CompTIA Network+ Certification Exam Sample Questions (Q15-Q20):

NEW QUESTION # 15
An organization requires the ability to send encrypted email messages to a partner from an email server that is hosted on premises. The organization prefers to use the standard default ports when creating firewall rules. Which of the following ports should be open to satisfy the requirements?

  • A. 0
  • B. 1
  • C. 2
  • D. 3

Answer: C

Explanation:
Port 587 is the standard default port for sending email (SMTP) with TLS encryption, which is used to secure email transmissions between mail servers or between clients and mail servers. Allowing traffic over port 587 enables secure email sending while maintaining standard protocol usage.


NEW QUESTION # 16
Which of the following network cables involves bounding light off of protective cladding?

  • A. Twinaxial
  • B. Multimode
  • C. Single-mode
  • D. Coaxial

Answer: B

Explanation:
Multimode fiber optic cables involve the transmission of light signals that bounce off the core's cladding as they travel down the fiber. This characteristic differentiates it from single-mode fiber, where the light travels directly down the fiber without reflecting off the cladding.
Here are some detailed points about multimode fiber cables:
* Construction: Multimode fibers have a larger core diameter, typically 50 or 62.5 microns, compared to single-mode fibers, which have a core diameter of about 9 microns.
* Light Propagation: The larger core of multimode fiber allows multiple light modes to propagate.
These modes travel at different angles, leading to reflections off the core-cladding boundary.
* Distance and Bandwidth: Due to modal dispersion, where different light modes arrive at the receiver at different times, multimode fibers are suited for shorter distance applications compared to single- mode fibers. Typical distances are up to 550 meters for 10 Gbps Ethernet using OM4 multimode fiber.
* Applications: Multimode fibers are commonly used in LANs (Local Area Networks), data centers, and for shorter distance data transmission due to their cost-effectiveness and ease of installation.
Network References:
* CompTIA Network+ N10-007 Official Certification Guide, which covers fiber optic technologies, including the differences between multimode and single-mode fibers.
* Cisco Networking Academy: Provides training materials and reference guides on the properties of different fiber optic cables.
* Fiber Optic Association (FOA): A professional society dedicated to fiber optics, offering extensive information and certification on fiber optic technologies.
Multimode fibers are specifically designed for short-range communication with higher data rates and are typically used in environments like data centers, where high bandwidth over shorter distances is crucial. The reflections off the cladding, inherent to multimode fiber, facilitate this high-capacity communication.


NEW QUESTION # 17
A network technician was recently onboarded to a company. A manager has tasked the technician with documenting the network and has provided the technician With partial information from previous documentation.
Instructions:
Click on each switch to perform a network discovery by entering commands into the terminal. Fill in the missing information using drop-down menus provided.



Answer:

Explanation:
See the Explanation for detailed information on this simulation.
Explanation:
(Note: Ips will be change on each simulation task, so we have given example answer for the understanding) To perform a network discovery by entering commands into the terminal, you can use the following steps:
* Click on each switch to open its terminal window.
* Enter the command show ip interface brief to display the IP addresses and statuses of the switch interfaces.
* Enter the command show vlan brief to display the VLAN configurations and assignments of the switch interfaces.
* Enter the command show cdp neighbors to display the information about the neighboring devices that are connected to the switch.
* Fill in the missing information in the diagram using the drop-down menus provided.
Here is an example of how to fill in the missing information for Core Switch 1:
* The IP address of Core Switch 1 is 192.168.1.1.
* The VLAN configuration of Core Switch 1 is VLAN 1: 192.168.1.0/24, VLAN 2: 192.168.2.0/24, VLAN 3: 192.168.3.0/24.
* The neighboring devices of Core Switch 1 are Access Switch 1 and Access Switch 2.
* The interfaces that connect Core Switch 1 to Access Switch 1 are GigabitEthernet0/1 and GigabitEthernet0/2.
* The interfaces that connect Core Switch 1 to Access Switch 2 are GigabitEthernet0/3 and GigabitEthernet0/4.
You can use the same steps to fill in the missing information for Access Switch 1 and Access Switch 2.


NEW QUESTION # 18
An organization hasfour departmentsthat each need access todifferent resourcesthatdo not overlap. Which of the following should a technicianconfigurein order toimplement and assign an ACL?

  • A. VLAN
  • B. DHCP
  • C. VPN
  • D. STP

Answer: A

Explanation:
Comprehensive and Detailed Explanation:
VLANs (Virtual Local Area Networks)segment network trafficby department, allowingACLs (Access Control Lists)to be appliedbased on VLAN membership, improving security and resource isolation.
Breakdown of Options:
* A. VLAN-Correct answer.VLANs enablelogical network segmentation, allowingACLs per department.
* B. DHCP- Assigns IP addresses butdoes not control access.
* C. VPN- Providesremote access,not segmentation within a network.
* D. STP- Preventsswitching loops,not related to ACL implementation.


NEW QUESTION # 19
An organization requires the ability to send encrypted email messages to a partner from an email server that is hosted on premises. The organization prefers to use the standard default ports when creating firewall rules.
Which of the following ports should be open to satisfy the requirements?

  • A. 0

  • C. 2
  • D. 3

Answer: C

Explanation:
Port 587 is the standard default port for sending email (SMTP) with TLS encryption, which is used to secure email transmissions between mail servers or between clients and mail servers. Allowing traffic over port 587 enables secure email sending while maintaining standard protocol usage. (Reference:
