• Question 901:

  A network technician wants to ensure the backup configuration files for the network devices are not being altered after they are stored. Which of the following tasks should the network technician perform to achieve this goal?

  A. Compute the checksum of the backup file and document it separately.
  B. Store the backup files on a thumb drive and keep it in a desk drawer.
  C. Encrypt the drive the files are stored on using AES-256.
  D. Upload the backup files to a cloud storage service.
  A. Compute the checksum of the backup file and document it separately.

• Question 902:

  A technician performed a manual reconfiguration of a firewall, and network connectivity was reestablished. Some connection events that were previously sent to a syslog server are no longer being generated by the flrewal. Which of Vie following should the technician perform to fix the Issue?

  A. Adjust the proper logging level on the new firewall.
  B. Tune the filter for logging the severity level on the syslog server.
  C. Activate NetFlow traffic between the syslog server and the firewall
  D. Restart the SNMP service running on the syslog server.
  A. Adjust the proper logging level on the new firewall.

  Explanation/Reference:

  Logging level is a setting that determines what types of events are recorded by a device and sent to a syslog server. Different logging levels have different severity levels, ranging from emergency to debug. If the technician performed a manual reconfiguration of the firewall, it is possible that the logging level was changed or reset to a lower level that does not include the connection events that were previously sent to the syslog server. To fix the issue, the technician should adjust the proper logging level on the new firewall to match the desired level of detail and severity for the connection events.

• Question 903:

  A technician is troubleshooting a report about network connectivity issues on a workstation. Upon investigation, the technician notes the workstation is showing an APlPA address on the network interface. The technician verifies that the VLAN assignment is correct and that the network interlace has connectivity. Which of the following is MOST likely the issue the workstation is experiencing?

  A. DHCP exhaustion
  B. A rogue DHCP server
  C. A DNS server outage
  D. An incorrect subnet mask
  A. DHCP exhaustion

  ---

  Explanation/Reference:

  APIPA (Automatic Private IP Addressing) is a feature built into Windows operating systems that allows a computer to automatically assign itself an IP address when it is unable to obtain one through DHCP. When DHCP exhaustion occurs, new clients that attempt to join the network will not be able to obtain an IP address from the DHCP server, and as a result, the computer will use an APIPA address to communicate on the network.

• Question 904:

  A technician just validated a theory that resolved a network outage. The technician then verified that all users could access resources. Which of the following is the next step the technician should take in the network troubleshooting methodology?

  A. Verify the services are restored.
  B. Test a new theory.
  C. Write the lessons learned.
  D. Identify where the network outage is occurring.
  C. Write the lessons learned.

  ---

  Explanation/Reference:

  The network troubleshooting methodology is a systematic process of identifying and resolving network problems. It consists of eight steps:

  1.

  Identify the problem.

  2.

  Establish a theory of probable cause.

  3.

  Test the theory to determine the cause.

  4.

  Establish a plan of action to resolve the problem and identify potential effects.

  5.

  Implement the solution or escalate as necessary.

  6.

  Verify full system functionality and, if applicable, implement preventive measures.

  7.

  Document findings, actions, and outcomes.

  8.

  Write the lessons learned. The last step, writing the lessons learned, is important for improving the network troubleshooting skills and knowledge. It involves reviewing the entire troubleshooting process, analyzing the root cause of the problem, evaluating the effectiveness of the solution, and identifying any best practices, tips, or tools that can be used for future reference. Writing the lessons learned can also help to update the network documentation, policies, and procedures, and share the experience and feedback with other network professionals

• Question 905:

  A network administrator is installing a new IDS device that will collect logs and alert the administrator of breaches.

  The network infrastructure includes a modern, a firewall, and core and access switches.

  The modem is ISP provided and only forwards packets from the data circuit.

  The firewall handles stateful packet inspection, the ACL, and application layer filtering.

  Which of the following describes where the administrator should install the IDS device on the network to collect the MOST relevant information?

  A. In front of the modem and firewall
  B. Between the modem and firewall
  C. Behind the firewall on the core switch
  D. After the access switch
  A. In front of the modem and firewall

• Question 906:

  Which of the following must be functioning properly in order for a network administrator to create an accurate timeline during a troubleshooting process?

  A. NTP
  B. IP helper
  C. Syslog
  D. MySQL
  A. NTP

  ---

  Explanation/Reference:

  NTP is responsible for synchronizing the time across devices in a network, and Syslog relies on accurate time stamps to create an accurate timeline. If the NTP service is not functioning correctly, then the time on the devices in the network may be out of sync, and the timestamps in Syslog messages may not be accurate.

  it's important to ensure that the NTP service is functioning correctly when troubleshooting network issues that require an accurate timeline. By ensuring that the time on all devices in the network is in sync, network administrators can create an accurate timeline of events, making it easier to troubleshoot and identify the root cause of problems.

• Question 907:

  A technician is deploying a new switch model and would like to add it to the existing network monitoring software. The technician wants to know what metrics can be gathered from a given switch. Which of the following should the technician utilize for the switch?

  A. MIB
  B. Trap
  C. Syslog
  D. Audit log
  A. MIB

• Question 908:

  Which of the following attacks is typically used to guess a password?

  A. Brute-force
  B. DDoS
  C. DNS poisoning
  D. Rogue DHCP
  E. Ransomware
  A. Brute-force

• Question 909:

  Which of the following would a network administrator configure to set NTP settings for a specific subnet within DHCP?

  A. Reservation
  B. Lease time
  C. Scope options
  D. Exclusion range
  C. Scope options

• Question 910:

  A network administrator is designing a wireless network. The administrator must ensure a rented office space has a sufficient signal. Reducing exposure to the wireless network is important, but it is secondary to the primary objective. Which of the following would MOST likely facilitate the correct accessibility to the Wi-Fi network?

  A. Polarization
  B. Channel utilization
  C. Channel bonding
  D. Antenna type
  E. MU-MIMO
  D. Antenna type

  ---

  Explanation/Reference:

  The MOST likely factor to ensure the correct accessibility to the Wi-Fi network in the scenario described is the antenna type, as it affects the coverage, signal strength, and performance of a wireless network. The other options listed (polarization, channel utilization, channel bonding, MU-MIMO) may improve the performance of a wireless network, but are not the primary factor in ensuring the correct accessibility in this scenario.
