VMware Avi Load Balancer 30.x Administrator - 6V0-22.25 Exam Questions [2026]

QUESTION NO: 1
A Virtual Service is scaled out across three Service Engines (an Active/Active configuration). One of the three Service Engines experiences a sudden failure (e.g., the ESXi host it is running on crashes). What is the expected impact on client traffic?

A. The Avi Controller will immediately migrate the Virtual Service to a new standby Service Engine. B. The Virtual Service's VIP address will become unreachable. C. New client connections will be automatically directed to the two remaining healthy Service Engines, and existing connections will attempt to reconnect. D. All client traffic will be dropped until the failed Service Engine is recovered.

Correct Answer: C

QUESTION NO: 2
A DevOps engineer is creating a script to parse Avi logs and automatically alert the security team about high-severity WAF events. The script needs to differentiate between a simple log of a WAF- inspected-but-clean request and a log of a request that was actively blocked. How will the log entries for these two events differ?

A. The blocked request's log entry will be encrypted, while the clean request's log will be in plain text. B. The blocked request will be a "Significant Log", while the clean request will be a "Non-Significant Log". C. The blocked request will not have a "Server IP" field, as it was never sent to the pool. D. The blocked request will have a different "VIP" address in the log entry.

Correct Answer: B

QUESTION NO: 3
An Avi Administrator has upgraded the Controller cluster and is now ready to upgrade the Service Engines. The environment contains a mix of Service Engine Groups. One critical SEG, 'SEG- PROD-CRITICAL', cannot tolerate any downtime or performance degradation. The SEs in this group are already running at high capacity. What is the safest upgrade strategy for this specific SEG?

A. Perform a Simultaneous upgrade during a maintenance window. B. Disable the health monitors for all pools in this SEG before starting a Rolling upgrade. C. Before the upgrade, manually add a new Service Engine to the group, then perform a Rolling upgrade. D. Manually migrate all Virtual Services to a different SEG, upgrade the empty SEG, and then migrate them back.

Correct Answer: C

QUESTION NO: 4
Which deployment mode allows Avi to work directly with a VMware vSphere environment?

QUESTION NO: 5
Which command is commonly used to access the Avi CLI from the controller?

A. connect se B. ssh admin@controller C. login avi D. avi-shell

Correct Answer: B

QUESTION NO: 6
A vSphere Administrator is reviewing two different HA configurations in Avi. Configuration A is a Service Engine Group in N+M mode. Configuration B is a Virtual Service scaled out across multiple SEs. What is the fundamental difference between these two HA models?

A. N+M is used for L4 virtual services, while Active/Active is used for L7 virtual services. B. N+M requires manual intervention to fail over, while Active/Active is fully automated. C. N+M is an Active/Standby model for SEs, while Active/Active (scale out) is an Active/Active model for the Virtual Service itself. D. N+M provides protection against SE failure, while Active/Active (scale out) provides protection against backend server failure.

Correct Answer: C

QUESTION NO: 7
An Avi Administrator is configuring a new Service Engine Group to host many small, non-critical virtual services. The primary goal is resource efficiency. The administrator wants to have a shared pool of standby Service Engines that can take over if any active SE fails. For example, if there are 20 active SEs, the administrator wants to have 2 standby SEs available for the entire group. Which HA mode for the Service Engine Group achieves this?

A. Cold Standby B. Active/Standby C. N+M D. Active/Active

Correct Answer: C

QUESTION NO: 8
A Virtual Service is configured with an SSL Profile that includes a primary certificate (cert-a) and is also part of a Certificate Chain (cert-b). A client connects and its browser only trusts cert-b.
How does the Avi Service Engine handle the SSL/TLS handshake?

A. The Service Engine will present both cert-a and cert-b to the client during the handshake. B. The Service Engine will only present cert-a, causing the client's connection to fail. C. The Service Engine will choose to present either cert-a or cert-b based on the client's IP address. D. The Service Engine will present cert-b first, and if the client rejects it, it will then present cert-a.

Correct Answer: A

QUESTION NO: 9
A vSphere administrator is deploying a new Avi Controller in an environment with strict security policies. The security team requires that all management traffic be isolated. After deploying the OVA and assigning an IP address, the administrator is unable to access the web UI. Which default port must be allowed on the network firewall between the administrator's workstation and the Avi Controller's management IP to enable UI access?

A. 22 (SSH) B. 80 (HTTP) C. 443 (HTTPS) D. 8443 (HTTPS Alternate)

Correct Answer: C

QUESTION NO: 10
A security administrator is reviewing logs after a potential security incident. The administrator needs to find all requests that were blocked by the Web Application Firewall (WAF). In the Virtual Service logs, what information should the administrator filter for to isolate these specific events?

A. Filter for logs that have a WAF section where the Action is Block. B. Filter for logs that are flagged as Non-Significant. C. Filter for logs where the Response Code is 403. D. Filter for logs where the Connection End Type is TCP_RESET_FROM_PROXY.

Correct Answer: A

QUESTION NO: 11
A Virtual Service is configured with a System-L7 profile and has policies for content switching and header manipulation. Where are these L7 policies actually executed?

A. On the backend server, which has an Avi agent installed on it. B. On the client's browser, via a script downloaded from the Avi Controller. C. On the Service Engine, after it has terminated the client's TCP and SSL/TLS connections. D. On the Avi Controller, which then instructs the backend server on how to route the request.

Correct Answer: C

QUESTION NO: 12
A Service Engine Group is configured with an N+M HA mode where N=5 and M=1. An administrator performs a "manual failover" on one of the active SEs. What is the expected outcome?

A. All Virtual Services on the selected SE are migrated to the single buffer ('M') SE, and the original SE becomes a standby. B. The selected SE is deleted, and its Virtual Services are automatically recreated. C. A new buffer SE is created, and the Virtual Services are moved to it. D. The selected SE is rebooted, and its Virtual Services experience a brief outage.

Correct Answer: A
