In a multihomed OTV network, it is essential to configure the remote OTV AEDs (Authoritative Edge Devices) to use both the primary and secondary adjacency servers for redundancy and resiliency. The correct configuration, Option D, includes theotv use-adjacency-servercommand with both IP addresses of the primary and secondary servers followed byunicast-only, which indicates that the AEDs should use unicast connections to the adjacency servers instead of multicast.

The cloud model that meets the requirement of having full control over the underlying OS, data and application is Infrastructure as a Service (IaaS). IaaS is a cloud service model that provides the customer with access to virtualized computing resources, such as servers, storage, and networks, over the internet. The customer can install, configure, and manage the OS, data, and application of their choice on the rented infrastructure, without having to worry about the maintenance or security of the physical hardware. IaaS offers the customer the highest level of flexibility and control over their cloud environment, compared to other cloud models such as Platform as a Service (PaaS) or Software as a Service (SaaS).Reference:=

The destination IP address for the vPC keepalive packets sent by the switch is 192.168.254.1. This is indicated in the packet capture output, where ICMP Echo (ping) requests are being sent to this address as part of the keepalive mechanism to ensure the vPC peer link is operational.

The command in question is likely to temporarily suspend the Protocol Independent Multicast (PIM) join messages. This action does not delete the PIM database or flush the Multicast Routing Information Base (MRIB), nor does it suspend multicast traffic forwarding. Instead, it interrupts the PIM join messages, which are used to build and maintain the multicast distribution tree.

The checkpoint named ''system-fm-vrrp'' was created by an admin, as indicated by the description ''Created by Feature Manager.'' This suggests that it was a deliberate action rather than an automatic response to a service restart or crash. Checkpoints in Cisco systems can be manually created for various reasons, such as before making significant changes to the configuration, which allows for a rollback to a known good state if necessary.

Two capabilities of the Cisco Network Assurance Engine are that it validates that devices comply with network security policies and that it predicts the impact of changes to the network. The Cisco Network Assurance Engine is a software solution that uses mathematical modeling and verification techniques to continuously analyze the state and configuration of the data center network. It can validate that the network devices are compliant with the intended security policies, such as access control lists, firewall rules, and encryption standards. It can also predict the impact of planned or unplanned changes to the network, such as software upgrades, configuration changes, or device failures, and provide proactive recommendations to avoid or resolve issues. The Cisco Network Assurance Engine helps to ensure that the network is always operating as intended and aligned with the business objectives.Reference:=

An advantage of streaming telemetry over SNMP is that it supports periodic push-based subscription messages. Streaming telemetry is a method of collecting and transporting network data from devices to a receiver, such as a collector or a dashboard. Streaming telemetry allows the devices to send data periodically or on-demand, based on a subscription model. The receiver can subscribe to specific data sets or events that it is interested in, and the device will push the data to the receiver as it becomes available. This reduces the overhead and latency of polling the device status using SNMP, and provides more granular and real-time visibility into the network state and performance.Reference:=

In OSPF, the router with the highest priority on a network becomes the Designated Router (DR), responsible for generating LSAs for the network. By default, all Cisco routers have an OSPF priority of 1. To ensure that SW2 becomes the DR and controls the LSA floods, its priority needs to be the highest in the OSPFv2 area. The command in option A sets the OSPF priority to the maximum value of 255, which will make SW2 the most likely candidate to be elected as the DR, provided that no other router has a higher priority or a higher router ID if priorities are equal.

The MAC address that is an HSRP version 2 address is 0000.0C9F.F0C8. HSRP (Hot Standby Router Protocol) is a protocol that provides redundancy and load balancing for IP networks by allowing multiple routers to share a virtual IP address and MAC address. HSRP version 2 supports up to 4096 groups, and uses a different MAC address format than HSRP version 1. The MAC address format for HSRP version 2 is 0000.0C9F.FXXX, where XXX is the hexadecimal value of the group number. For group 200, the hexadecimal value is C8, so the MAC address is 0000.0C9F.F0C8.Reference:=
