A Cisco engineer is analyzing a customer environment where dozens of VMs are running on a physical server and UCS chassis are cascaded The setup uses two ISLs in a port channel to the SAN switch (per fabric) The oversubscription from VM to physical SAN port is often 20 (VMs/host) x 72 (9 UCS chassis cascaded = 72 hosts): 2 (ISLs from fabric interconnect to SAN switch port on the NPV core (NPIV enabled switch) This results to 20 x 72 2 per single ISL = 720 VMs per ISL
20 (VMs per host) x 8 (hosts per chassis) x 9 (chassis per port channel to SAN switch) / 2 (ISLs per port channel) = 20 x 8 x 9 / 2 = 720 VMs per SAN F-port What is the best way to resolve possible IOPS bottleneck?
A midsize corporation with significant data-storage requirements is planning to deploy RFC 3720-based technology in its data center to provide efficient and reliable block-level storage access to servers The corporation requires a robust solution with optimal performance, load-balancing, and fault tolerance. The solution must use multiple network paths to optimize bandwidth usage and provide redundancy LACP has already been enabled on the data-center switches Which two actions must be taken to accomplish the goal? (Choose two.)
Implement VLAN tagging in accordance with the IEEE 802.10 standard to segregate iSCSI traffic from other data-center traffic
A network engineer designs a virtual network in a Cisco UCS Manager. The traffic must be explicitly forwarded from the vNIC on the server to a specific uplink Ethernet port on the Cisco fabric interconnect. Also, the server vNIC must use the same uplink Ethernet port after reboot. Finally, the design requires a OoS policy for remote direct memory access over converged Ethernet (RoCE v2). Which set of design features meets these requirements?
Refer to the 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?
What are two reasons to select OTV as the DCI solution to connect multisite topologies? (Choose two.)
An engineer must secure the payload traversing across the DCI. The solution must support confidentially and integrity and it must be open standard. The solution must encrypt Ethernet frames regardless of the upper layer protocol used. Which technology must be used to support these requirements?
Refer to the exhibit.
A Cisco UCS chassis that has two IOMs is discovered. The chassis discovery policy creates a fabric port channel. What is the result of this policy?
An engineer must design a Cisco UCS environment that will connection to a storage area network. The solution must include support for these conditions:
• connectivity to the existing 10 Gigabit Ethernet network
• booting the server infrastructure from the network
• integration with the existing Fibre Channel storage arrays
• lossless data transfer
Which solution should be used to meet these requirements?
Refer to the exhibit. An engineer builds a data center network design using EVPN technology. Within the design, the fabric acts as a gateway. Traffic from host X to host Y must pass through the Cisco ASA firewall for deep packet inspection and increased security. Which firewall deployment must the engineer choose to accomplish this goal?
A Cisco engineer is preparing a service profile template for a design, which consists of 20 x UCS B200M6 blade servers 2 x UCS 6454 Fabric Interconnect in End Host Mode, and 3 x UCS 5108 server chassis with 2408 Fabric Extenders The blade servers are equipped with VIC 1480 adapters The engineer does not configure a vNIC/vHBA placement policy in the service profile and the vNICs and vHBAs are assigned to the vCon in a particular order What is the mapping scheme in which Cisco UCS assigns the vCons based on the type of server and the selected virtual slot?
