Which CLI mode must be used to configure the BGP keychain in Cisco IOS XR Software?
Answer(s): B
A remote operation center is deploying a set of I-BGP and E-BGP connections for multiple IOS-XR platforms using the same template. The I-BGP sessions exchange prefixes with no apparent issues, but the E-BGP sessions do not exchange routes. What causes this issue?
Refer to the exhibit. An engineer is securing a customer's network. Which command must the engineer use to complete this configuration to prevent a DoS attack?
Answer(s): D
What is the function of the FEC field within the OTN signal structure?
Answer(s): C
What is the primary purpose of application hosting in a service-provider virtualization environment?
In a service-provider virtualization environment, application hosting allows third-party applications to run directly on network devices. This reduces the need for separate infrastructure, enhances operational efficiency, and supports advanced capabilities like deep packet inspection, edge computing, and specialized network services.By hosting applications on network devices, service providers can deliver innovative services and reduce latency for applications requiring direct integration with the network.
What is the primary purpose of routed optical networks?
The primary purpose of routed optical networks is to simplify network operations by collapsing multiple layers (e.g., IP, MPLS, and optical layers) into a single unified architecture. This reduces complexity, improves scalability, and enhances efficiency in managing and operating the network.Key features of routed optical networks include:Integration of routing and optical transport layers.Simplified network management and reduced operational costs.Enhanced performance by enabling direct communication between IP and optical layers withoutintermediate equipment.
DRAG DROP (Drag and Drop is not supported)Drag and drop the 5G RAN architecture types from the bottom next to the corresponding topologies on the right.Select and Place:
Answer(s): A
1. D-RAN: BackhaulIn Distributed RAN (D-RAN), the Radio Unit (RU), Distributed Unit (DU), and Centralized Unit (CU) are co- located at the cell site, and only the backhaul interface connects to the mobile core.2. C-RAN: Front/MID/BackhaulThis is a Centralized RAN (C-RAN) with all three segments -- fronthaul (RU to DU), midhaul (DU to CU), and backhaul (CU to core) -- present. DU and CU are centralized but together.3. C-RAN: Front/BackhaulThe RU connects to a centralized CU, skipping the DU. This represents a C-RAN design with fronthaul and backhaul only.4. C-RAN: MID/BackhaulRU is distributed, but DU is centralized and connects to a remote CU. This scenario omits fronthaul in favor of midhaul and backhaul.
What is the primary purpose of Secure ZTP?
Secure Zero-Touch Provisioning automates the secure onboarding and initial configuration of network devices without manual intervention. It ensures that devices are authenticated and provisioned with trusted software and configuration during first boot, protecting the deployment process from unauthorized access or tampering.
