Exam N10-009 topic 1 question 1 discussion

Port enabled = connected devices Port disabled = no devices LACP enabled = if connected from switch to switch untagged VLAN = devices connected (servers, pc, printer...) tagged VLAN = if connected from switch to switch Should be pretty straightforward with that info.

After reviewing some outside notes and doing this on paper, I think the answer is this below. Correct me if anything may be wrong though: SWITCH 1: - The only thing that would need to be fixed here is to set all the Speed and Duplex values to auto. - All LACP, tagging, and VLAN assignments look to be correct. SWITCH 3: - For all ports, set Speed and Duplex to auto (although I guess disabled ones don't matter as much). - For all ports, remove from VLAN 1 (although, again, disabled ports might not matter as much). - Port 1 and Port 2: * Enable port * Enable LACP * Add following VLANS as TAGGED: 60, 90, 120, 220 - Port 3: * Disable port - Port 4: * Add to VLAN 220 TAGGED * Add to VLAN 120 untagged - Port 5: * Disable port - Port 6: * Add to VLAN 120 untagged - Port 7: * Add to VLAN 60 untagged - Port 8: * Add to VLAN 90 untagged

Had one that looked EXACTLY like this yesterday, saved this for last, ran out of time, unless you have muscle memory of doing this and under pressure you're going to spin your wheels I burned 10 min on this one. You get a black terminal screen that's it. When you type "help" you see 4 commands the interfaces, arp, mac address table, and vlan... So if you really want to pass this one I would suggest you have to make a fake topology on cisco with that free tool they have and then practice, looking at how to find the mac, how to find the IP, how to find what interface and what vlan the PCS, swtich, router they give you are using/on/connected. Or you can just screw it, bomb it, and still pass if you do good on the other questions. Best of luck. Memorize "Exotic Indian Oval Rubies" 90 EIGRP, 100 IGRP, 110 OSPF, 120 RIP. Thank me later.

This question appeared on the exam I took on May 12, 2025, but with different information; however, the format was the same.

One half says to leave speeds at 1000, other side says to change to Auto. Any tie breakers here?

Oh I screwed up. Should just be replying to myself, instead of posting new. OK, I'll redo. Sorry guys.

For VLAN tagging, looks like on access-distribution trunk links, they only want VLANs that the access switches are using. Dist-core trunk links will need to carry all VLANs. You only tag VLANs on trunk links. Never on the ports endpoints are plugged into.

LACP should be enabled on all the trunk ports: Core switchports 1, 2; Switch 1 ports 1, 2, 5, 6, 7, 8; Switch 2 ports 1, 2; Switch 3 ports 1, 2

Looks like Switch 1 is a distribution layer switch with two servers hanging off of it Switch 2 and 3 are access layer switches.

Unless scenario indicates a speed/duplex mismatch, leave all ports on all switches at Full / 1000 (IRL we would set these to auto/auto)

Old CCSI here. I'll have to post response in chunks. Wasn't able to respond in one post. First: Disable Core switchports 3 - 8, Switch 2 port 6, Switch 3 ports 3, 5
