I'm just lab this later, but what happens if a router gets a default route that points to itself? Does it just keep bouncing until TTL runs out?

Exact situation was- R1 is connected to R2 via S0/0/0, and has a quad-zero route pointing out S0/0/0. This route is sent out S0/0/0 to R2. fake edit: Just labbed this with a simulator, and R2 automatically drops a packet that contains it's own IP address as a source address. I probably should have known this, but I think the fact that the default route was pointing out an interface, rather than R2's address threw me off. So that's something learned, then.

OK, to conclude this ordeal, if a host on a network connected to R2 (rather than R2 itself) sends a packet with an unknown destination address to R2, the result actually is R2 sending the packet to R1's default route, which sends it back to R2, which sends it to R1's default route, etc until TTL expires- at least, this is what labbing it in Packet Tracer tells me. I did not know that could actually happen, I thought normal OSPF operation generally eliminated routing loops.

I did not know that could actually happen, I thought normal OSPF operation generally eliminated routing loops. It does. However, for lab purposes (in order to mimic real life set up) OSPF doesn't route outside of your network, your ISP doesn't want OSPF traffic. So you can have OSPF handle all your routing needs within your network but you still need a default static route out but if it's configured wrong there can be issues. Also, is it the entire packet that's getting forwarded to R1 or some other protocol? And when you say unknown address, what do you mean?

# ? Apr 25, 2014 02:11 |

By "unknown destination address", I mean that it isn't in R2's routing table (other than the quad-zero default address learned from R1). In Packet Tracer, I was just generating traffic with ICMP pings sent from a host connected to R2 with a random unicast destination IPv4 address that isn't in the routing table.

In my experience both the actual test questions and the practice test questions had varying degrees of difficulty, so this is a hard question to answer. I'd say Odom's practice tests are generally easier because the questions aren't as involved or interactive as a question you would see in the actual testing environment. Pearson would do well to add some interactivity to their practice test engine, but I won't hold my breath.

Is there anything I really should worry about emphasising while prepping for the A+ Exam? Hardware related questions seem to come quite easily to me, and i'm not doubting software will be any different. I'm more concerned about things like "How wide is the standard floppy disk" , "name several different voltages your power supply uses" type deals.

assuming I pass the CCNA on Tuesday, I will be in the position for applying for networking jobs with very little knowledge of enterprise wireless equipment, or MPLS (which shows up in pretty much every telecom network position I see). I did purchase the CCNA Wireless book (not really looking for the cert, just looking to skim through it so I don't totally embarrass myself if someone asks me to configure a wireless router), but can anyone recommend reading on MPLS? (I assume that's what Cisco CCNA SP covers, but that one has no cert guide associated with it).

Ha, that was just what I came to the thread to ask! To follow up, the course is 5.1, but the latest version of the book by Scott Lowe is 5.5. I get the impression that the course will let me sit the 5.1 or 5.5 cert. People seem to think the 5.1 cert is the easier test? Should I get the 5.5 book anyway?

I'm studying for my Windows 2012 MCSA - one of them I've come across is DHCP and how it may be a security risk and assigning addresses statically is more secure. My question, does anyone actually do this? I know it's a best-practice or literally required to assign static IPs to servers but for other endpoints? That's just a managerial nightmare, I can't imagine any big company or even governmental organizations implementing this... I don't see how it could be that big of a risk either, it's not like someone can't just assign an IP to rouge device either...

Most companies will have a range of IPs in a specific subnet to reserve for printers/routers/servers, the rest would be DHCP, it doesn't seem like it would be that hard as long as you have your stuff mapped and tracked proper. Setup for that first time would be a bitch sure, but once it's done......

Maybe there's better ways to do it, but I'm guessing that for your ultra-secure network of servers that would literally destroy the company if they were compromised, use Static IPs. For the branch office in Wyoming, DHCP should be ok. For stuff in between... I'm not sure.

There are solutions from other vendors that implement security much better such as port shielding or deactivating unused patches. Keep it in mind for the exam, but know that there are better solutions in the wild and in production that will intelligently react to users changing up end devices, implementing their own switches/wireless

I'm trying to decide between an MCSA in Windows Server vs SQL Server. It seems there's a lot of overlap in the jobs I've looked at, and I've also read that sys admin is a good path to become a DBA, which means it would make more sense to do Windows Server to qualify me to be a sys admin, even though I think ultimately I'd prefer to be a DBA. So I'm really not sure which path to take. At the moment I'm trying to switch careers into IT, I currently have A+ and I'm hunting for a tech support job to get started. I have some experience with SQL and it definitely clicked with me in a way that programming never did. Can anyone advise me?
