When a site-to-site VPN is used, which protocol is responsible for the transport of user data?
A. IKEv2
B. IKEv1
C. IPsec
D. MD5
Explanation:
A site-to-site VPN allows offices in multiple fixed locations to establish secure
connections with each other over a public network such as the Internet. A site-to-site VPN
means that two sites create a VPN tunnel by encrypting and sending data between two
devices. One set of rules for creating a siteto-site VPN is defined by IPsec

Which REST method updates an object in the Cisco DNA Center Intent API?
A. CHANGE
B. UPDATE
C. POST
D. PUT
Explanation:
PUT is most-often utilized for **update** capabilities, PUT-ing to a known
resource URI with the request body containing the newly-updated representation of the
original resource.However, PUT can also be used to create a resource in the case where
the resource ID is chosen by the client instead of by the server. In other words, if the PUT
is to a URI that contains the value of a non-existent resource ID. Again, the request body
contains a resource representation. Many feel this is convoluted and confusing.
Consequently, this method of creation should be used sparingly, if at all.Alternatively, use
POST to create new resources and provide the client-defined ID in the body
representation—presumably to a URI that doesn’t include the ID of the resource (see
POST below).On successful update, return 200 (or 204 if not returning any content in the
body) from a PUT. If using PUT for create, return HTTP status 201 on successful creation.
A body in the response is optional—providing one consumes more bandwidth. It is not
necessary to return a link via a Location header in the creation case since the client already
set the resource ID.PUT is not a safe operation, in that it modifies (or creates) state on the
server, but it is idempotent. In other words, if you create or update a resource using PUT
and then make that same call again, the resource is still there and still has the same state
as it did with the first call.If, for instance, calling PUT on a resource increments a counter
within the resource, the call is no longer idempotent. Sometimes that happens and it may
be enough to document that the call is not idempotent. However, it’s recommended to keep
PUT requests idempotent. It is strongly recommended to use POST for non-idempotent
requests.Examples:
