Question #19
What is the primary benefit of an Edge Cloud?
- A . Low latency
- B . Low Cost
- C . Large Bandwidth
- D . High Availability
Correct Answer: A
A
Explanation:
Low latency is the primary benefit of an Edge Cloud. Edge Cloud is a distributed cloud architecture that brings cloud resources closer to the end users and devices, reducing the distance and delay for data transmission1. Low latency is crucial for many 5G use cases that require real-time responsiveness, such as autonomous driving, remote surgery, smart manufacturing, etc2. Low cost, large bandwidth, and high availability are not the primary benefits of an Edge Cloud, although they may be achieved depending on the deployment scenario and the service level agreement.

Question #20
What are the main parameters of policy-based auto-scaling? (Select 2)
- A . Threshold
- B . Min/max values
- C . Priority
- D . Description
Correct Answer: A, B
A, B
Explanation:
The main parameters of policy-based auto-scaling are threshold and min/max values. Threshold is the value of a metric that triggers the scaling action, such as CPU utilization or memory usage1. Min/max values are the minimum and maximum number of instances or resources that can be scaled up or down1. Priority and description are not parameters of policy-based auto-scaling. Priority is the order of execution of policies in case of conflicting or overlapping conditions2. Description is the optional text that provides additional information about the policy2.
