In the present situation, you will find companies laying off their employees without any notice or prior information. They are just receiving an email and the next moment they have no access to the company network. So to avoid all this, you have to keep yourself updated with the new version of technologies and applications. You have to become one of Designing Cisco Enterprise Networks (300-420) certification holders who survived the laying off situation and are still in a great position in their company. You cannot afford to lose it when you need your job the most.

NEW QUESTION # 454
A company's branch location uses redundant routers and links for connectivity to the headquarters. Also, to use the entire available bandwidth, the branch uses a dynamic routing protocol. An architect must design a multicast streaming solution to avoid RPF check failures because of the current network design. Which deployment model must the architect choose?
Answer: D
NEW QUESTION # 455
Drag and drop the elements from the left onto the protocols where they are used on the right.
Answer:
Explanation:
Explanation:
The drag-and-drop mapping identifies which elements belong to each model-driven protocol or data-modeling mechanism. Cisco programmability designs distinguish the data model, the encoding, and the transport protocol. YANG defines the structure of configuration and operational data. NETCONF commonly uses XML encoding and provides transactional operations such as get-config, edit-config, lock, and commit-like workflow depending on platform support. RESTCONF exposes YANG-modeled data through HTTP methods and typically uses URI-based resources with XML or JSON encoding. gRPC and gNMI are commonly used for efficient telemetry or operational data streaming, with protocol buffers often used for serialization. The selected mapping follows those protocol boundaries rather than mixing model structure with transport behavior. In design work, this matters because the same network feature can be represented by a YANG model but accessed through different protocols, each with different capabilities, security requirements, and operational semantics. Correctly matching elements to protocols avoids invalid payloads and broken automation workflows. Reference topics: YANG, NETCONF, RESTCONF, gRPC, gNMI, XML and JSON encoding, model-driven telemetry.
NEW QUESTION # 456
Refer to the exhibit.
Refer to the exhibit. A network engineer with an employee ID: 4384:99:754 must design a BGP solution based on these conditions:
Traffic sessions occur between the branches and the data center.
Branch B has limited resources to process routing updates.
HQ must filter out all prefixes from branch A to R4.
Which outbound route filtering (ORF) solution must the engineer choose?
Answer: C
NEW QUESTION # 457
Refer to the exhibit. A customer has two eBGP peerings from a single CE router toward two service providers. The customer has hired an architect to design a solution to ensure certain traffic enters the customer's network through interface gig0/0. Which solution must the architect include in the design?
Answer: B
NEW QUESTION # 458
An architect is designing a network solution for a customer The network is IPv6-only with 1000 hosts. The design must provide external access to up to 10 concurrent IPv6 hosts to allow communication with legacy IPv4 devices on an adjacent network. The customer set aside 10 IPv4 addresses to allow for one-to-one communication between hosts. Which solution must the architect select ?
Answer: C
Explanation:
Stateful NAT64 is the correct design because IPv6-only hosts must communicate with legacy IPv4 devices and only a small pool of IPv4 addresses is available for concurrent sessions. NAT64 translates IPv6 client traffic into IPv4 traffic, allowing IPv6-only endpoints to reach IPv4-only resources. A stateful implementation maintains translation state and can use a pool of IPv4 addresses for multiple IPv6 clients, which fits the requirement for up to 10 concurrent IPv6 hosts using 10 reserved IPv4 addresses. Static NAT- PT would require fixed one-to-one mappings and is less suitable for a pool-based concurrent access model. NAT66 translates between IPv6 prefixes and does not solve access to IPv4-only devices. Dynamic NAT-PT is an older transition mechanism and is not the preferred modern answer when NAT64 is available. The design should also include DNS64 when clients access IPv4-only services by name. Reference topics: IPv6 transition, stateful NAT64, DNS64, IPv6-only hosts, IPv4 legacy reachability.
