________ is a QoS technique that prioritizes packets based on their sensitivity to delay.
- Traffic Shaping
- Packet Sniffing
- Traffic Policing
- Low Latency Queuing
Low Latency Queuing is a QoS technique that prioritizes packets based on their sensitivity to delay.
________ is a common method where the functionality of each network component is verified in order, starting from the physical layer.
- Troubleshooting
- Ping Test
- Trace Route
- Layered Testing
Layered testing is a common method where the functionality of each network component is verified in order, starting from the physical layer.
_________ mode in Port Security allows dynamically learned MAC addresses to be retained even if the switch is restarted.
- Dynamic
- Secure
- Static
- Sticky
Sticky mode in Port Security allows dynamically learned MAC addresses to be retained even if the switch is restarted.
________ was a popular choice for digital telecommunication networks before being overshadowed by newer technologies.
- ISDN (Integrated Services Digital Network)
- ATM (Asynchronous Transfer Mode)
- Frame Relay
- X.25
ISDN (Integrated Services Digital Network) was a popular choice for digital telecommunication networks before being overshadowed by newer technologies like broadband and fiber optics.
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.
