Yes. TorrentValid provides a free PDF demo of the 400-351 practice questions, so you can check the format and quality before paying anything. Every purchase also includes 365 days of free updates, and once that period expires you can extend the update service at a 50% discount from your member zone.

The 400-351 exam gives you 120 minutes to work through 90-110 questions, so the clock moves faster than most candidates expect. Keep a steady pace on every item, flag the ones that stall you, and circle back with the time you have banked instead of getting stuck. Time pressure is mostly a rehearsal problem: run at least one full timed mock in the TorrentValid test engine before your appointment, and the real countdown will feel familiar rather than threatening.

The 400-351 exam — officially titled CCIE Wireless Written — is the Cisco test you pass to earn the CCIE Wireless certification. It sits at the Expert level of the Cisco certification program. Related certifications include Cisco Certified Specialist - Wireless Core. If that is the credential you are after, the 520 practice questions at TorrentValid map directly to its official objectives.

The Cisco CCIE Wireless Written blueprint is organized into 6 domains. The first three are:

  • WLAN Design and Implementation (20%)
  • Evolving Technologies (10%)
  • WLAN Operation and Troubleshooting (15%)

The complete, current topic list appears in the exam outline section above — review it before you start drilling the TorrentValid practice questions.

If you take the corresponding 400-351 exam within 60 days of purchase and do not pass, you can apply for a full refund under our money-back guarantee. Send a scanned copy of your exam enrollment slip together with the official Score Report PDF within 2 days of your exam date, and your claim will be processed within 7 days. Keep in mind that the candidate name must match the purchaser name, and the guarantee does not cover attempts made within 3 days of purchase, materials that were downloaded but never used in an actual exam sitting, free resources, or expired orders. If you would rather keep studying, you can swap the refund for two free exam products of equal value while keeping the update service on your original purchase. Delivery itself is instant: the files are emailed to you within one minute of payment (if nothing arrives within 2 hours, check your spam folder and contact our support team), and there is no limit on how many computers you install them on.

Depending on your location, you can take the 400-351 exam In-person at authorized Pearson VUE test centers or online proctored exam.

The passing score for the 400-351 exam is Not publicly disclosed (Pass/Fail result), and the official registration fee is USD $450. Remember that an unsuccessful attempt means paying the full USD $450 again to retake it, so booking too early is the expensive way to find out you are not ready. Test yourself with the TorrentValid practice questions first; once you can clear Not publicly disclosed (Pass/Fail result) comfortably on timed runs, scheduling the real exam becomes a much safer bet.

Cisco points 400-351 candidates to the following official training options:

Whichever course you pick, round it out with the 520 practice questions at TorrentValid — courseware builds the theory, and timed practice turns it into exam-day speed.

Cisco CCIE Wireless Written Sample Questions:

Question #1

Your WLC is running code 8.7 and you have deployed COS APs on your network. Which two
802.1X authentication methods are supported when the AP acts as a supplicant? (Choose two.)

  • A. LEAP
  • B. EAP-FAST
  • C. EAP-MD5
  • D. EAP-PSK
  • E. EAP-TLS
Reveal Solution  Discussion  0

Correct Answer: B,E  🗳️

Question #2

Assuming that the antenna system characteristics (for example, gain VSWR, polarization and beam width) are similar for a 5-GHz and 2.4-GHz radio. While conducting a dual band site survey, how to configure the 5-GHz radio, relative to the 2.4-GHz radio, in order to achieve similar cell size?

  • A. The 5-GHz radio should use BPSK modulation and the 2.4 GHz radio should use CCK modulation
  • B. The 5-GHz radio power level should be lower than the 2.4-GHz radio
  • C. The 5-GHz radio should use CCK modulation and the 2.4-GHz radio should use BPSK modulation
  • D. The 5-GHz radio power level should be higher than the 2.4-GHz radio

Correct Answer: D  🗳️

Question #3

You are designing a wireless network for a museum. One of their requirements is to track people inside the museum and push a notification into their tablet device as soon as they step in front of a painting with information about the artist and the painting. This information must be delivered in real time. You are using regular probe request-based tracking and during testing.
You notice that although the tablet Is connected to the museum Wi-Fi network, the location is not updating in real time as you move. It can take almost 2 minutes for the location to be updated.
Which option is the likely reason for this issue?

  • A. Probe request-based tracking is device dependent. The tablet might not send a probe request if it is maintaining a good Wi-Fi signal, which can cause slower location updates.
  • B. Probe request-based tracking is bound to delay due to the broadcast type of traffic that is not acknowledged over the air and could be lost.
  • C. CCXv4 S60 is disabled by default. You must enable CCXv4 S60, which is compatible with all Wi- Fi clients. This feature comes out location updates more frequently.
  • D. Cisco MSE does not perform a new location calculation for certain elements if the resulting position is not at least 5 meters different than the previous location.

Question #4

Which statement about wireless LAN security in a Cisco Unified Wireless Network VoWLAN deployment is false?

  • A. Although LEAP is considered secure for VoWLAN handsets when correctly deployed, it is recommended that a different EAP method (FAST, PEAP, TLS) is used, if available.
  • B. When using WPA Personal, strong keys should be used to avoid a dictionary attack.
  • C. When using EAP authentication, the EAP-Request timeout value should be adjusted based only on the advice of the VoWLAN handset vendor.
  • D. Dynamic WEP mitigates the security weaknesses in static WEP, making it a viable option that can be relied upon to secure a VoWLAN deployment.
  • E. EAP-FAST, if available, is the recommended EAP type for use in VoWLAN deployments.

Correct Answer: C  🗳️

Question #5

For the following cipher suites, which were defined in the IEEE 802.11i-2004 standard and then again in the 802.11-2007 standard? Select all that apply.

  • B. WEP-104
  • C. TCP-IP
  • D. AES-CCMP
  • E. WEP-40
