You want to add a configuration that is not supported by Juniper Apstra reference architecture using a configlet.
Which two configurations would be applicable in this scenario? (Choose two.)

  1. static route configuration
  2. policy configuration
  3. syslog configuration
  4. NTP configuration

Answer(s): C,D

Explanation:

According to the Juniper documentation1, a configlet is a configuration template that augments Apstra's reference design with non-native device configuration. They consist of one or more generators. Each generator specifies a NOS type (config style), when to render the configuration, and CLI commands (and file name as applicable). Some applications for configlets include the following:
Syslog
SNMP access policy
TACACS / RADIUS
Management ACLs
Control plane policing
NTP
Username / password
Therefore, the correct answer is C and D. syslog configuration and NTP configuration. These are examples of non-native device configuration that can be added using a configlet. Static route configuration and policy configuration are not applicable in this scenario, because they are part of the reference design configuration that should not be replaced or modified by a configlet.

Which statement about Juniper Apstra role-based access control is correct?

  1. The viewer role is predefined and can be deleted.
  2. The administrator role can see all permissions.
  3. The user role can create roles.
  4. The administrator role is the only predefined role.

Answer(s): B

Explanation:

Juniper Apstra role-based access control (RBAC) is a feature that allows you to specify access permissions for different users based on their roles. RBAC servers are remote network servers that authenticate and authorize network access based on roles assigned to individual users within an enterprise1. Juniper Apstra has four predefined user roles: administrator, device_ztp, user, and viewer2. The administrator role is the most powerful role, and it can see all permissions and perform all actions in the Apstra software application. The administrator role can also create, clone, edit, and delete user roles, except for the four predefined user roles, which cannot be modified2. Therefore, the statement that the administrator role can see all permissions is correct. The following three statements are incorrect in this scenario:
The viewer role is predefined and can be deleted. This is not true, because the viewer role is one of the four predefined user roles, and it cannot be deleted. The viewer role is the most restricted role, and it can only view the network information and configuration, but not make any changes2. The user role can create roles. This is not true, because the user role is one of the four predefined user roles, and it cannot create roles. The user role can perform most of the network configuration and management tasks, but it cannot access the platform settings or the user management features2.
The administrator role is the only predefined role. This is not true, because there are four predefined user roles, not just one. The other three predefined user roles are device_ztp, user, and viewer2.

You are using Juniper Apstra to design a data center fabric. In this scenario, which object type associates a specific vendor model to a logical device?

  1. templates
  2. device profiles
  3. agent profiles
  4. interface map

Answer(s): B

Explanation:

Device profiles are objects that associate a specific vendor model to a logical device in Juniper Apstra. Device profiles contain extensive hardware model details, such as form factor, ASIC, CPU, RAM, ECMP limit, and supported features. Device profiles also define how configuration is generated, how telemetry commands are rendered, and how configuration is deployed on a device. Device profiles enable the Apstra system to render and deploy the configuration according to the Apstra Reference Design12.

Which two statements are correct about probes? (Choose two.)

  1. Default probes can be cloned, modified, and saved.
  2. Only the variable parameters tor default probes can be edited and saved.
  3. All default probes are enabled for all blueprints.
  4. Default probes are enabled, based on the intent for a blueprint.

Answer(s): A,D

Explanation:

Probes are the basic unit of abstraction in Intent-Based Analytics (IBA). They are used to collect, process, and analyze data from the network and raise anomalies based on specified conditions. Probes are composed of processors and stages that form a directed acyclic graph (DAG) of data flow.
The following statements are correct about probes:
A) Default probes can be cloned, modified, and saved. This is true because Apstra provides a set of default probes that cover common use cases and scenarios. These probes can be cloned and modified to suit the specific needs of the user. The modified probes can be saved as new probes with different names and descriptions. This allows the user to customize and extend the functionality of the default probes.
D) Default probes are enabled, based on the intent for a blueprint. This is true because Apstra enables or disables the default probes automatically based on the intent of the blueprint. The intent of the blueprint is the high-level description of the desired state and behavior of the network. Apstra uses the intent to determine which default probes are relevant and applicable for the blueprint and enables them accordingly. For example, if the intent of the blueprint is to deploy an EVPN-VXLAN fabric, Apstra will enable the default probes related to EVPN-VXLAN, such as EVPN-VXLAN Anomaly Detection, EVPN-VXLAN Fabric Health, and EVPN-VXLAN Fabric Validation. The following statements are incorrect about probes:
B) Only the variable parameters for default probes can be edited and saved. This is false because the user can edit and save any parameters for the default probes, not just the variable ones. The variable parameters are the ones that depend on the network topology, devices, or configuration, such as device names, interface names, IP addresses, VLAN IDs, etc. The user can also edit and save the fixed parameters, such as the duration, threshold, condition, etc. However, the user cannot edit and save the default probes directly. The user must clone the default probes first and then edit and save the cloned probes as new probes.
C) All default probes are enabled for all blueprints. This is false because Apstra does not enable all default probes for all blueprints. Apstra enables the default probes based on the intent of the blueprint, as explained above. This means that only the default probes that are relevant and applicable for the blueprint are enabled. For example, if the intent of the blueprint is to deploy a BGP IP fabric, Apstra will not enable the default probes related to EVPN-VXLAN, since they are not relevant for the blueprint. The user can also manually enable or disable the default probes as needed.
