I just don't see the value of MTCNA being close the cost of the course
Personally I don't see much value in any of IT certifications regardless the vendor ... most of them are very basic level and completing such course doesn't make trainee an expert. And there are many IT professionals without certificates that have much higher knowledge level. But then, if there's a new kid on the block who wants to get some basic knowledge but doesn't have any knowledgeable (informal) tutor at hand, then such trainings are beneficial ... but as you wrote, direct monetary value is probably well below associated cost.
But then there are employers who trip on certificates and if one wants to work for such an employer, getting some certificates is a must.
Maybe is time to check how looks materials and certifications which give you real knowledge ?
As we know, MTCNA is very short / compressed training + cert without network fundamentals.
If someone want know good fundamentals networking then should be interested CompTIA Network+ good training materials or CCNA / JNCIA-Junos (they have very good basic but additionally are focused on their hardware) . The min. real time to learn one of this material is 3 / 6 month and you still don't have practical skills (only lab) . One the best online training portal - https://www.cbtnuggets.com/
offering actual Network+ (20 hours) / CCNA (50 hours) video materials plus access to lab environment / practice exams / Q&A / Quiz / community . And this is only Associate level
. Standard in-place training don't give you this type of knowledge , because they don't have enough time to deep learn (though they can be very good ex. MCTRE). Of course a lot of people try to cheat, they learn only braindumps without real skills and they pass exams . But good employer can verify this type pseudo specialists very fast . Good IT specialist always find job without certificate but if he has enough free time and motivation then why do not try to get it
It's good challenge for him and easier pierce to another job
