  B. Syslog

  C. NetFlow

  D. SNMPv3

  Correct Answer: D

  SNMPv3 (Simple Network Management Protocol version 3) provides device monitoring with authentication and encryption. This enhances network visibility and security by ensuring that monitoring data is securely transmitted and access to

  network devices is authenticated.

  Authentication: SNMPv3 includes robust mechanisms for authenticating users accessing network devices.

  Encryption: It provides encryption to protect the integrity and confidentiality of the data being transmitted.

  Network Management: SNMPv3 allows for detailed monitoring and management of network devices, ensuring better control and security.

• Question 213:

  Which of the following network cables involves bounding light off of protective cladding?

  A. Twinaxial

  B. Coaxial

  C. Single-mode

  D. Multimode

  Correct Answer: D

  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.

  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.

• Question 214:

  A network technician needs to install patch cords from the UTP patch panel to the access switch for a newly occupied set of offices. The patch panel is not labeled for easy jack identification. Which of the following tools provides the easiest way to identify the appropriate patch panel port?

  A. Toner

  B. Laptop

  C. Cable tester

  D. Visual fault locator

  Correct Answer: A

  A toner probe, often referred to as a toner and probe kit, is the easiest and most effective tool for identifying individual cables in a bundle, especially in situations where the patch panel is not labeled. The toner sends an audible tone through

  the cable, and the probe detects the tone at the other end, allowing the technician to quickly identify the correct cable.

  Functionality: The toner generates a tone that travels along the cable. When the probe is placed near the correct cable, it detects the tone and emits a sound. Ease of Use: Toner probes are straightforward to use, even in environments with

  many cables, making them ideal for identifying cables in unlabeled patch panels. Efficiency: This method is much faster and more reliable than manual tracing, especially in complex setups.

• Question 215:

  Which of the following best describes a group of devices that is used to lure unsuspecting attackers and to study the attackers' activities?

  A. Geofencing

  B. Honeynet

  C. Jumpbox

  D. Screened subnet

  Correct Answer: B

  A honeynet is a network of honeypots designed to attract and study attackers. Honeypots are decoy systems set up to lure cyber attackers and analyze their activities. A honeynet, being a collection of these systems, provides a broader view of attack methods and patterns, helping organizations improve their security measures.

• Question 218:

  Which of the following network topologies contains a direct connection between every node in the network?

  A. Mesh

  B. Hub-and-spoke

  C. Star

  D. Point-to-point

  Correct Answer: A

  In a mesh topology, every node is directly connected to every other node. This provides high redundancy and reliability, as there are multiple paths for data to travel between nodes. This topology is often used in networks where high

  availability is crucial.References:

• Question 219:

  A company receives a cease-and-desist order from its ISP regarding prohibited torrent activity. Which of the following should be implemented to comply with the cease-and-desist order?

  A. MAC security

  B. Content filtering

  C. Screened subnet

  D. Perimeter network

  Correct Answer: B

  Content filtering can be used to block or restrict access to websites and services that facilitate torrenting and other prohibited activities. By implementing content filtering, the company can comply with the ISP's cease-and-desist order and prevent users from accessing torrent sites and engaging in prohibited activities.References: CompTIA Network+ study materials.

• Question 220:

  A network engineer is now in charge of all SNMP management in the organization. The engineer must use a SNMP version that does not utilize plaintext data. Which of the following is the minimum version of SNMP that supports this requirement?

  A. v1

  B. v2c

  C. v2u

  D. v3

  Correct Answer: D

  SNMPv3 is the version of the Simple Network Management Protocol that introduces security enhancements, including message integrity, authentication, and encryption. Unlike previous versions (v1 and v2c), SNMPv3 supports encrypted communication, ensuring that data is not transmitted in plaintext. This provides confidentiality and protects against eavesdropping and unauthorized access.References: CompTIA Network+ study materials.
