NEW QUESTION # 315
A network architect Is enabling TV services In the LAN. The source will be streaming to the 239.1.1.1 group IP address. Dense mode Is not allowed In the network. Multicast has already been enabled on all network devices In the LAN segment. Which action must the architect take to finalize the design?
Answer: A
Explanation:
PIM BSR is the best final design action because the source uses group 239.1.1.1, which is an administratively scoped ASM multicast group, and dense mode is not allowed. In PIM sparse mode, ASM groups require a rendezvous point so receivers can join the shared tree and sources can register. PIM SSM is not the right match for 239.1.1.1 because SSM normally uses the 232.0.0.0/8 group range and requires receivers to know the source address. Auto-RP can distribute RP information, but traditional Auto-RP discovery relies on multicast groups that often require sparse-dense behavior, which conflicts with the requirement that dense mode is not allowed. BSR is the standards-based PIM mechanism for dynamic RP discovery in sparse-mode networks and avoids static RP configuration on every router. Anycast RP is an RP redundancy design but still requires RP discovery or static RP configuration. Reference topics: PIM sparse mode, Bootstrap Router, ASM, RP discovery, administratively scoped multicast.
NEW QUESTION # 316
What is the purpose of a border node in a Cisco SD-Access fabric?
Answer: B
Explanation:
The border node provides connectivity between the SD-Access fabric and networks outside the fabric. In Cisco SD-Access, edge nodes connect endpoints to the fabric, intermediate nodes transport routed IP traffic through the underlay, control-plane nodes maintain endpoint location mappings, and border nodes connect the fabric to external Layer 3 domains such as the data center, WAN, internet edge, or shared services network. A border node may perform proxy tunnel router functions and can de-encapsulate fabric traffic that is destined outside the overlay, but its design purpose is external connectivity for the fabric site. Network virtualization is primarily delivered through virtual networks, VRF separation, LISP control-plane mappings, and VXLAN encapsulation. Expanding the network is too vague and does not identify a Cisco SD-Access role. Therefore, among the available options, the border node is the component used to connect the fabric to the required external network resources. Reference topics: Cisco SD-Access border node, external connectivity, fabric roles, LISP proxy tunnel router, VN-to-VRF mapping.
NEW QUESTION # 317

Answer: B
NEW QUESTION # 319
A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?
Answer: D
Explanation:
Periodic updates contain a full copy of the subscribed data element or table for all supported transport protocols.
