質問 # 421
A network engineer needs to correlate findings and receive alerts if there are brute force attacks, DDoS attacks, or port scanning happening within their network. Which of the following network monitoring technologies should the engineer implement?
正解:A
解説:
A SIEM (Security Information and Event Management) platform is built to collect, correlate, and alert on security-relevant events across many sources, which is exactly what's needed to identify patterns such as brute force attempts, port scanning, and DDoS indicators. In Network+ (N10-009) security operations concepts, correlation is key: a SIEM can ingest logs from firewalls, IDS/IPS, servers, authentication systems, endpoint agents, and network devices, then apply rules/analytics to detect suspicious behavior that might not be obvious from a single log source. It can also generate real-time alerts, dashboards, and incident timelines-helping the engineer respond quickly and prioritize threats.
Packet capture provides deep visibility into traffic but is not inherently designed for enterprise-wide correlation and alerting without significant additional tooling and expertise. SNMPv3 is used for secure device monitoring (status, counters, performance) rather than detecting coordinated attack patterns. A syslog collector centralizes logs but generally does not provide the same level of correlation, enrichment, and automated alerting capabilities as a SIEM. Therefore, SIEM is the best answer.
質問 # 422
A network technician was recently onboarded to a company. A manager has tasked the technician with documenting the network and has provided the technician With partial information from previous documentation.
Instructions:
Click on each switch to perform a network discovery by entering commands into the terminal. Fill in the missing information using drop-down menus provided.

正解:
解説:
See the Explanation for detailed information on this simulation.
Explanation:
(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.
質問 # 423
Which of the following ports creates a secure connection to a directory service?
正解:C
解説:
LDAP (Lightweight Directory Access Protocol) uses port 389 for standard connections and port 636 for LDAP over SSL (LDAPS), which secures directory service communication.
Breakdown of Options:
A: 22 - SSH port, not used for directory services.
B: 389 - Used for LDAP, but not encrypted.
C: 445 - Used for SMB file sharing, not LDAP.
D: 636 - Correct answer. LDAPS (LDAP over SSL/TLS) secures directory authentication.
Reference:
CompTIA Network+ (N10-009) Official Study Guide - Domain 3.1: Compare and contrast network protocols.
RFC 4511: Lightweight Directory Access Protocol (LDAP)
質問 # 424
A newly opened retail shop uses a combination of new tablets, PCs, printers, and legacy card readers. Which of the following wireless encryption types is the most secure and compatible?
正解:B
解説:
WPA2/WPA3 mixed mode lets devices that support WPA3 use its stronger encryption while still allowing legacy devices that only support WPA2 to connect, balancing security with compatibility.
質問 # 425
A network administrator is responding to a request to configure a new IP phone. Which of the following should the network administrator do to allow data and voice traffic to be properly prioritized?
正解:B
解説:
To ensure voice and data traffic are properly prioritized for an IP phone, the administrator should modify (configure) QoS. In Network+ (N10-009), QoS is the primary mechanism used to prioritize latency-sensitive traffic such as VoIP. By classifying and marking voice frames/packets (often using DSCP/CoS values) and applying priority queuing, the network ensures voice traffic experiences minimal delay and jitter even when links are congested. This is essential for call quality because voice is highly sensitive to variation in delivery time and packet loss.
802.1Q tagging is important for VLAN separation (and many IP phone deployments use a voice VLAN), but VLAN tagging alone does not guarantee prioritization; it separates traffic, while QoS provides preferential treatment. Full duplex can reduce collisions on Ethernet links, but it does not implement traffic prioritization policies. Changing the native VLAN is a trunking/security configuration detail and not the correct action to prioritize voice versus data. In practice, networks often use both a voice VLAN (802.1Q) and QoS, but for the explicit requirement of prioritization, QoS is the correct answer.
