# vCenter Cloud Configuration
Management Network:
- Port Group: pg-avi-management
...
Data Networks:
...

A. It must be a trunk port group allowing all VLANs.

B. It must be configured with DHCP enabled.

C. It must have a route to the Avi Controller's management IP address.

D. It must be the same port group used by the Avi Controller VMs.

正解: C

質問 4

A Network Architect is designing a new, highly resilient application deployment. The design requires creating a single virtual service that is simultaneously active on multiple Service Engines.
If one Service Engine fails, traffic should continue to be processed by the remaining active Service Engines without interruption. What combination of settings is required when creating the virtual service to achieve this? (Select all that apply.)

A. Set the Virtual Service's 'Max Number of Service Engines' to a value greater than 1.

B. The Virtual Service must be configured with an L4 Application Profile.

C. Set the ha_mode of the Service Engine Group to N+M.

D. The Virtual Service's HA mode must be effectively set to Active/Active.

E. A GSLB service must be configured to distribute traffic to the SEs.

F. Attach a custom alert with a control script to the virtual service.

正解: A,D

質問 5

An administrator is tasked with temporarily disabling all WAF processing for a specific Virtual Service to perform a baseline performance test. They need to ensure that the WAF engine does not inspect any traffic for this VS, but they want to keep the WAF configuration in place to re- enable it easily after the test.
The current WAF configuration for the Virtual Service is shown below.
# Virtual Service > WAF Policy
WAF Policy: custom-waf-policy-prod
Mode: Enforcement
What is the most direct and appropriate method to achieve this?

A. SSH into the Service Engine and stop the WAF process.

B. Delete the 'custom-waf-policy-prod' WAF Policy.

C. In the Virtual Service editor, set the WAF Policy to 'None'.

D. In the WAF Policy 'custom-waf-policy-prod', uncheck all signature rules.

正解: C

質問 6

An application requires load balancing for both a TCP-based control channel on port 5001 and a UDP-based data stream on port 5002. An administrator wants to create a single Virtual Service to handle both. Which features of an L4 Virtual Service make this possible?

A. A single Virtual Service can be configured with multiple Service Ports, one for TCP and one for UDP.

B. The System-L4 Application Profile must be modified to include a custom UDP setting.

C. It is not possible; a separate Virtual Service must be created for TCP and UDP.

D. A DataScript must be used to differentiate between the TCP and UDP traffic.

正解: A

質問 7

An application owner reports that their application is "down". An Operator checks the Avi dashboard and finds that the Health Score for the corresponding virtual service is 1. The Operator observes that all four components of the Health Score (Performance, Resource, Anomaly, Security) are extremely low. What are the possible root causes for such a catastrophic failure?
(Select all that apply.)

A. A network outage has occurred between the Avi Controller and the Service Engines.

B. The "Log Successful Checks" option on the health monitor was disabled.

C. The single Service Engine hosting the virtual service has crashed or lost power.

D. The virtual service's VIP address has been misconfigured on the upstream router.

E. All backend servers in the pool are powered off or have lost network connectivity.

F. The administrator's password for the Avi Controller UI has expired.

正解: C,E

質問 8

An Operator is troubleshooting a stateful application where users are complaining that their sessions are being intermittently dropped. The Virtual Service is configured with a Cookie Persistence profile. The Operator suspects that some backend servers are flapping (going up and down quickly). How would this server flapping behavior affect client persistence? (Select all that apply.)

A. The Service Engine will send an HTTP 503 error to the client until the original persisted server comes back online.

B. The load balancing algorithm will be permanently changed to Round Robin for all clients.

C. When a new server is selected, the client will lose their original session state, as it existed only on the failed server.

D. It has no effect; the persistence cookie will always redirect the user to the correct server, even if it's down.

E. The persistence cookie on the client's browser will be automatically deleted by the Service Engine.

F. If the persisted server is marked DOWN by the health monitor, the Service Engine will select a new server for the client's request.

正解: C,F

質問 9

A Security Administrator is configuring a policy to add an HSTS (HTTP Strict Transport Security) header to all HTTPS responses to improve security. Which policy type and execution point should be used?

A. An HTTP Request Policy

B. A DNS Policy

C. A Network Security Policy

D. An HTTP Response Policy

正解: D

質問 10

An administrator is troubleshooting an application where backend servers are intermittently failing. Which component of the Avi architecture is responsible for actively sending probes to the backend servers to check their health?

A. The Virtual Service

B. The Service Engine

C. The Avi Controller

D. The Pool

正解: B

質問 11

A vSphere Administrator is tasked with deploying a new Avi Controller OVA into the vCenter environment. Which file format should the administrator look for to begin the deployment?

A. .OVA

B. .ISO

C. .VHD

D. .VMDK

正解: A

質問 12

An administrator is configuring a Service Engine Group for a vCenter cloud. The "VS Placement Mode" is set to "Compact". What is the expected behavior of the Avi Controller when placing a new Virtual Service into this SEG?
# Service Engine Group Configuration
Name: seg-compact-placement
VS Placement Mode: Compact
Max VS per SE: 20

A. The Controller will always create a new Service Engine for the new Virtual Service.

B. The Controller will randomly select a Service Engine to host the new Virtual Service.

C. The Controller will distribute Virtual Services evenly across all available Service Engines to keep utilization low on each one.

D. The Controller will try to place the new Virtual Service on an existing Service Engine that is already running other VSs, as long as it is below its max_vs_per_se limit.

正解: D

質問 13

A DevOps Engineer is configuring a Virtual Service for a modern web application. Which feature is only available when using an L7 Application Profile (like System-HTTP) and is not possible with an L4 profile?

B. Terminating the client's TCP connection.

C. Performing a TCP health check on the backend servers.
