Which type of BIOC rule is currently available in Cortex XDR?
- A . Threat Actor
- B . Discovery
- C . Network
- D . Dropper
B
Explanation:
The type of BIOC rule that is currently available in Cortex XDR is Discovery. A Discovery BIOC rule is a rule that detects suspicious or malicious behavior on endpoints based on the Cortex XDR data. A Discovery BIOC rule can use various event types, such as file, injection, load image, network, process, registry, or user, to define the criteria for the rule. A Discovery BIOC rule can also use operators, functions, and variables to create complex logic and conditions for the rule. A Discovery BIOC rule can generate alerts when the rule is triggered, and these alerts can be grouped into incidents for further investigation and response12.
Let’s briefly discuss the other options to provide a comprehensive explanation:
A DevOps Engineer is evaluating the VM Service (Virtual Machine Service) included with vSphere with Tanzu.
What is the primary architectural purpose of this service?
- A . To run containerized applications inside a specialized Virtual Machine without a Kubernetes control plane.
- B . To replace vCenter Server as the primary management interface for all vSphere Virtual Machines.
- C . To convert existing Virtual Machines into vSphere Pods automatically.
- D . To allow developers to provision and manage Virtual Machines using Kubernetes-native APIs (kubectl) alongside containerized workloads.
A Platform Engineer needs to configure a vSphere Namespace to allow a specific Active Directory group, [email protected], to have full administrative access to the Kubernetes namespace, including the ability to create and delete TKG clusters. The solution must follow the principle of least privilege within vSphere.
Which configuration steps in the vSphere Client will achieve this? (Select all that apply.)
- A . Assign the NSX Administrator role to [email protected] in NSX Manager.
- B . In the Namespace permissions, add [email protected] with the CanEdit role.
- C . Ensure the Identity Source corp.local is configured in vCenter Single Sign-On.
- D . In the Namespace permissions, add [email protected] with the Owner role.
- E . Assign the Administrator role to [email protected] at the vCenter Server Global Permissions level.
10:08 AM – Cluster Autoscaler adds 1 node.
This cycle repeats, causing instability.
What is the most effective configuration change to stabilize this cluster? (Select all that apply.)
- A . Increase the HPA sync period or adjust HPA metrics to be less sensitive to short bursts.
- B . Increase the scale-down-unneeded-time (or scale-down-delay) in the Autoscaler profile to a value longer than the typical traffic fluctuation cycle (e.g., 30 minutes).
- C . Enable optimize-allocation mode on the Supervisor.
- D . Disable the Cluster Autoscaler and manually size the cluster for peak load.
- E . Decrease the max-size of the node pool to prevent it from growing.
A Cloud Administrator needs to prepare a VKS environment for a "Private Cloud" deployment where all Kubernetes nodes must pull their system images (e.g., kube-proxy, coredns, antrea) from a central Harbor Registry instead of the internet.
Review the configuration snippet for the TkgServiceConfiguration (the global TKG configuration object):
apiVersion: run.tanzu.vmware.com/v1alpha1
kind: TkgServiceConfiguration
metadata:
name: tkg-service-configuration
spec:
defaultCNI: antrea
…
trust:
additionalTrustedCAs:
– name:
harbor-ca-cert
data: LS0tLS1… (Base64)
imageRepository:
host:
harbor.corp.local
caCertificate: LS0tLS1…
(Base64)
What is the effect of configuring the imageRepository field in this spec? (Select all that apply.)
- A . It forces all user workloads (Pods) to use this registry by default.
- B . It overrides the default upstream VMware registry location for all newly created TKG clusters.
- C . It configures the TKG worker nodes to trust the CA certificate of the Harbor registry.
- D . It instructs the Supervisor to rewrite the image manifests for system components (like CoreDNS) to point to harbor.corp.local instead of projects.registry.vmware.com.
- E . It automatically copies/replicates the images from VMware Public Registry to harbor.corp.local.
A Platform Engineer is designing a Blue/Green Deployment model for a critical application using Contour Ingress Controller.
Goal:
・ v1 of the app is live.
・ v2 is deployed but receives no traffic.
・ The engineer wants to shift 10% of the traffic to v2 for testing (Canary) before a full switch.
