Which type of network link is necessary to transport multiple VLANs across network devices?
- Access Link
- Ethernet Link
- Point-to-Point Link
- Trunk Link
A trunk link is necessary to transport multiple VLANs across network devices, allowing for the passage of tagged VLAN traffic.
In troubleshooting a network that frequently loses connection, what systematic approach should be used to pinpoint the exact cause?
- Check for interference in wireless networks
- Implement QoS for better connectivity
- Conduct a packet capture analysis
- Update network device firmware
To pinpoint the exact cause of frequent connection losses, a systematic approach involves conducting a packet capture analysis to examine network traffic and identify potential issues.
What is the primary benefit of switch stacking in a network environment?
- Better Performance
- Enhanced Redundancy
- Improved Security
- Increased Scalability
The primary benefit of switch stacking is increased scalability, allowing multiple switches to be interconnected and managed as a single logical unit.
The _______ mechanism in STP prevents the formation of loops by temporarily disabling redundant paths.
- Blocking
- Forwarding
- Listening
- Root Guard
The blocking mechanism in STP prevents the formation of loops by temporarily disabling redundant paths.
In WAN optimization, what is the main purpose of implementing compression techniques?
- Reduce data transfer time
- Increase data integrity
- Improve network security
- Minimize latency
The main purpose of implementing compression techniques in WAN optimization is to reduce data transfer time by compressing the data before transmission.
When designing a network monitoring system, an administrator decides to use a protocol that supports both polling and unsolicited updates from network devices. Which protocol should they use?
- SNMP
- Syslog
- NetFlow
- ICMP
SNMP (Simple Network Management Protocol) supports both polling (active requests for information) and unsolicited updates (traps) from network devices, making it suitable for a comprehensive network monitoring system.
A company's security policy requires that all remote communications with the corporate network must be encrypted and authenticated. Which technology would best fit these requirements?
- VPN (Virtual Private Network)
- SSL/TLS (Secure Sockets Layer/Transport Layer Security)
- IPsec (Internet Protocol Security)
- SSH (Secure Shell)
IPsec is commonly used for encrypting and authenticating remote communications, making it suitable for the described security policy.
In advanced network automation, what is the significance of using containerization technologies like Docker?
- Containers isolate network configurations for security
- Docker simplifies the deployment and scaling of network applications
- Containerization reduces the need for network automation
- Docker provides a graphical user interface for network management
Containerization technologies like Docker simplify the deployment and scaling of network applications in advanced network automation, enhancing flexibility and efficiency.
