Yes. Mediapartners-Google follows robots.txt, so a Disallow rule for the Mediapartners-Google user agent stops it from crawling the paths you list.
Add "User-agent: Mediapartners-Google" followed by "Disallow: /" to the robots.txt file at the root of your site. To enforce it, block requests whose user agent contains "Mediapartners-Google" at your WAF. In Transfon Security that is one User Agent block rule.
No. robots.txt is voluntary, so Mediapartners-Google may not follow it, and anyone can send Mediapartners-Google's user agent, so a fake Mediapartners-Google ignores your rule. Enforce the rule where requests arrive, at your WAF, and check the source network.
Run a reverse DNS lookup on the IP. Genuine Mediapartners-Google IPs resolve to a hostname ending in googlebot.com, and a forward lookup of that hostname returns the same IP. Anything else using its user agent is an impersonator.
