Cisco 350-401 Online Questions & Answers

• Question 1471:

  A customer has several small braches and wants to deploy a WI-FI solution with local management using CAPWAP.

  Which deployment model meets this requirement?

  A. Autonomous
  B. Mobility express
  C. SD-Access wireless
  D. Local mode
  B. Mobility express

  ---

  Explanation

  Correct answer is Mobility Express. From Encor Cert guide: "As you might have guessed, it is also possible to move the WLC even below the access layer and into an AP. Figure 18-7 illustrates the Mobility Express topology, where a fully functional Cisco AP also runs software that acts as a WLC. This can be useful in small scale environments,such as small, midsize, or multi-site branch locations, where you might not want to invest in dedicated WLCs at all. The AP that hosts the WLC forms a CAPWAP tunnel with the WLC, as do any other APs at the same location. A Mobility Express WLC can support up to 100 APs."

• Question 1473:

  Refer to the exhibit.

  

  An engineer attempts to configure a trunk between switch SW1 and switch SW2 using DTP, but the trunk does not form.

  Which command should the engineer apply to switch SW2 to resolve this issue?

  A. switchport mode dynamic desirable
  B. switchport mode access
  C. no switchport
  D. switchport nonegotiate
  A. switchport mode dynamic desirable

  Explanation

  DESIRABLE must be paired with AUTO on other side to form.

• Question 1474:

  Which action is a function of VTEP in VXLAN?

  A. tunneling traffic from IPv6 to IPv4 VXLANs
  B. allowing encrypted communication on the local VXLAN Ethernet segment
  C. encapsulating and de-encapsulating VXLAN Ethernet frames
  D. tunneling traffic from IPv4 to IPv6 VXLANs
  C. encapsulating and de-encapsulating VXLAN Ethernet frames

  ---

  Explanation

  VTEPs connect between Overlay and Underlay network and they are responsible for encapsulating frame into VXLAN packets to send across IP network (Underlay) then decapsulating when the packets leaves the VXLAN tunnel.

  

• Question 1475:

  DRAG DROP

  Drag and drop the virtual components from the left onto their descriptions on the right.

  Select and Place:

  

  

  ---

  + configuration file containing settings for a virtual machine such as guest OS: VMX

  + component of a virtual machine responsible for sending packets to the hypervisor: vNIC

  + zip file containing a virtual machine configuration file and a virtual disk: OVA

  + file containing a virtual machine disk drive: VMDK

  The VMX file simply holds the virtual machine configuration.

  VMDK (short for Virtual Machine Disk) is a file format that describes containers for virtual hard disk drives to be used in virtual machines like VMware Workstation or VirtualBox.

  An OVA file is an Open Virtualization Appliance that contains a compressed, "installable" version of a virtual machine. When you open an OVA file it extracts the VM and imports it into whatever virtualization software you have installed on your computer.

• Question 1476:

  Which wireless deployment mode uses a Flex architecture and allows Layer 2 roaming between APs without a physical wireless controller?

  A. Unified
  B. autonomous mode
  C. fabric
  D. Cisco Mobility Express
  D. Cisco Mobility Express

• Question 1477:

  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
  B. cisco-capwap-controller.domain.com

  ---

  Explanation

  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.<localdomain>, 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.

• Question 1478:

  When is an external antenna used inside a building?

  A. only when using Mobility Express
  B. when it provides the required coverage
  C. only when using 2 4 GHz
  D. only when using 5 GHz
  B. when it provides the required coverage

• Question 1479:

  What are two differences between the RIB and the FIB? (Choose two.)

  A. The FIB is derived from the data plane, and the RIB is derived from the FIB.
  B. The RIB is a database of routing prefixes, and the FIB is the Information used to choose the egress interface for each packet.
  C. FIB is a database of routing prefixes, and the RIB is the information used to choose the egress interface for each packet.
  D. The FIB is derived from the control plane, and the RIB is derived from the FIB.
  E. The RIB is derived from the control plane, and the FIB is derived from the RIB.
  B. The RIB is a database of routing prefixes, and the FIB is the Information used to choose the egress interface for each packet.
  E. The RIB is derived from the control plane, and the FIB is derived from the RIB.

  Explanation

  The Forwarding Information Base (FIB) contains destination reachability information as well as next hop information. This information is then used by the router to make forwarding decisions. The FIB allows for very efficient and easy lookups.

• Question 1480:

  When a DNS host record is configured for a new Cisco AireOS WLC, which hostname must be added to allow APs to successfully discover the WLC?

  A. CONTROLLER-CAPWAP-CISCO
  B. CISCO-CONTROLLER-CAPWAP
  C. CAPWAP-CISCO-CONTROLLER
  D. CISCO-CAPWAP-CONTROLLER
  D. CISCO-CAPWAP-CONTROLLER
