Hi Jeremy, I just passed the CCNA exam a few days ago. I used your Anki cards extensively in my studying. They are well-made cards, easy to study and clear, covering a lot of important details. I also made my own cards, about 2700. Anki and Boson practice exams helped me pass CCNA on the 1st try. I scored 745, 890, 925 on Boson exams (1st attempt) and 900 on the real CCNA exam. So thank you for your Anki cards and for recommending Boson practice tests. I can't wait for your CCNP course. I am taking a short break and start my CCNP study soon.

23:03 "should be changed regularly", I'm sure Jeremy knows that but just for a broader audience: NIST actually does NOT recommended to change passwords regularly as it tends to get people to go for easy to remember and therefore weaker passwords. Machine generated passwords (and therefore password managers) would be the ideal recommendation.

Something about ssh and vlans is confusing me. I keep trying and getting it wrong. If I have multiple vlans on a switch, do I need to put the management intfc vlan as native so that ssh traffic isn't blocked/tagged? If I have multiple vlans and subnets, which IP default-gateway do I assign on the switch? Do I have to just use different int vlans for each subnet (if I did that, can't I only config 1 default gateway on the switch in global config)? Trying to sort this out has had me puzzled for a very long time. Thanks to any.

@JeremysITLab 3 жыл бұрын

Yep, just different ways to say it

@xakirakunx 3 жыл бұрын

Hi Jeremy, since DHCP exhaustion happens by taking up all the IP addresses in the DHCP pool, would it be right to say that if the network is configured with PAT / NAT overload, this is not a risk to the network?

@JeremysITLab 3 жыл бұрын

It will still be a risk. Even if PAT is configured to allow communication over the Internet, the host still needs to be able to get a private IP address from the DHCP server.

For instance, I tap notifications all the time but it doesn't really accomplish an action. Perhaps a rewording would be better. Just a suggestion and maybe I'm the only person that had that problem??
