6V0-22.25 시험 - VMware실제시험문제와 답 - 45문항

Question No : 1

What is the impact on a Service Engine's capacity when a WAF (Web Application Firewall) policy is enabled for a virtual service?

A.There is no impact on capacity.
B.The SE's memory and CPU usage will increase.
C.The SE can handle more concurrent connections.
D.The SE will automatically scale up its vCPU count.

정답:
Explanation:
Enabling WAF requires the Service Engine to perform deep packet inspection and match traffic against a ruleset, which consumes additional CPU and memory resources, thereby reducing its overall capacity for other tasks.

Question No : 2

True or False: In an Avi Controller cluster, SSL certificates are stored centrally on the Controller and pushed down to the relevant Service Engines on demand.

A.True
B.False

정답:
Explanation:
Certificate management is centralized on the Avi Controller. This simplifies administration, as certificates only need to be uploaded once and are then automatically distributed to the SEs that host the virtual services using them.

Question No : 3

An administrator wants to redirect all incoming HTTP traffic to HTTPS.
Which Avi feature is best suited for this task?

A.A Health Monitor
B.An Application Profile
C.A Network Profile
D.An HTTP Request Policy

정답:
Explanation:
An HTTP Request Policy can be used to inspect incoming requests and perform actions based on defined rules. A common use case is to match on the protocol (HTTP) and issue a redirect (HTTP 301/302) to the HTTPS version of the site.

Question No : 4

Which of the following settings are typically configured within an Application Profile? (Choose two)

A.The Virtual IP address
B.The load balancing algorithm
C.The application protocol type (e.g., HTTP, TCP, UDP)
D.The TCP connection timeout values

정답:
Explanation:
An Application Profile defines the behavior and settings for a specific type of application traffic. This includes the protocol, timeouts, and other application-specific features like HTTP/2 support or caching. The VIP is part of the Virtual Service, and the algorithm is part of the Pool.

Question No : 5

In the Avi object model, what is the correct hierarchy and interaction?

A.A Virtual Service directs traffic to a Pool, which contains one or more backend Servers.
B.A Pool directs traffic to a Virtual Service, which contains one or more backend Servers.
C.A Server directs traffic to a Pool, which is part of a Virtual Service.
D.A Virtual Service contains a Server, which is part of a Pool.

정답:
Explanation:
The logical flow is that a Virtual Service (defined by a VIP and port) receives traffic and forwards it to a Pool of backend Servers based on the configured algorithm and policies.

Question No : 6

What is the primary trigger for an "elastic scale out" of a virtual service?

A.A backend server in the pool fails its health check.
B.The Avi Controller CPU usage exceeds its threshold.
C.The primary Service Engine handling the virtual service exceeds its CPU or traffic threshold.
D.An administrator manually adds a new server to the pool.

정답:
Explanation:
Elastic scale-out is an automated function where Avi deploys an additional Service Engine for a virtual service when the existing SE reaches a predefined performance limit, ensuring application performance and availability.

Question No : 7

An administrator wants to dedicate a set of Service Engines to a specific set of critical applications.
Which Avi construct should be used?

A.A separate Avi Controller cluster
B.A new Application Profile
C.A dedicated Service Engine Group
D.A custom Health Monitor

정답:
Explanation:
Service Engine Groups are used to partition and isolate Service Engines for different purposes, such as dedicating resources to specific tenants, applications, or environments.

Question No : 8

What does an N+M High Availability configuration for a Service Engine Group provide?

A.All virtual services are active on all SEs in the group simultaneously.
B.The group can sustain the failure of 'M' Service Engines while 'N' SEs remain active.
C.It limits the group to a maximum of 'N' active SEs and 'M' standby SEs.
D.The virtual services are split between two sites, N and

정답:
Explanation:
N+M is an elastic HA model where 'N' is the number of active SEs required to handle the load, and 'M' is the buffer capacity (number of additional SEs) that can fail without impacting services.

Question No : 9

True or False: In an Avi architecture, session persistence (stickiness) can be configured based on the client's source IP address or by using an HTTP cookie.

A.True
B.False

정답:
Explanation:
Avi supports multiple methods for session persistence. Source IP persistence is a common L4 method, while HTTP cookie persistence is a more robust L7 method that works well even if the client's IP address changes.

Question No : 10

Which load balancing algorithm directs new connections to the backend server that currently has the fewest active connections?

A.Round Robin
B.Least Connections
C.Fastest Response
D.IP Hash

정답:
Explanation:
The Least Connections algorithm is dynamic and sends traffic to the server that is currently the least busy, which is ideal for environments where session durations vary significantly.

Question No : 11

What is a key advantage of L7 load balancing over L4 load balancing?

A.It has lower latency.
B.It can make more intelligent routing decisions based on application content.
C.It requires fewer system resources.
D.It supports a wider range of transport protocols.

정답:
Explanation:
L7 load balancing can inspect application-layer data, such as HTTP headers, cookies, and URIs, allowing for more sophisticated and content-aware traffic management.

Question No : 12

A virtual service is configured with an L4 Application Profile.
Which of the following traffic characteristics can it inspect to make load balancing decisions?

A.HTTP Headers
B.SSL Certificate details
C.Source/Destination IP Address and Port
D.The URI path of the request

정답:
Explanation:
Layer 4 load balancing operates at the transport layer of the OSI model. It can only make decisions based on information available at that layer, such as IP addresses and TCP/UDP ports, without inspecting the application-level content.

Question No : 13

In the context of Avi Load Balancer, what does a "distributed data plane" mean?

A.The Controller cluster is geographically distributed.
B.Load balancing services are handled by multiple, lightweight Service Engines placed close to applications.
C.A single, large appliance handles traffic for the entire data center.
D.All configuration is stored locally on each Service Engine.

정답:
Explanation:
A distributed data plane architecture involves using multiple data plane instances (Service Engines) that can be deployed on-demand, close to the applications they are servicing, rather than routing traffic through a centralized chokepoint.

Question No : 14

Which of the following are primary tasks performed by the Avi Controller? (Choose two)

A.Processing client traffic to the virtual IP
B.Storing and managing all configuration policies
C.Executing health monitor checks against backend servers
D.Communicating with the cloud infrastructure orchestrator

정답:
Explanation:
The Avi Controller is the central management plane. It holds all configurations and communicates with the underlying infrastructure (like vCenter or NSX-T). Service Engines handle data plane tasks like processing traffic and health monitors.

Question No : 15

Which component in the Avi architecture is responsible for handling all data plane traffic and executing load balancing decisions?

A.Avi Controller
B.Avi Service Engine
C.Avi Cloud Connector
D.Avi DNS

정답:
Explanation:
The Service Engine (SE. is the distributed data plane component that processes all traffic for virtual services. The Controller is the management plane
