An Intrusion Detection System (IDS) monitors and analyzes traffic to detect suspicious activity but does not sit in the traffic path, meaning it doesn't affect latency. In contrast, an IPS is in-line and can introduce delay.
From Andrew Ramdayal's guide:
"IDS monitors and alerts on malicious activity but does not block traffic, making it suitable for environments where low latency is critical."

Once the theory has been tested and confirmed, the next step is to implement the solution based on the CompTIA troubleshooting model.
CompTIA Troubleshooting Model:
Identify the problem.
Establish a theory of probable cause.
Test the theory.
Establish a plan of action and implement the solution. # (Correct step) Verify full system functionality.
Document findings, actions, and outcomes.
Breakdown of Options:
A). Develop a theory - The theory has already been developed and tested.
B). Establish a plan of action - This happens before implementation, but since the issue is confirmed, it's time to act.
C). Implement the solution - Correct answer. The problem is confirmed, so the fix should be applied.
D). Document the findings - Documentation is the final step, not the next one.

To create three subnets with at least 30 hosts each:
Subnet Calculation: Each subnet must support 32 addresses (30 usable + 2 reserved for network and broadcast).
Bits for Subnets: Subnet mask 255.255.255.192 (/26) provides 64 addresses per subnet (4 subnets total).
Valid Subnets: Each subnet provides sufficient IPs to meet the requirement.
255.255.255.128 (A): Creates only 2 subnets, not enough for the requirement.
255.255.255.224 (C): Provides 8 subnets but only 30 addresses per subnet (28 usable), insufficient for hosts.
255.255.255.240 (D): Too restrictive, only 16 addresses per subnet (14 usable).

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.

If the company's SSID is not visible in some areas while other networks are still visible, the most likely cause is insufficient wireless coverage. The wireless signal does not reach those areas, meaning additional access points or signal boosters may be required.
Breakdown of Options:
A: Interference or channel overlap - Would cause slow or unstable connections, but the SSID should still be visible.
B: Insufficient wireless coverage - # Correct answer. If the SSID is not appearing, the signal is too weak in that area.
C: Roaming misconfiguration - Would cause devices to stay on weaker APs instead of switching, but the SSID should still be visible.
D: Client disassociation issues - This would disconnect users, but they should still see the network.
