1. Question 1

   An engineer must interconnect customer data centers by using a 10-Gbps. unicast-only, Layer 3 circuit The requirement is to stretch the Layer 2 connection over the tunnel isolate STP traffic and create more than two million logical network segments Much solution meets these requirements?

   AIPsec over GRE
   

   BOTV
   

   Cdark fiber
   

   DVXLANEVPN
   

   Correct answer: D

   
   

2. Question 2

   An engineer is implementing a Cisco UCS environment The requirements for the solution are for the MAC addresses to be learned only on the server-facing ports. The use of the Spanning Tree Protocol must be avoided. Also, the engineer must have deterministic traffic handling from blades to uplink ports.

   Which two settings must be selected to meet these requirements? (Choose two.)

   Aend-host mode
   

   Bdynamic pinning
   

   CNPIV mode
   

   Dstatic pinning
   

   Eswitching mode
   

   Correct answer: A, D

   These two settings meet the requirements for the Cisco UCS environment:

   • Disable Spanning Tree Protocol (STP):
     • Eliminates STP overhead and complexity from the UCS fabric
     • Prevents STP-related port blocking and convergence delays
     • Enables deterministic traffic handling without STP recalculation
     • Requires a loop-free design (which UCS provides through controlled fabric topology)
   • Enable MAC address learning on server-facing ports only:
     • Restricts MAC learning to blade server-facing ports to prevent unnecessary MAC table entries
     • Ensures deterministic forwarding decisions from blades to uplink ports
     • Reduces MAC table overhead and improves lookup performance
     • Prevents MAC entries learned from uplink traffic from interfering with blade-to-uplink forwarding
   • Combined effect: These settings eliminate STP overhead while ensuring predictable, deterministic traffic paths from server blades to uplink ports based on MAC addresses learned from the blade side

   This configuration provides the operational simplicity and performance characteristics required for UCS fabric design.

3. Question 3

   Which type of encoding is used on 8-Gbps links as compared to 10-Gbps links?

   A8-Gbps links use 64B/66B encoding, and 10-Gbps links use 8B/10B encoding.
   

   B8-Gbps links use 8B/10B encoding, and 10-Gbps links use 64B/66B encoding.
   

   C8-Gbps links and 10-Gbps links use 8B/10B encoding.
   

   D8-Gbps links and 10-Gbps links use 64B/66B encoding.
   

   Correct answer: B

   8-Gbps Fibre Channel links use 8b/10b encoding, while 10-Gbps links use 64b/66b encoding.

   8b/10b encoding converts 8 bits of data into 10 bits for transmission, resulting in a 20% overhead. This was the standard for 8-Gbps and earlier Fibre Channel speeds.

   64b/66b encoding converts 64 bits into 66 bits, resulting in only 3.125% overhead, making it more efficient for higher-speed 10-Gbps and faster links.

   The transition from 8b/10b to 64b/66b represents an improvement in bandwidth efficiency as Fibre Channel speeds increased.

4. Question 4

   A network administrator must create a redundant vHBA for the mission-critical virtual machines (VMs) installed on a Cisco UCS Fabric Interconnect blade server. The VMs access multiple datastores using VSAN55 and VSAN95. The datastore on which the VMs are hosted must be accessible if any of the uplinks goes offline. Which action meets these requirements?

   AAttach VSAN55 to vHBA1 and VSAN95 to vHBA2.
   

   BAssign VSAN55 and VSAN95 to vHBA1 and vHBA2.
   

   CEnable failover for the vHBA with VSAN55 and VSAN95 enabled.
   

   DConfigure load-balancing for vHBAs with VSAN55 and VSAN95 attached.
   

   Correct answer: B

   
   

5. Question 5

   Refer to the exhibit.

   

   Refer to the exhibit. A 4x10G Fibre Channel has been configured between SW1 and SW2 to carry backup traffic sourced to and from the SAN. An engineer noticed that 10G Link 1 is being used more heavily than the other links within the port channel. Which action must the engineer take on the two switches to ensure that the traffic uses all available links between SW1 and SW2?

   AConfigure exchange-based load-balancing.
   

   BConfigure flow-based load-balancing.
   

   CConfigure src-dst-ip-based load-balancing.
   

   DConfigure dst-mac-based load-balancing.
   

   Correct answer: A

   When a single link in a port channel is being used more heavily than others, the issue is likely related to the load-balancing algorithm. To ensure traffic is distributed across all available 10G links in the port channel:

   • Enable LACP: Ensure LACP (Link Aggregation Control Protocol) is configured on both SW1 and SW2 for dynamic port channel negotiation.
   • Configure Load Balancing: Set the port channel load-balancing algorithm to 'source-destination IP hash' (or equivalent symmetric hashing). The default 'source-destination MAC' hash may cause uneven distribution if traffic patterns are skewed.
   • Why this matters: If Link 1 is overused, the current algorithm may not be distributing flows evenly. An IP-based hash considers both source and destination IP addresses, which typically provides better distribution for most traffic patterns.

   This configuration ensures that backup traffic flows are evenly distributed across all four links, maximizing throughput and preventing bottlenecks.
