In Huawei public cloud, which of the following does not include the ELB scheduling algorithm?

Question

Options

• AARP algorithm
• BRound Robin Weighting Algorithm
• CWeighted Least Connections
• DSource IP address

• A
  74% (14)
• B
  5% (1)
• C
  5% (1)
• D
  16% (3)

Explanation

ARP (Address Resolution Protocol) is a network-layer protocol used to resolve IP addresses to MAC addresses - it has no role in distributing traffic across backend servers, so it is not and cannot be an ELB scheduling algorithm. Options B, C, and D are all legitimate Huawei ELB algorithms: Weighted Round Robin cycles through servers in proportion to their assigned weights, Weighted Least Connections sends new requests to whichever server has the fewest active connections relative to its weight, and Source IP hashing ensures requests from the same client IP consistently reach the same backend server. To avoid confusion on exams, remember that ELB algorithms are about deciding where to send traffic, while ARP is about finding a device's hardware address - these operate at completely different layers of the network stack and serve unrelated purposes.
