CompTIA N10-008 Online Questions & Answers

• Question 221:

  A company is using a DHCP server with 12-hour leases for its device configurations. A user records the information that the DHCP server provides and uses the information to connect a device with a manual IP set. Over time, the user experiences intermittent connectivity and recurring connection timeouts. Which of the following is the MOST likely cause of the issue?

  A. A duplicate IP address is on the network.
  B. The user's device is pointing to an incorrect DNS server.
  C. The device is set to use an incorrect subnet.
  D. The device is set to use an incorrect gateway.
  A. A duplicate IP address is on the network.

• Question 222:

  A network technician has been asked to provide daily reports on network saturation. Which of the following would BEST reflect these statistics?

  A. Average bandwidth usage
  B. Error rate on trunk ports
  C. Packet drops to the ISP
  D. Processor utilization for the Internet router
  A. Average bandwidth usage

• Question 223:

  After a critical power issue, the network team was not receiving UPS status notifications. The network team would like to be alerted on these status changes. Which of the following would be BEST to use tor these notifications?

  A. Traps
  B. MB
  C. NetFlow
  D. Syslog
  A. Traps

  ---

  Explanation/Reference:

  Traps are a type of notification used in network management that allow a network device to send an alert to a network management system (NMS) when certain events occur, such as a change in status or a critical error. Traps are typically

  used to alert the network team to issues that require immediate attention, such as the power issue described in the scenario.

  MIB (Management Information Base) is a database of information used for managing and monitoring network devices. It is not typically used for sending notifications about status changes or other events.

  NetFlow is a protocol used for collecting and exporting information about the flow of network traffic. It is not typically used for sending notifications about status changes or other events.

  Syslog is a protocol used for sending system log messages over a network to a central logging server. It is not typically used for sending notifications about status changes or other events.

• Question 224:

  A software developer changed positions within a company and is now a sales engineer. The security team discovered that the former software developer had been modifying code to implement small features requested by customers. Which of the following would be the best thing for the security administrator to implement to prevent this from happening?

  A. A software patching policy
  B. A role-based access control policy
  C. Firewalls on the software development servers
  D. Longer and more complex password requirements
  B. A role-based access control policy

  ---

  Explanation/Reference:

  A role-based access control (RBAC) policy is a security measure that assigns permissions and privileges to users based on their roles and responsibilities within an organization. RBAC helps to enforce the principle of least privilege, which states that users should only have the minimum level of access required to perform their tasks. RBAC also helps to prevent unauthorized access, modification, or misuse of sensitive data or resources by limiting the scope and impact of user actions. A software patching policy, firewalls on the software development servers, and longer and more complex password requirements are all good security practices, but they do not directly address the issue of preventing the former software developer from modifying code. A software patching policy ensures that software is updated regularly to fix bugs and vulnerabilities, but it does not prevent a user from introducing new code changes. Firewalls on the software development servers protect the servers from external attacks, but they do not prevent a user from accessing the servers internally. Longer and more complex password requirements make it harder for attackers to guess or crack passwords, but they do not prevent a user from using their own valid credentials. References

• Question 225:

  An engineer is concerned about date and time synchronization across networked devices. Which of the following should be used to address this concern?

  A. NTP
  B. SIP
  C. IMAP
  D. SMB
  A. NTP

• Question 226:

  HOTSPOT

  You have been tasked with implementing an ACL on the router that will:

  1. Permit the most commonly used secure remote access technologies from the management network to all other local network segments.

  2. Ensure the user subnet cannot use the most commonly used remote access technologies in the Linux and Windows Server segments.

  3. Prohibit any traffic that has not been specifically allowed.

  INSRUCTIONS

  Use the drop-downs to complete the ACL.

• Question 228:

  While troubleshooting a network outage, a technician discovers symptoms that indicate a patch cable is connecting the core switch to the router. A network engineer confirms the theory is plausible, and the technician tests the cable. The cable passes the test, and the technician properly plugs the cable back into the correct network ports. However, the network outage continues. Which of the following is the NEXT step the technician should take to troubleshoot the network outage?

  A. Establish a new theory.
  B. Verify full system functionality.
  C. Establish a plan of action.
  D. Continue to work the original theory.
  A. Establish a new theory.
