  You are configuring an L3Out interface for a VRF for which OSPF is configured on an ACI fabric. You notice that the OSPF routing table us rebuilt every 10 seconds. Which reason for this behavior is true?

  A. A duplex mismatch is on the link on which L3out is configured.
  B. The loopback interfaces of the L3Out are configured with an IP addresses that is already in use.

• Question 302:

  In which three ways can you house Edge Transport servers on their perimeter network in ACI without investing extra cost in buying additional hardware? (Choose three.)

  A. Create an L3Out to route peer with an ASA firewall to isolate traffic with security rules
  B. Create a private VRF with default enforcement policy. Configure a bridge domain with a subnet assigned to a private VRF.
  C. No need to create Contracts. A default enforcement policy allows all traffic to forward.
  D. Choose options "Shared Route Control Subnet" and "Shared Import Security Subnet".
  E. Create Contract to enforce policy between Edge Transport servers EPG and backend mailbox servers EPG.
  A. Create an L3Out to route peer with an ASA firewall to isolate traffic with security rules
  B. Create a private VRF with default enforcement policy. Configure a bridge domain with a subnet assigned to a private VRF.
  C. No need to create Contracts. A default enforcement policy allows all traffic to forward.

  B. After the first successful authentication, the username and password are used with the session cookie to bypass performing the full authentication process again.
  C. Expiration time of the nxapi_auth cookie can be changed up to the maximum of 1200 seconds.
  D. After the first successful authentication, the username and password are NOT included in subsequent NX-API requests that are sent to the device.
  E. NX-API performs authentication through a programmable authentication module on the switch. Using cookies reduces the number of PAM authentications, which reduces the load on the PAM.
  F. The nxapi_auth cookie expires in 600 seconds.
  B. After the first successful authentication, the username and password are used with the session cookie to bypass performing the full authentication process again.
  E. NX-API performs authentication through a programmable authentication module on the switch. Using cookies reduces the number of PAM authentications, which reduces the load on the PAM.
