min_scaleout_per_vs: 1
max_scaleout_per_vs: 4
# ... other settings
ha_mode: N+M
# ... other settings

An Avi Administrator is managing a multi-tenant environment where different applications have varying performance requirements. One tenant reports that their Virtual Service (vs-tenant-A) failed to scale out during a traffic spike. Another administrator mentions that a different Virtual Service (vs- internal-utils) in the same Service Engine Group was undergoing a manual scale-out at the exact same time. The administrator suspects a resource contention issue. Which Avi Controller setting could be adjusted to prevent one Virtual Service's scaling activities from impacting another?

A. Enable 'Dedicated Service Engines' for vs-tenant-A.

B. Increase the se_group_scalable_max_cpu_pct in the cloud configuration.

C. Adjust the placement_mode in the Service Engine Group to 'Compact'.

D. Configure a VS-Scaleout alert with a lower threshold for vs-tenant-A.

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. N+M

B. Active/Standby

C. Cold Standby

D. Active/Active

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

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

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

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

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

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

A DevOps engineer is using the Avi REST API to automate the deployment of a new application.
Which Avi component is the API endpoint for all of these automation scripts?

A. The Virtual IP (VIP) of the application.

B. The vCenter server managing the SE VMs.

An Avi Administrator is analyzing a virtual service with a low Health Score. The administrator drills down into the score components and finds the following details.
- Health Score: 45
- Performance Score: 30
- Resource Score: 90
- Anomaly Score: 95
- Security Score: 100
Based on this information, where is the problem most likely located?

A. The backend servers are running out of CPU or memory.

B. The application is responding to user requests very slowly.

C. There is a sudden, unusual drop in the number of clients.

D. The application is under a WAF attack.

出題：7

Besides handling traffic spikes, what are other key use cases for elastic scale out of a Virtual Service? (Select all that apply.)

A. To perform a hitless upgrade of the Service Engine software.

B. To automatically deploy a new Avi Controller node when the cluster is overloaded.

C. To automatically update the SSL/TLS certificate on a Virtual Service.

D. To provide GSLB services across multiple data centers.

E. To improve the high availability of an application.

F. To fail over a Virtual Service when a Service Engine goes down.

出題：8

A Network Architect is designing a solution where Virtual Services need to be placed on Service Engines that have access to a specific, isolated high-security network. How can Service Engine Groups be used to achieve this?

A. By using a Network Security Policy to restrict traffic from the high-security network to a specific set of SEs.

B. By modifying the System-Default-Group to include a route to the high-security network.

C. By creating a dedicated Service Engine Group and configuring its Service Engines' network interfaces to connect to the high-security vSphere port group.

D. This is not possible; all Service Engines must have identical network connectivity.

出題：11

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

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

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

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

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

- Server `10.10.1.6`: DOWN (Health Monitor: tcp-hm failed)
- Server `10.10.1.7`: DOWN (Health Monitor: tcp-hm failed)
Based on these analytics, what are the most likely causes of the user-reported errors? (Choose
2.)

A. The WAF policy is too restrictive and is blocking valid requests.

B. Two of the three backend servers in the pool are failing their health checks and are marked down.
