質問 # 33
Refer to the exhibit. A Cisco engineer is configuring a customer scenario with 2 x MDS 9000 switches 24 x UCS B200M6 blade servers. UCS 64S4 Fabric Interconnect in end-host mode and
3 x UCS 5108 server chassis with 2408 Fabric Extenders. The engineer installs 6 x SQL Server
2019 on all blades and then notices that there are read and write latencies.
What is the best way to balance the utilization across the shared ports?
- A. Change the assigned speed to 8 Gbps Auto.
- B. Disable restrictions on oversubscription ratios
- C. Enable "Only dedicate rate mode
- D. Set 4 Gbps performance buffers
正解:B
解説:
When restrictions on oversubscription ratios are disabled, the bandwidth allocation among the shared ports is proportionate to the configured speed. (If the configured speed is auto, then bandwidth is allocated assuming a speed of 4 Gbps.) For example, if you have three shared ports configured at 1, 2, and 4 Gbps, then the allocated bandwidth ratio is 1:2:4. In Cisco SAN-OS Release 3.0 and later (or when restrictions on oversubscription ratios are enabled), port bandwidths are allocated in equal proportions, regardless of port speed, so, the bandwidth allocation for the same three ports mentioned in the example would be 1:1:1.

質問 # 35
Refer to the exhibit. A Cisco engineer is configuring a next-generation Cisco HyperFlex HX data platform with 2 x Cisco UCS 6248UP fabric interconnects, 8 x Cisco HX-Series HX240c-M4SX servers, plus 8 x Cisco UCS B200-M4 blade servers, Cisco UCS 5108 blade chassis, and Cisco UCS 2204XP fabric extenders. The solution is configured with HX Release 4.5(2a) using VMware ESXi 7.0 U2. After the engineer migrates all customer VMs to the new solution platform, the engineer decides to create HX Native snapshots for all the VMs. The engineer performs the operation and notices that some of the VMs are not creating snapshots. What is the most probable reason that the HX Native snapshots are not created?
- A. The servers have duplicate names
- B. Virtual machines are in suspended state
- C. The source disk is thick provisioned
- D. The node has insufficient datastore space
正解:A
質問 # 36
A network engineer must design a Cisco HyperFlex solution based on these requirements:
* two clusters in the main data center consisting of five HyperFlex nodes
* one edge node tor the remote branch
* cluster nodes that use one rack unit of space
Which two devices should be used in the remote branch cluster for this design? (Choose two.)
- A. Gigabit Ethernet Switch
- B. UCS B200
- C. Fabric Interconnect 6300
- D. HX220c
- E. HX240c
正解:A、D
解説:
HX240 is excluded because it is 2RU, while the requirement is to have one rack unit of space.
UCS B200 and FI 6300 are excluded because the solution is required in a branch.
質問 # 37
Refer to the exhibit.
A cloud service provider deployed three geographically separated Cisco ACI data centers. One of the customers needs to host a clustered application that is spread across the three data centers. The cluster nodes that host the application need a Layer 2 topology to communicate with each other.
Which Cisco ACI topology design meets these requirements?
- A. Multi-Site
- B. Multi-Pod over MP-BGP EVPN
- C. Multi-Cloud
- D. Multi-Pod over OSPF EVPN
正解:B

質問 # 40
A company has several data centers with hundreds of Cisco UCS blade chassis. A network consultant plans to active Cisco Discovery Protocol to the servers to facilitate Layer 1 troubleshooting. For security reasons, the company wants to restrict the servers from sending different MAC addresses to the fabric interconnect after the MAC address from the first packet is learned. Which two policies be modified to support this design? (Choose two.)
- A. Ethernet Adapter
- B. vNIC Policy
- C. vNIC Template Policy
- D. Pin Group Policy
- E. Network Control Policy
正解:C、E

質問 # 43
A company has added a new FCoE storage array to increase the performance of datastore access for end users. This storage array is directly connected to the Cisco Nexus 5672UP switches using four 10G port-channel interfaces. After deployment, the end users fail to access the datastore compared to the older solution. A network engineer verified the port-channel interface and finds that the congestion occurs when PFC frames are generated at the FCoE ingress interface. Which action must be taken to resolve the congestion issue?
- A. Increase the queuing buffer in the port-channel interface connected to the storage array.
- B. Enable the FCoE class in QoS on Cisco Nexus 5672UP switches.
- C. Add an additional FCoE VLAN to the SAN network.
- D. Reserve bandwidth for FCoE VLAN on the port-channel interface connected with storage.
正解:B
