H11-811 · Question #64
The CDR pool of a U1981 can store () CDRs.
The correct answer is D. 480000. Option D (480,000) is correct because the Huawei U1981's CDR pool is designed to buffer up to 480,000 call detail records locally before forwarding them to the billing server - this is the documented maximum capacity for this device's CDR storage. Options A (100,000), B…

Explanation
Option D (480,000) is correct because the Huawei U1981's CDR pool is designed to buffer up to 480,000 call detail records locally before forwarding them to the billing server - this is the documented maximum capacity for this device's CDR storage.
Options A (100,000), B (200,000), and C (240,000) are all plausible-sounding figures but represent fractions of the actual capacity. They may correspond to CDR limits on lower-tier or older Huawei gateway models, making them classic distractors designed to trip up candidates who conflate similar product specifications.
Memory tip: Think of the U1981 as a high-capacity device - 480,000 is the largest option and follows the pattern that enterprise-grade unified gateways are built to handle peak CDR accumulation during long billing server outages. When in doubt, the "big number for the big box" heuristic applies here: 480K = U1981.
