Answer: /25
To determine the correct Pod per node CIDR range, we need to ensure the range can accommodate between 60 to 100 Pods per node. GKE reserves 4 IP addresses per node (for system services), so the CIDR size must provide at least 104 IPs (100 Pods + 4 reserved). - **Option A (/24):** Provides 256 IPs (256 - 4 = 252 usable). This exceeds the requirement but is unnecessarily large. - **Option B (/25):** Provides 128 IPs (128 - 4 = 124 usable). This meets both the minimum (60) and maximum (100) requirements efficiently. - **Option C (/26):** Provides 64 IPs (64 - 4 = 60 usable). This only meets the minimum requirement but fails the maximum. - **Option D (/28):** Provides 16 IPs (16 - 4 = 12 usable), which is insufficient. **/25 (Option B)** is the optimal choice as it satisfies the requirements without over-provisioning.
