(Choose two.)

   • AIP directed broadcast and forward-protocol must be enabled on all the SVI or routed interfaces where the client subnets reside
   • BIP directed broadcast and forward-protocol must be disabled on all the SVI or routed interfaces where the client subnets reside
   • CIP helper-addresses for the client ranges must be disabled on the SVI or routed interface where the WoL server subnet resides
   • DIP helper-addresses for the WoL server must be enabled on the SVI or routed interface where the client subnets reside
   • EIP helper-addresses for the client ranges must be enabled on the SVI or routed interface where the WoL server subnet resides

8. Question 198 · 359 in bank

   In Cisco SD-Access, virtual networks create segmentation that allows for separation of users and resources. How is this type of segmentation described?

   • Astretched
   • Bmicro
   • Cmacro
   • Dinter-VN

   Show answer

   Answer: C

   Explanation

   Answer is correct Macro vs Micro Segmentation Network segmentation can be divided into two main categories: macro segmentation and micro segmentation. Macro segmentation is the process of dividing the network into larger segments based on factors such as geography, department, or function. This is usually achieved through traditional methods such as VRF, VLANs, or firewall zoning. Micro segmentation, in contrast, involves dividing the network into smaller, more granular segments based on individual workloads or applications. This is typically accomplished using software-defined methods such as Security Group Tags (SGTs). Micro segmentation provides more granular control over traffic flows, enabling organizations to reduce the attack surface of the network by limiting the lateral movement of threats. By implementing micro segmentation, organizations can improve their security posture and better protect their critical assets. https://learningnetwork.cisco.com/s/article/software-defined-segmentation-a-primer#:~:text=Macro%20vs%20Micro%20Segmentation,better%20protect%20their%20critical%20assets.

    Refer to the exhibit. A company specializing in VoD content creation has two offices in a separate multicast domain connected by a WAN link. BGP communication has been established between the offices. Clients are inside the LAN in each office. In AS5373, R2 has been selected as RP. What must the network architect design to deliver VoD content to clients in AS65773?

    • APIM SSM
    • BPIM ASM with BSR
    • CMSDP
    • DPIM ASM with Auto-RP

    Show answer

    Answer: C

    Explanation

    Given the network setup and the requirements, Multicast Source Discovery Protocol (MSDP) is the appropriate solution to deliver VoD content to clients across different multicast domains (AS5373 and AS65773)
