What is an SLA? (Choose two)
- A . An SLA is used to provide automated, real-time testing and alarming for throughput, latency, and jitter across a provider’s network.
- B . An SLA is an agreement between a customer and a provider that dictates the treatment of customer traffic across the provider’s network.
- C . An SLA allows customers to control all traffic within the service provider’s network by prioritizing their traffic over others as desired.
- D . An SLA allows a customer to pre-mark traffic and ensure that traffic is treated as per the agreement within the provider’s network.
- E . An SLA is a standard set of network QoS policies that a provider shares to all its customers, allowing them to better understand the treatment of traffic within the provider’s network.
