NEW QUESTION # 450
Which of the following, in addition to a password, can be asked of a user for MFA?
Answer: C
Explanation:
MFA (Multi-Factor Authentication) requires factors from different categories:
Something you know # Password, PIN
Something you have # Smart card, hardware (hard) token
Something you are # Biometric
The correct second factor is a hard token.
A). PIN = something you know (same factor as password).
B). Favorite color = knowledge-based, same factor as password.
D). Mother's maiden name = weak knowledge-based, same factor as password.

NEW QUESTION # 451
Which of the following attacks can cause users who are attempting to access a company website to be directed to an entirely different website?
Answer: A
Explanation:
Network segmentation involves dividing a network into smaller segments or subnets. This is particularly important when integrating OT (Operational Technology) devices to ensure that these devices are isolated from other parts of the network. Segmentation helps protect the OT devices from potential threats and minimizes the impact of any security incidents. It also helps manage traffic and improves overall network performance.
NEW QUESTION # 452
A network administrator's device is experiencing severe Wi-Fi interference within the corporate headquarters causing the device to constantly drop off the network. Which of the following is most likely the cause of the issue?
Answer: B
Explanation:
Severe Wi-Fi interference within a corporate headquarters causing devices to constantly drop off the network is most likely due to too much wireless reflection. Wireless reflection occurs when Wi-Fi signals bounce off surfaces like walls, metal, or glass, causing multipath interference. This can lead to poor signal quality and frequent disconnections. Other causes like wireless absorption, too many repeaters, or too many client connections can also affect Wi-Fi performance, but excessive reflection is a common culprit in environments with many reflective surfaces.
Reference: CompTIA Network+ Certification Exam Objectives - Wireless Networks section.
NEW QUESTION # 453
A network administrator must implement a feature that supports redundancy and scaling on the switches at the distribution layer of the network. Which of the following is the best option?
Answer: B
Explanation:
The correct answer is B. Spanning tree . At the distribution layer, switch redundancy is common because multiple paths are usually built into the design to avoid a single point of failure. The problem with redundant Layer 2 paths is that they can create switching loops, broadcast storms, and unstable MAC address tables if nothing controls them. Spanning Tree Protocol solves that problem by logically blocking one or more redundant paths while still keeping those paths available as backups.
That makes spanning tree the best fit for a feature that supports both redundancy and safe scaling . As the switched environment grows, STP helps maintain a stable topology and prevents loop-related failures. If the active path fails, a blocked redundant path can be brought into service.
The other options do not address the real need. VLAN assignment is used to segment broadcast domains, but it does not manage redundant Layer 2 paths. Port speed only affects throughput on an interface. Full duplex improves communication efficiency on a link, but it also does not provide redundancy control or loop prevention.
When a Network+ question mentions redundancy on switches and asks for the best switching feature, spanning tree is the strongest answer.
NEW QUESTION # 454
A customer calls the help desk to report issues connection to the internet. The customer can reach a local database server. A technician goes to the site and examines the configuration:
Which of the following is causing the user's issue?
Answer: B
Explanation:
The customer can accesslocal resources(a database server), which meanslocal networking is working.
However, the inability to reach the internet suggests an issue with thedefault gateway. If thedefault gateway is unreachable, packets will not be routed outside the local network.
Breakdown of Options:
* A. Incorrect DNS-DNS issueswould cause problemsresolving domain names, but the user should still be able to access external resources via IP addresses.
* B. Unreachable gateway-#Correct answer.If thedefault gateway is incorrect or unreachable, the devicecannot route traffic to the internet.
* C. Failed root bridge-STP (Spanning Tree Protocol) failurescauseswitching issues, but the user can still access local devices, meaning STP is not the problem.
* D. Poor upstream routing- Wouldaffect the entire network, not just one user.
