An administrator is responsible for the following Nutanix Enterprise Cloud environment:
• A central datacenter with a 20-node cluster with 1.5PB of storage
• Five remote sites each with a 4-node cluster with 200TB storage
The remote sites are connected to the datacenter via 1GB links with an average latency of 6 ms RTT.
What is the minimum RPO the administrator can achieve for this environment?
- A . 0 minutes
- B . 15 minutes
- C . 1 hour
- D . 6 hours

What should an administrator do to resolve this issue?
- A . Increase SSD capacity
- B . Increase the OPLOG
- C . Increase the write cache
- D . Use HDDs with higher RPM
An administrator is notified that a bare metal database server is down. This database server is being served storage using a Nutanix Volume Group. Upon investigating, the administrator finds that the disks in the database server that map to the vDisks in the volume group have gone offline.

- B . Port 9443 is blocked in the server firewall.
- C . Port 3260 has been blocked in the server firewall.
- D . A CVM serving the Volume Group has gone offline.
An administrator has a VM that consumes large amounts of storage and has the following characteristics:
• Create large / sequential writes
• Data must be kept for years
• Data is normally only accessed at the end of the year to run report.
The administrator decides to use Erasure Coding to save space.
Which feature should the administrator utilize to save space for this VM?
- A . Inline Compression
- B . Flash Mode
- C . Cache Dedup

- A . As a single VM on the Nutanix cluster
- B . On hardware external to the Nutanix duster
- C . As a clustered VM setup on the Nutanix cluster
- D . As a single VM deployed on the host that contains the Prism leader CVM
An administrator has two clusters: Site A and Site B.
Async DR is configured between the clusters as follows:
• Site A is the Primary Site
• Site B is the Secondary inactive Site, no VMs running
• Site A is fully in Production
• Site B used as Backup/Disaster Recovery
The customer wants to perform a planned failover between the sites.
How should the administrator accomplish this?
- A . Click Activate on the Secondary site within the Data Protection Dashboard
- B . Click Activate on the Secondary site and run deactive NCLI command on Primary site
- C . Choose Migrate on the Secondary site within the Data Protection Dashboard
- D . Choose Migrate on the Primary site within the Data Protection Dashboard
A customer has Metro Availability configured in Automatic Resume Mode between Site A and Site B.
What happens to VMs if Primary Site A has full network failure?
- A . Automatic protection domain promotion in Site
- B . VMs automatically restart in Site B
- C . VMs continue to run on Site A following an automatic disable of protection domains.
- D . An administrator must unwitness in Site B and promote protection domains in Site B for VMs to restart
- E . An administrator must promote protection domains in Site B for VMs to restart.
Refer to the exhibit.
What is the purpose of eth2 on the CVMs?
- A . RDMA Network Segmentation
- B . iSCSI connectivity
- C . Remote site connectivity
- D . Network Segmentation
A company needs to replicate their VMs to a remote site and must have an RPO of less than 1 hour. When creating a protection domain, what should an administrator do to meet this requirement?
- A . Enable Async Replication with an RPO of 60 minutes
- B . Enable Near-Sync Replication with an RPO of 15 minutes
- C . Enable Entity Sync on the designated VMs
- D . Enable Availability Zones and send the VM to multiple targets
An alert about RX errors on eth2 on a node is reported in the cluster. The administrator logs in to the CVM in question, checks the ping_* files in the data/logs/syststats folder, and notices intermittent ping loss.
The node in question has the following network configuration:
Which action should be used to troubleshoot without disrupting the VMs running on this node?
- A . Replace the cable from eth2 to the switch
- B . Remove eth3 from br0-up and monitor for new alerts
- C . Check the port on the switch side for any errors
- D . Enable balance-s1b on br0-up and monitor if a problem persists
