N10-009 Exam Dumps - CompTIA Network+ Questions and Answers

BGP (Border Gateway Protocol) is used for routing data between different ISPs, making it essential for the functioning of the internet. Its primary use is for exchanging routing information between autonomous systems, especially different ISPs. Preventing loops within a LAN ishandled by protocols like Spanning Tree Protocol (STP), while improving reconvergence times and sharing routes with a Layer 3 switch are functions of other protocols or internal mechanisms.

Malware refers to any malicious software that can exfiltrate confidential data, including spyware, trojans, and rootkits. This fits the scenario where unauthorized data transfer is occurring.

Breakdown of Options:

A. Adware – Displays ads, does not typically steal data.

B. Ransomware – Encrypts files but does not exfiltrate data.

C. Darkware – Not a real cybersecurity term.

D. Malware – Correct answer. Malicious software is responsible for unauthorized data exfiltration.

When high-bandwidth services like videoconferencing are introduced, two primary factors may degrade performance:

Incorrect QoS Settings (E):QoS (Quality of Service) is used to prioritize traffic. If not configured correctly, critical services like video may not get the necessary bandwidth and prioritization.

Network Congestion (F):Video services consume large amounts of data. If the network doesn’t have sufficient bandwidth or is not segmented properly, congestion will slow down all services.

DNS misconfiguration (A) would affect name resolution, not bandwidth.

Malware (C) could degrade performance, but is not tied to the described scenario.

Outdated software (D) may affect performance in some cases, but not directly linked to network congestion in this case.

Inadequate network security (B) isn't likely to cause general slowness related to video traffic.

✅ So, the most likely culprits are E. Incorrect QoS settings and F. Network congestion.
