Question 256

Which DCI technology utilizes a "flood and learn" technique to populate the Layer 2 forwarding table?

Correct Answer: C
VPLS (Virtual Private LAN Service) is a Layer 2 VPN technology that simulates a LAN across an MPLS or IP core. VPLS uses a flood-and-learn mechanism where unknown unicast, broadcast, and multicast traffic is flooded to build the forwarding database dynamically - much like a traditional LAN switch.
* This flood-and-learn behavior leads to MAC learning based on incoming traffic, not control-plane advertisement.
* VPLS may require extra control-plane scaling mechanisms in large-scale deployments due to this learning behavior.
Other options explained:
* A (LISP): Uses mapping servers and control plane for EID-to-RLOC mapping, not flood-and-learn.
* B (OTV): Uses control-plane MAC address learning instead of data-plane flooding.
* D (EVPN): Uses BGP control-plane learning for MAC and IP address distribution.

Question 257

You have been tasked with designing a data center interconnect as part of business continuity. You want to use FCoE over this DCI to support synchronous replication. Which two technologies allow for FCoE via lossless Ethernet or data center bridging? (Choose two.)

Correct Answer: A,B
FCoE (Fibre Channel over Ethernet) requires a lossless Ethernet transport, typically achieved using Data Center Bridging (DCB) features such as Priority Flow Control (PFC). Only technologies that can preserve Ethernet frames end-to-end and support lossless characteristics can properly carry FCoE:
* A. DWDM (Dense Wavelength Division Multiplexing): Operates at the physical layer and is transparent to Ethernet, preserving frame integrity and lossless characteristics across long distances.
* B. EoMPLS (Ethernet over MPLS): Carries Ethernet frames directly over MPLS and can be engineered to support low-loss, low-latency transport appropriate for FCoE.
Why other options are incorrect:
* C. SONET/SDH encapsulates Ethernet but is not suitable for FCoE due to differences in timing and buffering.
* D. Multichassis EtherChannel over pseudowire may introduce additional control plane complexity and loss characteristics.
* E. VPLS introduces MAC learning, flooding, and buffering behaviors that can cause frame loss, which is not compatible with FCoE requirements.

Question 258

During evaluation of migrating current on premises infrastructure to add cloud-based infrastructure, a network planning team must meet three core requirements as they make recommendations on which cloud strategy to adopt going forward
* Technology is changing rapidly, therefore the enterprise must be open to adopting new ways of doing things, and be ready to invest CapEx-funds in the next three years
* Network bandwidth capacity requirements are dynamic and are expected to change over the next year
* If new technologies are to be introduced, operational expenses must be kept at a minimum. Which cloud strategy meets these requirements?

Correct Answer: A

Question 259

With virtualization being applied in many parts of the network every physical link is likely to carry one or more virtual links, but what is a drawback in cases like this?

Correct Answer: C

Question 260

Refer to the exhibit.

An engineer is designing the traffic flow for AS 111. Traffic from AS 111 should be preferred via AS 100 for all external routes. A method must be used that only affects AS 111. Which BGP attributes are best suited to control outbound traffic?

Correct Answer: C
The scenario requires controlling how AS 111 sends its outbound traffic (egress traffic). BGP policy control for outbound traffic is best handled via manipulating the BGP Local Preference attribute, as:
* Local Preference (LocalPref) influences path selection for outbound traffic by setting a preference for one path over another.
* It is evaluated within the AS and does not require coordination with external autonomous systems.
* LocalPref changes are fully contained inside AS 111 and satisfy the requirement to only affect AS 111.
* A higher Local Preference value is preferred, thus you set higher values for routes learned via AS 100.
Why other options are incorrect:
* A (community): Typically influences inbound traffic or interacts with upstream providers.
* B (MED): Influences inbound traffic for external neighbors, not outbound.
* D (AS Path): Also primarily influences inbound traffic selection by remote ASes.
