• B.The evidence of dropped messages is in `vobd.log`.
• C.The source of excessive logging is `dfwpktlogs.log`.

An Application Developer complains that their VM is intermittently very slow. A VCF Support Engineer uses `esxtop` on the host and observes that while CPU `%RDY` time is low, the host is experiencing memory contention.

• A.`%USED` (CPU Used)
• B.`PSHARE` (Pages Shared)

A Network Administrator is troubleshooting an IPsec VPN tunnel between an NSX Tier-0 Gateway and a remote third-party firewall. The tunnel status is showing as "Down". The administrator has already verified that the pre-shared keys and local/remote IP endpoints match on both sides.
Which of the following are the most common causes for an IPsec VPN tunnel to fail to establish? (Select all that apply.)

• A.The DHCP service on the Tier-0 Gateway is disabled.
• B.The NSX Edge Cluster does not have a license for the VPN service.
• C.A mismatch in the "Tunnel Interface" IP addresses or subnets defined on each side.
• D.A firewall or network ACL between the two VPN endpoints is blocking UDP ports 500 and 4500.
• E.A mismatch in the IKE (Internet Key Exchange) version or encryption/hashing algorithms between the two endpoints.

Question No : 9

An administrator is investigating poor vCenter Server performance. The vSphere Client is slow to load inventory, and tasks take a long time to complete. The administrator has already confirmed that the VCSA virtual machine is not constrained by CPU or memory resources. The next step is to investigate the health of the embedded vCenter Database (VCDB).
What actions should the administrator take to check and potentially improve the performance of the VCDB? (Select all that apply.)

• A.Migrate the vCenter Server appliance to faster storage using Storage vMotion.
• B.Re-register the vCenter Server with SDDC Manager.
• C.Connect to the VCDB and run `VACUUM ANALYZE` to update table statistics and reclaim space.
• D.Check the size of the VCDB tables to identify if any are excessively large, particularly task and event tables.
• E.Use `service-control --stop vmware-vpostgres` to restart the database service.
• F.Increase the amount of RAM allocated to the vSphere Client Server (vsphere-ui) service.

A VCF Support Engineer is troubleshooting a slow virtual machine. The engineer connects to the host running the VM and uses `esxtop` to analyze its performance in real-time.
Review the following `esxtop` output from the CPU view:
ID GID NAME NWLD %USED %RUN %SYS %WAIT %RDY %IDLE %OVRLP %CSTP
271828 271828 DB-Server-01 8 75.21 74.98 0.15 2450.12 15.88 0.00 0.05 0.00
What does the `%RDY` value of 15.88 indicate?

• A.15.88% of the VM's memory is being actively used by the guest operating system.
• B.The VM is ready to execute instructions but is waiting 15.88% of the time for a physical CPU to be scheduled.
• C.The VM's guest OS is waiting 15.88% of the time for storage I/O to complete.
• D.The VM is voluntarily idle 15.88% of the time.
