________ 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.

How do modern routers differ from traditional routers in terms of functionality and network management?

  • Application Layer Gateway (ALG)
  • Dynamic Routing Protocols
  • Network Address Translation (NAT)
  • Packet Filtering
Modern routers employ dynamic routing protocols, enhancing network management and adaptability compared to traditional routers.

The _______ field in the IPv4 header is used to limit the lifespan of a packet.

  • Checksum
  • Destination Address
  • Source Address
  • TTL (Time to Live)
The Time to Live (TTL) field in the IPv4 header is used to limit the lifespan of a packet by specifying the maximum number of hops the packet can take.

The ________ in SDN architecture is responsible for forwarding data packets based on the rules set by the controller.

  • Data Plane
  • Control Plane
  • Management Plane
  • Forwarding Plane
The Data Plane in SDN architecture is responsible for forwarding data packets based on the rules set by the controller.

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.
