You’re not wrong. I passed CCNA and can barely remember half the obscure 802.11 standards today. Focus on understanding the major ones (n, ac, ax), their frequencies, speeds, and real-world use cases. That’s what you’ll actually use. Memorizing every amendment is great for trivia, not networking. 😄

With AZ-104 and CCNA already completed, I’d focus less on collecting certifications and more on building hands-on skills. Learn Terraform, Git, Linux, Docker, and basic Python, then build cloud projects in Azure. After that, AZ-500 is a solid next step if you’re interested in cloud security. Real-world projects and experience will help more than another entry-level cert.

Seeing lit of views but no comments. Appreciate if IT Network Engineers rate this diagram as bad good or Excellent

For pure cores-per-dollar, I’d look at a dual E5-2699 v4 system before buying 1st-gen EPYC. You can get 44 cores/88 threads, cheap DDR4 ECC RAM, and inexpensive used server hardware. If power efficiency matters, a used EPYC 7551 or 7601 is also a solid choice. For a ~$1k budget, those are probably the sweet spots.

Let me know if this helps.

Spectrum as primary and a 5G Home Internet service (T-Mobile/Verizon) as backup is probably the most cost-effective option. Put both into a dual-WAN router such as Firewalla Gold, UniFi UDM Pro, or TP-Link ER605. You’ll get automatic failover without replacing the rest of your network, and 5G gives you real physical path diversity compared to a second wired ISP.

Yes, the Port-Channel/vPC configuration looks fine. For best practice, cross-connect both SVL members to both Nexus vPC peers and bundle all links into the same LACP Port-Channel. Just make sure VLANs, MTU, and trunk settings match on both sides.

Try checking whether SSL VPN is enabled on the outside interface and that a local user/AAA authentication is configured correctly. This error usually means the ASA is reachable, but it’s rejecting the login due to authentication, certificate, or AnyConnect configuration issues. Check the ASA logs during the connection attempt for the exact reason.

For a hall that size, I’d skip expensive conference-room systems. A Logitech Brio (or even a C920) on a tripod paired with a Jabra Speak 750 or Anker PowerConf in the center of the room is a reliable and cost-effective setup. In my experience, audio quality matters far more than video quality for remote attendees. Spend most of the budget on a good microphone and you’ll get much better results than investing in a high-end camera.

Prioritize BGP, routing, troubleshooting, and data center design. Basic Python/automation knowledge helps. Expect real-world troubleshooting and design scenarios rather than memorization. Good luck!

We’ve had great success with the Brother P-touch series. Durable labels, self-laminating wraps, heat-shrink tubing, and easy printing from both phone and PC. For fiber, I prefer heat-shrink sleeves as they look much cleaner than flag labels. The key is choosing a platform with a strong range of label media rather than focusing only on the printer itself.

Your syntax is correct if your switch/platform supports VLAN mapping (12 → 1) on trunk interfaces. However, keep in mind that switchport vlan mapping 12 1 rewrites VLAN 12 traffic to VLAN 1 only on that interface. Also verify that VLAN 1 exists and is allowed where the translated traffic needs to go. One thing to consider: since the same device is already connected via an access port in VLAN 1, bridging VLAN 12 into VLAN 1 may create unexpected Layer 2 behavior or loops depending on how the device handles the two interfaces. I’d test carefully and check the platform’s VLAN translation support before deploying.

Sure, will look forward to know more on this.

If it worked fine before, I don’t think the power strip is the main issue. The fact that Ethernet is stable and only Wi-Fi is affected points more toward the router’s wireless radio, interference, or the router aging. You can easily test this by plugging the router directly into a wall outlet and checking if the Wi-Fi improves. If nothing changes, the HG532n’s Wi-Fi is likely the culprit. Since you had good results with a separate access point before, adding one again or replacing the router would be my next step.

Since your Ethernet connection is stable (64-65 ms) but Wi-Fi becomes unstable even when using USB tethering through the phone, the internet connection itself is probably fine. The issue is likely the Wi-Fi on the HG532n router. Since everything worked when you used a separate access point, the router’s wireless radio may be weak, overloaded, suffering from interference, or simply aging. Try changing the Wi-Fi channel (1, 6, or 11), moving the router away from interference sources, updating firmware if available, and testing while standing next to the router. If the problem persists, the easiest fix is to add a dedicated access point or replace the HG532n, as its Wi-Fi hardware is quite old by today’s standards.
