   Which of the following allows a switch to be divided into separate logical networks?

   • AVLAN
   • BSSL VPN
   • CNAT
   • DRADIUS

   Show answer

   Answer: A

   Explanation

   The correct option that allows a switch to be divided into separate logical networks is A. VLAN (Virtual Local Area Network). A VLAN is a method of creating logical, segmented networks within a physical network infrastructure. By assigning specific switch ports to different VLANs, you can effectively separate and isolate traffic, creating distinct broadcast domains. This enables you to have multiple virtual networks within a single physical switch, which can improve network security and management by controlling which devices can communicate with each other.

   A user on a SOHO network is unable to watch online videos, even at 240 pixels. The technician runs ipconfig from the user's computer and records the following: Connection-specific DNS Suffix .: lan Link-local IPV6 Address.........: fe80::1585:7fb2:b05f:7102%12 IPv4 Address....................: 192.168.1.131 Subnet Mask.....................: 255.255.255.0 Default Gateway.................: 192.168.1.1 The technician then connects a test laptop to the router via the user's Cat 5 cable and records the following information: Download: 85 mbps - Upload: 22 mbps - Ping: 28 ms - Which of the following is MOST likely causing the user's issue?

   • AIncorrect IP address
   • BFaulty NIC
   • CMisconfigured default gateway
   • DBad network cable

   Show answer

   Answer: B

   Explanation

   B. Faulty NIC Explanation: Based on the information recorded by the technician, the network connection appears to be functioning normally. The user's computer is properly configured with an IPv4 address, subnet mask, and default gateway, which should allow the user to access the internet and online videos. The high download and upload speeds and low ping time recorded from the test laptop also indicate that the network is working well. However, the user's inability to watch online videos suggests that there might be an issue with the network card (NIC) on the user's computer. The NIC might be faulty or malfunctioning, which is preventing the computer from receiving and processing the video data. The technician should try replacing the NIC to resolve the issue.

   A user submitted a help desk ticket to report that the Wi-Fi connection drops every time the microwave is used. A technician suspects the issue is related to interference. Which of the following should the technician do to provide the BEST long-term solution for the issue?

   • AChange the Wi-Fi operation channel.
   • BConfigure the Wi-Fi AP to 5GHz.
   • CIncrease the power output of the AP.
   • DChange the SSID to hidden.

   Show answer

   Answer: B

   Explanation

   Microwave Interference: Microwave ovens typically operate in the 2.4GHz frequency band. When a microwave is in use, it can emit electromagnetic interference in the 2.4GHz range, which can disrupt Wi-Fi signals in the same frequency band. This interference is a common cause of Wi-Fi dropouts. 5GHz Band: The 5GHz frequency band is less susceptible to interference from common household devices like microwaves and cordless phones that operate in the 2.4GHz band. By configuring the Wi-Fi AP to use the 5GHz band, you can reduce the likelihood of interference and improve Wi-Fi reliability.
