The configuration provided in the OCR text shows the use of a route map named RM_LOCAL_PREF to set the local preference for BGP routes received from the neighbor 13.13.13.3. By setting a higher local preference, the BGP best path selection process will prefer routes with a higher local preference value. Therefore, to force traffic to take the path R1-R3-R4, the local preference for routes received from R3 should be increased, making them more preferred than the current path via R2.

Questions no: 670 Verified Answer: A, C Comprehensive and Detailed Explanation: Traditional WANs are known for their hardware focus and manual configuration, which can lead to a high level of control over policy configurations. This control allows for comprehensive configuration standardization (A) across the network. Additionally, because traditional WANs require heavy manual configurations, troubleshooting is often more straightforward since network administrators are intimately familiar with the setup, leading to simplified troubleshooting ©.

 To assign an IP address to the GigabitEthernet1 interface, the engineer needs to ensure that the interface is configured to support IPv4 addressing and then assign the specific IP address. Option B, “Router(config-vrf)#address-family ipv4”, is required to specify that IPv4 addressing is being configured within the VRF. Option E, “Router(config-if)#ip address 192.168.1.1 255.255.255.0”, assigns the specific IP address and subnet mask to the GigabitEthernet1 interface. References := The explanation can be corroborated with information available in Cisco’s official documentation and training materials for Implementing and Operating Cisco Service Provider Network Core Technologies.

 MACsec (Media Access Control Security) is the IEEE 802.1AE standard for securing data on Ethernet networks. It provides end-to-end encryption at the data link layer (Layer 2), ensuring that data is secure as it travels across the physical network infrastructure between two sites. MACsec encrypts each frame with a secure key, providing confidentiality, integrity, and origin authenticity. Unlike IPsec, which operates at the network layer (Layer 3), MACsec operates at a lower level, allowing for line-rate encryption that doesn’t impact the throughput of the network. This makes MACsec an ideal solution for protecting sensitive data in motion without sacrificing performance.
