Question 1

Explanation

For campus designs requiring simplified configuration, common end-to-end troubleshooting tools, and the fastest convergence, a design using Layer 3 switches in the access layer (routed access) in combination with Layer 3 switching at the distribution layer and core layers provides the most rapid convergence of data and control plane traffic flows.

Reference: https://www.cisco.com/c/en/us/td/docs/solutions/CVD/Campus/cisco-sda-design-guide.html#Layer_3_Routed_Access_Introduction

Campus fabric runs over arbitrary topologies:
+ Traditional 3-tier hierarchical network
+ Collapsed core/aggregation designs
+ Routed access
+ U-topology

Ideal design is routed access –allows fabric to extend to very edge of campus network

Reference: https://www.ciscolive.com/c/dam/r/ciscolive/us/docs/2017/pdf/BRKCRS-2812.pdf

From above references, we see that campus infrastructure does not include two-tier topology.

Question 2

Question 3

Explanation

The difference between on-premise and cloud is essentially where this hardware and software resides. On-premise means that a company keeps all of this IT environment onsite either managed by themselves or a third-party. Cloud means that it is housed offsite with someone else responsible for monitoring and maintaining it.

Question 4

Question 5

Explanation

Stateful Switchover (SSO) provides protection for network edge devices with dual Route Processors (RPs) that represent a single point of failure in the network design, and where an outage might result in loss of service for customers.

    Just to be clear,
    are the part 1 to 3 under ENCOR topics? So do we need to learn both ENCOR specific topics and Parts 4 to 7?

    thank you

    @webmaster you have to study all of the contents inside the digitaltut not only part4-7

    Where is the question for this?

    @digitaltut the correct answer is “routed access”.
    Question 1 : A company plans to implement intent-based networking in its campus infrastructure…

    @AlphaSierra: Thanks for your detection, we updated Q1.

    if you look at the official book, the “two-tier” is also considered as a possible architecture.

    1: Which design facilities a migrate from a traditional campus design to a programmer fabric designer?

    2: Which design facilitates a migration from a traditional campus design to a programmable fabric design?

    Which one is correct?

    Question 5; shouldn’t the answer be NSF/NSR?

    So all new questions or updates goes to part 8 onwards? The previous parts remains the same?

    @Zeze SSO is the mechanism, NSF/NSR is a function within SSO.

    * NSF requires SSO
    * NSF works with SSO to minimize the amount of time a network is unavailable to its users following a
    switchover. The main objective of Cisco NSF is to continue forwarding IP packets following a route processor (RP) switchover.

    Thank you to digitaltut.com.

    Hello,
    Can you please let me know if the questions are still valid? I need to take the CCNP encore next week.
    Thanks.

    Are all of the questions on 350-401 covered within this if a person subscribes?

    Why do you have to choose between NSF and SSO in Q5? What the hell? They run together to ensure packets are not dropped, I chose NSF NSR

    I just passed the exam. All questions are here.
    94 questions including 4 sims (HSRP, logging and netflow, portchannel and native vlan, and BGP neighbor). Thanks @digitaltut
