A company plans to purchase a U1900 unified gateway. To support 1000 conference participants at most, A company should choose().

Question

Options

• AU1911
• BU1960
• CU1981
• DU1980

• A
  19% (6)
• B
  6% (2)
• C
  72% (23)
• D
  3% (1)

Explanation

Option C (U1981) is correct because the Huawei U1981 is the high-capacity model in the U1900 series, designed to support up to 1000 concurrent conference participants - exactly matching the company's maximum requirement. The U1911 (A) is an entry-level gateway with significantly lower conference capacity, making it insufficient for 1000 users. The U1960 (B) is a mid-range model that supports more users than the U1911 but still falls short of the 1000-participant threshold. The U1980 (D) is close in capability to the U1981 but lacks the full conference scalability needed - the "1" suffix in U1981 denotes the enhanced conference processing capacity over the base U1980.

Memory tip: Think of the model numbers as a capacity ladder - U1911 < U1960 < U1980 < U1981. When you see "1000 conference participants," the U1981 is the only model that clears that bar; the "81" variant is the one built for large-scale conferencing.
