CompTIA N10-008 Online Questions & Answers

• Question 321:

  A technician is installing the Wi-Fi infrastructure for legacy industrial machinery at a warehouse. The equipment only supports 802.11a and 802.11b standards. Speed of transmission is the top business requirement. Which of the following is the correct maximum speed for this scenario?

  A. 11Mbps
  B. 54Mbps
  C. 128Mbps
  D. 144Mbps
  B. 54Mbps

  ---

  Explanation/Reference:

  802.11b (Wi-Fi 1) 11 Mbps 100 meter maximum effective range

  802.11a (Wi-Fi 2) 54 Mbps 50 meter maximum effective range

• Question 322:

  A network administrator is configuring a new switch and wants to ensure that only assigned devices can connect to the switch. Which of the following should the administrator do?

  A. Configure ACLs.
  B. Implement a captive portal.
  C. Enable port security.
  D. Disable unnecessary services.
  C. Enable port security.

  ---

  Explanation/Reference:

  Port security is a feature available on network switches that allows the administrator to control which devices are permitted to connect to individual switch ports. It enables the switch to limit and identify the MAC addresses allowed to access the network through specific switch ports.

  By configuring port security, the administrator can define and restrict the number of MAC addresses allowed on a port, specify which MAC addresses are permitted to access the port, and take actions (like shutting down the port) when unauthorized devices attempt to connect. This helps to prevent unauthorized devices from gaining network access via that switch port.

• Question 323:

  While setting up a new workstation, a technician discovers that the network connection is only 100 full duplex (FD), although it is connected to a gigabit switch.

  While reviewing the interface information in the switch CLI, the technician notes the port is operating at IOOFD but Shows many RX and TX errors. The technician moves the computer to another switchport and experiences the same issues.

  Which of the following is MOST likely the cause of the low data rate and port errors?

  A. Bad switch ports
  B. Duplex issues
  C. Cable length
  D. Incorrect pinout
  D. Incorrect pinout

• Question 324:

  A network technician is working to deploy a new subnet to support 500 hosts. The technician needs to limit the number of unused IP addresses. Which of the following subnets should the technician choose?

  A. 255.255.224.0
  B. 255.255.248.0
  C. 255.255.252.0
  D. 255.255.254.0
  D. 255.255.254.0

• Question 325:

  A user calls the IT department to report being unable to log in after locking the computer The user resets the password, but later in the day the user is again unable to log in after locking the computer.

  Which of the following attacks against the user IS MOST likely taking place?

  A. Brute-force
  B. On-path
  C. Deauthentication
  D. Phishing
  A. Brute-force

  ---

  Explanation/Reference:

  Active Directory - IT Department resets the password

  Brute-Force Attack - Every time user comes back to their computer, users acount is being locked. With that being said, I would assume someone is trying to guess their password to access the user computer while the user is away.

• Question 326:

  Which of the following would most likely be considered for an IDF installation in a secure facility?

  A. Full-size body scanners
  B. Iris scanner
  C. RFID badge readers
  D. Smart deadbolt
  C. RFID badge readers

  ---

  Explanation/Reference:

  An Intermediate Distribution Frame (IDF) in a secure facility typically houses networking equipment and connections. In this context, security measures are likely to involve access control to the networking infrastructure. RFID (Radio-Frequency Identification) badge readers are commonly used for secure access control in facilities. These readers can authenticate individuals based on RFID badges or cards, providing a secure means of access to network equipment.

  While options A (Full-size body scanners) and B (Iris scanner) are more associated with physical security measures for access to the facility, option D (Smart deadbolt) is related to securing physical doors and may not be directly tied to securing the network infrastructure in the IDF.

• Question 327:

  An IP address is maintained despite a failing UPS that causes a workstation to restart several times. Which of the following would allow this to occur?

  A. DHCP reservation
  B. DHCP scope
  C. Name server
  D. Root DNS server
  A. DHCP reservation

  ---

  Explanation/Reference:

  DHCP Reservation - basically you reserve an address for a specific device, that address now only gets assigned to that device, in the event the device isn't online, it will not be reassigned to anyone else.

• Question 328:

  To comply with industry requirements, a security assessment on the cloud server should identify which protocols and weaknesses are being exposed to attackers on the Internet. Which of the following tools is the MOST appropriate to complete the assessment?

  A. Use tcpdump and parse the output file in a protocol analyzer.
  B. Use an IP scanner and target the cloud WAN network addressing.
  C. Run netstat in each cloud server and retrieve the running processes.
  D. Use nmap and set the servers' public IPs as the targets.
  D. Use nmap and set the servers' public IPs as the targets.

  ---

  Explanation/Reference:

  Nmap (Network Mapper) is a popular and widely-used open source tool for network exploration, management, and security auditing. It can be used to identify which protocols and services are exposed to the Internet on a cloud server, by setting the server's public IP address as the target. Nmap can scan for open ports and associated services, and report on any vulnerabilities that are detected.

• Question 329:

  A company's users have been reporting excessive latency when connecting to the Internet. The network administration team submitted a change request to upgrade all the obsolete network equipment from 100Mbps to 1Gbps and It was approved. Which of the following documentation types will be needed to measure the success or failure of the upgrade project?

  A. Network performance baseline
  B. Network configuration documents
  C. Equipment Implementation Instructions
  D. Inventory management documentation
  A. Network performance baseline

• Question 330:

  Which of the following is a system that is installed directly on a server's hardware and abstracts the hardware from any guest machines?

  A. Storage array
  B. Type 1 hypervisor
  C. Virtual machine
  D. Guest QS
  B. Type 1 hypervisor

  ---

  Explanation/Reference:

  A type 1 hypervisor is a system that is installed directly on a server's hardware and abstracts the hardware from any guest machines. A hypervisor is a software layer that enables virtualization by creating and managing virtual machines (VMs)

  on a physical host. A type 1 hypervisor, also known as a bare-metal hypervisor or a native hypervisor, runs directly on the host's hardware without requiring an underlying operating system (OS). It provides better performance and security

  than a type 2 hypervisor, which runs on top of an existing OS and relies on it for hardware access. References:
