NEW QUESTION 3
Which Cisco NAC Appliance design is the most scalable in large Layer 2-to-distribution implementation?

  • A. Layer 2 out-of-band
  • B. Layer 2 in-band
  • C. Layer 3 out-of-band
  • D. Layer 3 in-band

Answer: B

Explanation: https://www.safaribooksonline.com/library/view/foundation-learning-guide/9780132652933/ch08.html "Layer 2 In-Band Designs The Layer 2 in-band topology is the most common deployment option.
[...]
This is the most scalable design in large L2-to-distribution environments, because this design can be transparently implemented in the existing network supporting multiple access layer switches. It supports all
network infrastructure equipment. The Cisco NAS supports per-user ACLs."

NEW QUESTION 4
An engineer want to ensure that of the PEs are discovery in VPLS discover PS. use signaling and access to across PE router without having manually provision VPLS neighbors, What solution must be implemented?

  • A. BGP autodiscovery with BGP signalling
  • B. BGP autodiscovery with LDP signalling
  • C. H-VPLS with PW-access
  • D. BGP-based VPLS autodiscovery

Answer: D

Explanation: https://www.cisco.com/c/en/us/td/docs/ios/12_2sr/12_2srb/feature/guide/fs_vpls.html and

  • A. GLBP
  • B. HSRP
  • C. VRRP
  • D. VSS

Answer: A

NEW QUESTION 6

  • A. 3 to 1
  • B. 4 to 1
  • C. 6 to 1
  • D. 8 to 1

Answer: B

NEW QUESTION 7

  • A. Stateful firewall
  • B. uRPF
  • C. Connections limits and timeouts
  • D. Access-lists

Answer: C

NEW QUESTION 8
A company have single ASA hardware box and they need to separate company departments in way that they can apply different rules on them, ACL, NAT, and so on... Which mode is needed?

  • A. routed mode
  • B. transparent mode
  • C. multiple context mode
  • D. active failover mode

Answer: C

NEW QUESTION 9
Which two ways to support secure transport of multicast traffic are true? (Choose two.)

  • A. Use spoke-to-spoke design.
  • B. Use IPsec over GRE tunnel.
  • C. Use GET VPN.
  • D. Use NBMA instead of broadcast.
  • E. Disable encryption for multicast traffic.

Answer: BC

Explanation: GET VPN = Group Encrypted Transport VPN. It is tunnel-less and can support multicast traffic

NEW QUESTION 10
Which two options describe how Taboo contracts differ from regular contracts in Cisco ACI? (Choose two) (E)

  • A. Taboo contract entries are looked up with higher priority than entries in regular contracts
  • B. Taboo contract entries are looked up with lower priority than entries in regular contracts.
  • C. They are not associated with one EPG
  • D. They are not associated with EPGs
  • E. Taboo contract entries are looked up based on administrator configured priority
  • F. They are associated with pair of EPGs

Answer: AF

Explanation: There may be times when the ACI administrator might need to deny traffic that is allowed by another contract. Taboos are a special type of contract that an ACI administrator can use to deny specific traffic that would otherwise be allowed by another contract. Taboos can be used to drop traffic matching a pattern (any EPG, a specific EPG, matching a filter, and so forth). Taboo rules are applied in the hardware before the rules of regular contracts are applied. Taboo contracts are not recommended as part of the ACI best practices but they can be used to transition from traditional networking to ACI. To imitate the traditional networking concepts, an "allow-all-traffic" contract can be applied, with taboo contracts configured to restrict certain types of traffic."

NEW QUESTION 11
What is the result of a successful RPF check?

  • A. Packet is dropped because it arrived on the interface that used to forward the packet back to source.
  • B. Packet is dropped because it arrived on the interface that used to forward the packet back to destination.
  • C. Packet is forwarded because it arrived on the interface that used to forward the packet back to destination
  • D. Packet is forwarded because it arrived on the interface that used to forward the packet back to source

Answer: D

NEW QUESTION 12
