  3. These are all questions I remember from taking last week. I wrote them down as soon as I left, in the car. Actually, quite a few from 404Q, but I forgot a lot of them while taking test. Memorizing is not as reliable, haha. Was close to passing, but some of the security questions threw me off. Taking again in 2 wks, will def pass. LOTS of: H-VPLS, VPLS (MACs) MPLS L3VPN (including multicast) MPLS-TE/RSVP-TE (Autoroute, Priority, shared explicit style - flows share resources) IPv6 (multicast, MLD, 6PE, SLAAC) Multicast DMVPN/GETVPN/other tunnels (w/ IPv6, multicast) IS-IS LFA Voice - jitter, congestion OSPF (KNOW Partial SPF vs. Incremental vs. Full, carrier delay, LSA arrival timer, etc.) Best Questions: (Some of these might be in the 404Q or 314Q, etc., but I forgot. I am human, haha.) Q1: B-------D / \ \ A \ F \ \ / C------E A-B, B-D, D-F = all 100M links A-C, C-E, E-F, and B-E link = 200M links Choose 2 links to lower cost. Also be ready to answer if they ask 'increase cost.' - IF improve links (lower cost), I choose A-C and C-E, to make sure B-E link isn't taken (avoid B-E, B-E is 200M, BUT is in suboptimal path). - IF increase cost, choose B-E and B-D (or other 100M link). *Not exact diagram, but the basic topology is correct. I remember that much. Q2: 2 DCs, L2 tunnel (I think), CPU is affected. Choose two. A: - block BDPU at Routers A and B - block BDPU at Switches C and D (may be wrong if they mean BPDU Guard to block) - filter BDPU at Switches C and D (chose) - filter BDPU at Routers A and B - create DCI betw DCs (maybe this) Q3: STP Root Guard? A: Prevent Suboptimal routing (other answers describe loop guard or UDLD or PortFast concepts) Q4: EIGRP metric Q (longish, but not very relevant, due to easy answer) A: Delay, BW (easy one) Q5: Cost 10 and 20 links, how would router decide which interface to take? A: - RIB (Actually, I like this better, due to wording of Q) - FIB Q6: Simple/basic Layer 2 separation? (This this is in 404Q already or other, oh well.) A: - VLAN (chose) - switched port - routed port - SVI Q7: Same multicast source IP, two labs getting connected? A: - not supported (wrong) - requires unique RP (dont see any use of this) - requires filtering (leaning towards this, two domains) - is supported <-- Best answer, IF Cisco is talking about same Application traffic from both labs. (It said "there would be a problem otherwise" though, which was VERY misleading, if they want THIS answer.) Q8: Big SP, multiple sources, which mode? A: - SSM (chose) - Bidir Q9: 10G/40G, Core sometimes congested, Internet Gateway 1 Gbps, where Deep Packet Inpection? A: - WAN - Internet Gway (avoid affecting congested links, DPI of Internet traffic only) - Core (if want investigate congestion) - DC - Access Q2 - not sure how they mean to block/filter BPDU at routers, so I didn't choose those options. Q5 - I went w/ 'deciding factor' (what int to go out of is according to RIB) vs. HOW it looks up what int to go out of (FIB). Q7 - "There is always the consideration of joining two PIM domains but this could be solved by using static joins at the edge and implementing data plane filtering." [Hidden Content] This sounds like a perfect solution, but it may be better to go w/ plain old 'it just works' option if they don't state that the lab users NEED to be able to access the Application (Multicast) Servers separately. (They never made it clear whether the Application/Video Servers were multicasting the same feed or what. Which is NOT very Real World... I'm sure if you're having to make this decision, you can at least get THAT info out of the client/business. LOL) Cisco likes to promote Anycast/MSDP, though, so maybe I was wrong w/ my original logic. Remember!: Congestion AVOIDANCE = WRED Congestion MGMT = Shaping Carrier-delay: time for the system to wait to change states. (event detection, not propagation) (It's funny the things that you forget/confuse when you get test-brain-freeze.) Incomplete: Q: Layer 2 extension question A: - dark fiber (can't remember right answer) Q: Guaranteed convergence recovery for local segment 50 ms? A: - FRR/LFA (probably) (Thanks Klimero!) - BFD - SONET/SDH (can't remember if this was an option or not) Q: Network Functions Virtualization? Probably ungraded Q? - Require SDN Orchestration (chose) - Require OpenFlow Q: Make sure same path both ways (MPLS LSP Path?) This was similar to 404Q 387 (314Q 260), but the answers weren't so easy, IIRC. Q: RSVP-TE - Scalable, same merge point A: - Shared Explicit - 1:N (maybe this, 'many-to-one' or 'facility' style, scalable) - 1:1 "Note that in this approach, the MP should be the node immediately downstream to the facility." (MP = Merge Point) "When you configure TE tunnel with multiple protection on its path and merge point is the same node for more than one protection, you must configure record-route for that tunnel." [Hidden Content] [Hidden Content] [Hidden Content] [Hidden Content] Q: