Cisco 300-320 Online Questions & Answers

• Question 291:

  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.)

  A. policing
  B. classification
  C. admission control
  D. tagging
  E. low-latency queuing
  F. resource reservation
  G. packetscheduling
  B. classification
  F. resource reservation

• Question 292:

  What is the built in native security to ACI?

  A. IPS
  B. Native Deny
  C. EPG to EPG ...
  D. ACL
  B. Native Deny

  ---

  All the traffic between servers is denied (micro segmentation), to allow the traffic between EPGs we need to configure contracts.

• Question 293:

  Which multicast implementation strategy provides load sharing and redundancy by configuring intradomain RPs as MSDP peers?

  A. anycast RP
  B. auto-RP
  C. bootstrap router
  D. static RP
  A. anycast RP

  ---

  Anycast RP is a useful application of MSDP. Originally developed for interdomain multicast applications, MSDP used for Anycast RP is an intradomain feature that provides redundancy and load-sharing capabilities. Enterprise customers typically use Anycast RP for configuring a Protocol Independent Multicast sparse mode (PIM-SM) network to meet fault tolerance requirements within a single multicast domain. https://www.cisco.com/c/en/us/td/docs/ios/solutions_docs/ ip_multicast/White_papers/anycast.html#wp1029118

• Question 294:

  An engineer is building a new data center design based on Cisco ACI. For security reasons, certain applications are prevented from communicating directly with each other, and bandwidth requirements exclude the possibility of using an external security appliance. Which solution satisfies these requirements?

  A. Place applications in the same EPG and apply filters
  B. Place applications in separate EPGs
  C. Place applications in separate bridge domains
  D. Place applications in same bridge domain and apply filters
  D. Place applications in same bridge domain and apply filters

• Question 295:

  What need to be added to the R1 configuration to allow R2 be the active in case of R1 failure? (Choose two)

  (There is a diagram showing one switch connected with 2x links to 2x HSRP routers (R1 and R2). They are connected to two user computers. The HSRP configuration for R1 and R2 is the same.

  A. ip track 50 ip route 10.1.1.0 ...
  B. ip track 50 interface f0\1 line-protocol (or ip routing)
  C. track 50 decrement 20
  D. track 50 shutdown
  B. ip track 50 interface f0\1 line-protocol (or ip routing)
  C. track 50 decrement 20

• Question 296:

  Which two technologies can be used to interconnect data centers over an IP network and provide Layer 2 LAN extension? (Choose two.)

  A. IS-IS
  B. VXLAN
  C. TRILL
  D. Fabric Path E. OTV
  B. VXLAN

• Question 297:

  Which option describes the purpose of the auto-cost reference bandwidth 10000 command under the OSPF process?

  A. Recognize redundant 10 Megabit links.
  B. Differentiate cost on a 10 Gigabit Ethernet trunk link.
  C. Change the default bandwidth for a 100 Megabit link.
  D. Adjust the link bandwidth for routing protocols.
  B. Differentiate cost on a 10 Gigabit Ethernet trunk link.

• Question 298:

  A company uses site-to-site IPsec VPN tunnels established over the public internet as a backup to its private WAN. The interoffice IP telephony service quality is degraded when a failover event occurs. What known design limitation can cause this issue?

  A. maximum headend router throughput
  B. circuit bandwidth
  C. transport reliability
  D. number of remote sites
  C. transport reliability

• Question 299:

  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.
  A. Ensure that the network design follows a structured hierarchical topology.
  B. Utilize route summarization on edge devices.

• Question 300:

  What location are security policies enforced in ACI?

  A. End Point
  B. Spine
  C. Leaf
  D. APIC
  C. Leaf
