What is a consideration when designing a Cisco SD-Access underlay network?
Answer: D
D is correct : "In SD-Access, the underlay switches (edge nodes) support the physical connectivity for users and endpoints. However, end-user subnets and endpoints are not part of the underlay network—they are part of the automated overlay network."

Which entity is a Type 1 hypervisor?
Answer: B
Which NTP concept is used to measure the distance from a device to its authoritative time source?
Answer: A
In a Cisco SD-Access environment, which function is performed by the border node?
Answer: D
Fabric border node: This fabric device (for example, core layer device) connects external Layer 3 networks to the SDA fabric

What is a characteristic of the overlay network in the Cisco SD-Access architecture?
Answer: B
In Cisco SD-Access, the overlay network is designed to abstract and provide independence from the underlying physical network. It enables segmentation, policy enforcement, and logical network isolation without direct dependence on the physical network topology. This characteristic contributes to the flexibility and programmability of SD-Access.

What gives priority on an egress interface, for database traffic that connected on an ingress interface, without changing the CoS value?
Answer: B
Given that you need a policy map to use QoS groups, and QoS groups themselves can only affect the ingress interface (whereas policy maps can be placed on the egress as well), I think B makes more sense, even if QoS groups can influence how the policy map treats the traffic. "A policy map containing the set qos-group command can only be attached as an input traffic policy. QoS group values are not usable for traffic leaving a device." https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/qos_classn/configuration/xe-16/qos-classn-xe-16-book/qos-classn-grp-mtch-set.html

Why are stateless calls executed by REST API useful in cloud applications?
Answer: C
C. They are easy to redeploy and to scale. Stateless calls in REST APIs are useful in cloud applications because they do not rely on session information stored on the server. Each request from the client contains all the information the server needs to fulfill that request. This makes it easy to scale and redeploy services across multiple servers or environments, as no session state needs to be shared or maintained between requests.

What are two benefits of virtual switching when compared to hardware switching? (Choose two.)
Answer: DE
What are two benefits of virtual switching when compared to hardware switching? (Choose two.) A. increased MTU size ==> WRONG, can be modified on both types B. VM-level isolation ==> WRONG, please see explanation below marked * C. extended 802.1Q VLAN range ==> WRONG VLAN Range is defined by protocol not switch type D. hardware independence ==> CORRECT, hence virtual E. increased flexibility ==> CORRECT, have you ever added 52 ports to a physical switch with just a few clicks and no purchase orders and lots of approvals for money ? ?? * Explanation What is VM based isolation? Image result for what is vm-level isolation virtual switch A VM is an isolated environment with access to a subset of physical resources of the computer system. Each VM appears to be running on the bare hardware, giving the appearance of multiple instances of the same computer, though all are supported by a single physical system.

Refer to the exhibit. What does the response "204 No Content" mean for the REST API request?
Answer: A
A 204 status code is used when the server successfully processes the request, but there is no content to return to the client. This is typically used for requests where the client wants to indicate that it has finished processing a request, such as a DELETE request