Which Contour Custom Resource Definition (CRD) should be used instead of the standard Kubernetes Ingress object to achieve this weighted traffic splitting?
- A . IngressRoute
- B . NetworkPolicy
- C . HTTPProxy
- D . ServiceEntry
- E . VirtualService
A VI Administrator is optimizing the resource allocation for a vSphere Namespace named prod-analytics running critical stateful workloads. The goal is to ensure that the memory for these workloads is fully reserved on the ESXi hosts to prevent contention, while allowing CPU to burst.
Review the available configuration options in the Namespace "Resource Limits" section:
[CPU]
Limit: [Enter Value] MHz
Reservation: [Enter Value] MHz
[Memory]
Limit: [Enter Value] MB
Reservation: [Enter Value] MB
Which specific configuration actions should the administrator perform? (Select all that apply.)
- A . Set the CPU Reservation to equal the CPU Limit.
- B . Configure the Storage Policy to thick-provisioned.
- C . Set the Memory Reservation to equal the Memory Limit (e.g., 64000 MB).
- D . Leave the Memory Reservation at 0 (default).
- E . Set the Memory Limit to the desired capacity (e.g., 64000 MB).
A Cloud Administrator needs to resolve a "Condition: False" error on a Supervisor Cluster related to network connectivity. The Supervisor cannot reach the external image registry to pull system images.
Review the following log snippet from the Supervisor’s WCP service:
E1121 10:05:01.442 controller.go:120] Failed to pull image ‘projects.registry.vmware.com/tkg/tanzu-kubernetes-grid-service-v2.0.0’:
rpc error: code = Unknown desc = Error response from daemon: Get https://projects.registry.vmware.com/v2/: dial tcp 10.128.0.45:443: i/o timeout
The administrator verifies that the firewall rules allow traffic from the Supervisor Management Network IP range to the internet.
What configuration on the Supervisor is most likely missing or incorrect, preventing this connection? (Select all that apply.)
- A . The Proxy Settings (HTTP/HTTPS Proxy) have not been configured or are incorrect on the Supervisor, preventing it from routing internet-bound traffic through the corporate gateway.
- B . The Egress CIDR for the Namespaces is exhausted.
- C . The Supervisor’s Management Network Gateway is configured incorrectly.
- D . The DNS Server settings on the Supervisor are incorrect, causing name resolution to fail.
- E . The Image Registry Service has not been enabled on the Supervisor.
What is the standard procedure for upgrading the vSphere Supervisor Cluster to a newer version?
- A . The upgrade is performed exclusively through the NSX Manager interface, as it controls the Supervisor networking.
- B . The administrator must download an ISO image, mount it to each Control Plane VM, and run an upgrade script manually.
- C . The upgrade requires a complete re-installation of the Supervisor Cluster; workload data must be backed up and restored manually.
- D . The upgrade is initiated from the vSphere Client by selecting the Supervisor Cluster and choosing a target version, which triggers a rolling update of the Control Plane VMs and the Spherelet agents on the ESXi hosts.
A Cloud Administrator is optimizing the Supervisor configuration. They initially deployed the Supervisor with the NSX Advanced Load Balancer (Avi). However, users are reporting certificate warning errors when accessing the Supervisor Control Plane API endpoint.
Review the current status:
Status: Running
Config Status: Certificate Untrusted
[Certificate Details]
Subject: CN=192.168.10.50
Issuer: CN=192.168.10.50
Type: Self-signed
To resolve this and ensure compliance, the administrator needs to replace the machine SSL certificate.
Which specific actions are part of the correct procedure to replace the Supervisor certificate? (Choose 2.)
- A . Re-run the "Enable Workload Management" wizard to inject the new certificate.
- B . Upload the signed certificate chain and private key to the Supervisor configuration in the vSphere Client.
- C . Replace the machine SSL certificate on the vCenter Server system; the Supervisor inherits this trust automatically.
- D . Replace the certificate directly inside the Supervisor Control Plane VM using SSH and openssl commands.
- E . Generate a new CSR (Certificate Signing Request) from the vSphere Client under "Workload Management" > "Supervisor" > "Configure" > "Certificates".
