  A. Ensure a bottleneck is not coming from other devices on the network.
  B. Install the latest firmware for the device.
  C. Create a new VLAN for the access point.
  D. Make sure the SSID is not longer than 16 characters.
  E. Configure the AP in autonomous mode.
  F. Install a wireless LAN controller.
  A. Ensure a bottleneck is not coming from other devices on the network.
  B. Install the latest firmware for the device.

  ---

  Explanation/Reference:

  One possible cause of poor wireless performance is a bottleneck in the network, which means that other devices or applications are consuming too much bandwidth or resources and limiting the speed of the wireless access point. To troubleshoot this issue, the engineer should ensure that there is no congestion or interference from other devices on the network, such as wired clients, servers, routers, switches, or other wireless access points. The engineer can use tools such as network analyzers, bandwidth monitors, or ping tests to check the network traffic and latency12. Another possible cause of poor wireless performance is outdated firmware on the device, which may contain bugs or vulnerabilities that affect the functionality or security of the wireless access point. To troubleshoot this issue, the engineer should install the latest firmware for the device from the manufacturer's website or support portal. The engineer should follow the instructions carefully and backup the configuration before updating the firmware. The engineer can also check the release notes or changelog of the firmware to see if there are any improvements or fixes related to the wireless performance3 . The other options are not relevant to troubleshooting poor wireless performance. Creating a new VLAN for the access point may help with network segmentation or security, but it will not improve the speed of the wireless connection. Making sure the SSID is not longer than 16 characters may help with compatibility or readability, but it will not affect the wireless performance. Configuring the AP in autonomous mode may give more control or flexibility to the engineer, but it will not enhance the wireless speed. Installing a wireless LAN controller may help with managing multiple access points or deploying advanced features, but it will not increase the wireless performance.

• Question 984:

  Users have reported an issue connecting to a server over the network. A workstation was recently added to the network and configured with a shared USB printer. Which of the following is most likely causing the issue?

  A. The switch is oversubscribed and cannot handle the additional throughput.
  B. The printer is tying up the server with DHCP discover messages.
  C. The web server's back end was designed for only single-threaded applications.
  D. The workstation was configured with a static IP that is the same as the server.
  D. The workstation was configured with a static IP that is the same as the server.

  ---

  Explanation/Reference:

  If a workstation is configured with a static IP address that is the same as the server's IP address, it can lead to network conflicts and connectivity issues. This is known as an IP address conflict, where two devices on the same network have the same IP address.

• Question 985:

  Which of the following describes the differences between switches and hubs?

  A. Switches operate on the physical layer, while hubs operate on the data link layer.
  B. Switches operate on the session layer, while hubs operate on the transport layer.
  C. Switches operate on the data link layer, while hubs operate on the physical layer.
  D. Switches operate on the transport layer, while hubs operate on the data link layer.
  C. Switches operate on the data link layer, while hubs operate on the physical layer.

  ---

  Explanation/Reference:

  Switches operate at the data link layer (Layer 2) of the OSI model and make decisions based on MAC addresses. Hubs, on the other hand, operate at the physical layer (Layer 1) and simply repeat the signals they receive to all connected

  devices without any filtering or decision-making.

• Question 986:

  Users report that the network is slower than usual when accessing on-premises email. Which of the following should a network technician do to confirm the issue?

  A. Review the logging levels of network devices.
  B. Check the audit logs to see if users are accessing email
  C. Compare the network baselines to the current network status.
  D. Verify that users who are trying to access email have LDAP accounts
  C. Compare the network baselines to the current network status.

• Question 987:

  Following a fire in a data center, an executive is concerned about the amount of data that must be reentered. Which of the following describes the executive's concern?

  A. RTO
  B. MTBF
  C. MMTR
  D. RPO
  D. RPO

  ---

  Explanation/Reference:

  A recovery point objective (RPO) is the maximum length of time permitted that data can be restored from, which may or may not mean data loss. It is the age of the files or data in backup storage required to resume normal operations if a computer system or network failure occurs.

• Question 988:

  A technician needs to configure a Linux computer for network monitoring. The technician has the following information:

  Linux computer details:

  

  Switch mirror port details:

  

  After connecting the Linux computer to the mirror port on the switch, which of the following commands should the technician run on the Linux computer?

  A. ifconfig ecth0 promisc
  B. ifconfig eth1 up
  C. ifconfig eth0 10.1.2.3
  D. ifconfig eth1 hw ether A1:B2:C3:D4:E5:F6
  A. ifconfig ecth0 promisc

  ---

  Explanation/Reference:

  The 'ifconfig eth0 promisc' cmd would enable promiscuous mode on eth0 so the interface can capture and process network traffic coming to it. The switch's mirror port is duplicating traffic on another port on the switch and sending the mirrored traffic through its mirror port which is connected to the linux computer on eth1.

• Question 989:

  An organization has a factory automation solution that requires accurate timing between devices. Which of the following should the network administrator implement?

  A. PTP
  B. NTP
  C. NTS
  D. DoT
  A. PTP

  ---

  Explanation/Reference:

  PTP is a highly accurate time synchronization protocol used in industries and applications where precise time is critical, such as telecommunications, finance, and industrial automation. PTP is designed for precisely synchronizing the clocks of devices within a network. It provides highly accurate time distribution by synchronizing the clocks to a master clock, ensuring the devices maintain very close time alignment. This level of precision is crucial in scenarios where timing between devices needs to be synchronized, such as in factory automation solutions where events or processes are time-dependent and require exact timing for proper execution.

• Question 990:
