Week 28 Summary

Week 28 à “An exciting future for me and my family lies ahead”

Week’s Study Time: Study Hours = 8 inc. Lab Hours = 0 Total study time so far: Total Study Hours = 329  inc. Total Lab Hours = 20.5 What I have studied during the last 2 weeks: EIGRP OSPF Recent test scores: Boson ExSim tests…

 

I’ve completed my second day at Cisco today, and I’ve been incredibly impressed with how streamlined everything is here!  Everything is in place just to let you get on with what you are employed to do – no distractions, and they really look after you 🙂

Everybody I have come into contact with so-far has been very pleasant and has gone out of their way to help me, glancing around the canteen/restaurant during lunch makes me realise I’m in the company of some of the sharpest minds in the industry – quite intimidating (I’ve been told that is a normal feeling to have – especially with the surroundings @ Bedfont Lakes).

 

I had this idea in my head at the beginning of this week (29) that I would be able to continue studying during my first few days at Cisco – how wrong was I!  You wouldn’t believe how many systems I need to get setup on, not to mention the amount of “New-Hire” and “SE” information I need to read through, unfortunately, studying is going to have to take a back-seat for a little while.  Starting a new job and CCIE level studying just don’t go-together 😦

Realistically, I think I should be aiming to pick-up where I left things next week, and that may possibly cause me to take a look at my written exam date again….
(Although, I will have to ask myself how many times I will allow myself to put the date back? – once so far)

 

Here are a couple of great links thatI have come-across within the Cisco ‘blogosphere’ over the last few days:
1) EBGP Load Sharing @ the NIL Wiki
2) Integrated Routing and Bridging Example @ Cisco Network Engineer

 

And, here are a few sample questions from my workbook, why not test yourself?
I’ll give you an idea of what is being covered by these questions –> 1) = Process Switching…

1) Router Switching Path/Method Option 1
1a) The {“item”} computes the CRC

2) Router Switching Path/Method Option 2
2a) The {“item”} computes the CRC (except the first packet)
2b) Entries are added to the {“item”}
2c) What form of load balancing is the only one supported?
2d) Which command enables this switching method on an interface?

3) Router Switching Path/Method Option 3
3a) Creates a copy of the routing table called the {“name”}
3b)  What is the arrangement of the table above called?
3c) Pointers to the {“item”} are added to the table above
3ca) Entry type 1 in this table
3cb) Entry type 2 in this table
3cc) Entry type 3 in this table
3cd) Entry type 4 in this table
3ce) Entry type 5 in this table
3cf) Unknown information entry description in this table
3d) Both tables reside on the route processor (RP) and are stored in {“location”}
3e) What is the command to enable this switching method globally?
3f) What is the command to enable this switching method on an interface?
3g) What is the default load balancing method for this switching method?
3h) If configured on an inbound int, the packet {will | will not} always be switched in the same way on the outbound int

Scroll down for my answers (correct or not)……

I’m going to apologise in advance –> expect to hear even less from me over next couple/few weeks (nothing out of the ordinary their then!)
