Mock Exam

Q1. The metric node_cpu_temp_celcius reports the current temperature of a nodes CPU in celsius. What query will return the average temperature across all CPUs on a per node basis? The query should return {instance=“node1”} 23.5 //average temp across all CPUs on node1 {instance=“node2”} 33.5 //average temp across all CPUs on node2.

node_cpu_temp_celsius{instance="node1", cpu="0"} 28
node_cpu_temp_celsius{instance="node1", cpu="1"} 19
node_cpu_temp_celsius{instance="node2", cpu="0"} 36
node_cpu_temp_celsius{instance="node2", cpu="1"} 31

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

1. Use ESM yourself. (preferred)
   Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
3. Stay on the existing version of the package until you can move to ESM.

Problem

I've recently been hacked on my VPS(using Centos 7.6 and CWP up to date) and the following files/folders were created:

• /tmp/.ICEd-unix
• /var/tmp/.ICEd-unix
• /tmp/kdevtmpfsi
• /var/tmp/kinsing

The following processes were running and using 100% CPU and Memory:

#!/usr/bin/env bash

if [ $# -eq 0 ]; then
  echo "Needs the filename as the first argument"
  exit -1
fi

type /usr/local/bin/convert >/dev/null 2>&1 || { echo >&2 "The convert command must be available."; exit 1; }

input_filename="${1}"
