  1. Question 1 of 5Wireless Network Operation

    Catalyst APs running an AP image from IOS XE 17.9 discover a Catalyst 9800 running 17.12. What happens during the join?

    1. The controller rejects the join until you upgrade the APs from a TFTP server
    2. The APs join and keep running the 17.9 image until the next AP reboot
    3. The controller downgrades its own AP image bundle to match the 17.9 APs
    4. The APs download the matching image from the controller, reboot, then join
    Show the answer

    Answer: D. The APs download the matching image from the controller, reboot, then join. After the DTLS session and join request, an AP whose image differs from the controller enters the image data state, downloads the image over CAPWAP, reboots and joins again with the matching version. The AP image always follows the controller. A version mismatch at join triggers an image download over CAPWAP and a reboot, which is why a controller upgrade or a migration between controllers on different releases makes APs reload. Predownload reduces the outage during planned upgrades.

  2. Question 2 of 5RF Fundamentals

    In a warehouse full of steel racks, older single-antenna 802.11a scanners show many CRC errors and retries even where they report -60 dBm. In the same aisles, 2x2 802.11ac laptops work well. Which explanation fits best?

    1. Free space path loss along the long aisles drops the signal below the scanners' receive sensitivity
    2. The steel racks absorb most of the 5 GHz energy, so the scanners get less signal than they report
    3. Refraction through the steel racks bends the signal away from the scanners and lowers its level
    4. Reflections from the racks create multipath, and single-antenna radios cannot combine the copies
    Show the answer

    Answer: D. Reflections from the racks create multipath, and single-antenna radios cannot combine the copies. Metal reflects RF, so delayed copies of each frame arrive by many paths and can cancel at a single antenna. Multi-chain radios use MRC and MIMO to turn the extra paths into gain. Reflection off metal is the main source of multipath indoors. Multipath can cause fading and corrupted frames even at good RSSI on single-antenna radios, while 802.11n/ac/ax radios with several chains use MRC, beamforming and spatial multiplexing to benefit from it.

  3. Question 3 of 5Client Connectivity Configuration

    The Catalyst 9800 client list shows these four MAC addresses. Which one is a locally administered address, the kind that a phone or laptop generates when it uses MAC randomization?

    1. f4f5.e812.0a9c
    2. 3c22.fb10.7a01
    3. 9a4b.2c71.d0e6
    4. a4c3.f055.1b20
    Show the answer

    Answer: C. 9a4b.2c71.d0e6. 0x9a = 1001 1010: bit 1 of the first octet (the U/L bit) is 1, so the address is locally administered. Any MAC whose second hex digit is 2, 6, A or E has this bit set. Randomized MACs set the locally administered bit (bit 1 of the first octet) and clear the multicast bit, so their second hex digit is 2, 6, A or E. Such an address has no vendor OUI, which is why OUI-based profiling and MAC lists built from burned-in addresses stop matching.

  4. Question 4 of 5Wireless Monitoring and Management

    An engineer restores last month's Catalyst 9800 configuration with copy tftp: running-config. Afterwards, a WLAN that was created after the backup still exists, even though it is not in the backup file. Why, and how should the backup be restored?

    1. WLANs sit in a separate wireless database that a config copy never touches, so they must be deleted by hand
    2. The running config was locked by an open GUI session; close that session and run the same copy again
    3. The backup came from an older release, so the parser skipped every line that defines a WLAN profile
    4. A copy to running-config merges lines; copy the file to startup-config and reload to get the exact backup
    Show the answer

    Answer: D. A copy to running-config merges lines; copy the file to startup-config and reload to get the exact backup. Copying a file into running-config only adds and changes lines; it never removes what the file does not mention. Writing it to startup-config and reloading replaces the whole configuration. On IOS XE, including the Catalyst 9800, copy <file> running-config is a merge: lines in the file are applied, lines missing from it stay. To return exactly to a backup, copy it to startup-config and reload, ideally in a maintenance window and with a fresh backup of the current state first.

  5. Question 5 of 5802.11 Technology Fundamentals

    A new laptop reports support for 4096-QAM and 320 MHz channels. Which amendment does it implement, and where can it use a 320 MHz channel?

    1. 802.11ax; the 320 MHz channel exists in both 5 GHz and 6 GHz
    2. 802.11be; the 320 MHz channel exists only in the 6 GHz band
    3. 802.11be; 320 MHz can be built in 5 GHz by bonding UNII-1 to UNII-3
    4. 802.11ac Wave 2; the 320 MHz channel exists only in the 6 GHz band
    Show the answer

    Answer: B. 802.11be; the 320 MHz channel exists only in the 6 GHz band. 4096-QAM and 320 MHz channels arrived with 802.11be (Wi-Fi 7). The 5 GHz band has no 320 MHz of contiguous spectrum, so 320 MHz channels are defined only in 6 GHz. Know the headline features by amendment: 802.11n (MIMO, 40 MHz, 64-QAM), 802.11ac (5 GHz only, 160 MHz, 256-QAM, DL MU-MIMO), 802.11ax (OFDMA, 1024-QAM, 6 GHz with Wi-Fi 6E), 802.11be (MLO, 4096-QAM, 320 MHz in 6 GHz only).

Exam domains covered

Weights follow Cisco’s published exam topics for WLCOR 350-101 v1.0. Wireless left ENCOR in March 2026 and now has its own CCNP track built on this exam.

Why every option is explained

I failed my first CCNA attempt with 58%. I had memorised answers without understanding why the other options were wrong, and the exam found every gap. CertAce is the tool I wished I had then: for each question you see why the right answer is right and why each wrong one is wrong.

Questions people ask

How long is the WLCOR 350-101 exam?

120 minutes. Cisco does not publish a fixed number of questions; candidates usually report around 90 to 110. WLCOR v1.0 has seven domains, from RF fundamentals to automation and AI. It is the core exam of the CCNP Wireless track that Cisco launched in March 2026, and the qualifying exam for the CCIE Wireless lab.

Is wireless still on ENCOR?

No. ENCOR 350-401 v1.2 removed RF, AP modes, controllers, roaming and wireless security, and Cisco moved that material into WLCOR. If you want a wireless CCNP, you now take WLCOR plus a wireless concentration exam (design or implementation), not ENCOR.

What score do I need to pass WLCOR?

Cisco does not publish the passing score, and the score report is scaled. Book the exam when you pass several full timed quizzes here comfortably, in every domain.

Which WLCOR domains are hardest?

Wireless Network Operation and Client Connectivity Configuration are 20% each and most of it is Catalyst 9800 configuration: profiles and tags, AP join, 802.1X with ISE, roaming and guest anchors. RF math looks easy until you have to do it fast without a calculator.

Is CertAce free?
