Everyone which one you used daily?

@Saanvi_dhillon 16GB

as a developer, how much RAM is enough? 1. 4 GB 2. 8 GB 3. 16 GB 4. 24 GB 5. 32 GB 6. 64 GB+

Docker Image vs Container • Images are immutable blueprints • Containers are disposable runtime instances • Fix the Dockerfile, not the container This mindset is what makes deployments reproducible. #Docker #DevOps #Cloud #Kubernetes

@aarivCodes 16Gb is enough

As a developer, how much RAM is enough for you? 1. 4 GB 2. 8 GB 3. 16 GB 4. 24 GB 5. 32 GB 6. 64 GB+

@cyber__razz fork bomb

Write something only a Linux user can understand

@suni_code Because compression costs time and CPU, and data is usually written for speed first not optimization.

@ankit_ops2799 But why don't we do that from the start

Interviewer: A 5GB file shrinks to 1.2GB after compression No Data lost, no quality degraded. If nothing is lost, what exactly is compression eliminating?🤔

@javarevisited Because container shares the host OS kernel, so it avoids full VM overhead but it still carries everything your app needs to run. container itself is lightweight but the image can still be huge.

Interviewer: If Docker containers are lightweight, why are some containers still hundreds of MBs?

@SakshiSugandhi Jira

Which is the best project management tool?

@CyberRacheal Quick Format deletes the index, not the data itself. The files stay on the USB until overwritten.

Interviewer: A user performs a 'Quick Format' on their 32 GB USB drive, thinking they have wiped all their data. However, a technician is later able to restore 100% of those files. Where exactly was that data stored during the period the drive appeared empty, and why did the formatting process fail to remove it? 🤔

@CyberRacheal C. 10.0.0.50 It belongs to the 10.0.0.0/8 private range, which supports millions of internal hosts.

A network administrator is setting up a large corporate office and needs a private IP range that supports over 65,000 internal hosts. Which address should they use? A. 192.168.10.5 B. 172.16.50.100 C. 10.0.0.50 D. 127.0.0.1

@Sarthak4Alpha Pause autoscaling, stop failing pods, then inspect pod events/logs. Since no code changed, there can be possibilities of infra issues like bad probes, expired secrets, dependency outages, or resource exhaustion.

Interviewer: 80% of your pods are stuck in a crash loop. Your cluster autoscaler panics, scaling from 12 to 47 nodes in 20 minutes. Pods boot up, live for 90 seconds, get killed, and repeat. Your AWS bill is jumping $400/hour. And the worst part? You haven't deployed ANY new code today.

@SidJain_80 By using object storage and CDN

Interviewer: Millions of images are uploaded daily. How do you store and serve them efficiently?

@FirozCodes Firefox

Which one is your default Browser? mine is brave..

@TechByTaraa VS Code is best

be honest, which IDE is the best right now?

The correct answer is: 2️⃣ Memory (RAM) Why? CPU is compressible → Kubernetes/Linux can throttle CPU usage, slowing containers down while they continue running. Memory is incompressible → Once RAM is exhausted, the system cannot throttle it safely. If a Pod exceeds memory limits or the node runs out of RAM: Kubernetes may trigger an OOMKilled The Pod can be evicted immediately CPU → Throttled under pressure Memory → Hard limit, causes eviction/OOM Disk I/O → Can slow down workloads Network bandwidth → Causes latency/congestion In short: CPU pressure slows Pods down. Memory exhaustion kills them

@uday_devops COPY → used for most file transfers (recommended) ADD → used only when you need auto-extraction or URL fetching Use COPY unless you specifically need ADD features.

Interviewer: What is the difference between COPY and ADD in Dockerfile?
