CompTIA Network+ Certification Exam Sample Questions (Q146-Q151):

NEW QUESTION # 146
Which of the following is the most secure way to provide site-to-site connectivity?

A. IKE
B. GRE
C. IPsec
D. VXLAN

Answer: C

Explanation:
IPsec (Internet Protocol Security) is the most secure way to provide site-to-site connectivity. It provides robust security services, such as data integrity, authentication, and encryption, ensuringthat data sent across the network is protected from interception and tampering. Unlike other options, IPsec operates at the network layer and can secure all traffic that crosses the IP network, making it the most comprehensive and secure choice for site-to-site VPNs.Reference: CompTIA Network+ study materials and NIST Special Publication 800-77.

NEW QUESTION # 147
A network engineer is completing a new VoIP installation, but the phones cannot find the TFTP server to download the configuration files. Which of the following DHCP features would help the phone reach the TFTP server?

A. Options
B. Lease time
C. Scope
D. Exclusions

Answer: A

Explanation:
DHCP Options: DHCP options allow additional configuration parameters, such as the address of a TFTP server, to be provided to clients during the DHCP lease process. This is essential for VoIP phones to locate the server for configuration files.

NEW QUESTION # 148
Which of the following best describes the transmission format that occurs at the transport layer over connectionless communication?

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

Answer: D

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. Reference: CompTIA Network+ Exam Objectives and official study guides.

NEW QUESTION # 149
Which of the following is the most secure way to provide site-to-site connectivity?

A. IKE
B. GRE
C. IPsec
D. VXLAN

Answer: C

Explanation:
IPsec (Internet Protocol Security) is the most secure way to provide site-to-site connectivity. It provides robust security services, such as data integrity, authentication, and encryption, ensuring that data sent across the network is protected from interception and tampering. Unlike other options, IPsec operates at the network layer and can secure all traffic that crosses the IP network, making it the most comprehensive and secure choice for site-to-site VPNs.

NEW QUESTION # 150
Which of the following is a characteristic of the application layer?

A. It relies upon other layers for packet delivery.
B. It checks independently for packet loss.
C. It performs address translation.
D. It encrypts data in transit.

Answer: A

Explanation:
Introduction to OSI Model:
The OSI model is a conceptual framework used to understand network interactions in seven layers:
Physical, Data Link, Network, Transport, Session, Presentation, and Application.
Application Layer:
The application layer (Layer 7) is the topmost layer in the OSI model. It provides network services directly to end-user applications. This layer facilitates communication between software applications and lower layers of the network protocol stack.
Reliance on Other Layers:
The application layer relies on the transport layer (Layer 4) for data transfer across the network.
The transport layer ensures reliable data delivery through protocols like TCP and UDP.
The network layer (Layer 3) is responsible for routing packets to their destination.
The data link layer (Layer 2) handles node-to-node data transfer and error detection.
The physical layer (Layer 1) deals with the physical connection between devices.