Source, destination based black holing, remotely triggered? A: - static Null Route (right) - BGP Next Hop change (right) - ACL Q: Burst with 20Mbps CIR and Tc of 4ms? Tc = (Bc / CIR) X 1000 4/1000 = Bc / 20000 A: Bc = 80bits = 10Bytes DHCPv6 Guard - I was torn between rate limiting (DoS) and rogue server answers. [Hidden Content] IPv6 MLD Snooping Q - Requre IGMP Snooping? - something about querier - save bandwidth? Bridge Assurance - point to point link loop prevention (hopefully they won't be mean and make a Q w/ both this and Loop Guard as options). [Hidden Content] Not sure if I should really care about this for Design track, but Cisco is Cisco. EIGRP Q on 256Kbps link (Access Rate), very unclear Q - I was torn between these 2: - police EIGRP to Access Rate (Really? wouldn't you want to go below AR? But Q sounds like it only wants you to do EIGRP) - shape all traffic (I would do this, but not sure what Cisco was asking due to the wording) I feel Cisco is not even consistent w/ how they want you to answer. Very tricky, here. RSVP-TE priority for GOLD and SILVER traffic, use different paths. - Autoroute? - Priority? VPLS - Choose BGP over LDP because: - BGP RR for route efficiency - signaling overhead I was torn between 2 answers here too. Again, very little detail in the Q, so no idea what criteria Cisco is using here! [Hidden Content] Jitter, ways to fix. - Remove load balancing, use jitter buffers (not sure if these were options). - Jitter playout buffer Carier delay (failure detection delay) vs. LSA Timers/Throttling (event propagation delay) vs. LSA Arrival timer/delay (processing delay) (OSPF?) LFA disadvantages? (I can't remember, so these answer options are just total guesses.) - can't protect in all scenarios (more of a limitation than a disadvantage really, unless there's another option available that has this advantage over LFA...) - temporary loops [Hidden Content] EIGRP, changing to OSPF, what is more important - size of domain (probably)? metrics? Security Q about GET-VPN- decrease GET-VPN SAR clock interval (affecting security) [Hidden Content] GETVPN and DMVPN together CPP - protect processor, excess traffic to CPU? SNMP? NetFlow? Recommendation for monitoring. TOGAF question The Open Group Architecture Framework - framework for enterprise architecture, provides approach for designing, planning, implementing, and governing an enterprise IT arch. BGP MED or prepending for routes incoming to AS? Placement of IPS above or below Firewall, facing Internet (not facing server) to monitor attacks from the Internet. (Wording was "firewall-facing server" or "firewall-facing internet" where dash should be a comma. "Firewall, facing the server" would have been much more clear!) Importance for SP/ISP, loops or load balancing? IPv6 SLAAC question about DNS, Q was asked somewhat differently. [Hidden Content] BGP PIC - Prefix Independent Convergence = faster backup path for convergence. [Hidden Content] [Hidden Content] HQoS Q about MLD Snooping Q about MPLS L3VPN Label Allocation? IPv6, LDP labels = per-prefix? 6PE is less scalable because is per-prefix for Labels? I think this basically answered it: "By default, Cisco NX-OS uses per-prefix label allocation which means that each prefix is assigned a label." [Hidden Content] Q about MPLS DiffServ Tunneling Modes, same QoS policy - Uniform (chose), Pipe, or Short-Pipe? Keep same QoS Value. I think this was 'short-pipe.' Pipe: "Original IP Prec/Diffserv preserved (egress queuing based on MPLS EXP)" Short-pipe "Original IP Prec/Diffserv preserved (egress queuing based in IP Prec/DiffServ)" [Hidden Content] Answer option of 'Autoroute' (might be wrong answer). Autoroute metric: specify MPLS-TE tunnel metric for IGP enhanced SPF calculation. Autoroute metric overwrites the default tunnel route metric of the shortest IGP path to the destination. [Hidden Content] HVPLS scalability Q, router or switch as CE (PE?) for mac address scalability. Router is best, so less MACs sent to PE. (Thanks to allta for reminder about this Q!) Things that tripped me up: - Multichassis routers - I second guessed myself about this answer during the test, for some reason. Maybe cuz I never worked w/ them, only VSS for switches. - DWDM - routing and wavelengths answer. (Same - never worked in much detail with the stuff.) - CWDM - passive devices require no electrical power (Same) - MPLS-TP - replaces SONET/SDH, extensions to native MPLS OAM for fault detection, monitoring, and propagation, uses an IANA assigned label 13 for OAM (didn't get this one, but I need to memorize this one in particular, since I am not familiar with MPLS-TP in RL.) - CFM - 802.1ag, not ITU-T Y.1731 (Not sure why one is right, when both include OAM CFM. Maybe they like IEEE better. I guess 802.1ag is more specific. But really, why care? I don't have to memorize this in RL. LOL) [Hidden Content] Thank you everyone that replied and helped keep us going! To the end!
