Which do you think looks better - a 2.6 GPA, or a 2.6 GPA and having earned a CCNA?
Some employees just flag keywords and having CCNA will get you a few hits for that reason alone. It also gives you a foot in the door to address your interests and to offer any explanation you may want to give for your grades. Maybe you’ve had family or life difficulties or you’ve struggled with physical or mental illness. You can take the chance in an interview to explain how you had some difficulty but then you chose to dedicate the last several months to study and earn the CCNA. I think that will go a good way towards demonstrating to an employer that you are motivated and willing to work.
