  Which component of the Cisco SDN solution serves as the centralized management system?

  A. Cisco OpenDaylight
  B. Cisco ACI
  C. Cisco APIC
  D. Cisco IWAN

  ---

  Cisco ACI is a comprehensive SDN architecture. This policy-based automation solution supports a business-relevant application policy language, greater scalability through a distributed enforcement system, and greater network visibility. These benefits are achieved through the integration of physical and virtual environments under one policy model for networks, servers, storage, services, and security.

• Question 568:

  Which three are the components of SNMP? (Choose three)

  A. MIB
  B. SNMP Manager
  C. SysLog Server
  D. SNMP Agent
  E. Set
  A. MIB
  B. SNMP Manager
  D. SNMP Agent

  ---

  SNMP is an application-layer protocol that provides a message format for communication between SNMP managers and agents. SNMP provides a standardized framework and a common language used for the monitoring and management

  of devices in a network.

  The SNMP framework has three parts:

  + An SNMP manager

  + An SNMP agent

  + A Management Information Base (MIB)

  The SNMP manager is the system used to control and monitor the activities of network hosts using SNMP. The most common managing system is called a Network Management System (NMS). The term NMS can be applied to either a dedicated device used for network management, or the applications used on such a device. A variety of network management applications are available for use with SNMP. These features range from simple command-line applications to feature-rich graphical user interfaces (such as the CiscoWorks2000 line of products).

  The SNMP agent is the software component within the managed device that maintains the data for the device and reports these data, as needed, to managing systems. The agent and MIB reside on the routing device (router, access server, or switch). To enable the SNMP agent on a Cisco routing device, you must define the relationship between the manager and the agent.

  The Management Information Base (MIB) is a virtual information storage area for network management information, which consists of collections of managed objects.

• Question 569:

  What are two benefits of using NAT? (Choose two.)

  A. NAT facilitates end-to-end communication when IPsec is enabled.
  B. NAT eliminates the need to re-address all hosts that require external access.
  C. NAT conserves addresses through host MAC-level multiplexing.
  D. Dynamic NAT facilitates connections from the outside of the network.
  E. NAT accelerates the routing process because no modifications are made on the packets.
  F. NAT protects network security because private networks are not advertised.
  B. NAT eliminates the need to re-address all hosts that require external access.
  F. NAT protects network security because private networks are not advertised.

  ---

  By not revealing the internal IP addresses, NAT adds some security to the inside network - > F is correct.

  NAT has to modify the source IP addresses in the packets -> E is not correct.

  Connection from the outside of the network through a "NAT" network is more difficult than a more network because IP addresses of inside hosts are hidden -> C is not correct.

  In order for IPsec to work with NAT we need to allow additional protocols, including Internet Key Exchange (IKE), Encapsulating Security Payload (ESP) and Authentication Header (AH) -> more complex -> A is not correct. By allocating specific public IP addresses to inside hosts, NAT eliminates the need to re- address the inside hosts -> B is correct.

  NAT does conserve addresses but not through host MAC-level multiplexing. It conserves addresses by allowing many private IP addresses to use the same public IP address to go to the Internet -> C is not correct.

• Question 570:

  What is the best way to verify that a host has a path to other hosts in different networks?

  A. Ping the loopback address.
  B. Ping the default gateway.
  C. Ping the local interface address.
  D. Ping the remote network.
  D. Ping the remote network.

  Ping is a tool that helps to verify IP-level connectivity; PathPing is a tool that detects packet loss over multiple-hop trips. When troubleshooting, the ping command is used to send an ICMP Echo Request to a target host name or IP address.

  Use Ping whenever you want to verify that a host computer can send IP packets to a destination host. You can also use the Ping tool to isolate network hardware problems and incompatible configurations. If you call ipconfig /all and receive a

  response, there is no need to ping the loopback address and your own IP address -- Ipconfig has already done so in order to generate the report. It is best to verify that a route exists between the local computer and a network host by first

  using ping and the IP address of the network host to which you want to connect. The command syntax is:

  ping < IP address >

  Perform the following steps when using Ping:

  Ping the loopback address to verify that TCP/IP is installed and configured correctly on the local computer.

  ping 127.0.0.1

  If the loopback step fails, the IP stack is not responding. This might be because the TCP drivers are corrupted, the network adapter might not be working, or another service is interfering with IP. Ping the IP address of the local computer to

  verify that it was added to the network correctly. Note that if the routing table is correct, this simply forwards the packet to the loopback address of 127.0.0.1.

  ping < IP address of local host >

  Ping the IP address of the default gateway to verify that the default gateway is functioning and that you can communicate with a local host on the local network.

  ping < IP address of default gateway >

  Ping the IP address of a remote host to verify that you can communicate through a router.

  ping < IP address of remote host >

  Ping the host name of a remote host to verify that you can resolve a remote host name.

  ping < Host name of remote host >

  Run a PathPing analysis to a remote host to verify that the routers on the way to the destination are operating correctly.

  pathping < IP address of remote host >
