Aisha N. Feb 21, 2026 2:09 am

B and D. I thought both controllers needed matching service port IPs for HA, plus unique redundancy management IPs.

Piya K. Feb 15, 2026 7:43 am

C/D? I remember practice labs plus the Cisco doc both point to D and E as required for WLC SSO setup. You need unique redundancy IPs and the same software version, not matching licenses. Anyone see official guide list it differently?

Sanjay S. Mar 5, 2026 3:15 am

I don’t think A is required, D and E are the real must-haves here. License count can be a trap.

Ben E. Mar 1, 2026 4:05 pm

Why did you pick B instead of E? Pretty sure same OS version is a requirement for client SSO HA pairing.

Rowan R. Feb 18, 2026 3:10 pm

C/B tbh, Cisco official guide or practice test questions seem to focus more on port IPs and license count for SSO pairing.

AaronB Feb 23, 2026 6:57 am

Pretty sure A and D, because I thought license count matters for pairing in HA and unique redundancy IP is always needed. I don’t think service port IP needs to match here, but maybe I'm missing something about the OS version trap option.

Emma F. Feb 16, 2026 3:29 am

Option A

Sean J. Feb 26, 2026 5:05 pm

Its D and E, but only if you don’t mix up standby IPs. Seen reports where same OS version was missed and SSO failed.

Nora Q. Feb 13, 2026 1:39 pm

D and E tbh, saw a similar question on a practice test. Unique redundancy management IP and matching OS version are always called out for SSO. Never needed same license count for client SSO in lab setups.

Sanjay Feb 18, 2026 8:48 pm

D imo, but also E sounds right based on what I recall from the official guide and some lab scenarios.

Q: 2

During a wireless design all APs are mapped to designated controllers in case of a failure. The controllers are located in the same data center but in different racks. An AP failed over to a controller that was not defined on its High Availability tab. The customer does not want the AP to move back to its defined Cisco WLCs until they manually intervene. What needs to be addressed in the design?

Options

Discussion

Arjun T. Feb 13, 2026 10:48 am

Option B. Was it specifically asked for the AP not to revert automatically, or would auto-fallback be preferred if the original controller becomes available? That would change if A or B is correct here, since fallback setting is key.

Arjun P. Feb 22, 2026 9:46 am

Probably B

VikramG Feb 23, 2026 2:00 am

Yeah, you need B for manual AP return. Fallback enabled (A) would move them back automatically.

Grace P. Feb 22, 2026 5:36 pm

B , disabling AP fallback is what keeps the AP on the backup controller until someone manually moves it back.

HelpfulDev7207 Feb 16, 2026 1:14 am

B, not A

Jack H. Mar 4, 2026 11:18 pm

B tbh, fallback enabled (A) would force APs back to their WLC, which isn't what the customer wants.

Ravi T. Feb 26, 2026 8:04 am

B. that's what I've seen on similar practice. Official guide spells out the fallback settings for manual intervention situations.

Sara Y. Feb 26, 2026 2:49 am

Nah, I think B is correct. A is a trap since fallback enabled would auto-return the AP.

Meera Feb 22, 2026 8:47 pm

C , since changing the secondary HA unit sounds like it could control failover behavior.

Adam C. Feb 21, 2026 5:24 pm

I don’t think it’s A in this scenario. Since the customer wants to avoid automatic switchover, B is the way to go. Setting AP fallback to disabled keeps the AP on the new WLC until someone moves it manually. Pretty sure that’s how Cisco handles this, but always worth double-checking controller settings.

Q: 3

The wireless survey report shows APs staggered throughout a facility, with several of them placed on the exterior walls. Other APs are located at building corners and major turns in the structure layout. Assuming that all survey locations are optimized with a minimum of -67 RSSI at cell edges with 20% overlapping cells, for which purpose is this survey model used?

Options

Discussion

Skyler U. Mar 3, 2026 2:37 am

My pick: A - APs on exterior walls and corners lines up with location services coverage so I think this fits best. Not 100% but that's what I've seen in practice exams, open to corrections.

EmmaE Feb 27, 2026 2:01 am

Makes sense to go with A here. The corner and exterior APs are textbook for location services setups.

