A company requires redundancy for its multihomed BGP external connections. What two features can be configured on the WAN routers to automate failover for both outbound and inbound traffic? (Choose two.)

What are two methods of ensuring that the multicast RPF check passes without changing the unicast routing table? (Choose two.)

Which option is correct when using Virtual Switching System to combine two physical switches into one logical switch?

Which virtualization technology uses Layer 3 BFD to detect network failures between network devices?

A network engineer is designing a network that must incorporate active-active redundancy to eliminate disruption when a link failure occurs between the core and distribution layer. What two technologies will allow this? (Choose two.)

What is an advantage of using the vPC feature in a data center environment?

An organization is using a link state routing protocol that is not dependent on IP addressing. Which action should be taken to enable routing across area boundaries in this environment?

A network engineer must select a network technology to simplify the extension of Layer 2 networks between data centers with a requirement of less than 4,000
VLANs. Which two network technologies accomplish this requirement? (Choose two.)

An organization is acquiring another company and merging the two company networks. No subnets overlap, but the engineer must limit the networks advertised to the new organization. Which feature implements this requirement?

A company requires a simple network access control solution that allows for software defined segmentation based on user and device contextual information.
Which two technologies must be implemented to meet these requirements? (Choose two.)

Multicast has been enabled and configured in the Enterprise, and PIM Sparse-mode has been enabled on all VLANs. What feature is required to stop multicast traffic from being broadcasted on the access layer switches?

An engineer has implemented a QoS architecture that requires a signaling protocol to tell routers which flows of packets require special treatment.
Which two mechanisms are important building blocks to establishing and maintaining QoS in this architecture? (Choose two.)

Which Nexus feature enables you to support server connectivity with one topology and address requirement for both high availability and high bandwidth?

Refer to the exhibit. A customer discovers router R1 remains active even when the R1 uplink (F0/1) is down. Which two comments can be applied to R1 to allow
R2 to take over as the HSRP active? (Choose two.)

During the design of a new data center, a company requires that access switches be placed near servers without requiring a one-to-one ratio of switches to network racks. Which switch layout must be used?

Two companies want to merge their OSPF networks, but they run different OSPF domains. Which option must be created to accomplish this requirement?

In what situation must spanning-tree be implemented?
