A system administrator manages software permissions, service ports, credential vaults, and system processes across macOS and Linux endpoints in an enterprise environment. Match each CLI command or native operating system utility on the left with its exact administrative function or outcome on the right.
- chmod 750 /scripts/backup.shGrants read, write, and execute access to the owner; read and execute to the group; and no access to others.
- Keychain AccessNative macOS management utility used to store user passwords, private keys, certificates, and secure notes.
- lsof -i :8080Lists open files and active process details bound specifically to TCP/UDP port 8080.
- kill -9 4152Sends an uncatchable SIGKILL signal to forcibly stop process ID 4152 immediately.
Cevap
chmod 750 /scripts/backup.sh matches granting rwx to owner, r-x to group, and no access to others. Keychain Access matches the native macOS security utility for passwords and certificates. lsof -i :8080 matches listing open files and processes bound to port 8080. kill -9 4152 matches sending an uncatchable SIGKILL signal to forcibly terminate PID 4152.
Each tool or command accurately matches its system function: chmod 750 assigns permissions by user tier (owner: rwx, group: r-x, others: none); Keychain Access manages macOS encrypted credentials; lsof -i :8080 inspects network-bound processes on port 8080; and kill -9 sends a SIGKILL signal to forcibly terminate the specified PID.
