2.0 for me but I am using it only as an overview for now, loads of info repeats which is great and helps with retaining.

tip: For the one's who change web hosting providers, change TTL low or add both service providers DNS before shifting for downtime reasons. ❤

this comes with newest a+? seems like more network+ material

@Baronvontrap 2 жыл бұрын

It's a part of A+ since the fundamental knowledge base is pretty broad.

Check the exam objectives, everything he covers mirrors those.

10:00 out of curiosity, what does the "300" do in your SPF statement?

@arctic8567 Жыл бұрын

It's the TTL measured in seconds, so 300 would be 5 minutes. Founds this with a google search "The TTL indicates how long until your computer, or resolver has before it should recheck with the authoritative nameserver. For example if you set the TTL to be 5 minutes it would take 5 minutes for all the computers in the world to use your new setting."
