   Explanation

   given answers are incorrect daemon that determines when the central authority has updates available == Agent model in which the central server sends updates to nodes on an as-needed basis == push easy-to-manage deployment option that may lack scalability == provision device hardware that runs without embedded management features == agentless to automatically install or deploy a configuration or update == pull Auto Update Server (AUS) enables you to upgrade device configuration files and Adaptive Security Appliance (ASA) devices that use the auto update feature. AUS supports a pull model of configuration that you can use for device configuration, configuration updates. https://www.cisco.com/c/en/us/td/docs/security/security_management/cisco_security_manager/security_manager/425/deployment/deployment_planning_guide-425.html https://dev.to/anubhavitis/push-vs-pull-api-architecture-1djo

5. Question 35 · 1334 in bank

   Which interface type enables an application running on a client to send data over an IP network to a server?

   • Anorthbound interface
   • Bapplication programming interface
   • Csouthbound interface
   • DRepresentational State Transfer application programming interface

   Show answer

   Answer: B

   Explanation

   The correct answer is B. application programming interface (API). An application programming interface (API) is a set of rules and protocols that allows different software applications to communicate and interact with each other. In the context of sending data over an IP network from a client to a server, an API provides the necessary methods and functions for the client application to establish a connection, format and send the data packets, and communicate with the server. While northbound and southbound interfaces are also valid terms used in networking, they typically refer to the interfaces used in network management and communication between different layers of a network architecture. The Representational State Transfer (REST) API is a specific type of API that uses HTTP protocols and follows the principles of RESTful architecture for creating web services, but it is not the only type of API that enables data transfer over an IP network.

9. Question 39 · 1334 in bank

   What does traffic shaping do?

   • AIt queues excess traffic
   • BIt sets QoS attributes within a packet
   • CIt organizes traffic into classes
   • DIt modifies the QoS attributes of a packet

   Show answer

   Answer: A

   Explanation

   A is correct: Traffic policing and traffic shaping have the following differences: Traffic policing directly discards packets with rates that are greater than the traffic policing rate. Traffic shaping, however, buffers packets with rates that are greater than the traffic shaping rate and sends the buffered packets at an even rate.

10. Question 40 · 1334 in bank

    

    Refer to the exhibit. A Cisco engineer is asked to update the configuration on switch 1 so that the EtherChannel stays up when one of the links fails. Which configuration meets this requirement?

    • ASwitch1(config) # interface Fa0/0 Switch1(config-if) # lacp port-priority 100 Switch1(config) # interface Fa0/1 Switch1(config-if) # lacp port-priority 200
    • BSwitch1(config) # interface port-channel 1 Switch1(config-if) # port-channel min-links 1
    • CSwitch1(config) # interface Fa0/0 Switch1(config-if) # lacp port-priority 200 Switch1(config) # interface Fa0/1 Switch1(config-if) # lacp port-priority 100
    • DSwitch1(config) # interface port-channel 1 Switch1(config-if) # lacp max-bundle 1

    Show answer

    Answer: B

    Explanation

    min-links command specifies the minimum number of interfaces that the configuration mode LAG requires to be active. If there are fewer ports than specified by this command, the port channel interface does not become active.
