  default-information originate

  To generate a default external route into an Open Shortest Path First (OSPF) routing domain, use the default-information originate command in router configuration mode. To disable this feature, use the no form of this command. default-

  information originate [always] metric metric-value [ metric-type type-value ] [ route-map map-name ]

  Syntax Description

  always

  (Optional) Always advertises the default route regardless of whether the software has a default route.

• Question 364:

  Which two actions can you take to allow the greatest number of pertinent packets to be stored in the temporary buffer of Cisco IOS Embedded Packet Capture? (Choose two.)

  A. Specify the sampling interval.
  B. Specify the capture buffer type.
  C. Specify a reflexive ACL.
  D. Specify the minimum packet capture rate.
  E. Specify the packet size.
  F. Store the capture simultaneously onto an external memory card as the capture occurs.
  A. Specify the sampling interval.
  B. Specify the capture buffer type.

  Embedded Packet Capture (EPC) provides an embedded systems management facility that helps in tracing and troubleshooting packets. This feature allows network administrators to capture data packets flowing through, to, and from a Cisco device. The network administrator may define the capture buffer size and type (circular, or linear) and the maximum number of bytes of each packet to capture. The packet capture rate can be throttled using further administrative controls. For example, options allow for filtering the packets to be captured using an Access Control List and, optionally, further defined by specifying a maximum packet capture rate or by specifying a sampling interval.

  Which two configuration changes enable you to log in to the router? (Choose two.)

  A. Configure a user name and password on the device.
  B. Modify the default login authentication group to use the terminal line password.
  C. Remove the terminal line password on the console line.
  D. Modify the terminal lines to include transport input none.
  E. Configure the terminal lines to use the local user database.
  A. Configure a user name and password on the device.
  B. Modify the default login authentication group to use the terminal line password.

• Question 366:

  Which option is the result if two adjacent routers are configured for OSPF with different process IDs?

  A. The routers are unable to establish an adjacency.
  B. The routers establish an adjacency, but route exchange fails.
  C. The routers establish an adjacency and exchange routes, but the routes are unreachable.
  D. The routers establish an adjacency and exchange routes, and the routes are reachable.
  D. The routers establish an adjacency and exchange routes, and the routes are reachable.

• Question 367:

  Refer to the exhibit.

  

  If a Layer 3 switch running OSPF in a VRF-lite configuration reports this error, which action can you take to correct the problem?

  A. Set mls cef maximum-routes in the global configuration.
  B. Add the vrf-lite capability to the OSPF configuration.
  C. Upgrade the Layer 3 switch to a model that can support more routes.
  D. Configure the control plane with a larger memory allocation to support the Cisco Express Forwarding Information Base.
  A. Set mls cef maximum-routes in the global configuration.

• Question 368:

  Which three statements about implementing a NAT application layer gateway in a network are true? (Choose three.)

  A. It allows client applications to use dynamic ports to communicate with a server regardless of whether NAT is being used.
  B. It maintains granular security over application-specific data.
  C. It allows synchronization between multiple streams of data between two hosts.
  D. Application layer gateway is used only in VoIP/SIP deployments.
  E. Client applications require additional configuration to use an application layer gateway.
  F. An application layer gateway inspects only the first 64 bytes of a packet before forwarding it through the network.
  A. It allows client applications to use dynamic ports to communicate with a server regardless of whether NAT is being used.
  B. It maintains granular security over application-specific data.
  C. It allows synchronization between multiple streams of data between two hosts.

  An application-level gateway (ALG), also known as an application-layer gateway, is an application that translates the IP address information inside the payload of an application packet. An ALG is used to interpret the application-layer protocol and perform firewall and Network Address Translation (NAT) actions. These actions can be one or more of the following depending on your configuration of the firewall and NAT: Allow client applications to use dynamic TCP or UDP ports to communicate with the server application. Recognize application-specific commands and offer granular security control over them. Synchronize multiple streams or sessions of data between two hosts that are exchanging data. Translate the network-layer address information that is available in the application payload Reference: http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_nat/configuration/xe- 3s/asr1000/ nat-xe-3s-asr1k-book/fw-msrpc-supp.html

• Question 369:

  In a Cisco ACI environment, which option best describes "contracts"?

  A. a set of interaction rules between endpoint groups
  B. a Layer 3 forwarding domain
  C. to determine endpoint group membership status
  D. named groups of related endpoints
  A. a set of interaction rules between endpoint groups

• Question 370:

  Refer to the exhibit.

  

  While configuring AAA with a local database, users can log in via Telnet, but receive the message "error in authentication" when they try to go into enable mode. Which action can solve this problem?

  A. Configure authorization to allow the enable command.
  B. Use aaa authentication login default enable to allow authentication when using the enable command.
  C. Verify whether an enable password has been configured.
  D. Use aaa authentication enable default enable to allow authentication when using the enable command.
  C. Verify whether an enable password has been configured.

  ---

  If a different enable password is configured, it will override the privilege level 15 of that user and force the existing password to be used for enable access.
