質問 # 60
After an unplanned outage, all VMs were successfully failed over to the recovery site, and users are now accessing workloads from there. The DR dashboard shows the failover is complete and replication from the original primary site has stopped. As part of post-failover cleanup, what is the most appropriate next action to ensure the DR configuration reflects the current production state and is ready for future protection?
正解：B
解説：
Following a successful unplanned failover, the " Recovery Site " has technically become the new " Production Site " . However, the data protection relationship is now one-sided; while the VMs are running at the recovery site, they are likely no longer being replicated anywhere because the original protection policy was designed to move data from the (now failed) primary site to the recovery site.
The most critical post-failover task is to " re-protect " the workloads. This involves updating the Protection Policies in Prism Central to establish a new replication direction, typically from the current active site (the old recovery site) back to the original primary site (once it is restored) or to a third availability zone. Without re- protection, the business is running its production workloads without a safety net, leaving them vulnerable to a second failure. Deleting recovery points (Option A) is dangerous as it removes the only historical data available. Leaving the environment as-is (Option B) ignores the lack of ongoing protection. Initiating an immediate failback (Option D) is often impossible or unwise until the original site is fully stabilized and the data has been synchronized back. Therefore, establishing a new protection stream is the mandatory next step for operational resilience.
質問 # 61
An administrator is tasked with verifying the cluster ' s disaster recovery capability. The administrator needs to validate the capability without impacting the production VMs on the Source cluster and ensure that the destination cluster can bring up all the protected VMs. How can the administrator perform a failover?
正解：B
解説：
Testing is the most vital component of a resilient BCDR strategy, as it proves that recovery objectives (RTO
/RPO) are achievable before a real emergency occurs. The Nutanix " Test Failover " feature is purpose-built for this requirement. Unlike a Planned Failover (which shuts down production) or an Unplanned Failover (which assumes production is dead), a Test Failover performs a non-disruptive validation.
During a Test Failover, the orchestration engine uses the most recent snapshots to power on VMs at the destination cluster. To satisfy the " without impacting production " requirement, the test VMs are typically attached to an " Isolated " or " Test " network segment that has no route to the live production network. This prevents IP address conflicts and service interference while allowing the administrator to log into the recovered VMs and verify that applications start correctly. Simple " Validation " (Option A) only checks the configuration settings and connectivity but does not actually test the power-on sequence or application logic.
By executing a full Test Failover, the organization gains documented proof of its DR readiness, identifying potential issues like missing dependencies or incorrect boot orders without causing any disruption to the users currently accessing the primary site.
質問 # 62
After a storage failover in a synchronous replication environment, users report higher I/O latency and degraded performance compared to pre-failover levels. Cluster health is normal, and replication is functioning correctly. Which post-failover cleanup action could the administrator perform to correct the performance issue?
正解：B
解説：
Synchronous replication environments (like Metro Availability) allow for zero-RPO failover, but the performance of the workload is highly dependent on " Data Locality " . Nutanix architecture is built on the principle that a VM ' s compute (vCPU/RAM) should ideally reside on the same host or cluster that serves its primary storage I/O.
During a storage failover, the " Active " container role may move to the recovery site, but the virtual machines might still be running on the primary site ' s compute nodes. This causes " Remote I/O, " where every read and write must traverse the network link to reach the active storage container at the other site, resulting in the reported higher latency and degraded performance. To resolve this, the administrator must " realign " the compute and storage by performing a vMotion (or live migration) of the VMs to the cluster that is now hosting the active storage role. While the Acropolis Dynamic Scheduler (ADS) (Option D) eventually attempts to rebalance, a manual realignment ensures that performance is restored immediately after the failover stabilization. Reconfiguring schedules (Option C) or retention (Option A) has no impact on real-time I
/O latency, highlighting the critical role of data locality in high-performance BCDR designs.
質問 # 63
During the Recovery Plan configuration, the administrator maps the " Test Network " setting to the " Production Network " VLAN on the Recovery Site. What is the expected outcome when the administrator executes a Test Failover for this plan?
正解：B
解説：
Nutanix Recovery Plans allow for granular control over networking during different failover scenarios. The " Test Network " setting is specifically designed to provide an isolated sandbox for validation. If an administrator incorrectly maps this test network to the actual " Production Network " VLAN at the recovery site, they are effectively bypassing the safety mechanisms intended to isolate the test.
When the Test Failover is executed, the test VMs will boot up on the production VLAN using the exact same IP addresses they have at the source site. If the primary site is still online (which is the case during a test), the existence of two identical VMs with identical IPs on the same logical network will cause immediate IP address conflicts. This can disrupt live production traffic, cause routing instability, and potentially lead to service outages at both sites. The system does not " automatically " isolate traffic (Option B) if the administrator has explicitly directed the test VMs to the production segment. This scenario emphasizes the critical importance of network planning in BCDR: a " Test " network must always be an isolated, non- routable segment to ensure that validation remains non-disruptive as intended.
質問 # 64
Which file system is supported on Linux VMs for Self-Service Restore?
正解：A
解説：
Nutanix Self-Service Restore (SSR) allows end-users to recover files from snapshots without needing assistance from a cluster administrator. This functionality is enabled by Nutanix Guest Tools (NGT), which mounts a snapshot disk to the guest VM. For SSR to function, the Nutanix Guest Agent (NGA) must be able to recognize and mount the file systems present on the snapshots.
For Linux-based virtual machines, Nutanix SSR supports standard, modern journaling file systems. EXT4 is the most widely supported and common file system used across modern Linux distributions like RHEL, CentOS, and Ubuntu, and it is natively supported by the Nutanix SSR agent. While other file systems like XFS or older EXT versions might be supported by the OS itself, EXT4 is the primary validated target for SSR operations. NTFS (Option B) is primarily a Windows file system, though it can be mounted on Linux, it is not the native standard for Linux SSR. Supporting the native file system of the guest OS is critical because it ensures that file permissions and ownership (UID/GID) are preserved during the recovery process. This compatibility allows users to seamlessly mount the snapshot, navigate to the required directory, and restore deleted or corrupted files directly to their production environment.
