Using Juniper Apstra. which component is defined in a template?
Correct Answer: A
A template is a configuration template that defines a network's policy intent and structure. A template can be either rack-based or pod-based, depending on the type and number of racks and pods in the network design. A template includes the following details: Policies: These are the parameters that apply to the entire network, such as the overlay control protocol, the ASN allocation scheme, and the underlay type. Structure: This is the physical layout of the network, such as the type and number of racks, pods, spines, and leaves. The structure also defines the leaf-to-spine interconnection, which is the number and type of links between the leaf and spine devices. The leaf-to-spine interconnection can be either single or dual, depending on the redundancy and bandwidth requirements. Therefore, the correct answer is A. the leaf-to-spine interconnection. This is a component that is defined in a template, as it determines the physical connectivity of the network. The speed of the links, the number of spine devices, and the definition of IP pools are not components that are defined in a template, as they are either derived from the device profiles, the resource pools, or the blueprint settings.
Question 72
In a three-stage Clos network, what are important key design aspects of a data center fabric? (Choose two.)
Correct Answer: B,C
Fabric traffic enters and exits the border devices: In a three-stage Clos fabric, border leaf devices serve as the gateway between the internal fabric and external networks, such as the internet or WAN. Servers are connected to leaf devices: Leaf switches are responsible for connecting endpoints like servers, storage systems, or other access layer devices.
Question 73
Which three multihoming mechanisms are supported in the Juniper Apstra rack design? (Choose three.)
Correct Answer: A,D,E
In Juniper Apstra rack designs, the supported multihoming mechanisms are: - vPC (Virtual Port Channel) for multihoming with certain vendor devices. - ESI (Ethernet Segment Identifier), part of EVPN multihoming. - MLAG (Multi-Chassis Link Aggregation Group) for providing multihoming and redundancy.
Question 74
Which statement is true when onboarding a Juniper Networks device using a Juniper Apstra ZTP server?
Correct Answer: B
The ztp.Json file on the Apstra ZTP server contains the configuration parameters for each device that is onboarded using ZTP. One of the parameters is the State, which can be one of the following values: init, ready, in_progress, done, error, or disabled. The State indicates the current status of the device in the ZTP process. For example, if the State is ready, it means that the device is ready to be onboarded by the Apstra ZTP server. If the State is done, it means that the device has completed the ZTP process and is managed by the Apstra server. The State can be manually set or changed in the ztp.Json file to control the behavior of the device during ZTP.
Question 75
What are two types of policies that Juniper Apstra uses to push to switches using Security Policies? (Choose two.)
Correct Answer: B,D
Firewall filters are one of the policy types that Juniper Apstra pushes to switches to enforce security rules. Access control lists (ACLs) are also used by Apstra security policies to control traffic flows at the switch level.
