  Cisco DNA Center is a complete management and control platform that simplifies and streamlines network operations. This single, extensible software platform includes integrated tools for AIOps, NetOps, SecOps, DevOps, and Internet-of-Things (IoT) connectivity with AI/ML technology integrated throughout. Functionality this complete could be achieved before now only through the purchase and operation of multiple third-party software tools. The advantages of having all your core network tools integrated into a single software platform are compelling:

  1. Multiple tools with multiple interfaces add complexity, which increases the possibility of errors in configuration and management. This can be especially damaging when errors in security settings lead to open vulnerabilities.

  2. Changing between program interfaces during network operations is time consuming and can make even simple changes or troubleshooting tasks take much longer to complete.

  3. Third-party platforms will never support the same levels of device management and control as those that are integrated and designed to work together.

  4. Automatic troubleshooting with guided remediation is extremely complex in today's virtualized networks. Third-party tools can often tell you if a problem is due to the network or caused by an application, but they cannot offer guided remediation without true integration between the tools that control virtualization, analytics, and automation.

  5. Provides deep insight into user experience for Apple iOS devices, Samsung smart phones, and devices using Intel® Wi-Fi chipsets.

  6. Wireless performance optimization is achieved through a number of powerful capabilities: 3D heatmaps that are immersive tools allowing the user to gain insight into current wireless coverage; a “what if” planning tool that models for additional capacity or coverage changes; intelligent packet capture; and a set of industry-leading AI/ML-driven wireless analytics tools.

  7. Real intent-based networking requires extensive real-time data flow between the operational tools that are at the core of the network. The management of network configuration, security, analytics, and automation comes together to deliver the operation's true business intent. Core management tools supplied by multiple third-party vendors cannot efficiently share, and react to, the amounts of data and critical information required to deliver a genuine intent-based network experience.

  8. Cisco DNA Center is an open and extensible platform that allows third-party applications and processes to exchange data and intelligence with your network. This improves IT operations by automating workflow processes based on network intelligence coming from Cisco DNA Center.

  9. Cisco DNA Center is FIPS 140-2 compliant. Federal government departments and public- and private-sector organizations can be assured of compliance with security mandates for protecting sensitive information.

• Question 1365:

  Refer to the exhibit.

  

  Traffic from R1 to the 10.10.2.0/24 subnet uses 192.168.1.2 as its next hop. An network engineer wants to update the R1 configuration so that traffic with destination 10.10.2.1 passes through router R3, and all other traffic to the 10.10.20/24 subnet passes through R2. Which command must be used?

  A. Ip route 10.10.2.1 255.255.255.255 192.168.1.4 115
  B. Ip route 10.10.2.0 255.255.255.0 192.168.1.4 100
  C. Ip route 10.10.2.0 255.255.255.0 192.168.1.4 115
  D. Ip route 10.10.2.1 255.255.255.255 192.168.1.4 100
  D. Ip route 10.10.2.1 255.255.255.255 192.168.1.4 100

  Here we need to add a host route for the specific 10.10.2.1 host, which means using a subnet mask of 255.255.255.255. We also need to configure an Administrative Distance that is less than the default OSPF AD of 115.

• Question 1368:

  Which purpose does a northbound API serve in a controller-based networking architecture?

  A. facilitates communication between the controller and the applications
  B. reports device errors to a controller
  C. generates statistics for network hardware and traffic
  D. communicates between the controller and the physical network hardware
  A. facilitates communication between the controller and the applications

  ---

  A northbound interface is an interface that allows a particular component of a network to communicate with a higher-level component. Conversely, a southbound interface allows a particular network component to communicate with a lower-level component.

  In a figurative sense, northbound flow can be thought of as going upward, while southbound flow can be thought of as going downward. In architectural diagrams, northbound interfaces are drawn at the top of the applicable component, while southbound interfaces are drawn at the bottom of the component. While the terms northbound and southbound can apply to almost any type of network or computer system, in recent years they have been used increasingly in conjunction with application program interfaces (APIs) in software-defined networking (SDN). In SDN, the southbound interface is the OpenFlow (or alternative) protocol specification. Its main function is to enable communication between the SDN controller and the network nodes (both physical and virtual switches and routers) so that the router can discover network topology, define network flows and implement requests relayed to it via northbound APIs. The northbound interface describes the area of protocol-supported communication between the controller and applications or higher layer control programs.

• Question 1369:

  B. Turn off the logging monitor in global configuration mode.
  C. Disable logging to the console.
  D. Set the logging trap severity level to informational.
  D. Set the logging trap severity level to informational.

• Question 1370:

  Refer to the exhibit.

  

  Which switch in this configuration will be elected as the root bridge?

  SW1: 0:4:87:19:37:17 SW2: 0:0:15:22:05:97 SW3: 0:0:15:1::9D SW4: 0:0:18:1::19

  A. SW1
  B. SW2
  C. SW3
  D. SW4
  C. SW3

  ---

  In a Spanning Tree Protocol (STP) network, the election of the root bridge is based on the Bridge ID, which consists of two components:

  1. Priority (lower is better).

  2. MAC address (lower is better if priorities are the same).

  Breakdown of the exhibit:

  SW1 Priority: 8192

  SW2 Priority: 4096

  SW3 Priority: 4096

  SW4 Priority: 12288

  The election process works as follows:

  First, STP compares the priority values of all switches. The switch with the lowest priority value becomes the root bridge.

  If two switches have the same priority, the switch with the lowest MAC address wins the election.

  Step-by-Step Process:

  SW2 and SW3 have the same priority (4096), which is the lowest among the four switches.

  Since the priorities are the same, the next step is to compare the MAC addresses.

  Given MAC addresses:

  SW2: 0C:0E:15:22:05:97

  SW3: 0C:0E:15:1A:3C:9D

  SW3 has a lower MAC address compared to SW2 because the third byte (1A in SW3) is lower than the corresponding byte (22 in SW2).

  Conclusion:

  SW3 will be elected as the root bridge because it has the lowest priority and lowest MAC address among the switches with the same priority.
