1. Question 481 · 871 in bank

   A technician would like to implement a low-latency Wi-Fi network. Which of the following standards should the technician deploy for the network if the expected user bandwidth is 450Mbps?

   • A802.11a
   • B802.11b
   • C802.11g
   • D802.11n

   Show answer

   Answer: D

   Explanation

   802.11n offers higher data rates and better performance compared to 802.11a, 802.11b, and 802.11g. It supports multiple input, multiple output (MIMO) technology, which allows for increased data throughput and improved efficiency, making it a good choice for higher bandwidth requirements.

   Which of the following attacks, if successful, would provide a malicious user who is connected to an isolated guest network access to the corporate network?

   • AVLAN hopping
   • BOn-path attack
   • CIP spoofing
   • DEvil twin

   Show answer

   Answer: A

   Explanation

   A. VLAN hopping VLAN hopping is an attack where an attacker exploits a misconfigured switch to gain unauthorized access to VLANs other than the one they should be in. In this case, if an attacker is on an isolated guest network and successfully performs VLAN hopping, they could potentially gain access to the corporate network, which is a security breach.

   A desktop support department has observed slow wireless speeds for a new line of laptops using the organization's standard image. No other devices have experienced the same issue. Which of the following should the network administrator recommend troubleshooting FIRST to resolve this issue?

   • AIncreasing wireless signal power
   • BInstalling a new WAP
   • CChanging the protocol associated to the SSID
   • DUpdating the device wireless drivers

   Show answer

   Answer: D

   Explanation

   D. Updating the device wireless drivers The first troubleshooting step the network administrator should recommend in this scenario is updating the device wireless drivers. Slow wireless speeds on new laptops, while other devices are not experiencing the same issue, could be due to outdated or incompatible wireless drivers on the laptops. Updating the drivers can often improve compatibility and performance.

   The following configuration is applied to a DHCP server connected to a VPN concentrator:

   

   There are 300 non-concurrent sales representatives who log in for one hour a day to upload reports, and 252 of these representatives are able to connect to the VPN without any Issues. The remaining sales representatives cannot connect to the VPN over the course of the day. Which of the following can be done to resolve the issue without utilizing additional resources?

   • ADecrease the lease duration
   • BReboot the DHCP server
   • CInstall a new VPN concentrator
   • DConfigure a new router

   Show answer

   Answer: A

   Explanation

   If you originally thought it was the subnet mask. The quest says "non-concurrent sales reps. So some of their computers are holding on to leases. Answer A will help bring back some the the IP's for reallocation.

   A technician needs to change an incoming fiber line into an RJ45 copper connection for uplinking a new switch. Which of the following would BEST satisfy this requirement?

   • AMedia converter
   • BF-type connector
   • CSmall form-factor pluggable
   • DPunchdown block

   Show answer

   Answer: A

   Explanation

   @3Ycam don't assume facts that are not presented in the question. You need to connect 2 different types of connections...hence a media converter is the answer.

   A new engineer at a company is working to understand the network. Which of the following diagrams should the engineer review to understand the paths traffic takes?

   • APhysical
   • BLogical
   • CWiring
   • DRack

   Show answer

   Answer: B

   Explanation

   To understand the paths that network traffic takes, the new engineer should review the Logical network diagram. The logical diagram provides an overview of how devices are interconnected and how data flows within the network, showing the logical relationships between devices, subnets, and network segments.

8. Question 488 · 871 in bank

   A network technician is attempting to increase throughput by configuring link port aggregation between a Gigabit Ethernet distribution switch and a Fast Ethernet access switch. Which of the following is the BEST choice concerning speed and duplex for all interfaces that are participating in the link aggregation?

   • AHalf duplex and 1GB speed
   • BFull duplex and 1GB speed
   • CHalf duplex and 100MB speed
   • DFull duplex and 100MB speed

   Show answer

   Answer: D

   Explanation

   The access switches are fast ethernet so only 100mb/full duplex. All interfaces would need to be set to the highest possible link speed of all devices, which is 100mb. The gigabit interfaces would need to be set to 100/full.

   A junior network engineer is trying to change the native network ID to a non-default value that can then be applied consistently throughout the network environment. Which of the following issues is the engineer attempting to prevent?

   • ADDoS
   • BARP spoofing
   • CVLAN hopping
   • DRogue DHCP

   Show answer

   Answer: C

   Explanation

   The junior network engineer is attempting to prevent VLAN hopping by changing the native network ID to a non-default value that can be consistently applied throughout the network environment. Explanation: VLAN hopping is a security vulnerability that can occur in situations where a switch incorrectly forwards traffic between different VLANs that should be isolated from each other. One common method attackers use to exploit VLAN hopping is by sending frames with 802.1Q tags (VLAN tags) that belong to different VLANs, causing the switch to incorrectly forward the traffic between VLANs.

    Which of the following BEST prevents unauthorized access to spare workstation inventory?

    • AAsset tags
    • BTamper detection
    • CSecurity camera
    • DLocking cabinet
    • ESmart lockers

    Show answer

    Answer: D

    Explanation

    D. Locking cabinet A locking cabinet physically secures spare workstation inventory, preventing unauthorized access to the equipment. It offers a tangible barrier that restricts entry unless authorized personnel have the necessary keys or access codes. While the other options can contribute to security measures, they might not provide the same level of physical protection against unauthorized access:
