A disk failure has occurred in a vSAN cluster.
What four steps should be taken to recover from this disk failure? (Choose four.)
- A . Use the vSohere Client to check the vSAN Health Service
- B . Disable disk group encryption
- C . Rebuild the affected disk group
- D . Perform a full resync of the vSAN objects
- E . Replace the failed disk with a new one
- F . Ensure the new disk is claimed by the vSAN cluster
A, C, E, F
Explanation:
Checking the vSAN Health Service in the vSphere Client is the first step in diagnosing the issue and verifying the status of the vSAN components after the disk failure.
Rebuilding the affected disk group is necessary to ensure that data is re-optimized and replicated in accordance with the vSAN policy.
Replacing the failed disk with a new one ensures that the storage capacity is restored.
Ensuring that the new disk is claimed by the vSAN cluster is important to ensure that it is recognized and integrated into the vSAN disk group.
Which log files or logging methods can help diagnose ESXi host and VM issues effectively?
- A . hostd.log on each ESXi host
- B . vpxd.log on the vCenter Server
- C . Putting logs on ephemeral port bindings
- D . Forwarding to vRealize Log Insight
A, B, D
Explanation:
hostd.log (A) and vpxd.log (B) are key logs for ESXi and vCenter, and forwarding logs to vRealize Log Insight (D) centralizes analysis. Ephemeral port bindings (C) are unrelated to logging practices.
When designing a network for a VMware vSphere environment, which of the following should be considered to ensure optimal performance and security?
- A . Using VLAN trunking for isolating traffic
- B . Implementing ephemeral port groups for production VMs
- C . Enabling NIC teaming with appropriate load-balancing policies
- D . Reserving one NIC solely for management traffic
A, C, D
Explanation:
VLAN trunking (A) segments traffic securely. NIC teaming (C) improves network throughput and redundancy, and dedicating a NIC to management (D) protects critical functions. Ephemeral port groups (B) are typically used temporarily or for special cases, not standard production use.
Which tasks can vSphere Lifecycle Manager (vLCM) accomplish in a VMware environment?
- A . Automated ESXi host patching and firmware updates
- B . Provisioning new VMs from templates
- C . Deploying vendor-specific hardware drivers across multiple hosts
- D . Configuring vSAN disk groups automatically
A, C, D
Explanation:
vLCM automates ESXi patching, firmware driver deployment (A, C), and can configure vSAN disk group versions (D). VM provisioning (B) is performed via vCenter or Content Library, not specifically vLCM.
An administrator is tasked with deploying a new VMware Cloud Foundation (VCF) instance.
The management domain is designed to be created with three virtual distributed switches (VDS) configured as follows:
– VDS1 – used for management and vMotion traffic
– VDS2 – used for vSAN traffic
– VDS3 – used for NSX Overlay traffic
What action would the administrator take to deploy the designed configuration?
- A . A JSON file must be prepared with the defined configuration and used to run the bring-up process.
- B . vSphere Distributed Switch Profile 2 must be selected in the VCF Deployment parameter workbook.
- C . The design must be changed to ensure vSAN and NSX overlay traffic are on the same VDS.
- D . The ESXi hosts have to be configured with twelve physical NICs to ensure redundancy.
Which security feature in ESXi ensures that only signed and trusted code can run during the host boot process?
- A . Lockdown Mode
- B . Secure Boot
- C . TPM 2.0 Integration
- D . vSphere Encryption
B
Explanation:
Secure Boot uses digital signatures to verify the integrity of the ESXi boot loader and kernel modules. Lockdown Mode restricts remote access, TPM integration stores cryptographic keys, and vSphere Encryption secures VM data at rest, not the boot process itself.
A newly added ESXi host is not able to communicate with the vCenter Server.
What three steps should an administrator take to diagnose and resolve this issue? (Choose three.)
- A . Verify the network configuration on the ESXi host
- B . Check the license on the ESXi host
- C . Use the vSphere Client to review the host’s network settings
- D . Ensure that the management network is correctly configured and reachable
- E . Restart the manaqement aqents on the ESXi host
A, D, E
Explanation:
Verifying the network configuration on the ESXi host ensures that the host is correctly configured for network communication with the vCenter Server.
The management network must be properly configured and reachable from the ESXi host to communicate with the vCenter Server.
Restarting the management agents on the ESXi host can resolve issues related to communication between the ESXi host and vCenter Server, as sometimes the agents might become unresponsive.
When considering standardization in VMware environments, which of the following are aligned with industry or regulatory best practices?
- A . Hardening guides that align with NIST standards
- B . Role-based access control following ISO 27001 principles
- C . CO2 emission compliance
- D . Regular audits and patching guided by ITIL processes
A, B, D
Explanation:
NIST-based hardening guides, ISO 27001-aligned RBAC, and ITIL-driven audits and patching all intersect with VMware security and operational best practices. CO2 emissions (C) are environmental considerations, not typically covered under VMware’s security/operational standards.
A vCenter Server is showing high CPU usage due to large inventory and frequent tasks.
Which approach can alleviate performance issues?
- A . Disable DRS and HA on all clusters
- B . Increase vCenter resource allocation or place it on a faster datastore
- C . Remove all resource pools from the environment
- D . Create additional vCenter Servers with Enhanced Linked Mode
B
Explanation:
vCenter might need additional CPU, memory, or faster storage. Disabling DRS/HA (A) or removing resource pools (C) undermines cluster functionality. While multiple vCenters (D) could help in extremely large environments, the more direct approach is usually allocating more resources or moving to faster storage.
Which vSphere feature helps you reclaim idle or unused disk space within guest operating systems by coordinating the hypervisor and OS?
- A . Ballooning
- B . Transparent Page Sharing
- C . Storage I/O Control
- D . UNMAP / Guest OS trim
D
Explanation:
The UNMAP feature (sometimes referred to as trim for SSDs) reclaims blocks that guest OSes free, updating the storage system so that this space can be reused.
