VMware 6V0-22.2/VMware Avi Load Balancer
30.x Administrator practice EXAM.
1. Which three components make up the VMware Avi Load
Balancer platform?
✅ A. Controller, Service Engine, and Cluster (or Controller
cluster)
Rationale: Avi uses a three-plane architecture: Management
(Controller), Data (Service Engines), and Control (distributed). The
Controller cluster provides management and analytics; Service
Engines (SEs) handle data plane traffic .
2. What is the minimum number of Controller nodes
recommended for a production environment?
✅ C. 3
Rationale: A three-node Controller cluster provides high
availability for the management plane. A single-node
,Page 2 of 99
deployment lacks fault tolerance, and two nodes cannot form a
proper quorum.
3. A vSphere administrator deploys a new Avi Controller OVA
but cannot log in with default credentials. What is the most
likely reason?
✅ D. The Controller requires first-time setup via the web
interface to create an admin user
Rationale: Unlike many appliances, Avi Controller OVA does not
ship with a default password. The first boot presents a setup
wizard in the web UI to configure the admin user and network
settings .
4. Which orchestration mode must be selected for a vCenter
cloud to allow the Avi Controller to automatically deploy and
manage Service Engines?
✅ B. Write Access
Rationale: Write Access mode permits the Controller to create,
,Page 3 of 99
modify, and delete Service Engine VMs in vCenter. Read Access
allows discovery only; No Orchestrator requires manual SE
deployment .
5. When configuring a vCenter cloud, which credential is
required for Avi Controller to authenticate with vCenter?
✅ C. vCenter username and password with appropriate
privileges
Rationale: The Controller needs vCenter credentials to orchestrate
SE VMs. These credentials are stored encrypted and require
permissions such as Create VM, Delete VM, and Network
configuration .
6. What is the default behavior of Service Engine high
availability for a Virtual Service?
✅ C. Active/Standby with N+M model
Rationale: By default, Virtual Services are placed on SEs with an
active-standby model. The N+M HA model allows designating
, Page 4 of 99
backup SEs for failover, configurable per Virtual Service or SE
Group .
7. Which statement about Avi Controller clustering is true?
✅ B. The cluster uses a leader-follower quorum model
Rationale: Avi Controller uses a three-node cluster with leader-
follower architecture. The leader handles write operations;
followers are promoted automatically if the leader fails.
8. A DevOps team reports high CPU ready time on the Service
Engine VM in vCenter after enabling a WAF policy. What does
this indicate?
✅ A. The Service Engine is undersized for the inspection
workload
Rationale: Increased CPU ready time indicates the ESXi host is
contending for CPU resources. WAF inspection is CPU-intensive;
the SE VM likely needs more vCPUs or the host is
oversubscribed .
