Q161. A network engineer is designing an access layer that requires all uplinks to be active. Furthermore, VLANs must span across the entire switch block. What design fulfills this requirement? 

A. Layer 2 looped triangle 

B. Layer 2 looped square 

C. Layer 2 loop-free U 

D. Layer 2 loop-free inverted U 

Answer:


Q162. In what situation must spanning-tree be implemented? 

A. when first hop redundancy protocol exists with redundant Layer 2 links between distribution switches 

B. when a VLAN spans access layer switches to support business applications 

C. when trunks need to extend multiple VLANs across access switches 

D. when it is necessary to speed up network convergence in case of link failure 

Answer:


Q163. What two features are inherent advantages of MPLS VPN services? (Choose two.) 

A. service providers can provide additional services 

B. virtual private networks segment traffic and ensure privacy 

C. easier to troubleshoot than Layer 2 WAN technologies 

D. faster data transfer speeds at lower costs 

E. functions without Cisco Express Forwarding 

Answer: A,B 


Q164. Which statement about vPC technology is true? 

A. It allows a device to connect to two separate upstream devices as if they were a single device. 

B. It provides the ability to pair two servers in the data center. 

C. It promotes better STP designs in the switching infrastructure. 

D. It supports IEEE 802.1Q only. 

Answer:


Q165. A network engineer must perform posture assessments on Cisco ASA remote access VPN clients and control their network access based on the results. What mode is the Cisco best practice NAC deployment design for this situation? 

A. Layer 2 in-band real IP gateway mode 

B. Layer 2 out-of-band real IP gateway mode 

C. Layer 3 in-band virtual gateway mode 

D. Layer 3 out-of-band virtual gateway mode 

Answer:


Q166. The requirement for high availability within the Data Center network may cause the designer to consider which one of the following solutions? 

A. Construct a hierarchical network design using EtherChannel between a server and two VDCs from the same physical switch 

B. Utilize Cisco NSF with SSO to provide intrachassis SSO at Layers 2 to 4 

C. Define the Data Center as an OSPF NSSA area, advertising a default route into the DC and summarizing the routes out of the NSSA to the Campus Core 

D. Implement network services for the Data Center as a separate services layer using an active/active model that is more predictable in failure conditions 

Answer:
