質問 # 69
What influences the number of ISLs that are required between Cisco MDS Series switches?
- A. N Port virtualization
- B. end-to-end oversubscription ratio
- C. type of storage
- D. FCoE protocol
正解：B
解説：
The number of ISLs required between Cisco MDS switches will depend on the desired end-to-end oversubscription ratio. The storage port oversubscription ratio from a single storage port to multiple servers can be used to help determine the number of ISLs needed for each edge-to-core connection.

質問 # 71
An engineer is experiencing performance issues on a cisco UCS blade server. The B-series blade server contains four CPUs, most of which are idle. The engineer notices that the CPU is suffering from too many requests sent by the NIC. Additionally, the number of queues appears to be insufficient and only a single CPU is processing the network traffic. Which policy must be used to alleviate these issues?
- A. Ethernet adapter
- B. Dynamic vNIC connection
- C. LAN connectivity
- D. vNIC placement
正解：A
解説：
Reference:
Ethernet adapter policy is the only policy that is having configuration that is related to CPU.

質問 # 73
An engineer is designing a data center that uses FCIP. How is QoS configured in this environment?
- A. 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.
- B. A separate DSCP value and CoPP must be configured for all FCIP traffic and another for all of the FCIP in the data connection.
- C. A separate DSCP value and priority queuing must be configured for all FCIP traffic.
- D. A separate DSCP value must be configured for all FCIP VSAN traffic.
正解：A
質問 # 74
Refer to the exhibit.
A default route must be advertised into the VXLAN fabric for internet access. The engineer must use a static route because the edge firewall does not support any dynamic routing protocol. Which two features must the engineer use to allow learning and withdrawing of the default route without any manual intervention?
(Choose two)
- A. IP forwarding
- B. Network Address Translation
- C. policy-based routing
- D. HMM tracking
- E. anycast gateway
正解：C、E
質問 # 75
Which mode must be enabled on a Cisco UCS Fabric Interconnect to connect directly to a storage array?
- A. NPV mode
- B. FC switching mode
- C. NPIV mode
- D. FC end-host mode
正解：B
解説：
Switch mode is the traditional Fibre Channel switching mode. Switch mode allows the fabric interconnect to connect directly to a storage device. Enabling Fibre Channel switch mode is useful in POD models where there is no SAN (for example, a single Cisco UCS system connected directly to storage), or where a SAN exists (with an upstream MDS).
質問 # 76
An engineer develops a framework for automatic repetitive tasks needed to manage a Cisco Nexus 9000 Series Switch. The engineer plans to use a programmatic interface and must keep these considerations in mind.
* The customer's environment requires the script to authenticate before executing further actions.
* The customer's security requirements mandate the use of HTTP transport.
* The automation team is familiar with parsing messages encoded in XML or JSON format.
Which solution meets these requirements?
- A. NX-API
- B. SNMPv3
- C. gRPC
- D. RESTCONF
正解：A
質問 # 77
Refer to the exhibit Due to power limitations at the customer data center, the engineering team must decommission one of the modular switches in the new design the customer must ensure that the OSPF process is fully protected on the remaining switch and minimize OSPF flapping in case of any module failure. Which solution fulfills the requirements for the new design?
- A. LSA aging timer change
- B. OSPF area separation
- C. graceful restart
- D. routing summarization
正解：C
質問 # 78
Which two methods mitigate congestion in a SAN network? (Choose two.)
- A. Configure the port channel to enable individual buffer-to-buffer credits.
- B. Configure ER_RDY to allow splitting of each ISL between switches into separate virtual links.
- C. Use the port-monitor command to detect slow drain devices.
- D. Configure the port monitor to allow categorization of a specific device as slow.
- E. Configure the flow control for the FC to use R_RDY.
正解：C、D

質問 # 79
An engineer is installing a Cisco Nexus 7000 Series Switch with F2-Series I/O Module. The company's strict security policy requires that the port be in-band. The engineer must also keep these considerations in mind:
* The customer's security requirements mandate the use of a secure management mechanism that supports authentication and encryption.
* The port should support management over IP.
Which port type must be used to meet these requirements?
- A. management port
- B. console port
- C. Ethernet port
- D. connectivity management port
正解：A
質問 # 80
Refer to the exhibit.
What must be the default gateway of the servers in EPG Web?
- A. subnet address of L3Out
- B. NAT appliance
- C. subnet address of BD2
- D. subnet address of BD1
正解：B
質問 # 81
An engineer is configuring Fibre Channel policies in a service profile template. The requirement is to set the default vHBA behavior policy as part of the deployment. The Cisco UCS Manager must also create the required vHBA type based on the adapter installed on the server and associated with the service profile. Which action meets the requirements?
- A. Enable the HW Inherit settings.
- B. Set the dynamic-uuid identity.
- C. Apply the Linux settings profile.
- D. Configure the Windows settings profile.
正解：A
質問 # 82

質問 # 83
An end user is experiencing network latency when accessing a database in a disaster recovery site. The monitoring team concluded that the database was writing simultaneously to the storage arrays on the primary and disaster recovery sites.
Which design resolves this issue?
- A. synchronous replication between data centers
- B. asynchronous replication between data centers
- C. FCIP tunneling between data center
- D. FCoE tunnel between data center
正解：B
質問 # 84
An engineer must design a Cisco UCS environment for a customer The design requires the most efficient use of available bandwidth with active-active uplinks The upstream Cisco Nexus 9000 Series Switch must automatically initiate the port-channel connectivity to the fabric interconnects Which configuration must the engineer choose to meet these requirements?
- A. * fabric interconnects in Ethernet end-host mode
* LACP port-channel from fabric interconnects and Cisco Nexus 9000 switches - B. * fabric interconnects in Ethernet switching mode
* LACP port-channel from fabric interconnects and Cisco Nexus 9000 switches - C. * fabric interconnects in Ethernet end-host mode
* static port-channel from fabric interconnects and Cisco Nexus 9000 switches - D. * fabric interconnects in Ethernet switching mode
* static port-channel from fabric interconnects and Cisco Nexus 9000 switches
正解：A
