CompTIA Network+ Certification Exam Sample Questions (Q218-Q223):

NEW QUESTION # 218
A network engineer is designing a secure communication link between two sites. The entire data stream needs to remain confidential. Which of the following will achieve this goal?

  • A. AH
  • B. ESP
  • C. GRE
  • D. IKE

Answer: B

Explanation:
* Definition of ESP (Encapsulating Security Payload):
* ESP is a part of the IPsec protocol suite designed to provide confidentiality, integrity, and authenticity of data by encrypting the payload and optional ESP trailer.
* Ensuring Confidentiality:
* Encryption: ESP encrypts the payload, ensuring that the data remains confidential during transmission. Only authorized parties with the correct decryption keys can access the data.
* Modes of Operation: ESP can operate in transport mode (encrypts only the payload) or tunnel mode (encrypts the entire IP packet), both providing strong encryption to secure data between sites.
* Comparison with Other Protocols:
* GRE (Generic Routing Encapsulation): A tunneling protocol that does not provide encryption or security features.
* IKE (Internet Key Exchange): A protocol used to set up a secure, authenticated communications channel, but it does not encrypt the data itself.
* AH (Authentication Header): Provides integrity and authentication for IP packets but does not encrypt the payload.
* Implementation:
* Use ESP as part of an IPsec VPN configuration to encrypt and secure communication between two sites. This involves setting up IPsec policies and ensuring both endpoints are configured to use ESP for data encryption.


NEW QUESTION # 219
A university is implementing anew campus wireless network. A network administrator needs to configure the network to supporta large number of devices and high-bandwidth demands from students.
Which of the followingwireless technologiesshould the administrator consider for this scenario?

  • A. 5G
  • B. Wi-Fi 6E
  • C. Bluetooth
  • D. LTE

Answer: B

Explanation:
Comprehensive and Detailed Explanation:
Wi-Fi 6Eis thebest choiceforhigh-density environments, as it provideshigher speeds, more capacity, and lower latency.


NEW QUESTION # 220
A network administrator wants users to be able to authenticate to the corporate network using a port-based authentication framework when accessing both wired and wireless devices. Which of the following is the best security feature to accomplish this task?

  • A. Access control list
  • B. 802.1X
  • C. Port security
  • D. MAC filtering

Answer: B

Explanation:
802.1X is a port-based network access control (PNAC) protocol that provides an authentication mechanism to devices wishing to connect to a LAN or WLAN. It is widely used for secure network access, ensuring that only authenticated devices can access the network, whether they are connecting via wired or wireless means.
802.1X works in conjunction with an authentication server, such as RADIUS, to validate the credentials of devices trying to connect.References:CompTIA Network+ study materials.


NEW QUESTION # 221
Which of the following best describes the transmission format that occurs at the transport layer over connectionless communication?

  • A. Segment
  • B. Datagram
  • C. Frames
  • D. Packets

Answer: B

Explanation:
At the transport layer, connectionless communication is typically handled using the User Datagram Protocol (UDP), which transmits data in units called datagrams. Unlike TCP, UDP does not establish a connection before sending data and does not guarantee delivery, making datagrams the correct term for the transmission format in this context. References: CompTIA Network+ Exam Objectives and official study guides.


NEW QUESTION # 222
Which of the following fiber connector types is the most likely to be used on a network interface card?

  • A. MPO
  • B. ST
  • C. SC
  • D. LC

Answer: D

Explanation:
* Definition of Fiber Connector Types:
* LC (Lucent Connector): A small form-factor fiber optic connector with a push-pull latching mechanism, commonly used for high-density applications.
* SC (Subscriber Connector or Standard Connector): A larger form-factor connector with a push-pull latching mechanism, often used in datacom and telecom applications.
* ST (Straight Tip): A bayonet-style connector, typically used in multimode fiber optic networks.
* MPO (Multi-fiber Push On): A connector designed to support multiple fibers (typically 12 or
24 fibers), used in high-density cabling environments.
* Common Usage:
* LC Connectors: Due to their small size, LC connectors are widely used in network interface cards (NICs) and high-density environments such as data centers. They allow for more connections in a smaller space compared to SC and ST connectors.
* SC and ST Connectors: These are larger and more commonly used in patch panels and older fiber installations but are less suitable for high-density applications.
* MPO Connectors: Primarily used for trunk cables in data centers and high-density applications but not typically on individual network interface cards.
* Selection Criteria:
* The small form-factor and high-density capabilities of LC connectors make them the preferred choice for network interface cards, where space and connection density are critical considerations.
