NEW QUESTION # 380
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?
Answer: D
Explanation:
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.
NEW QUESTION # 381
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.
Answer:
Explanation:
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.
NEW QUESTION # 382
Users are unable to access files on their department share located on file server 2.
The network administrator has been tasked with validating routing between networks hosting workstation A and file server 2.
INSTRUCTIONS
Click on each router to review output, identify any issues, and configure the appropriate solution.
If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.
Answer:
Explanation:
See the solution in Explanation.
Explanation:
To validate routing between networks hosting Workstation A and File Server 2, follow these steps:
Review Routing Tables:
Check the routing tables of Router A, Router B, and Router C to identify any missing routes.
Identify Missing Routes:
Ensure that each router has routes to the networks on which Workstation A and File Server 2 are located.
Add Static Routes:
If a route is missing, add a static route to the relevant destination network via the correct interface.
Routing Table:
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
S* 0.0.0.0/0 is directly connected, GigabitEthernet3
10.0.0.0/8 is variably subnetted, 4 subnets, 2 masks
C 10.0.4.0/22 is directly connected, GigabitEthernet2
C 10.0.6.0/24 is directly connected, GigabitEthernet2
L 10.0.6.1/32 is directly connected, GigabitEthernet2
172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks
C 172.16.27.0/30 is directly connected, GigabitEthernet3
L 172.16.27.1/32 is directly connected, GigabitEthernet3

These configurations ensure that each router knows the correct paths to reach Workstation A and File Server
2, resolving the connectivity issue.
NEW QUESTION # 383
Which of the following is a use case for a PaaS environment?
Answer: D
Explanation:
PaaS (Platform as a Service) is best suited for application development because it provides a managed platform that includes the runtime environment, development frameworks, middleware, databases (often), and build/deployment tooling. In a PaaS model, the cloud provider manages the underlying infrastructure (servers, storage, networking, OS patching, and often the application runtime), allowing developers to focus on writing code, testing, and releasing applications quickly. This aligns with Network+ cloud concepts where service models are compared by responsibility: PaaS reduces operational overhead for the customer and accelerates development through standardized environments and automation.
Mobile access is a use case for remote access solutions (VPN, zero trust access, MDM), not specifically PaaS.
An e-commerce site could be hosted using many models (IaaS, PaaS, SaaS), so it's not the most specific match. Cloud-native software describes an architectural style (microservices, containers, managed services) and can be built using PaaS components, but it is broader than a single "use case" and is not as directly tied to the PaaS definition as application development is. Therefore, application development is the clearest and most accurate PaaS use case.
NEW QUESTION # 384
A network technician implements a switch with multiple VLANs. Which of the following items should the technician configure to ensure that clients can communicate with clients in other VLANs?
Answer: D
Explanation:
A switched virtual interface provides a Layer 3 interface for each VLAN, enabling inter-VLAN routing so devices in different VLANs can communicate.
