She passed with a 932.
Joaquín smiled. “Because it forces you to fail before you succeed. Now go home. Open Packet Tracer. Start with Lab 1.1. Do not move to Lab 1.2 until you see the words ‘PING successful.’”
Elena followed the steps exactly. She configured the Gig0/0 interface on the router, set the VLANs on the switches, and even remembered to issue no shutdown . She typed the ping command.
Her mentor, a retired network engineer named Joaquín, noticed her frustration. He didn't hand her a thick textbook. Instead, he slid a worn USB drive across the table.
“This is just a PDF,” she sighed. “How will this help?”
!!!!! Success rate is 100 percent.
She spent four hours debugging a routing loop between three routers. At 2:00 AM, she realized she had forgotten to configure passive-interface on the loopback. The moment she fixed it, the routing table converged.
On exam day, the proctor handed her a scratch sheet. The first simulation question was a disaster: a broken EIGRP configuration with mismatched AS numbers. Her hands didn’t shake. She had done this exact fix in Lab 5.3 of the Guia de Laboratorios .
“Forget the theory for a while,” Joaquín said. “Inside that drive is a file: Guia_de_Laboratorios_CCNA_200-301_v7.1.pdf . It’s not a novel. It’s a map.”
Years later, when a new intern asked how to prepare for the CCNA, Elena smiled. She handed over the same PDF— Guia de Laboratorios CCNA 200-301 Versión 7.1 —and said the same words Joaquín once told her:
