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.
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.
In a network using NAT, what happens to the IP address of a packet as it leaves the local network and enters the internet?
- It is encrypted
- It is translated to a private IP address
- It is translated to a public IP address
- It remains the same
In a network using NAT, the private IP address of a packet is translated to a public IP address as it leaves the local network and enters the internet.
A network administrator needs to ensure secure remote access to network devices for configuration and troubleshooting. What protocol or method would be most appropriate?
- Telnet
- SSH (Secure Shell)
- HTTP
- SNMPv1
Secure Shell (SSH) is the appropriate protocol for secure remote access to network devices for configuration and troubleshooting, providing encrypted communication.
How does MLPPP (Multilink Point-to-Point Protocol) differ fundamentally from standard PPP?
- It supports multiple logical links over a single physical connection.
- It uses a different encapsulation method.
- It is limited to synchronous communication.
- It only works over Ethernet connections.
MLPPP allows for the support of multiple logical links over a single physical connection, providing increased bandwidth and redundancy.
