Which of the following steps in the troubleshooting theory should be performed after a solution has been implemented? (Choose two.)

A. Escalate the issue
B. Document the findings
C. Notify the users
D. Develop a plan of action
E. Scope the issue
F. Perform a root cause analysis

正解：B、C

解説：
The steps in the troubleshooting theory that should be performed after a solution has been implemented are document the findings and notify the users. The troubleshooting theory is a systematic process of identifying and resolving problems or issues with a system or device. The troubleshooting theory consists of several steps that can be summarized as follows:
Identify the problem: Gather information, scope the issue, establish a theory of probable cause.
Establish a plan of action: Test the theory, determine next steps, escalate if necessary.
Implement the solution: Execute the plan, verify functionality, prevent recurrence.
Document the findings: Record actions taken, outcomes achieved, lessons learned.
Notify the users: Communicate resolution status, confirm satisfaction, provide follow-up.
Documenting the findings is an important step that helps create a record of what was done and why, what worked and what didn't, and what can be improved or avoided in the future. Documenting the findings can also help with reporting, auditing, compliance, or training purposes. Notifying the users is another important step that helps inform the affected parties of what was done and how it was resolved, confirm that the problem is fixed and that they are satisfied with the outcome, and provide any follow-up instructions or recommendations.

質問 # 22
A datacenter in a remote location lost power. The power has since been restored, but one ol the servers has not come back online. After some investigation, the server is found to still be powered off. Which of the following is the BEST method to power on the server remotely?

A. Crash cart
B. Out-of-band console
C. IP KVM
D. RDP

正解：B

解説：
Out-of-band console is a tool that can be used to command a remote shutdown of a physical Linux server. Out-of-band console is a method of accessing a server's console through a dedicated management port or device that does not rely on the server's operating system or network connection. Out-of-band console can be used to power cycle, reboot, update firmware, monitor performance, and perform other tasks remotely even if the server is unresponsive or offline. Crash cart is a mobile unit that contains a keyboard, monitor, mouse, and other tools that can be used to troubleshoot a server on-site, but it requires physical access to the server. IP KVM (Internet Protocol Keyboard Video Mouse) switch is a hardware device that allows remote access to multiple servers using a web browser or a client software, but it requires network connectivity and may not work if the SSH connection is lost. RDP (Remote Desktop Protocol) is a protocol that allows remote access to a Windows server's graphical user interface, but it does not work on Linux servers and requires network connectivity.

質問 # 23
Which of me following is the BEST action to perform before applying patches to one of the hosts in a high availability cluster?

A. Failover all VMs.
B. Set the cluster to active-active.
C. Fallback cluster services.
D. Disable the heartbeat network.

正解：A

解説：
This is the best action to perform before applying patches to one of the hosts in a high availability cluster. A high availability cluster is a group of hosts that act like a single system and provide continuous uptime. A high availability cluster is often used for load balancing, backup, and failover purposes. Failover is a process of transferring workloads from one host to another in case of a failure or maintenance. By failing over all VMs (Virtual Machines) from the host that needs to be patched to another host in the cluster, the technician can ensure that there is no downtime or data loss during the patching process. Disabling the heartbeat network is not a good action to perform, as this would disrupt the communication and synchronization between the hosts in the cluster. Fallback cluster services is not a valid term, but it may refer to restoring cluster services after a failover, which is not relevant before applying patches. Setting the cluster to active-active is not a good action to perform, as this would increase the load on both hosts and reduce redundancy.

質問 # 25
An administrator is troubleshooting a failure in the data center in which a server shut down/turned off when utility power was lost The server had redundant power supplies. Which of the following is the MOST likely cause of this failure?

A. The UPS batteries were overcharged.
B. Redundant power supplies require 220V power
C. Both power supplies were connected to the same power feed
D. The power supplies were not cross-connected

正解：C

解説：
The most likely cause of this failure is that both power supplies were connected to the same power feed, which means that they both lost power when utility power was lost. To prevent this from happening, redundant power supplies should be connected to different power feeds, preferably from different sources, such as a UPS or a generator. Verified Reference: [Redundant Power Supply Best Practices]

質問 # 27
A server administrator receives the following output when trying to ping a local host:

Which of the following is MOST likely the issue?

A. VLAN
B. DNS
C. Firewall
D. DHCP

正解：C

解説：
Explanation
A firewall is a network device or software that filters and controls the incoming and outgoing traffic based on predefined rules. A firewall can block or allow certain types of packets, ports, protocols, or IP addresses. The output of the ping command shows that the local host is unreachable, which means that there is no network connectivity between the source and the destination. This could be caused by a firewall that is blocking the ICMP (Internet Control Message Protocol) packets that ping uses to test the connectivity. References:
