질문 # 478
A network administrator needs to securely connect to an Ubuntu server for management purposes. Which of the following protocols will most likely address this requirement?

정답：C

설명：
SSH (Secure Shell) is the standard and most secure protocol for remote command-line access and management of Linux-based systems, including Ubuntu servers.
HTTPS is used for secure web traffic, not direct server management. SFTP runs over SSH but is used for secure file transfers, not server administration. RDP (Remote Desktop Protocol) is primarily for Windows systems, not Ubuntu/Linux.
SSH is the correct protocol for securely managing an Ubuntu server.


질문 # 479
Which of the following offers the ability to manage access at the cloud VM instance?

정답：C


질문 # 480
A network technician needs to resolve some issues with a customer's SOHO network.
The customer reports that some of the devices are not connecting to the network, while others appear to work as intended.
INSTRUCTIONS
Troubleshoot all the network components and review the cable test results by Clicking on each device and cable.
Diagnose the appropriate component(s) by identifying any components with a problem and recommend a solution to correct each problem.






Cable Test Results:
Cable 1:

Cable 2:

Cable 3:

Cable 4:







정답：

설명：
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 troubleshoot all the network components and review the cable test results, you can use the following steps:
* Click on each device and cable to open its information window.
* Review the information and identify any problems or errors that may affect the network connectivity or performance.
* Diagnose the appropriate component(s) by identifying any components with a problem and recommend a solution to correct each problem.
* Fill in the remediation form using the drop-down menus provided.
Here is an example of how to fill in the remediation form for PC1:
* The component with a problem is PC1.
* The problem is Incorrect IP address.
* The solution is Change the IP address to 192.168.1.10.
You can use the same steps to fill in the remediation form for other components.
To enter commands in each device, you can use the following steps:
* Click on the device to open its terminal window.
* Enter the command ipconfig /all to display the IP configuration of the device, including its IP address, subnet mask, default gateway, and DNS servers.
* Enter the command ping <IP address> to test the connectivity and reachability to another device on the network by sending and receiving echo packets. Replace <IP address> with the IP address of the destination device, such as 192.168.1.1 for Core Switch 1.
* Enter the command tracert <IP address> to trace the route and measure the latency of packets from the device to another device on the network by sending and receiving packets with increasing TTL values.
Replace <IP address> with the IP address of the destination device, such as 192.168.1.1 for Core Switch 1.
Here is an example of how to enter commands in PC1:
* Click on PC1 to open its terminal window.
* Enter the command ipconfig /all to display the IP configuration of PC1. You should see that PC1 has an incorrect IP address of 192.168.2.10, which belongs to VLAN 2 instead of VLAN 1.
* Enter the command ping 192.168.1.1 to test the connectivity to Core Switch 1. You should see that PC1 is unable to ping Core Switch 1 because they are on different subnets.
* Enter the command tracert 192.168.1.1 to trace the route to Core Switch 1. You should see that PC1 is unable to reach Core Switch 1 because there is no route between them.
You can use the same steps to enter commands in other devices, such as PC3, PC4, PC5, and Server 1.


질문 # 481
Which of the following steps is part of the decision-making process for a Change Advisory Board (CAB) when evaluating a change?

정답：A

설명：
When dealing with troubleshooting and change management, the plan of action outlines the steps, risks, and mitigation strategies. A change advisory board (CAB) uses this documented plan to decide whether to approve the change.
* A. Identify the problem is the first step in troubleshooting, not decision-making for CAB.
* B. Develop a theory is diagnostic work, not planning.
* C. Test the theory confirms causes but doesn't provide actionable planning information.
References (CompTIA Network+ N10-009):
* Domain: Network Operations - Change management, troubleshooting methodology, CAB processes.


질문 # 482
A global company has acquired a local company. The companies are geographically separate.
The fully utilized IP address ranges for the two companies are as follows:
- Global company: 10.0.0.0/16
- Local company: 10.0.0.0/24
Which of the following can the network engineer do to quickly connect the two companies and minimize user disruption?

정답：A

설명：
Because the two organizations use overlapping IP space, direct routing will not work. Assigning a NAT range to the local company allows immediate connectivity by translating the overlapping addresses, avoiding the disruption of renumbering the entire local company.
