CompTIA Network+ Certification Exam Sample Questions (Q260-Q265):

NEW QUESTION # 260
Which of the following is a major difference between an IPS and IDS?

A. An IPS needs to be installed in line with traffic and an IDS does not.
B. An IPS is less susceptible to false positives than an IDS.
C. An IPS is signature-based and an IDS is not.
D. An IPS requires less administrative overhead than an IDS.

Answer: A

Explanation:
The key difference is that an Intrusion Prevention System (IPS) is installed in line with network traffic, allowing it to actively block threats. In contrast, an Intrusion Detection System (IDS) only monitors and alerts without actively blocking traffic.
Breakdown of Options:
A: An IPS needs to be installed in line with traffic and an IDS does not. # Correct answer. IPS actively prevents threats, while IDS only detects them.
B: An IPS is signature-based and an IDS is not. - False, both can use signature-based detection.
C: An IPS is less susceptible to false positives than an IDS. - False, both can produce false positives, depending on configurations.
D: An IPS requires less administrative overhead than an IDS. - False, IPS requires more administrative effort due to real-time blocking decisions.

NEW QUESTION # 261
After changes were made to a firewall, users are no longer able to access a web server. A network administrator wants to ensure that ports 80 and 443 on the web server are still accessible from the user IP space. Which of the following commands is best suited to perfom this testing?

A. nmap
B. Ping
C. Ifconfig
D. Dig

Answer: A

NEW QUESTION # 262
A network administrator is configuring a wireless network with an ESSID. Which of the following is a user benefit of ESSID compared to SSID?

A. Advanced security
B. Roaming between access points
C. Stronger wireless connection
D. Increased throughput

Answer: B

Explanation:
An Extended Service Set Identifier (ESSID) allows multiple access points to share the same SSID, enabling seamless roaming for users. This means that users can move between different access points within the same ESSID without losing connection or having to reauthenticate. This provides a better user experience, especially in large environments such as office buildings or campuses.References:CompTIA Network+ study materials.

NEW QUESTION # 263
A network engineer configures a new switch and connects it to an existing switch for expansion and redundancy. Users immediately lose connectivity to the network. The network engineer notes the following spanning tree information from both switches:
Switch 1
Port State Cost
1 Forward 2
2 Forward 2
Switch 2
Port State Cost
1 Forward 2
2 Forward 2
Which of the following best describes the issue?

A. The port cost should not be equal.
B. A root bridge needs to be identified.
C. The ports should use link aggregation.
D. The switch should be configured for RSTP.

Answer: B

Explanation:
The issue is that no root bridge has been identified. In STP, a root bridge is necessary to manage redundant paths and avoid loops in the network. Without a root bridge, all switches will assume they can forward traffic, causing a network loop and connectivity problems.

NEW QUESTION # 264
Which of the following is used to estimate the average life span of a device?

A. MTTR
B. MTBF
C. RPO
D. RTO

Answer: B

Explanation:
* Understanding MTBF:
* Mean Time Between Failures (MTBF):A reliability metric that estimates the average time between successive failures of a device or system.
* Calculation and Importance:
* Calculation:MTBF is calculated as the total operational time divided by the number of failures during that period.
* Usage:Used by manufacturers and engineers to predict the lifespan and reliability of a device, helping in maintenance planning and lifecycle management.
* Comparison with Other Metrics:
* RTO (Recovery Time Objective):The maximum acceptable time to restore a system after a failure.
* RPO (Recovery Point Objective):The maximum acceptable amount of data loss measured in time.
* MTTR (Mean Time to Repair):The average time required to repair a device or system and return it to operational status.
* Application:
* MTBF is crucial for planning maintenance schedules, spare parts inventory, and improving the overall reliability of systems.
