You use Juniper Apstra to enable a new VXLAN virtual network. Which two components would be automatically derived in this situation? (Choose two.)
A. IP subnet
B. Route Zone
C. VXLAN VNI
D. VLAN-ID
答案：A,C
解題說明：
A VXLAN virtual network is a collection of Layer 2 forwarding domains that span multiple racks in a fabric. A VXLAN virtual network requires a name and a VXLAN network identifier (VNI), which is a 24-bit number that identifies the virtual network. The VNI can be either explicitly assigned or auto-assigned from a resource pool. A VXLAN virtual network can also have Layer 3 connectivity, which enables routing between different VNIs within a routing zone. A routing zone is an L3 domain that isolates the IP traffic of different tenants. A routing zone can have one or more VNIs associated with it. To enable Layer 3 connectivity, a VXLAN virtual network needs an IP subnet, which is a range of IP addresses that can be assigned to the hosts in the virtual network. The IP subnet can be either explicitly assigned or auto-assigned from a resource pool. Therefore, the correct answer is A and C. IP subnet and VXLAN VNI are two components that would be automatically derived when enabling a new VXLAN virtual network using Juniper Apstra.
問題 #78
In Juniper Apstra, which statement is correct?
A. VMware anomaly detection is on by default.
B. VMware anomaly detection requires a VMware hypervisor with exports enabled.
C. VMware anomaly detection requires an Apstra server running on VMware.
D. VMware anomaly detection requires a vCenter server configured under External Systems
答案：D
解題說明：
VMware anomaly detection is a feature of Apstra that provides visibility and validation of the virtual network settings and the physical network settings in a VMware vSphere environment. To enable this feature, Apstra requires a connection to a vCenter server that manages the ESX/ESXi hosts and the VMs connected to the Apstra-managed leaf switches. The vCenter server must be configured under External Systems in the Apstra web interface, and the vCenter integration must be staged and committed in the blueprint. This allows Apstra to collect information about VMs, ESX/ESXi hosts, port groups, and VDS, and to flag any inconsistencies or mismatches that might affect VM connectivity.
問題 #79
A member of your organization made changes to a predefined interface map using Juniper Apstra. Which two statements are correct in this scenario? (Choose two.)
A. Changes to interface maps in the global catalog will raise anomalies that may need to be addressed at the next commit.
B. Any changes made to predefined interface maps are discarded when Apstra is upgraded.
C. Changes made to predefined interface maps will not have an impact on the Apstra software.
D. Changes to interface maps in the global catalog do not affect interface maps that have already been imported into blueprint catalogs
答案：B,D
解題說明：
An interface map is a configuration template that maps interfaces between logical devices and physical hardware devices (represented with device profiles) while adhering to vendor specifications. An interface map can be either predefined or custom. A predefined interface map is one that ships with Apstra software and supports most qualified Juniper devices. A custom interface map is one that is created by the user to meet specific requirements. An interface map can be stored in either the global catalog or the blueprint catalog. The global catalog contains all the interface maps that are available for use in any blueprint. The blueprint catalog contains the interface maps that are imported from the global catalog and used in a specific blueprint.
問題 #80
Referring to the exhibit, which role does Device A serve in an IP fabric?
A. spine
B. server
C. leaf
D. super spine
答案：A
解題說明：
Device A serves as a spine in an IP fabric. An IP fabric is a network architecture that uses a spine-leaf topology to provide high performance, scalability, and reliability for data center networks. A spine- leaf topology consists of two layers of devices: spine devices and leaf devices.
Spine devices are the core devices that interconnect all the leaf devices using equal-cost multipath (ECMP) routing. Leaf devices are the edge devices that connect to the servers, storage, or other network devices. In the exhibit, Device A is connected to four leaf devices using multiple links, which indicates that it is a spine device.
問題 #81
Which statement about Juniper Apstra role-based access control is correct?
A. The administrator role can see all permissions.
B. The user role can create roles.
C. The administrator role is the only predefined role.
D. The viewer role is predefined and can be deleted.
答案：A
解題說明：
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 enterprise. Juniper Apstra has four predefined user roles: administrator, device_ztp, user, and viewer. 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 modified. Therefore, the statement that the administrator role can see all permissions is correct.
