Refer to the exhibit. What is the most likely cause of this failure?
2A junior administrator configured a new network interface (ens224) with a static IP address using a configuration file in /etc/sysconfig/network-scripts/ifcfg-ens224. After restarting the network service, the interface comes up but does not get the IP address. The administrator runs 'ip addr show ens224' and sees no IP address assigned. The interface is listed as DOWN. The administrator then runs 'ifup ens224' manually, which succeeds, and the IP address appears. What is the most likely cause?
3A system administrator is troubleshooting a custom service called 'database.service' that fails intermittently. The service is a proprietary database that requires large amounts of memory. The administrator runs systemctl status database and sees 'Active: failed (Result: core-dump)' and the journal shows 'Out of memory: Killed process (database) total-vm:...' The server has 8GB RAM and 2 CPU cores. The service unit file does not contain any memory limits. The application is configured to use up to 4GB. The administrator suspects the systemd service is being killed by the OOM killer. Which action should the administrator take to prevent this issue?
