  C. source 192.168.10.10 and destination 192.168.20.10

  ---

  The source and destination IP addresses of the packets are unchanged on all the way. Only source and destination MAC addresses are changed.

• Question 1652:

  Which IPsec encryption mode is appropriate when the destination of a packet differs from the security termination point?

  A. transport
  B. main
  C. aggressive
  D. tunnel
  D. tunnel

• Question 1653:

  When using Rapid PVST+, which command guarantees the switch is always the root bridge for VLAN 200?

  A. spanning -tree vlan 200 priority 614440
  B. spanning -tree vlan 200 priority 38572422
  C. spanning -tree vlan 200 priority 0
  D. spanning -tree vlan 200 root primary
  C. spanning -tree vlan 200 priority 0

  ---

  About root primary command:

  https://community.cisco.com/t5/switching/spanning-tree-vlan-root-primary/td-p/1269595

  Paraphrasing from this source:

  The "spanning-tree root primary" command is actually a macro and it is executed only one time. If after this somebody configures another device with a lower priority, this node cannot react to this and it will lose its root bridge role. If you use "spanning-tree vlan 1 priority 0", only another device with pri 0 and a lower MAC address can take the role of root bridge.

• Question 1654:

  When a WPA2-PSK WLAN is configured in the Wireless LAN Controller, what is the minimum number of characters that is required in ASCII formar?

  A. 6
  B. 8
  C. 12
  D. 18
  B. 8

  ---

  WPA preshared keys must contain 8 to 63 ASCII text characters or 64 hexadecimal characters.

• Question 1655:

  What is represented by the word "port" within this JSON schema?

  

  A. key
  B. value
  C. array
  D. object
  A. key

  ---

  Within this JSON schema, the word "port" is a key within the objects represented by the curly braces {}. Each object in the schema has two key-value pairs, where "port" is one of the keys.

• Question 1656:

  Which REST method updates an object in the Cisco DNA Center Intent API?

  A. CHANGE
  B. UPDATE
  C. POST
  D. PUT
  D. PUT

  ---

  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.

• Question 1657:

  DRAG DROP

  Drag drop the descriptions from the left onto the correct configuration-management technologies on the right.

  Select and Place:

  

  

• Question 1658:

  Which field in an Ethernet frame identifies the upper-layer protocol?

  A. Preamble
  B. Type
  C. FCS
  D. Source address
  B. Type

  ---

  The Type field in an Ethernet frame indicates which upper-layer protocol is encapsulated in the frame, such as IPv4, IPv6, or ARP.

• Question 1659:

  What is a function of store-and forward switching?

  A. It reduces latency by eliminating error checking within the frame
  B. It produces an effective level of error-free network traffic using CRCs.
  C. It buffers frames and forwards regardless of errors within the frames.
  D. It forwards a frame by checking only the destination MAC address
  B. It produces an effective level of error-free network traffic using CRCs.

• Question 1660:

  Refer to the exhibit. Which plan must be Implemented to ensure optimal QoS marking practices on this network?

  

  A. As traffic traverses MLS1 remark the traffic, but trust all markings at the access layer.
  B. Trust the IP phone markings on SW1 and mark traffic entering SW2 at SW2.
  C. Remark traffic as it traverses R1 and trust all markings at the access layer.
  D. As traffic enters from the access layer on SW1 and SW2. trust all traffic markings.
  B. Trust the IP phone markings on SW1 and mark traffic entering SW2 at SW2.

  Tell the switch to trust CoS markings from a Cisco IP phone on the access port. Cisco IP phones use 802.1q tags, these .1q tags contain the CoS value, to mark voice traffic at layer 2. When it's forwarded upstream, the DSCP value is trusted (on the uplink port) and unchanged, but the .1q tag (and with it the CoS value) is stripped off by the upstream switch when received over the trunk.