Nathan W. Mar 4, 2026 10:41 pm

A , because APs placed at corners and exteriors is textbook for enabling accurate location services. If it was only about coverage for voice/data/video, those corner placements would be overkill. Pretty sure that detail flips it.

Morgan M. Feb 13, 2026 8:10 am

Its A. Perimeter and corner APs are usually for location services, not just voice or data clients. D looks tempting but doesn't cover location use cases the way A does, at least from what I've seen in practice sets.

Aaron Feb 26, 2026 6:59 am

Ben A. Feb 19, 2026 8:17 am

A is wrong for just general coverage, but right for when precise location services are needed. APs on corners/exterior walls are classic signals that location tracking is in play, not just coverage for voice/data/video. Official Cisco guides and wireless design best practices mention this topology for location accuracy. If you're reviewing, I'd cross-check similar scenarios in the official guide.

Ryan E. Feb 24, 2026 9:21 am

Nah, A fits best here. D is tempting for generic coverage, but exterior and corner APs point toward location services.

Reese T. Feb 14, 2026 11:00 am

Practice test and official Cisco guide cover these scenarios, similar AP placement questions usually match A.

Alex N. Feb 24, 2026 11:32 pm

Probably A here. That overlap and staggered AP setup fits scenarios that need both location accuracy plus data and voice support.

Neha E. Feb 25, 2026 12:25 am

A tbh, since -67 RSSI and 20% overlap is typically recommended for VoIP, location, data, and video use cases.

Q: 4

An engineer must identify the network requirements for a company that has a main o®ce and 10 branch support data, voice, video, and location tracking. Which two factors must be considered? (Choose two.)

Discussion

ArjunY Feb 27, 2026 9:41 pm

B and C

Logan B. Mar 2, 2026 10:19 am

If they were asking about deployment planning instead of network requirements, wouldn't D (power sockets) actually matter more? The way it's worded feels like B and C fit better for design though.

Logan Feb 27, 2026 6:34 am

How do folks feel about C compared to D here? C seems more about coverage planning for different environments, while D feels like a physical install issue not network design. Am I missing something on deployment prep?

Emma E. Feb 22, 2026 6:59 am

Makes sense, B and C. Network requirements really come down to the number of devices and site type.

AlexQ Feb 18, 2026 6:09 am

D tbh, cause available power sockets could impact deployment, especially with lots of devices. Anyone else think it's a trap question?

Riley C. Mar 2, 2026 9:11 pm

Skip D, B and C. You need to know how many wireless clients you'll support (capacity) and what kind of sites you're designing for since warehouse vs office needs are totally different. Pretty sure those matter most here, open to other opinions.

Sanjay R. Feb 17, 2026 4:47 am

Why not B and C? D feels more like a deployment concern, not really network design. Anyone see a case for picking E here instead?

Leo F. Mar 1, 2026 9:30 am

B/C tbh, because network requirements need you to know how many devices are connecting (capacity planning) and the type of site affects coverage and design approach. D is more about install logistics than network needs directly. Not 100% but seen similar phrasing in practice.

Sam D. Mar 1, 2026 12:37 pm

B or D. Always see folks pick C but I think power sockets (D) could matter for network hardware, especially if devices need PoE. Maybe missing something obvious?

ReeseE Feb 24, 2026 2:35 pm

It’s B and C. Security policy (A) and power sockets (D) trip people up but don’t actually define network requirements for wireless design, just facility or physical access stuff. Number of wireless devices and the site type directly impact capacity and coverage planning. Pretty sure about this, feel free to disagree.

Q: 5

An enterprise network administrator is asked to set up an experimental WLAN for a collaboration project with a local service provider. The WLAN must be anchored to a WLC in the service provider data center using legacy mobility mode. After the configurations are completed on the WLCs and the firewalls in the path, the data path mobility tunnel is failing to come up. What should be performed by the administrator to debug the issue?

Options

Discussion

Logan Feb 24, 2026 6:56 am

Option B. but only if the tunnel config is confirmed and not just a port/firewall issue. Some exam reports say port testing comes up, but for actual tunnel debug, WLC mapping commands matter more.

Leo G. Feb 23, 2026 4:47 am

B. not C. Saw a similar question in some exam reports, pretty sure debugging mobility tunnels means running commands on the WLC itself. Telnet/port checks are more about connectivity, not actual debug output.

Arjun Y. Feb 28, 2026 5:32 pm

B imo

Drew Mar 4, 2026 9:05 am

B , C is a trap here since checking ports isn't a debug step like mapping on the WLC.

Kevin I. Feb 18, 2026 12:34 am

B tbh, official Cisco guides and lab practice both show WLC debug commands are the move for mobility tunnel issues.

Taylor W. Mar 5, 2026 12:32 am

C/D? Honestly not sure, kinda feels like both could fit here.

Ryan Feb 22, 2026 9:03 am

B tbh, similar question came up in some practice. Super clear what the command does here.

Quinn H. Feb 17, 2026 2:10 pm

C or D? I don't think a mapping command is the right fit for debugging a tunnel like this. Anybody else see these used?

Parker Feb 23, 2026 3:47 pm

Definitely B. Actual debug commands for mobility tunnels are run on the WLC itself, not by checking port access from a PC.

Piya Feb 13, 2026 4:02 am

Had something like this in a mock, pretty sure it's B since actual debugging for mobility tunneling issues is done using commands on the WLC. Connectivity checks like C are good for port testing, but not real debug steps. Agree?

Q: 6

A company is in the process of relocating to a new force space and ends out that the Internet circuit will not be ready before the move. The new building has a non-Cisco WLAN to which they can connect. The engineer has a 12-port switch and one Cisco autonomous AP and must connect multiple wired devices. Which additional device is needed to get all clients connected over the workgroup bridge?

Options

Discussion

Morgan Mar 4, 2026 5:16 am

My pick: A, hub won't get you L3 traffic to the WLAN so router is needed here.

Adam Feb 20, 2026 12:17 am

A here. The router handles traffic from wired devices to the Internet via the workgroup bridge, which a hub alone can't do. Hub would just get local connectivity, but not route out. Pretty sure that's what they want-unless there's some catch I'm missing.

Zoe J. Feb 13, 2026 1:21 pm

Its C. You just need a hub to connect all the wired devices to the autonomous AP acting as a workgroup bridge, right? Don't see why you'd need routing here if it's just about local connectivity for now. Maybe I'm missing something, but pretty sure hub should be enough in this setup.

Rowan U. Mar 2, 2026 12:45 pm

Router (A) is needed since the workgroup bridge only connects wired clients to the WLAN, but to actually enable Internet access you have to have routing. Switch or hub alone wouldn't handle this aspect. Pretty sure that's what it's asking for.

Ivy S. Mar 3, 2026 5:06 am

Probably A, need the router for routing through the workgroup bridge, hub's just a distractor here.

SkepticalLearner8252 Mar 5, 2026 10:02 am

Option C, since hub is usually what folks pick for just connecting wired devices, though maybe that's the trick here.

Robin U. Feb 27, 2026 1:47 pm

A tbh, but only if they truly need Internet before the circuit is live. Otherwise, hub would cover pure LAN bridging.

Sean F. Feb 17, 2026 11:04 am

A saw a similar scenario in official practice. Router required to provide the L3 path for wired clients through the AP.

Sofia U. Feb 16, 2026 11:51 pm

Option A router

Nora K. Feb 16, 2026 10:08 am

C isn’t enough since you want those wired devices to reach the Internet, not just talk locally. A router (A) is needed for actual layer 3 routing between the switch/clients and the WLAN via the bridge. Pretty sure about this, unless I missed a detail.

Q: 7

A customer has a single anchor WLC named Anchor A. Anchor A is in a DMZ and provides guest access. The customer wants to deploy an additional anchor controller named Anchor B to provide redundancy if Anchor A fails. Which design approach should be taken for the guest WLAN priority on the foreign WLC for each anchor WLC?

Options

Discussion

Layla K. Feb 13, 2026 7:54 pm

D , lower number = higher priority so set Anchor A to 1 and Anchor B to 3.

Logan K. Feb 22, 2026 1:10 am

D is the way I'd set it up for pure redundancy. Lower number is higher priority, so Anchor A gets 1 (primary) and Anchor B gets 3 (secondary). That's straight from Cisco docs on anchor WLC failover, pretty sure that's how most people do it.

JasonH Feb 26, 2026 9:01 am

D for redundancy setup. Lower number means higher priority, so primary Anchor A should be 1, backup Anchor B as 3. I think that's what Cisco recommends for failover rather than load balancing. Disagree?

