CompTIA Updated N10-009 Exam Questions and Answers by catherine

Comprehensive and Detailed Explanation (paraphrased, aligned to N10-009):

An evil twin is a malicious wireless access point that impersonates a legitimate SSID. Once victims connect, the attacker can intercept and manipulate traffic, performing an on-path (man-in-the-middle) attack—capturing credentials, injecting content, or downgrading encryption.

B. DDoS overwhelms services with traffic; it’s not the typical follow-on from clients joining a rogue AP.

C. ARP spoofing is another way to become on-path on wired segments, but with an evil twin, the wireless association itself enables the on-path position.

D. Phishing is social engineering; while an evil twin could be used to present fake portals, the primary technical posture after connection is on-path.

(Note: Ips will be change on each simulation task, so we have given example answer for the understanding)

To perform a network discovery by entering commands into the terminal, you can use the following steps:

Click on each switch to open its terminal window.

Enter the command show ip interface brief to display the IP addresses and statuses of the switch interfaces.

Enter the command show vlan brief to display the VLAN configurations and assignments of the switch interfaces.

Enter the command show cdp neighbors to display the information about the neighboring devices that are connected to the switch.

Fill in the missing information in the diagram using the drop-down menus provided.

Here is an example of how to fill in the missing information for Core Switch 1:

The IP address of Core Switch 1 is 192.168.1.1.

The VLAN configuration of Core Switch 1 is VLAN 1: 192.168.1.0/24, VLAN 2: 192.168.2.0/24, VLAN 3: 192.168.3.0/24.

The neighboring devices of Core Switch 1 are Access Switch 1 and Access Switch 2.

The interfaces that connect Core Switch 1 to Access Switch 1 are GigabitEthernet0/1 and GigabitEthernet0/2.

The interfaces that connect Core Switch 1 to Access Switch 2 are GigabitEthernet0/3 and GigabitEthernet0/4.

You can use the same steps to fill in the missing information for Access Switch 1 and Access Switch 2.

Single-mode fiber is best suited for long-distance communication, often exceeding 10 km (6.2 miles). It ' s immune to EMI and offers high bandwidth — making it the ideal choice for connecting buildings across a city.

Coaxial (A) and Twinaxial (B) are used for shorter distances and specific use cases (e.g., storage or legacy systems).

Cat 5 (D) is limited to 100 meters and is not suitable for city-level interconnects.

✅ For long-distance, high-speed, and reliable communication between buildings, Single-mode fiber is the professional choice.

Recovery Point Objective (RPO) defines the maximum acceptable amount of data loss measured in time. If leadership states “no more than eight hours of data loss,” they are describing how far back the organization is willing to roll data after an outage or disaster—meaning backups, replication, snapshots, or journaling must ensure recoverable data is no older than eight hours. In Network+ terms, this is a core availability and resiliency planning concept: you choose an RPO based on business impact, then implement backup frequency/replication strategy to meet it. By contrast, Recovery Time Objective (RTO) is about how quickly services must be restored (downtime duration), not how much data can be lost. MTTR (Mean Time to Repair/Recover) is an operational reliability metric describing typical time to restore a system, and MTBF (Mean Time Between Failures) indicates expected time between failures—neither directly states acceptable data loss. Therefore, the metric matching “eight hours of data loss” is RPO.
