Updated 5V0-41.20 Exam Questions - Way to Achieve Success in VMware SD-WAN Troubleshoot Exam

Hello everyone, welcome to today's video! We'll dive into the core topics and questions of the 5V0-41.20 exam, including how to optimize network performance, Quality of Service (QoS), application-aware routing, IPsec configuration, and checking WAN link status. We'll also use exam questions to deepen our understanding of these topics. Let's get started!

00:30 Quality of Service (QoS)
01:05 Application-aware Routing
01:38 IPsec Configuration Parameters
02:12 WAN Link Status

1. Quality of Service (QoS):

QoS is a way to manage network traffic so that important applications get priority over others. It helps reduce delays and jitter for critical apps, making sure they run smoothly even when the network is busy.

Let’s take a look at this exam question:
If users report high latency during peak hours, which two features should be configured to prioritize critical applications? (Choose two)
A. Rate limiting
B. Quality of Service (QoS)
C. Business Policy
D. Application-aware Routing
Answer: B, D

2. Application-aware Routing:

This feature lets network devices choose the best path for data based on the needs of specific applications and the current state of the network. It ensures that important apps get the fastest and most reliable routes, improving their performance.

Let’s take a look at this exam question:
What should be inspected first if a new SD-WAN Edge device fails to register with the Orchestrator?
A. The device's Internet connectivity
B. The configuration profile ID
C. The system time and date settings
D. The firmware version compatibility
Answer: A

3. IPsec Configuration Parameters:

IPsec sets up secure VPN tunnels, and getting its settings right is essential. This includes things like choosing the right encryption and making sure the keys match. Proper configuration keeps your data safe and the tunnel stable.

Let’s take a look at this exam question:
In troubleshooting VPN tunnel failures, what are two critical elements to verify? (Choose two)
A. IPsec configuration parameters
B. Overlay flow control settings
C. Physical interface status
D. Encryption and decryption keys
Answer: A, D

4. WAN Link Status:

The WAN link is basically your device's connection to the outside world. If it's down or not set up correctly, you won't be able to access external resources. It's important to check the physical connection, settings, and whether your internet service is working properly.

Let’s take a look at this exam question:
When an Edge device reports "No Connectivity" on its dashboard, what is the first configuration item to check?
A. Local LAN configuration
B. WAN link status
C. DNS settings
D. Firewall rules
Answer: B