Sean K. Feb 21, 2026 7:31 am

Tricky, since a lot of configs get tripped up by anchor priorities. D

Owen Feb 27, 2026 3:13 pm

Seriously Cisco, why is anchor controller priority so backwards? Picking D here because lower number means primary (Anchor A at 1), Anchor B at 3 for backup. That matches redundant guest design docs, but let me know if I missed a twist.

Taylor Feb 20, 2026 9:36 am

Option D

Jordan E. Mar 3, 2026 4:52 am

C or D
Not totally sure because both options have valid use cases, but since it's for redundancy only (not load balancing), maybe D fits better here. Anyone else think otherwise?

Ravi R. Feb 21, 2026 5:36 pm

C is tempting if you want both anchors active but for pure failover, D is correct. The moment you need load balancing, that's when C makes sense instead.

Arjun Feb 21, 2026 8:31 pm

Its D for redundancy since priority 1 is primary and 3 is backup, pretty sure that's the Cisco way.

Ishaan U. Feb 20, 2026 1:33 am

Nah, it's D. C looks tempting but that's how you'd set it for load balancing, not pure redundancy like the question asks.

Q: 8

Two cisco 5520 wireless LAN controllers are managing all access points throughout the network. The WLCs are in different locations to provide geographical redundancy a mobility group has been configured on both WLCs and has a UP status on both controllers. The Aps in location A are statically configured to use controller A as the primary and controller B as the secondary. If the WLC in location A goes offline. The Aps successfully join the WLC in location, but they do not fail over to their primary configured controller. Which configuration task fixes the issue?

Options

Discussion

Mia V. Feb 23, 2026 2:05 pm

D imo , since changing the AP Failover Priority to critical seems like it should force the APs to return to their primary faster. The auto-fallback part feels like a trap in C but open to another take.

Cameron S. Feb 13, 2026 10:47 pm

Option C fixes it because without global AP fallback enabled, APs won't move back to their primary controller once it's online again. I remember a similar edge case in a practice test where fallback had to be explicitly turned on. Correct me if someone knows a firmware that flips this.

MiaR Feb 21, 2026 8:21 am

Seen this in some practice labs, enabling AP fallback globally on the WLC (so C) is necessary for APs to automatically return to their primary controller after a failover. Just setting priorities or using DHCP options won’t trigger the fallback. If you’re prepping, official Cisco guides and lab practice really help clarify these controller behaviors. Pretty sure about C but let me know if someone has had different results.

Nina J. Feb 28, 2026 8:01 pm

Its D, but if fallback isn't needed automatically this option still controls which controller gets picked first after outage.

Robin V. Feb 24, 2026 1:19 pm

C . D looks tempting but that's only for failover priority, not for automatic fallback. Seen similar question on practice sets where enabling AP fallback globally lets APs rejoin their primary controller when it's back online.

Riley Feb 26, 2026 8:54 pm

Probably C since global AP fallback needs to be enabled for the access points to move back to their primary WLC automatically. Without it, they'll stay on the secondary after failover even if the primary comes online. Correct me if I'm missing an edge case.

Skyler B. Feb 17, 2026 7:15 pm

I don't think D really solves the fallback issue here. Setting AP failover priority changes how APs pick a controller during a failover, but it doesn't make them return to their primary when it comes back up. That feature is controlled by enabling AP fallback globally (C). Seen similar question in practice materials, so I'm pretty sure that's what Cisco wants. Anyone get different results on real gear?

PiyaL Feb 18, 2026 2:45 pm

I don't think changing the AP Failover Priority to critical (D) is what you want here. That mainly affects the order for initial failover, not fallback to primary. You have to enable AP fallback globally (C) so that APs will auto-return to their preferred controller when it comes back up. Seen similar behavior in Cisco labs. Let me know if anyone's seen different.

Adam F. Feb 26, 2026 11:51 pm

C , because without AP fallback enabled globally, the APs won't return to their primary even after it comes back online. There's that little gotcha where static controller assignment alone isn't enough. If someone has seen different behavior based on code version, chime in.

SeasonedArchitect8628 Feb 19, 2026 1:36 pm

C/D? D seems tempting since failover priority sounds like it should force fallback, but I think it's a common trap.

