it's wrong here

    Regional LB would not reduce egress from origin; it may increase latency.
