A network administrator needs to configure a solution for securely transmitting sensitive data over the internet to a cloud service provider. Which setup should they consider?
- Direct Internet Connection
- Site-to-Site VPN
- Dedicated Leased Line
- Cloud Connect Service
A site-to-site VPN provides a secure connection over the internet, making it an appropriate choice for transmitting sensitive data to a cloud service provider.
When configuring a VPN, what is an essential consideration for ensuring secure data transmission?
- Using a static IP address for VPN endpoints to simplify configuration.
- Enabling split tunneling to optimize network performance.
- Implementing strong encryption algorithms and key management for data confidentiality.
- Disabling authentication methods to streamline the VPN connection process.
An essential consideration for ensuring secure data transmission in a VPN is implementing strong encryption algorithms and key management to maintain data confidentiality.
For advanced WAN troubleshooting, which is a key metric to monitor in a network performance management tool?
- Throughput
- Latency
- MTU (Maximum Transmission Unit)
- Round-Trip Time (RTT)
Latency is a key metric to monitor in a network performance management tool for advanced WAN troubleshooting, as it measures the delay in data transmission.
