Which of the following is typical of software licensing in the cloud?
Subscription-based licensing is the most typical model in the cloud, as it offers flexibility and scalability for users. It allows customers to pay for services on a regular basis (monthly, annually), which aligns with the on-demand nature of cloud services. This model contrasts with traditional software licensing models such as per socket, perpetual, or site-based licenses, which do not effectively accommodate the dynamic and scalable environment of the cloud.
A server administrator wants to run a performance monitor for optimal system utilization. Which of the following metrics can the administrator use for monitoring?
(Choose two.)
In order to run a performance monitor for optimal system utilization, it is crucial to monitor the key hardware resources that impact performance the most. Memory and CPU are two of the most critical metrics because they directly affect the system's ability to handle tasks. Monitoring memory helps ensure there is enough random access memory (RAM) available for processes to run efficiently, whereas monitoring CPU usage helps determine if the processor is overloaded or underutilized, thereby directly impacting the system's responsiveness and processing capacity.
After configuring IP networking on a newly commissioned server, a server administrator installs a straight-through network cable from the patch panel to the switch. The administrator then returns to the server to test network connectivity using the ping command. The partial output of the ping and ipconfig commands are displayed below:
The administrator returns to the switch and notices an amber link light on the port where the server is connected. Which of the following is the MOST likely reason for the lack of network connectivity?
The amber link light on the switch port typically indicates an issue with network port security. When port security is enabled on a switch and a violation occurs, the port can be disabled or placed in a restricted state, resulting in a status light turning amber. While other factors like VLAN configuration or NIC misconfiguration could cause connectivity problems, the specific mention of an amber light highly suggests port security as the primary issue. The IP configuration on the server seems correct, making network port security the most likely cause of the connectivity issue.
A user cannot save large files to a directory on a Linux server that was accepting smaller files a few minutes ago. Which of the following commands should a technician use to identify the issue?
The command 'df -h' is used to display the disk space usage on all mounted filesystems in a human-readable format. It is particularly useful in this scenario where the user is unable to save large files, as it will show the available disk space on the relevant filesystem. This helps to identify if the issue is due to the filesystem being full.
Following a recent power outage, a server in the datacenter has been constantly going offline and losing its configuration. Users have been experiencing access issues while using the application on the server. The server technician notices the date and time are incorrect when the server is online. All other servers are working. Which of the following would MOST likely cause this issue? (Choose two.)
The server consistently going offline and losing its configuration, along with incorrect date and time, strongly suggests a CMOS battery failure. The CMOS battery helps retain BIOS settings, including the system clock, when the server is powered off. Additionally, if the time synchronization service (such as NTP) is disabled on the server, it could lead to incorrect time, further contributing to access issues. This explains why the date and time are incorrect when the server is online. Therefore, a CMOS battery failure and a disabled time synchronization service are the most likely causes of this issue.
