Q1. What are two of Cisco's best practices at the access layer to ensure rapid link transitions and VLAN consistency? (Choose two.)
A. Deploy RPVST
B. Deploy MSTP
C. Utilize VTP in server/client mode
D. Utilize VTP in transparent mode
E. VLANs span entire network
F. Portfast applied on distribution uplinks
Answer: A,D
Q2. Which option does best practice dictate for the maximum number of areas that an OSPF router should belong to for optimal performance?
A. 1
B. 2
C. 3
D. 4
E. 5
Answer: C
Q3. In a collapsed core design, which three benefits are provided by a second-generation Cisco MDS director? (Choose three.)
A. a higher fan-out ratio
B. fully redundant switches
C. 100 percent port efficiency
D. all ISLs contained within a single chassis
E. higher latency and throughput than a core-edge design switch
Answer: B,C,D
Q4. Which unique characteristics of the Data Center Aggregation layer must be considered by an Enterprise Campus designer?
A. Layer 3 routing between the Access and Aggregation layers facilitates the ability to span VLANs across multiple access switches, which is a requirement for many server virtualization and clustering technologies.
B. "East-west" server-to-server traffic can travel between aggregation modules by way of the core, but backup and replication traffic typically remains within an aggregation module.
C. Load balancing, firewall services, and other network services are commonly integrated by the use of service modules that are inserted in the aggregation switches.
D. Virtualization tools allow a cost effective approach for redundancy in the network design by using two or four VDCs from the same physical switch.
Answer: C
Q5. What is one reason to implement Control Plane Policing?
A. allow OSPF routing protocol to advertise routes
B. protect the network device route processor from getting overloaded by rate limiting the incoming control plane packets
C. allow network devices to generate and receive packets
D. protect the data plane packets
Answer: B
Q6. Given the addresses 10.10.16.0/24 and 10.10.23.0/24, which option is the best summary?
A. 10.10.0.0/16
B. 10.10.8.0/23
C. 10.10.16.0/23
D. 10.10.16.0/21
Answer: D
Q7. Which two design principles should be followed to scale EIGRP properly? (Choose two.)
A. Ensure that the network design follows a structured hierarchical topology.
B. Utilize route summarization on edge devices.
C. Implement multiple autonomous systems, regardless of the size of the network.
D. Tune EIGRP delay metric on all core devices.
E. Configure offset lists on the network border.
Answer: A,B
Q8. What is the correct state between two BGP peers that are neighbors?
A. active
B. operational
C. established
D. up
Answer: C
Q9. Refer to the exhibit. Which two features can enable high availability for first-hop Layer 3 redundancy? (Choose two.)
A. VPC
B. IGMP V2
C. VRRP
D. PIM
E. HSRP
Answer: C,E
Q10. Which option is.correct when.using VSS to combine two physical switches into one logical switch?
A. Both data planes forward traffic simultaneously.
B. Only one data plane forwards traffic, while the other data plane is on standby.
C. Both control planes forward traffic simultaneously.
D. Control planes are combined into one virtual control plane.
Answer: D
