Following the implementation of a BYOO policy. some users in a high-density environment report slowness over the wireless connection. Some wireless controller reports indicate high latency and airtime contention. Which of the following is the most probable root cause?
Correct Answer: B
Band-steering is a feature that allows an AP to steer dual-band capable clients to the less congested 5GHz frequency, leaving the 2.4GHz frequency for legacy clients. Without band-steering, the AP may have more clients competing for the same channel on the 2.4GHz frequency, resulting in high latency and airtime contention. Reference: According to the CompTIA Network+ Certification Exam Objectives, one of the topics covered in the exam is "Given a scenario, use appropriate wireless technologies and configurations". One of the subtopics is "Band steering" 1. According to the PoliFi: Airtime Policy Enforcement for WiFi paper, "Band steering allows the access point to disable the 2.4 GHz band from probing the client device, so it responds only to the 5 GHz band, reducing the congestion on the 2.4 GHz band while taking advantage of the faster 5GHz band to improve user's network experience." 2. According to the Aruba Air Slice Tech Brief, "Air Slice minimizes airtime contention and efficiently groups Wi-Fi 6 and non-Wi-Fi 6 client devices to guarantee bit rate, and provide bounded latency and jitter simultaneously." 3.

A technician is installing multiple UPS units in a major retail store. The technician is required to keep track of all changes to new and old equipment. Which of the following will allow the technician to record these changes?
Correct Answer: A
Asset tags will allow the technician to record changes to new and old equipment when installing multiple UPS units in a major retail store. Asset tags are labels or stickers that are attached to physical assets such as computers, printers, servers, or UPS units. They usually contain information such as asset name, serial number, barcode, QR code, or RFID chip that can be scanned or read by an asset management system or software. Asset tags help track inventory, location, status, maintenance, and ownership of assets. Reference: https://www.camcode.com/asset-tags/asset-tagging-guide/
N10-008 Exam Question 118
A network administrator is investigating a performance issue on a dual-link connection-VPN and MPLS-to a partner network. The MPLS is the primary path, and the VPN is used as a backup. While communicating, the delay is measured at 18ms, which is higher than the 6ms expected when the MPLS link is operational but lower than the 30ms expected tor the VPN connection. Which of the following will MOST likely point to the root cause of the Issue?
Correct Answer: A
Asymmetric routing can occur when two routers have different paths for the same two hosts, resulting in increased latency and possible packet loss. According to the CompTIA Network+ Study Manual, "If the path from the source to the destination is not the same in both directions, the packets will take different routes and the latency can increase significantly." To confirm this, the network administrator should check the routing tables on both sides of the connection and ensure that the same path is used in both directions.
N10-008 Exam Question 119
A security engineer is installing a new IOS on the network. The engineer has asked a network administrator to ensure all traffic entering and leaving the router interface is available for the IDS. Which of the following should the network administrator do?
Correct Answer: A
a network tap is a way of connecting an IDS out of band, which means it does not interfere with the normal network traffic. A network tap allows you to view a copy of the network traffic transmitted over the media being tapped.
N10-008 Exam Question 120
Which of the following layers of the OSI model receives data from the application layer and converts it into syntax that is readable by other devices on the network?
Correct Answer: C
The OSI model is a conceptual framework that describes how data is transmitted and processed across a network. It consists of seven layers, each with a specific function and responsibility. The application layer (layer 7) is the highest layer of the OSI model and interacts with the user applications and services. It provides the interface and functionality for the end-user communication. The presentation layer (layer 6) is the layer below the application layer and receives data from it. It is responsible for converting the data into a common syntax and format that is readable by other devices on the network. It also handles encryption, compression, and translation of data. The network layer (layer 3) is the layer that handles the routing and addressing of data packets across different networks. It uses logical addresses, such as IP addresses, to identify the source and destination of the data. The physical layer (layer 1) is the lowest layer of the OSI model and deals with the transmission and reception of raw bits over the physical medium. It defines the electrical, mechanical, and procedural characteristics of the network devices and cables. Therefore, the correct answer is C. Layer 6, as it is the layer that receives data from the application layer and converts it into syntax that is readable by other devices on the network.
