D. network control policy 

Answer:

Q2. Which of the following are true concerning authentication within a Cisco Unified Computing System? 

A. Authentication domains are used to leverage individual authentication systems. 

B. You can create up to 64 authentication domains, each associated with a provider group and realm in Cisco Unified Computing System Manager. 

C. At login, the user can select the authentication domain to be used. 

D. Cisco Unified Computing System supports LDAP or RADIUS for remote authentication. 

E. A locally authenticated user account is authenticated directly through the fabric interconnect. 

Answer:

Q3. Which of the following is true with respect to recovery from failure with automatic pinning that is configured on a cluster of Cisco Unified Computing System 62XX Fabric Interconnects? 

A. By default, server MAC addresses are pinned to uplink interfaces using PIN groups. 

B. When a northbound fabric interconnect link goes down, the affected servers will use NIC teaming to re-establish connectivity on the second fabric interconnect. 

C. When a northbound fabric interconnect link goes down, the fabric interconnect will send a gratuitous ARP to the northbound switch to announce the servers on the new port. 

D. In the event that all uplink ports on the fabric interconnect lose connectivity, the 22XX I/O module shuts down all of the host ports until at least one uplink is restored. 

Answer:

Q4. The Cisco UCS administrator has the chassis discovery policy set to "2-link". The administrator connects a new chassis to the Cisco UCS 6200 Series Fabric Interconnects using four links. Which option about link utilization is true? 

A. The Cisco UCS will use two links until the chassis is reacknowledged, after which it will use all four links. 

B. The Cisco UCS will use all four links for discovery. 

C. The Cisco UCS will use only two links. The other two links are unusable. 

D. The Cisco UCS will use only two links. However, the administrator can manually pin traffic to the extra links by using service profiles.

D. In the LAN cloud on Cisco UCS Manager, define a QoS system class with MTU 9000. 

E. In the service profile, configure MTU 9000 in the vNIC. 

F. In the service profile, configure MTU 9000 in the virtual machine. 

G. In the service profile, configure MTU 9000 in the uplink interfaces. 

Answer: DE
