• Question 142:

  An engineer is designing a data center that uses FCIP. How is QoS configured in this environment?

  A. A separate DSCP value and CoPP must be configured for all FCIP traffic and another for all of the FCIP in the data connection.
  B. A separate DSCP value must be configured for all FCIP VSAN traffic.
  C. A separate DSCP value and priority queuing must be configured for all FCIP traffic.
  D. Two separate DSCP values must be configured, one of all of the FCIP frames in the control TCP connection and another for all of the FCIP frames in the data connection.
  D. Two separate DSCP values must be configured, one of all of the FCIP frames in the control TCP connection and another for all of the FCIP frames in the data connection.

  Explanation Explanation/Reference:Two separate DSCP values must be configured, one for control frames another one for data frames. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/mds9000/sw/5_0/configuration/guides/ipsvc/nxos/ipsvc/cfcip.html

• Question 143:

  What are two reasons to select OTV as the DCI solution to connect multisite topologies? (Choose two.)

  A. It propagates hosts reachability without support of traffic flooding.
  B. Layer 3 failures do not propagate beyond the OTV edge device.
  C. It extends the spanning tree between data centers.
  D. It is an open standard.
  E. It constrains HSRP hello messages to each data center.
  A. It propagates hosts reachability without support of traffic flooding.
  E. It constrains HSRP hello messages to each data center.

  ---

  Explanation Explanation/Reference:OTV introduces the concept of "MAC routing," [...] it is justified by the need to limit flooding of Layer 2 traffic across the transport infrastructure. The last capability introduced by OTV is to filter First Hop Redundancy Protocol (FHRP--HSRP, VRRP, and so on) messages across the logical overlay. https://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Data_Center/DCI/whitepaper/DCI3_OTV_Intro/DCI_1.html

• Question 144:

  An engineer must design a disaster recovery solution for a Cisco ACI Multi-Site network. One requirement is that the applications must have seamless IP addressing across sites. The solution must also be highly resilient and support Layer 2 adjacency.

  Which design meets these requirements?

  A. localized bridge domain, subnet, and EPG stretched Layer 2 broadcast domain
  B. stretched bridge domain with local subnet stretched Layer 2 broadcast domain
  C. localized bridge domain with local subnet localized Layer 2 broadcast flooding
  D. stretched bridge domain, subnet, and EPG localized Layer 2 broadcast flooding
  C. localized bridge domain with local subnet localized Layer 2 broadcast flooding

• Question 145:

  A customer needs a design for a new data center network that meets these requirements:

  1.

  Logically partition the environment into separate security domains.

  2.

  Cut costs related to purchasing additional equipment.

  3.

  Separate routing processes, TCAM, QoS tables, and data planes. Which technology must be used?

  A. VLAN
  B. vPC
  C. VDC
  D. VRF
  C. VDC

  ---

  Explanation Explanation/Reference:for item 3 "Separate routing processes, TCAM, QoS tables, and data planes."

• Question 146:

  A network consultant evaluates the Cisco UCS Fabric Interconnect SAN configuration, which must meet these requirements:

  1.

  All traffic must pass over the upstream device for switching and domain IDs must be preserved in the fabric.

  2.

  Each server should be pinned to one designated upstream interface and for the traffic to pass through the pinned port. Which Fabric Interconnect SAN operational mode meets these requirements?

  A. end host
  B. switch
  C. NPIV
  D. Fibre Channel
  B. switch

• Question 147:

  Refer to the exhibit.

  [Mising Exhibit]

  A Cisco engineer is configuring a data center design scenario with Cisco MDS 90Q0 Series Switches.

  The cut-through routing mode is chosen for impf oved read operation performance. Each (SCSI host requires access lo storage through the IPS module.

  First, the engineer configures the TCP tuning parameters as enabled SACK, the maximum bandwidth of 1 Gbps. buffer size of 4096. keepalive timeout at 1s. and enables Path MTU.

  Then, the engineer must set the OoS of the ISCSI link.

  What is the maximum QoS value that must be set tor the ISCSI session?

  A. 3
  B. 1
  C. 63
  D. 5
  C. 63

• Question 148:

  Refer to the exhibit.

  

  A Cisco engineer is planning a data migration job in heterogeneous SANs where the existing and new storage devices for the migration are already connected to the MDS switches.

  All paths from the SSM to the storage-connected switch are going through the Cisco fabric.

  The setup is with active/active arrays and multiple LUN sets.

  What is the best approach to copy the LUN sets to the new location?

  A. Enable synchronous replication for the new storage array.
  B. Add all paths Fabric-A zones to Fabric-B zones.
  C. Create two data migration jobs, and add two storage pons in each job.
  D. Grant access to all servers to the existing data sets.
  C. Create two data migration jobs, and add two storage pons in each job.

• Question 149:

  A storage engineer requires a solution that achieves multiple paths between a server and storage array. The design must support complete traffic isolation and support a 50% growth in the next year. Which FCoE solution meets these requirements?

  A. single switch with multiple links
  B. at least two VSANs across the fabric
  C. at least two FC zone sets with multiple zones
  D. single VSAN across the fabric
  B. at least two VSANs across the fabric

• Question 150:

  A network consultant reviews the requirements for the Storage Area Network (SAN) design. The proposed solution must offer a very efficient port usage and eliminate the need for a separate physical layer of switches and their associated ISLs. The design is not expected to require future expansion.

  Which SAN topology must be used to meet these requirements?

  A. core-edge
  B. collapsed-core
  C. core-distribution-access
  D. edge-core-edge
  B. collapsed-core
