2. Question 692 · 1003 in bank

   Which statement about VXLAN is true?

   • AVXLAN encapsulates a Layer 2 frame in an IP-UDP header, which allows Layer 2 adjacency across router boundaries.
   • BVXLAN uses the Spanning Tree Protocol for loop prevention.
   • CVXLAN extends the Layer 2 Segment ID field to 24-bits, which allows up to 4094 unique Layer 2 segments over the same network.
   • DVXLAN uses TCP as the transport protocol over the physical data center network.

   Show answer

   Answer: A

   Explanation

   https://tools.ietf.org/html/rfc7348 Due to this encapsulation, VXLAN could also be called a tunneling scheme to overlay Layer 2 networks on top of Layer 3 networks

3. Question 693 · 1003 in bank

   Which statement describes the Cisco SD-Access plane functionality for fabric-enabled wireless?

   • AThe control plane traffic is sent to the WLC through VXLAN, and the data plane traffic is sent to the WLC through CAPWAP tunnels.
   • BControl plane traffic and data plane traffic are sent to the WLC through CAPWAP tunnels.
   • CThe control plane traffic is sent to the WLC through CAPWAP tunnels, and the data plane traffic is sent from the AP to the fabric edge switch through VXLAN.
   • DControl plane traffic and data plane traffic are sent to the WLC through VXLAN.

   Show answer

   Answer: C

   Explanation

   "In SD-Access Wireless, the control plane is centralized. This means that, as with Cisco Unified Wireless Network, a Control and Provisioning of Wireless Access Points (CAPWAP) tunnel is maintained between APs and WLC. The main difference is that in SDAccess Wireless, the data plane is distributed using a Virtual Extensible LAN (VXLAN) directly from the fabric-enabled APs." https://www.cisco.com/c/dam/en/us/td/docs/cloud-systems-management/network-automation-and-management/dna-center/deploy-guide/cisco-dna-center-sd-access-wl-dg.pdf

4. Question 694 · 1003 in bank

   A company hires a network architect to design a new OTT wireless solution within a Cisco SD-Access Fabric wired network. The architect wants to register access points to the WLC to centrally switch the traffic. Which AP mode must the design include?

   • Alocal
   • Bbridge
   • CFlexConnect
   • Dfabric

   Show answer

   Answer: A

   Explanation

   Designing the wireless integration in SD-Access: As mentioned earlier, there are two possible designs for deploying wireless with an SD-Access fabric: • Cisco Unified Wireless Network wireless OTT: The SD-Access fabric is just an IP transport network, and wireless is a pure overlay. • SD-Access Wireless: Wireless is integrated into SD-Access and can leverage all the advantages of the fabric. -------- Let's recap some of the important design considerations for OTT mode: At FCS, the only mode supported as OTT is Centralized (AP local mode) --------

5. Question 695 · 1003 in bank

   Select 2

   Which two methods are used to interconnect two Cisco SD-Access Fabric sites? (Choose two.)

   • ASD-Access transit
   • Bfabric interconnect
   • Cwireless transit
   • DIP-based transit
   • ESAN transit

   Show answer

   Answer: AD

   Explanation

   IP transit: Uses a regular IP network to connect to an external network or to connect two or more fabric sites. It leverages a traditional IP-based (VRF-LITE, MPLS) network, which requires remapping of VRFs and SGTs between sites. SD-Access transit: Uses LISP/VxLAN encapsulation to connect two fabric sites. The SD-Access transit area may be defined as a portion of the fabric that has its own control plane nodes, but does not have edge or border nodes. However, it can work with a fabric that has an external border. With an SD-Access transit, an end-to-end policy plane is maintained using SGT group tags.

10. Question 700 · 1003 in bank

    How do cloud deployments compare to on-premises deployments?

    • ACloud deployments provide a better user experience across world regions, whereas on-premises deployments depend upon region-specific conditions.
    • BCloud deployments mandate a secure architecture, whereas on-premises deployments are inherently unsecure.
    • CCloud deployments must include automation infrastructure, whereas on-premises deployments often lack the ability for automation.
    • DCloud deployments are inherently unsecure, whereas a secure architecture is mandatory for on-premises deployments.

    Show answer

    Answer: A

    Explanation

    I think A sounds bettter Easily deploy your application in multiple regions around the world with just a few clicks. This means you can provide lower latency and a better experience for your customers at minimal cost. https://docs.aws.amazon.com/whitepapers/latest/aws-overview/six-advantages-of-cloud-computing.html
