Is CompTIA Network+ worth it in Buenos Aires?
At $358 USD for the exam and a three-year renewal cycle, CompTIA Network+ delivers strong ROI for Buenos Aires-based professionals. With the average IT salary in the city sitting around $28,000/yr, the documented salary uplift of approximately $6,000/yr means the certification can pay for itself within weeks of landing a new role or negotiating a raise. That's a return of roughly 1,575% over the three-year certification period on the exam cost alone. Buenos Aires has a competitive but credential-hungry IT job market — holding Network+ differentiates you from uncertified candidates and opens doors to roles that explicitly require a recognized networking qualification.

- 1.Do not skip performance-based questions (PBQs) during practice — they appear first on the real exam and can eat your time budget. Practice flagging them and returning if needed, but attempt every one.
- 2.Memorize the well-known port numbers (20/21 FTP, 22 SSH, 23 Telnet, 25 SMTP, 53 DNS, 67/68 DHCP, 80 HTTP, 443 HTTPS, 3389 RDP) — the N10-009 exam tests these directly and repeatedly.
- 3.Know the CompTIA troubleshooting methodology's seven steps in exact order — the exam will present troubleshooting scenarios and expect you to identify the correct next step, not just a valid one.
- 4.Study the differences between STP, RSTP, and how VLANs are configured and trunked — switching concepts are heavily weighted in N10-009 and frequently appear in both multiple-choice and PBQ formats.
- 5.For wireless questions, know which 802.11 standard operates on which frequency bands, maximum theoretical speeds, and the security differences between WEP, WPA, WPA2 (AES/TKIP), and WPA3 — these details are tested at the specific, not conceptual, level.
