  Return traffic is policy-based routed back to the SLB.

  Which SLB design has been implemented?

  A. router mode
  B. inline bridge mode
  C. one-armed mode
  D. two-armed mode

  A. zoning
  B. IVR
  C. VSAN
  D. iSCSI
  A. zoning
  C. VSAN

• Question 45:

  Which two options are two benefits of a Layer 2 looped model? (Choose two.)

  A. extends VLANs between switches that are connected to a common aggregation module
  B. prevents uplink ports from entering the spanning-tree blocking state
  C. provides quick convergence with Rapid Spanning Tree Protocol
  D. increases performance to end hosts using directly connected, bonded Layer 2 links
  A. extends VLANs between switches that are connected to a common aggregation module
  C. provides quick convergence with Rapid Spanning Tree Protocol

• Question 46:

  Which two services are provided at the aggregation layer in a data center design? (Choose two.)

  A. service module integration
  B. default gateway redundancy
  C. high-speed packet switching backplane
  D. network interface card teaming
  E. Layer 3 domain definitions
  A. service module integration
  B. default gateway redundancy

• Question 47:

  Which statement about NIC teaming configurations is true?

  A. With ALB, all ports use one IP address and multiple MAC addresses.
  B. With AFT, two NICs connect to the different switches.
  C. With SFT, all ports are active.
  D. With AFT, all ports use one IP address and multiple MAC addresses.
  A. With ALB, all ports use one IP address and multiple MAC addresses.

  ---

  explanation:

  Adapter fault tolerance (AFT): With AFT designs, two NICs connect to the same switch. One adapter is active and the other standby, and they use one common IP address and MAC address.

  Switch fault tolerance (SFT): With SFT designs, one port is active and the other standby, and they use one common IP address and MAC address. Adaptive load balancing (ALB): With ALB designs, one port receives and all ports transmit

  using one IP address and multiple MAC addresses.

• Question 48:

  Which two options are advantages of having a modular design instead of an EOR design in a data center? (Choose two.)

  A. cooling constraints
  B. cable bulk
  C. decreased STP processing
  D. redundancy options
  E. cost minimization
  F. low-skilled manager
  A. cooling constraints
  B. cable bulk

  ---

  explanation:

  There are some disadvantages with EOR designs:

  Cable bulk: More cabling needs to be routed and managed.

  Cooling constraints: The cable bulk at the cabinet floor entry can be difficult to manage and can block cool airflow.

  NOTE for your learnings:

  There are several advantages with EOR designs:

  Decreased management complexity: There are fewer devices to manage, which makes this task less complex. Decreased STP processing: With fewer devices in the Layer 2 infrastructure and significantly fewer uplinks, there is less impact

  on STP processing. Redundancy options: Redundant switch power and CPUs can be supported on modular switches.

• Question 49:

  Which three options are basic design principles of the Cisco Nexus 7000 Series for data center virtualization? (Choose three.)

  A. easy management
  B. infrastructure scalability
  C. cost minimization
  D. upgrade of technology
  E. transport flexibility
  F. operational continuity
  B. infrastructure scalability
  E. transport flexibility
  F. operational continuity

• Question 50:

  Which option is a benefit of site-to-site VPNs?

  A. less configuration required than a WAN circuit
  B. more secure than a dedicated WAN circuit
  C. less expensive than a dedicated WAN circuit
  D. more reliable than a dedicated WAN circuit
  C. less expensive than a dedicated WAN circuit
