Demo Questions

Question 1
Which security function is inherent in an Application Centric Infrastructure network?
  1. Default Inter-EPG connectivity
  2. Intrusion Detection
  3. Default Denial Network
  4. Intrusion Prevention
Correct answer: A
Question 2
From a design perspective which two of the following OSPF statements are most relevant? (Choose two)
  1. OSPF stub areas can be thought of as a simple form of summarization
  2. OSPF cannot filter intra-area routes
  3. An ABR can only exist in two areas - the backbone and one adjacent area
  4. Performance issues in the Backbone area can be offset by allowing some traffic to transit a non-backbone area
  5. The size of an area (the LSDB) will be constrained by the size of the IP MTU
Correct answer: AB
Question 3
Which of these Layer 2 access designs does not support VLAN extensions?
  1. FlexLinks
  2. loop-free U
  3. looped square
  4. looped triangle
  5. loop-free inverted U
Correct answer: B
Question 4
Which QoS mechanism uses RSVP?
  1. IntServ
  2. DiffServ
  3. CoS
  4. ToS
Correct answer: A
Question 5
Which of the following is true concerning best design practices at the switched Access layer of the traditional layer2 Enterprise Campus Network?
  1. Cisco NSF with SSO and redundant supervisors has the most impact on the campus in the Access layer
  2. Provide host-level redundancy by connecting each end device to 2 separate Access switches
  3. Offer default gateway redundancy by using dual connections from Access switches to redundant Distribution layer switches using a FHRP
  4. Include a link between two Access switches to support summarization of routing information from the Access to the Distribution layer
Correct answer: A
Question 6
Which two features are from a scalable cluster design utilizing Cisco ASA firewalls? (Choose two.)
  1. Each cluster supports up to 10 ASA devices.
  2. Each member of the cluster can forward every traffic flow.
  3. The ASA cluster actively load balances traffic flows.
  4. The design supports up to 1 Terabyte of aggregate traffic.
  5. The design supports up to 100 Gbps of aggregate traffic.
Correct answer: BE
Question 7
What are two methods of ensuring that the multicast RPF check passes without changing the unicast routing table? (Choose two.)
  1. disabling the interface of the router back to the multicast source
  2. disabling BGP routing protocol
  3. implementing MBGP
  4. implementing OSPF routing protocol
  5. implementing static mroutes
Correct answer: AE
Question 8
Which two of these are correct regarding the recommended practice for distribution layer design? (Choose two.)
  1. use a redundant link to the core
  2. use a Layer 2 link between distribution switches
  3. never use a redundant link to the core because of convergence issues
  4. use a Layer 3 link between distribution switches with route summarization
  5. use a Layer 3 link between distribution switches without route summarization
Correct answer: AD
Question 9
Which two design concerns must be addressed when designing a multicast implementation? (Choose two.)
  1. only the low-order 23 bits of the MAC address are used to map IP addresses
  2. only the low-order 24 bits of the MAC address are used to map IP addresses
  3. only the high-order 23 bits of the MAC address are used to map IP addresses
  4. only the low-order 23 bits of the IP address are used to map MAC addresses
  5. the 0x01004f MAC address prefix is used for mapping IP addresses to MAC addresses
  6. the 0x01005e MAC address prefix is used for mapping IP addresses to MAC addresses
Correct answer: AF
Question 10
Which option is correct when using Virtual Switching System to combine two physical switches into one logical switch?
  1. Both control planes forward traffic simultaneously.
  2. Only one control plane is active, while the other control plane is in standby.
  3. Only one data plane forwards traffic, while the other data plane is in standby.
  4. Control planes are combined into one virtual control plane.
Correct answer: D
Question 11
Which virtualization technology uses Layer 3 BFD to detect network failures between network devices?
  1. VTP
  2. VSS
  3. vPC
  4. Cisco Fabric Path
Correct answer: D
