For a data center requiring high levels of redundancy and interconnectedness between all systems, which topology would provide the optimal structure?
- Bus
- Mesh
- Ring
- Star
In a data center with high redundancy requirements, a mesh topology is optimal as it provides interconnectedness between all systems, minimizing points of failure.
Which basic tool is commonly used to verify connectivity between two network devices?
- Multimeter
- Protocol Analyzer
- Cable Tester
- Ping
The basic tool commonly used to verify connectivity between two network devices is the "Ping" tool, which sends a test message to check if a device is reachable.
How does NetFlow assist in network management?
- Captures and analyzes network traffic
- Configures routing protocols
- Monitors device temperature
- Manages user authentication
NetFlow assists in network management by capturing and analyzing network traffic to provide insights into network utilization and application performance.
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 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.
