Cisco CCNP Enterprise 300-425 Questions & Answers

• Question 151:

  A medium-sized hospitality company with 50 hotels needs to upgrade the existing WLAN in each hotel to 802.11n. During the site surveys for each hotel, what needs to be taken into consideration when determining the locations for each AP?

  A. Selecting locations that are easily accessed so maintenance and upgrades can be performed quickly.

  B. Selecting AP locations where power is already available.

  C. Selecting APs that can be hidden in ceiling panels to provide a secure and clean aesthetic look.

  D. Selecting locations that make visual assessment of the AP operation easy.

  Correct Answer: C

• Question 152:

  How are mobility groups created, excluding mobility anchors?

  A. The WLCs do not have to be of the same model or type to be a member of a mobility group; however, each member should be running different software versions.

  B. A mobility group does not require all WLCs in the group to use the same virtual IP address.

  C. Each WLC must use the same mobility domain name and be defined as a peer in each other's static mobility members list.

  D. If WLCs with HA SSO are deployed, each WLC in the WLC HA pair is considered separately as a mobility peer.

  Correct Answer: D

• Question 153:

  How should the concept of mobility domains and mobility groups be explained to a customer?

  A. WLCs do not need to be in the same mobility domain to communicate with each other Mobility groups constrain the distribution of security context of a client and also constrain AP fail-over between controllers.

  B. A mobility group does not constrain the distribution of security context of a client and also does not constrain AP fail-over between controllers when the WLCs are in the same mobility domain.

  C. if WLCs are in same mobility domain, they communicate with each other. Mobility groups constrain the distribution of security context of a client and also constrain AP fail-over between controllers.

  D. If WLCs are in the same mobility domain, they communicate with each other but. if an anchor WLC ?present, it must: be in the same mobility domain for communication to be possible.

  Correct Answer: C

• Question 154:

  A customer is looking for a network design with Cisco Hyperloctation using AP4800 for location tracking via a custom mobile app Issues appeared in the past with refresh rates for location updates. What needs to be implemented to meet these requirements?

  A. Cisco CMX SDK in the location app

  B. redundant CMX and fetch location in round-robin fashion.

  C. device Bluetooth via the app

  D. Cisco FastLocate technology

  Correct Answer: D

  C. Wireshark

  D. Cisco spectrum expert

  Correct Answer: D

• Question 158:

  An engineer must perform an assessment of a customer LAN for a future IEEE 802.11ac Wave 2 wireless deployment All access switches are Fast Ethernet-Capable only, and the wired infrastructure between existing APs and access switches is based on the CAT 6A standard. Which two actions provide maximum support of Cisco 3800 Series access points? (Choose two.)

  A. Replace the existing switches with mGig switches.

  B. Replace the existing switches with gigabit switches with 10G uplinks.
