Cisco Application Centric Infrastructure for System Engineers

Question No: 31

Which three authentication protocols can be configured in the Cisco Application Policy

Infrastructure Controller? (Choose three.)

  1. CHAP

  2. EAP

  3. TACACS

  4. RADIUS

  5. Kerberos

  6. DIAMETER

  7. LDAP

Answer: C,D,G

Reference: http://www.cisco.com/c/en/us/solutions/collateral/data-center- virtualization/unified-fabric/white-paper-c11-730021.html (System Access: Authentication, Authorization, and RBAC)

The Cisco APIC supports both local and external authentication and authorization (TACACS , RADIUS, Lightweight Directory Access Protocol [LDAP]) as well as role-based administrative control (RBAC) to control read and write access for all managed objects and to enforce Cisco ACI administrative and per-tenant administrative separation. The Cisco APIC also supports domain-based access control, which enforces where (under which subtrees) a user has access permissions.

Question No: 32

What is accomplished when you install a bounce entry in a leaf?

  1. Eliminate loops

  2. Forward GARP packets

  3. Redirect traffic to old VTEP destination

  4. Redirect traffic to new VTEP destination

Answer: D

Explanation: Under a normal migration, when a VM moves due to vMotion onto a leaf that does not have those EPGs and VLANs programmed, the will be deployed immediately. vCenter/ESXI host will send a GARP to ACI, the old leaf will bounce traffic to the new location of the endpoint and traffic/learning will occur. The bounce entry will stick around for a bit (about 5 minutes) and then be removed. The EPGs, VLANs, and Default Gateway will be deployed as soon as the move is detected and there will be little to no downtime (i usually see 0-1 ping loss, most of the time just increased latency)

Question No: 33

In which two ways can the Cisco Application Policy Infrastructure Controller push policies to the leaf nodes? (Choose two.)

  1. On demand (lazy)

  2. Immediate

  3. Static

  4. Programmed

  5. Scheduled

Answer: A,B

Reference: http://www.cisco.com/c/en/us/solutions/collateral/data-center- virtualization/application-centric-infrastructure/white-paper-c11-731961.html

When a virtual endpoint is discovered, the policy is pushed and programmed to the leaf nodes based on resolution immediacy and instrumentation immediacy, respectively. In both cases, there is an immediate and on-demand (default) option that is defined when the VMM is associated on Cisco APIC. The on-demand option conserves resources and uses the reserved space in the policy content-addressable memory (CAM) when needed.

Resolution Immediacy

The first option to push a policy is immediately. All policies (VLAN, NVGRE, and VXLAN), bindings, contracts, and filters are pushed to the leaf node when the hypervisor physical NIC (pfJIC) is attached. With the on-demand option, policies are pushed to the leaf node when the pPJIC and vNIC are attached to the port group (EPG).

Deployment Immediacy

Deployment immediacy defines when the policy is programmed in hardware. If the immediate option is chosen, the policies are programmed in the policy CAM after they are received by Cisco APIC. The on-demand option programs policies in the hardware policy CAM only when reachability is learned through the data path.

Question No: 34
