NEW QUESTION # 410 
Refer to the exhibit. An engineer must design an address translation solution to provide Internet connectivity for the corporate network. The design Is restricted to the 172.16.168.0/22 subnet. Which solution must the engineer choose?
Answer: C
Explanation:
Stateful NAT64 is the correct translation solution when IPv6-only corporate hosts need Internet connectivity to IPv4 resources using a limited IPv4 address pool. NAT64 translates IPv6 client addresses to IPv4 addresses and maintains state for each session, allowing many IPv6 hosts to share a smaller set of IPv4 addresses through port multiplexing. The design is restricted to the 172.16.168.0/22 subnet, which provides an IPv4 pool that can be used for stateful translation. Stateless NAT64 requires algorithmic one-to-one address mapping and normally needs enough IPv4 address space to represent IPv6 hosts deterministically; it is not suitable when many clients must share a restricted IPv4 block. NAT66 translates IPv6 to IPv6 and does not provide access to IPv4 Internet resources. In a production design, stateful NAT64 is often paired with DNS64 so IPv6-only clients can resolve IPv4-only destinations through synthesized AAAA records. Reference topics:
stateful NAT64, DNS64, IPv6-to-IPv4 translation, address conservation, Internet access migration.
NEW QUESTION # 411
In Cisco SD-Access. virtual networks create segmentation that allows for separation of users and resources.
How is this type of segmentation described?
Answer: A
Explanation:
Virtual networks in Cisco SD-Access provide macro segmentation. Macro segmentation separates major user, device, or service groups into distinct virtual networks, each with its own routing and forwarding context.
This is comparable to VRF-based separation in traditional enterprise designs. For example, corporate users, guests, building systems, and IoT devices can be placed into separate virtual networks so their routing domains remain isolated unless controlled inter-VN communication is explicitly provided. Microsegmentation is different; it is normally enforced inside or across virtual networks using Security Group Tags and Security Group ACLs, allowing policy decisions based on group identity rather than only IP subnets or VLANs. Inter- VN describes communication between virtual networks, not the segmentation type itself. Stretched segmentation is not the standard SD-Access term. Therefore, the separation created by virtual networks is macro segmentation, while SGT-based policy provides finer-grained microsegmentation. Reference topics:
Cisco SD-Access virtual networks, macro segmentation, VRF, SGT, microsegmentation, policy enforcement.
NEW QUESTION # 412
A network engineer must design a multicast solution to prevent the spoofing of multicast streams and ensure efficient bandwidth utilization. The network will be merged with another multicast domain in the future, and the merge must require minimum effort. Which two solutions meet the customer requirements? (Choose two.)
Answer: D,E
NEW QUESTION # 413
Drag and drop the characteristics from the left onto the correct telemetry mode on the right.
Answer:
Explanation:
Explanation
In a dial-in mode, the destination initiates a session to the router and subscribes to data to be streamed. Dialin mode is supported over gRPC in only 64-bit platforms In a dial-out mode, the router initiates a session to the destinations based on the subscription. All 64-bit IOS XR platforms (except for NCS 6000 series routers) support gRPC and TCP protocols. All 32-bit IOS XR platforms support only TCP.
NEW QUESTION # 414
What is the purpose of a border node in a Cisco SD-Access fabric?
Answer: C
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.
