Multiple I/O modules must be installed in Dell Unity XT 680 storage.
Which module must be installed in slot 0?
- A. 4-Port 10 Gbps Ethernet
- B. 12 Gb/s SAS back-end
- C. 4-Port 16 Gb Fibre Channel
- D. 4-Port 25 Gbps Ethernet

The Unity XT 680 system supports four types of I/O modules: 12 Gb/s SAS back-end, 4-Port 16 Gb Fibre Channel, 4-Port 25 Gbps Ethernet, and 4-Port 10 Gbps Ethernet. The 12 Gb/s SAS back-end module provides connectivity to the disk drives and expansion enclosures, while the other three types of modules provide network connectivity to the hosts and clients. The Unity XT 680 system has six I/O module slots, three for each SP. The 12 Gb/s SAS back-end module must be installed in slot 0 of each SP, and the other modules can be installed in slots 1 and 2 of each SP. Therefore, the correct answer is D. 12 Gb/s SAS back-end.

NEW QUESTION # 32
A storage administrator must configure replication from a production Dell Unity XT 680F to an offsite DR Dell Unity XT 480. Block resources must be replicated without data loss if the production site becomes unavailable. File resources can be replicated with an acceptable amount of data difference on the destination.
What replication configuration meets the requirements?
- A. Configure the replication connection mode to Both.
- B. Set Unisphere resource filtering to All.
- C. Configure the replication interfaces on the 4-port mezzanine card.
- D. Set an RPO of 0 on the synchronous replication sessions.
Answer: A
Explanation:
To meet the requirements, the replication connection mode must be set to Both, which allows both synchronous and asynchronous replication sessions to be configured on the same connection. This way, block resources can use synchronous replication, which ensures zero data loss, and file resources can use asynchronous replication, which allows some data difference on the destination. Setting Unisphere resource filtering to All is not necessary, as it only affects the display of resources in the Unisphere GUI. Setting an RPO of 0 on the synchronous replication sessions is redundant, as synchronous replication always has an RPO of 0. Configuring the replication interfaces on the 4-port mezzanine card is not relevant, as it only affects the performance and availability of the replication network.

NEW QUESTION # 39
A system administrator deployed a UnityVSA to their vSphere environment. They did not add the management IP to the UnityVSA during the installation.
Which command must be used to apply the management IP from the vSphere UnityVSA console?
- A. svc_ipmi
- B. svc_inject
- C. svc_initial_config
- D. svc_change_hw_config
Answer: C
Explanation:
To apply the management IP from the vSphere UnityVSA console, the system administrator must use the svc_initial_config command. This command allows the user to configure the initial network settings for the UnityVSA, such as the management IP address, subnet mask, gateway, and DNS servers. The svc_ipmi command is used to configure the IPMI settings for the UnityVSA, such as the IPMI IP address, username, and password. The svc_change_hw_config command is used to change the hardware configuration of the UnityVSA, such as the number of CPU cores, memory size, and disk size. The svc_inject command is used to inject faults into the UnityVSA for testing purposes.

NEW QUESTION # 47
Which two actions are recommended according to best practices when connecting iSCSI host to a Dell Unity XT system? (Choose two.)
- A. Use standard NIC for iSCSI.
- B. Use private network for iSCSI interfaces.
- C. Manually register host on storage array.
- D. Interfaces should be on separate subnets.
Answer: B,D
Explanation:
Two actions that are recommended according to best practices when connecting iSCSI host to a Dell Unity XT system are to ensure that the interfaces are on separate subnets and to use a private network for iSCSI interfaces. These actions can improve the performance, security, and availability of the iSCSI network.
Having interfaces on separate subnets can prevent broadcast storms, reduce network congestion, and enable multipathing. Using a private network for iSCSI interfaces can isolate the iSCSI traffic from other network traffic, reduce the risk of interference or attacks, and simplify the network configuration. Manually registering host on storage array and using standard NIC for iSCSI are not recommended actions, as they can introduce errors, inefficiencies, and limitations.

NEW QUESTION # 48
On a Dell Unity XT file system asynchronous replication session, how many system Snapshots are required to support replication?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: D
Explanation:
Explanation
On a Dell Unity XT file system asynchronous replication session, four system Snapshots are required to support replication. Two system Snapshots are created on the source file system, and two system Snapshots are created on the destination file system. The source system Snapshots are used to track the changes that need to be replicated, and the destination system Snapshots are used to apply the changes and maintain a consistent point-in-time copy of the source data. The system Snapshots are automatically created and managed by the replication engine and are not visible to the user.
