Of course it is possible to get a job with an A+ certification. It is also possible to get a job with no certification at all. The question you're really asking is if it is possible to get a job with an A+ certification that you wouldn't have gotten without that credential. The answer to that is also 'of course'. There is certainly a job opening out there (probably dozens of them, actually), where the hiring manager would pass on a candidate with no job experience or certifications. but would accept one that had no job experience but that does have an A+ certification.
Is there a job with those specifications going to be open in a region convenient to you on the day after you earn your A+ credential? Heck if I know. There's also the problem that Colin has already noted in his reply. the pay for people with A+ (and nothing else) isn't spectacular.
Pull up jobs in your area on an online job site - Indeed.com is one of my favorites. See if there are companies looking for candidates with A+ credentials in your area and what they pay. If there are some and the jobs interest you, then get the credential. Most likely after you have your A+, a similar set of openings will be available and you can send your resume in.
