NEW QUESTION # 187
A company's network is experiencing high latency and packet loss during peak hours. Network monitoring tools show increased traffic on a switch. Which of the following should a network technician implement to reduce the network congestion and improve performance?

  • A. Spanning Tree Protocol
  • B. Load balancing
  • C. Quality of Service
  • D. Port mirroring

Answer: C

Explanation:
Quality of Service (QoS): This is a feature used in networking to prioritize certain types of traffic.
By configuring QoS, network administrators can allocate higher bandwidth to time-sensitive applications like VoIP, video conferencing, or critical business applications during peak usage times. This helps to reduce latency and packet loss, which are often caused by congestion.


NEW QUESTION # 188
A storage network requires reduced overhead and increased efficiency for the amout of data being sent. Which of the following should an engineer likely configure to meet these requirements>?

  • A. QoS
  • B. Link speed
  • C. Jumbo frames
  • D. 802.1q tagging

Answer: C

Explanation:
Jumbo frames are Ethernet frames with a payload greater than the standard maximum transmission unit (MTU) of 1500 bytes. Configuring jumbo frames can reduce overhead and increase efficiency in storage networks by allowing more data to be sent in each frame, thus reducing the number of frames needed to transmit the same amount of data.
Reduced Overhead: By sending larger frames, the relative overhead for headers and acknowledgments is reduced.
Increased Efficiency: Larger frames mean fewer packets to process, leading to better utilization of network bandwidth and improved performance in high-throughput environments like storage networks.
Configuration: Requires support from all devices in the network path, including switches and network interface cards (NICs).
Network Reference:
CompTIA Network+ N10-007 Official Certification Guide: Explains jumbo frames and their benefits in reducing network overhead.
Cisco Networking Academy: Provides training on network optimization techniques, including the use of jumbo frames.
Network+ Certification All-in-One Exam Guide: Covers advanced Ethernet features, including jumbo frames and their configuration for improved network performance.

* B. Enforce access control lists- ACLs help control access but donot disable unnecessary services.
* C. Perform content filtering- Content filtering controlsweb traffic,not port security.
* D. Set up a screened subnet- ADMZ (screened subnet)improves security but doesnot address open ports.
