   A system administrator is configuring a new NGINX load balancer for a pool of four backend servers. The servers have different hardware specifications: two are older and slower, and two are newer and faster. The administrator wants to ensure that the faster servers receive a larger share of the traffic. Which configuration should they use?

   • AUse the ip_hash algorithm.
   • BUse the default round robin algorithm.
   • CUse the round robin algorithm with the weight parameter on each server.
   • DUse the least_conn algorithm.

   A system administrator is configuring a new NGINX load balancer for a set of three backend web servers. The servers are named web1, web2, and web3, and they listen on port 8080. The administrator writes the following configuration snippet: ``` http { upstream backend { server web1:8080; server web2:8080; server web3:8080; } server { listen 80; location / { proxy_pass http://backend; } } } ``` What is the default load balancing algorithm used by this configuration?

   • ALeast connections
   • BIP hash
   • CRandom
   • DRound robin
