Answer

By rebooting the top-of-rack physical network switches when BGP convergence fails.

Question 7

An infrastructure architect is designing a vSphere Foundation 9.0 cluster and needs to implement SR-IOV (Single Root I/O Virtualization) for high-throughput trading virtual machines. What is a key architectural trade-off when implementing SR-IOV virtual functions (VFs)?

Accepted Answer

Certain vSphere features such as live vMotion, fault tolerance, and snapshots may be limited or require specific hardware vendor support due to direct hardware binding.. SR-IOV bypasses the hypervisor network stack to deliver near-native hardware performance, but doing so means certain hypervisor-based features like vMotion, live snapshots, and DRS migration compatibility may be restricted or require specific hardware support.

Answer

SR-IOV requires all virtual machines to run exclusively on Linux kernel version 2.4.

Answer

SR-IOV doubles the CPU utilization of the ESXi host for packet encapsulation.

Answer

SR-IOV restricts virtual disk sizes to a maximum of 2 gigabytes.

Question 8

Accepted Answer

Native multipathing support built into the NFS 4.1 client for load balancing and path failover.. NFS 4.1 adds native multipathing support (SESSION trunking/multipathing) directly within the ESXi client, whereas NFSv3 relied on multiple mount points or third-party workarounds for multipathing.

Answer

Mandatory integration with Fibre Channel zoning tables.

Answer

Automatic conversion of file shares into block-level VMFS datastores at the hypervisor layer.

Answer

Elimination of IP address requirements by using MAC-layer bridging.

Question 9

An infrastructure architect is designing a vSphere Foundation 9.0 environment with strict compliance requirements. They need to ensure that all API traffic and administrative sessions to vCenter Server are audited and forwarded to a centralized SIEM (Security Information and Event Management) system. Which architectural feature should be configured?

Accepted Answer

Configure vCenter Server syslog forwarding to stream audit and access logs securely to the enterprise SIEM collector.. vCenter Server supports forwarding audit logs and syslog events directly to external syslog collectors using secure TLS or UDP/TCP transport.

Answer

Enable Fault Tolerance replication on the vCenter database tables.

Answer

Configure Storage DRS to clone audit log files every hour.

Answer

Install an unencrypted FTP server on every ESXi host to dump core dumps.

Question 10

An infrastructure architect is designing a vSphere Foundation 9.0 environment where virtual machines running cryptographic workloads require hardware random number generator access. Which design approach satisfies this requirement?

Accepted Answer

Configure virtual machines with a virtual hardware random number generator (vHRNG) device backed by the host hardware entropy source.. Providing virtual machines with access to a virtual hardware random number generator (vHRNG) allows guest operating systems to draw entropy from the ESXi host's hardware RNG or TPM.