Q: 9

A customer has a central Cisco WLC that manages APs in FlexConnect mode. The wireless infrastructure supports multiple small branches. One branch deploys new CCX wireless phones that are authenticated by a central Cisco ISE via PEAP/IMSCHAPv2, and tra®c is switched locally. The customer must reduce the number of full authentication requests and optimize roaming for the new phones. Which action accomplishes the requirement?

Options

Discussion

CarefulAuditor710 Feb 13, 2026 8:26 am

A . FlexConnect group with CCKM lets you optimize fast roaming and keeps auth requests down, which is what the question wants.

Ben Mar 2, 2026 12:39 pm

Option D is tempting but only FlexConnect groups let APs share keys for local switching, so A.

Sean X. Mar 2, 2026 11:54 pm

Nah, I think it's A here since D is the trap for central switching.

Ben Z. Feb 17, 2026 9:45 am

Geez, Cisco makes this unnecessarily confusing with FlexConnect and all these groupings. But A is what you want for fast roaming with local switching.

Emma J. Feb 18, 2026 8:08 am

C or D? These FlexConnect and CCKM questions drive me nuts. Cisco's docs always make it a guessing game.

Ajay I. Mar 5, 2026 11:56 am

D is wrong, A fits since FlexConnect group and CCKM are key for fast roaming with local switching.

Riley S. Feb 27, 2026 7:37 am

I think it's A since FlexConnect group is needed for local switching and CCKM handles the fast roaming piece. Saw similar question in practice and this combo was flagged as right. Open to other takes if I missed something though.

Luna L. Feb 22, 2026 11:46 pm

For me, A. FlexConnect group plus CCKM matches up with local switching and minimizing full auths for roaming, fits the question.

Sofia Q. Feb 15, 2026 10:38 am

C/D? I keep seeing people pick A but something still makes me wonder if D works too in some setups.

Ava S. Mar 1, 2026 2:15 am

A , not D. The local switching piece plus CCKM and FlexConnect group is the combo for fast roaming and fewer full auths. D looks tempting but that's more for central switching scenarios. If someone disagrees let me know, but pretty sure A fits best here.

Q: 10

Clustering Cisco WLCs into a single RF group enables the RRM algorithms to scale beyond the capabilities of a single Cisco WLC. How many WLC and APs in an RF group can the controller software scale up to in WLC release 8.9 depending on the platform?

Options

Discussion

Reese Mar 1, 2026 4:17 am

Option D for sure, since with WLC release 8.9 and the right hardware, you can cluster up to 20 WLCs and 6000 APs in a single RF group. Cisco upped the max APs per RF group at this version, so older numbers like 4000 (C) are outdated. Not totally sure for every platform, but pretty confident for top models. Someone catch anything else?

AjayW Feb 26, 2026 1:18 pm

D . The Cisco config guide for WLC 8.9 says 6000 APs, and official docs plus practice questions back that up. Would double check the official guide if you're reviewing limits like this.

QuietLead7682 Feb 26, 2026 1:24 pm

C vs D? Had something like this in a mock, picked D for 6000 APs.

Hannah D. Feb 17, 2026 12:43 pm

C vs D? Trick wording but with release 8.9, max supported is 6000 APs so D not C.

Karan B. Feb 24, 2026 9:55 pm

D , older docs show 4000 APs which traps some folks but 6000 is right with 8.9 as per Cisco docs.

Maya P. Mar 1, 2026 6:08 pm

Had something like this in a mock and I picked C. Pretty sure some guides still list 4000 APs per RF group, maybe for certain hardware or earlier docs. Not 100% though since Cisco updated limits, so open to being wrong here.

QuietArchitect9995 Feb 23, 2026 12:31 pm

Sanjay K. Feb 14, 2026 9:39 pm

Pretty sure the limit is 20 WLCs and 6000 APs per RF group for release 8.9. Cisco docs mention that max support in newer versions too. D is correct based on what I saw in recent exam reports.

Cameron Mar 3, 2026 12:23 pm

Likely D is the max supported, but older revisions made me hesitate. Anyone confident it's not C for all platforms?

Luke Feb 19, 2026 12:59 pm

Does anyone think C is right here? Looks like D could be the common trap, since earlier releases topped out at 4000 APs.
