• Question 1185:

  In an SD-Access solution what is the role of a fabric edge node?

  A. to connect external Layer 3- network to the SD-Access fabric

  B. to connect wired endpoint to the SD-Access fabric

  C. to advertise fabric IP address space to external network

  D. to connect the fusion router to the SD-Access fabric

  Correct Answer: B

  + Fabric edge node: This fabric device (for example, access or distribution layer device) connects wired endpoints to the SDA fabric.

  

• Question 1186:

  Refer to the exhibit.

  

  

  An engineer is investigating why guest users are able to access other guest user devices when the users are connected to the customer guest WLAN. What action resolves this issue?

  A. implement MFP client protection

  B. implement split tunneling

  C. implement P2P blocking

  D. implement Wi-Fi direct policy

  Correct Answer: C

  Reference: 2.3 Ensure `Peer-to-Peer Blocking Action` is set to `Drop' for All `Wireless LAN Identifiers' (Scored)

  Description:

  This control determines whether the Wireless LAN Controller is configured to prevent clients connected to the same Wireless Local Area Controller from communicating with each other. Wireless Client Isolation prevents wireless clients from

  communicating with each other over the RF. Packets that arrive on the wireless interface are forwarded only out the wired interface of an Access Point. One wireless client could potentially compromise another client sharing the same wireless

  network.

• Question 1187:

  Correct Answer: ACF

• Question 1188:

• Question 1189:

  Refer to the exhibit. Which command must be applied to R2 for an OSPF neighborship to form?

  

  A. network 20.1.1.2.0.0.0.0 area 0

  B. network 20.1.1.2 255.255.0.0. area 0

  C. network 20.1.1.2.0.0.255.255 area 0

  D. network 20.1.1.2 255.255.255 area 0

  Correct Answer: A

  The network 20.0.0.0 0.0.0.255 area 0 command on R2 did not cover the IP address of Fa1/1 interface of R2 so OSPF did not run on this interface. Therefore we have to use the command network 20.1.1.2 0.0.255.255 area 0 to turn on OSPF on this interface. Note: The command network 20.1.1.2 0.0.255.255 area 0 can be used too so this answer is also correct but answer C is the best answer here. The network 0.0.0.0 255.255.255.255 area 0 command on R1 will run OSPF on all active

• Question 1190:

  An engineer is troubleshooting the Ap join process using DNS. Which FQDN must be resolvable on the network for the access points to successfully register to the WLC?

  A. wlcbostname.domain.com

  B. cisco-capwap-controller.domain.com

  C. ap-manager.domain.com

  D. primary-wlc.domain.com

  Correct Answer: B

  DNS: If you have configured your DHCP server to provide both option 006 (DNS server address) and option 015 (domain name) information, the AP can obtain WLC addresses from the DNS server. The process works as follows:

  1.

  The AP gets its IP address from DHCP with options 6 and 15 configured.

  2.

  The AP can obtain the IP address of the DNS server from the DHCP option.

  3.

  The AP uses this information to perform a hostname lookup using CISCO-CAPWAP-CONTROLLER., which resolves to available WLC management interface IP addresses (IPv4 or IPv6, or both).

  4.

  The AP can then perform a directed message to associate to responsive WLCs.

  To prevent all APs from joining a single controller based on a DNS name resolution, the domain name may vary; this is what is done to dispatch APs to different controllers across the enterprise network, based on different domain names that are configured in their respective DNS scopes.
