// Server status data
const servers = [
{ id: 'web-01', status: 'running', cpu: 45, memory: 67 },
{ id: 'db-02', status: 'stopped', cpu: 0, memory: 12 },
{ id: 'api-03', status: 'running', cpu: 78, memory: 89 },
{ id: 'cache-04', status: 'running', cpu: 23, memory: 45 }
];
// Task: Get names of running servers with CPU < 50%
// Use array methods (filter, map) and return array of server IDs
// Expected: ['web-01', 'cache-04']
function getHealthyServers(servers) {
// Your solution here
}
// Test it - console.log the result
console.log('Healthy servers:', getHealthyServers(servers));// User account validation
function validateAccount(user) {
// Rules:
// 1. Username must be at least 3 characters
// 2. Email must contain '@' and '.'
// 3. Age must be 18 or older
// 4. Account must be active
// Return: { valid: boolean, errors: string[] }
// Your solution here
}
// Test cases
const tests = [
{ username: 'jo', email: 'jo@test.com', age: 25, active: true },
{ username: 'sarah', email: 'invalid-email', age: 17, active: true },
{ username: 'mike', email: 'mike@domain.com', age: 30, active: false }
];
tests.forEach((test, i) => {
console.log(`Test ${i + 1}:`, validateAccount(test));
});// Website traffic calculator
const dailyVisits = [120, 150, 89, 167, 200, 145, 178, 190, 156, 134];
// Calculate:
// 1. Total visits
// 2. Average visits per day
// 3. Highest traffic day (day number, starting from 1)
// 4. Days with above-average traffic
// Return: { total, average, peakDay, aboveAverageDays }
function analyzeTraffic(visits) {
// Your solution here

// Real Angular service method from our cPanel management system

next: (status) => this.serverCache.set(serverId, status),
error: (err) => console.warn('Cache update failed:', err)
});
}
}What happens when this method is called successfully? List the sequence of events.
How are errors handled in this code? What improvements would you suggest?
Explain what each field in the payload represents and why auto_renewal is conditional.
Identify potential issues and suggest 2-3 improvements to make this code more robust.
