NEW QUESTION 2
An engineer chose to design an architecture where distribution switches are in VSS and are connected to access switches using Multichassis Etherchannel. What is the resulting topology?

• A. Looped
• B. Ring
• C. Hybrid
• D. Star

Answer: D

NEW QUESTION 3
An engineer is considering uplink bandwidth over-subscription in a Layer 3 network design. Which option is
the Cisco recommended over-subscription ratio for uplinks between the distribution and core layers?

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

Answer: B

Explanation: Network oversubscription refers to a point of bandwidth consolidation where the ingress bandwidth is greater than the egress bandwidth. For example, at an ISL uplink from an edge layer switch to a core, the oversubscription of the ISL is typically on the order of 7:1 or greater. In a single director fabric, the fan-out
ratio of server to storage subsystem ports is directly related to the network oversubscription and is typically on the order of 10:1 or higher. Network oversubscription is normal and unavoidable-it is a direct by product of the primary purpose for deploying a SAN. An important characteristic of the network related to oversubscription is its ability to fairly allocate its bandwidth resources among all clients of the SAN.

NEW QUESTION 4
A link state routing protocol wants to connect tow separate domains, what should be configured (it's a question about IS-IS)?

• A. Level 1 router
• B. Level 1 router interface
• C. Level 2 router interface
• D. Level 2 router

Answer: D

NEW QUESTION 5
An engineer is designing a multitenant network that requires separate management access and must share a single physical firewall. Which two features support this design? (Choose two)

• A. Site-to-Site VPN
• B. dynamic routing protocols
• C. multicast routing
• D. threat detection
• E. quality of service
• F. unified communications

Answer: AB

Explanation: This one is a little bit trickier, separate management access means the multi-context mode https://www.cisco.com/c/en/us/td/docs/security/asa/asa96/configuration/general/asa-96-general-config/hacontex pdf
Page 14 of Guidelines for Multiple Context Mode lists unsupported features, after you cross the unsupported features out - you are left with what works on a multi-context mode firewall

NEW QUESTION 6

• A. In Bidirectional PIM, the RP IP address does not need to be a router.
• B. Bidirectional PIM is deigned to be used for one-to-many applications.
• C. In Bidirectional PIM, the RP IP address can be shared with any other router interface.
• D. ACisco router cannot support all three PIM modes simultaneously.
• E. Membership to be bidirectional group is signaled via explicit join messages.

Answer: CD
