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.
What is a significant consideration when configuring ACLs on a network that includes both IPv4 and IPv6 traffic?
- A single ACL can effectively filter both IPv4 and IPv6 traffic
- ACLs are not applicable to IPv6 traffic
- ACLs for IPv4 and IPv6 must be configured separately
- IPv6 traffic is not subject to ACLs
When configuring ACLs for a network with both IPv4 and IPv6 traffic, it's crucial to consider that ACLs for each protocol must be configured separately to ensure proper filtering.
What is the benefit of using a 'top-down' approach in network troubleshooting?
- Speeds up the troubleshooting process by focusing on specific layers
- Prioritizes issues starting from the physical layer up to the application layer
- Resolves issues only at the application layer
- Skips the network layers for faster resolution
A top-down approach in network troubleshooting prioritizes issues starting from the physical layer up to the application layer, ensuring a systematic and efficient resolution process.
What kind of cable is best suited for network environments where electromagnetic interference is a concern?
- Coaxial Cable
- Fiber Optic Cable
- HDMI Cable
- Twisted Pair
Fiber optic cables are best suited for network environments where electromagnetic interference is a concern because they are immune to such interference.
IPv6's _________ feature allows devices to automatically configure themselves with a globally unique IP address without the need for a server.
- Stateless Address Autoconfiguration (SLAAC)
- Dynamic Host Configuration Protocol version 6 (DHCPv6)
- Neighbor Discovery Protocol (NDP)
- IPv6 over IPv4 tunneling
IPv6's Stateless Address Autoconfiguration (SLAAC) feature allows devices to automatically configure themselves with a globally unique IP address without the need for a server.
In SDN, _________ ensures the network's ability to dynamically adjust to changing business needs.
- Network virtualization
- Quality of Service (QoS)
- Traffic Engineering
- SDN Controller
In SDN, Traffic Engineering ensures the network's ability to dynamically adjust to changing business needs.
In IPv6, what is the primary role of the Neighbor Discovery Protocol (NDP)?
- Address Resolution Protocol (ARP) replacement
- Dynamic Host Configuration Protocol (DHCP) functionality
- Internet Control Message Protocol version 6 (ICMPv6) replacement
- Routing Information Protocol (RIP) for IPv6
The Neighbor Discovery Protocol (NDP) in IPv6 serves as a replacement for the Address Resolution Protocol (ARP) in IPv4, facilitating address resolution in the network.
What type of topology combines characteristics of linear bus and star topologies, and is commonly used in wireless networks?
- Bus
- Mesh
- Ring
- Star
A bus topology combines characteristics of linear bus and star topologies and is commonly used in wireless networks.
