Based on this information, which of the following unused resources should you remove to lower cost?
A. lb1
B. VNet2
C. pip1
D. nic0
E. VM3
Answer 35:
A and C
Notes 35:
The pricing for Standard Load Balancer is based on the number of rules configured (load balancer rules and NAT rules) and data processed. However, there is no hourly charge for the Standard Load Balancer itself when no rules are configured. Since this load balancer contains rules, it should be removed to save money.
In ARM deployment model, there is no charge for dynamic public IP addresses when the associated virtual machine is “stopped-deallocated”. However, you’re charged for a static public IP address irrespective of the associated resource (unless it is part of the first five static ones in the region). This resource should be removed.
