What is a potential drawback of improper route summarization in a network?
- Enhanced network security
- Improved scalability
- Increased routing table size
- Reduced network latency
Improper route summarization can lead to an increased routing table size, negatively impacting network performance and scalability.
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.
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.
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.
