In the Juniper Apstra Ul. which two resource types would be created in the Resources menu? (Choose two.)

  1. bridge domain identifier (BDI)
  2. DHCP pools
  3. ASN pools
  4. IP pools

Answer(s): C,D

Explanation:

According to the Juniper documentation1, the Resources menu in the Juniper Apstra UI allows you to create and manage various types of resources that are assigned to different elements of the network.
Resources include the following types:
IPv4 (including Host IPv4)
IPv6 (including Host IPv6)
ASN (autonomous system number)
VNI (virtual network identifier)
VLAN (virtual local area network)
Integer (used for pool type VLAN in local pools in Freeform blueprints) Therefore, the correct answer is C and D. ASN pools and IP pools are two types of resources that can be created in the Resources menu. Bridge domain identifier (BDI) and DHCP pools are not applicable in this scenario, because they are not part of the resources types supported by Juniper Apstra.

In the Juniper Apstra Ul. you are creating a VNI pool for virtual networks.
In this scenario, which VNI range is acceptable?

  1. Any range is acceptable for the VNI pool.
  2. The valid VNI range is 4096 through 16777214.
  3. The valid VNI range is 2 through 4096.
  4. The valid VNI range is 1 through 10000.

Answer(s): B

Explanation:

In the Juniper Apstra UI, you can create VNI pools for virtual networks that use VXLAN encapsulation in the overlay network. A VNI pool is a resource pool that contains a range of VNIs that can be assigned to the virtual networks. The valid VNI range for a VNI pool is 4096 through 16777214, according to the VXLAN standard1. Therefore, the statement B is correct in this scenario. The following three statements are incorrect in this scenario:
Any range is acceptable for the VNI pool. This is not true, because the VNI range has a lower and upper limit defined by the VXLAN standard1. The lower limit is 4096, and the upper limit is 16777214. Any VNI outside this range is invalid and cannot be used for VXLAN encapsulation. The valid VNI range is 2 through 4096. This is not true, because the VNI range does not start from 2, but from 4096. The VNIs from 2 to 4095 are reserved and cannot be used for VXLAN encapsulation1. The valid VNI range is 1 through 10000. This is not true, because the VNI range does not include 1, which is also reserved and cannot be used for VXLAN encapsulation1. The VNI range also does not end at 10000, but at 16777214, which is the maximum possible value for a 24-bit VNI field1.

Exhibit.



Which two statements ate correct about the graph query output shown in the exhibit? (Choose two.)

  1. The interface has an IP address assigned to it.
  2. The output shows a LAG connection.
  3. The switch in the output is a Juniper device.
  4. The interface has tags assigned to it.

Answer(s): B,C

Explanation:

The graph query output shown in the exhibit is a JSON representation of an interface node and its properties in the Apstra graph database. Based on the output, we can infer the following statements:
The output shows a LAG connection. This is true because the interface node has a property called lag_mode which is set to lacp_active, indicating that the interface is part of a link aggregation group (LAG) that uses the Link Aggregation Control Protocol (LACP) to negotiate the link state and parameters12.
The switch in the output is a Juniper device. This is true because the interface node has a property called if_name which is set to ae2, indicating that the interface name follows the Juniper naming convention for aggregated Ethernet interfaces34.
The interface has an IP address assigned to it. This is false because the interface node has properties called ipv4_addr and ipv6_addr which are both set to null, indicating that the interface does not have any IPv4 or IPv6 address configured2.
The interface has tags assigned to it. This is false because the interface node has a property called tags which is set to null, indicating that the interface does not have any tags associated with it2.

Which statement is correct about the Juniper Apstra Rendered configuration?

  1. It is built at commit time and stored in a MySQL database.
  2. It is stored in a NoSQL database and incrementally updated.
  3. It is dynamically tendered at commit time.
  4. It is rendered from the graph database and stored locally.

Answer(s): C

Explanation:

The Juniper Apstra Rendered configuration is the configuration that is generated from the staged blueprint and applied to the devices in the network. The Rendered configuration is dynamically rendered at commit time, which means that it is created on the fly based on the latest changes and validations in the blueprint. The Rendered configuration is not stored in any database, but it can be viewed in the Apstra UI or downloaded as a file. The Rendered configuration reflects the desired state of the network as defined by the intent of the blueprint. The other options are incorrect because:
A) It is built at commit time and stored in a MySQL database is wrong because the Rendered configuration is not stored in any database, let alone a MySQL database. Apstra uses a graph database to store the network topology and configuration data, not a relational database like MySQL. B) It is stored in a NoSQL database and incrementally updated is wrong because the Rendered configuration is not stored in any database, let alone a NoSQL database. Apstra uses a graph database to store the network topology and configuration data, not a non-relational database like NoSQL. The Rendered configuration is not incrementally updated, but dynamically rendered at commit time.
D) It is rendered from the graph database and stored locally is wrong because the Rendered configuration is not rendered from the graph database, but from the staged blueprint. The graph database stores the network topology and configuration data, but the Rendered configuration is generated from the blueprint, which is a logical representation of the network design and intent. The Rendered configuration is not stored locally, but it can be downloaded as a file if needed.
