- C. XHTML
- D. YAML
Answer: D
Explanation:
Comprehensive and Detailed Explanation
Cisco Container Platform (CCP), built on Kubernetes orchestration, usesYAMLfiles for:
* Cluster configuration

NEW QUESTION # 83
How does SR-IOV move data directly to and from the network adapter?
- A. Bypassing the guest operating system
- B. Using the STP PortFast
- C. Using the STP VLAN root
- D. Bypassing the hypervisor
Answer: D
Explanation:
Comprehensive and Detailed Explanation (Cisco NFVI / Virtualization Knowledge) SR-IOV (Single Root I/O Virtualization)allows a VM to access the network interface hardwaredirectly, without going through the hypervisor's virtual switch.
This is achieved by:
* Assigning Virtual Functions (VFs) directly to VMs
* Allowing high-performance, low-latency packet I/O
* Bypassing the hypervisor datapath
Therefore, SR-IOV doesnotbypass the guest OS; it bypasses thehypervisor I/O virtualization layer, delivering near-native performance.
Thus the correct answer isC.
NEW QUESTION # 84
An engineer must design a pay-as-you-go solution for their partners. The solution must allow for rapid deployments, be flexible, and scale resources up or down in a hybrid workplace. What must be used?
- A. Cisco+ Hybrid Cloud for Virtualization
- B. Cisco+ Hybrid Cloud for Bare Metal Compute
- C. Cisco+ Hybrid Cloud for Virtual Desktop Infrastructure
- D. Cisco+ Hybrid Cloud for Service Provider Networking
Answer: C
Explanation:
Comprehensive and Detailed Explanation From Exact Extract from my knowledge of Designing and Implementing Cisco Service Provider Cloud Network Infrastructure Outlines without Any External URL or Links:
Cisco+ Hybrid Cloud is Cisco's as-a-service consumption model that offers pay-as-you-go infrastructure. For ahybrid workplace, the focus is on giving users secure desktop environments from anywhere, with the ability torapidly deployandscale up or downbased on the number of users or partners.
Cisco+Hybrid Cloud for Virtual Desktop Infrastructure (VDI)specifically delivers desktop and app workspaces as an on-demand service. It allows partners to consume desktops elastically, paying for capacity as needed and scaling the underlying compute, storage, and networking without rebuilding the environment.
* Bare Metal Compute and Virtualization offers flexible infrastructure but are aimed at app/workload hosting rather than user desktop workspaces.
* Service Provider Networking addresses network services, not end-user hybrid workplace desktops.
Therefore, for a pay-as-you-go, rapidly deployable, elastic solution in a hybrid workplace,Cisco+ Hybrid Cloud for Virtual Desktop Infrastructureis the correct choice.
NEW QUESTION # 85

- C. Yang models
- D. SNMP
- E. NETCONF
Answer: A,B,E
NEW QUESTION # 86
Which command must be run on a Cisco IOS device to configure six parallel iBGP and eBGP routes that can be installed into a routing table?
- A. maximum paths bgp 6
- B. maximum-paths eibgp 6
- C. maximum paths bgp routers 6
- D. multipath eibgp 6
Answer: A
Explanation:
Comprehensive and Detailed Explanation From Cisco SP Core Optimization Knowledge Cisco IOS supportsBGP Multipathfor installing multiple equal-cost BGP routes (both iBGP and eBGP) into the routing table. The correct global BGP command syntax to set the number of allowable parallel BGP paths is:
maximum-paths <number>
For BGP specifically, the form is:
maximum-paths bgp <number>
This enables the router to install up to the specified number of equal-cost BGP routes (iBGP and eBGP) into the RIB and then potentially into the FIB.
Setting:
maximum-paths bgp 6
allowssixparallel ECMP paths learned via BGP-this matches the requirement in the question.
Why the other options are incorrect
* B. multipath eibgp 6Not a valid Cisco IOS command.
* C. maximum paths bgp routers 6Invalid syntax.
* D. maximum-paths eibgp 6The correct keyword isbgp, noteibgp.Cisco does not use "eibgp" in this context; IOS supports BGP multipath across iBGP/eBGP automatically when configured under maximum-paths bgp.
NEW QUESTION # 87
An engineer attempts to kill a NETCONF session. The session ID is equal to the current session. What is the effect of this action?
- A. The configuration is saved, and the current user is logged out.
- B. The configuration is removed, and the current user is logged out.
- C. An invalid-value error is returned, and the current user is not logged out.
- D. The session is terminated, and all the connected users are logged out.
Answer: C
Explanation:
NETCONF rules state:
* A user cannot terminatetheir own active session.
* Attempting to kill the same session returnsinvalid-valueerror.
* The session continues running normally.
Thus:
* No logout
* No termination
* No configuration impact
Therefore,Ais correct.
NEW QUESTION # 88
MPLS is preferred over traditional routing because it:
- A. Increases the complexity of the network
- B. Can only be used for small-scale networks
- C. Uses longer paths for data transmission
- D. Provides more reliable and efficient data packet delivery
Answer: D
NEW QUESTION # 89 
Refer to the exhibit. An engineer is troubleshooting an issue where Cisco switch Switch_A fails to establish OTV connectivity to Cisco switch Switch_C. What is the cause of the issue?
- A. The control group must be 232.1.1.0.
- B. The join interface must be g1/0.
- C. The join interface must be e1/1.
- D. The broadcast group must be 232.1.1.0.
Answer: B
Explanation:
In Cisco Overlay Transport Virtualization (OTV), thejoin interfaceis the Layer 3 interface that connects the edge device to thetransport network(the routed core / WAN) where multicast groups (control, data, broadcast) are reachable.
From the topology:
* Interfaceg1/0on Switch_A is connected to the routed 20.20.20.0/30 link toward Switch_C (the transport
/ WAN).
* Interfaceg1/1is a trunk toward Switch_B and carries extended VLANs (101, 111), so it belongs to the internal site-facing side, not the transport.
In the show otv output, the join interface is incorrectly configured asg1/1 (20.20.20.2), which is an internal trunk and not the correct routed interface to the OTV transport network. Because the join interface does not face the multicast-enabled transport, OTV cannot establish adjacency and the VPN state remains DOWN.
Correct configuration should use:
otv join-interface GigabitEthernet1/0
Options A and C about group addresses are not the issue; addresses shown (224.x for control/broadcast and
232.x for data group range) are valid multicast ranges. Option D (e1/1) is also an internal access/trunk interface and not the WAN transport interface.
NEW QUESTION # 90
The use of pseudowires in DCI solutions is primarily to:
- A. Provide layer 3 connectivity over a layer 2 network
- B. Reduce the overall security of the data being transmitted
- C. Simulate a wire-like connection over a packet-switched network
- D. Create a physical connection between two points
Answer: C
NEW QUESTION # 91
What is a benefit of a carrier-neutral data center?
- A. Avoidance of a price lock-in
- B. Lower electrical costs
- C. Path diversity on multiple carriers
- D. Reduction in foot traffic
Answer: C
Explanation:
Carrier-neutral facilities allow customers to connect tomultiple telecom carriers, providing:
* Physical path diversity
* Redundancy
* Competitive options
* High availability for interconnects
Thus,path diversity on multiple carriersis the primary benefit.

NEW QUESTION # 94
An engineer must implement a public cloud solution that enables a company to place all its infrastructureand its end-user applications in the cloud, eliminating the need for software application management and maintenance. Which cloud service model must be used?
- A. FaaS
- B. IaaS
- C. SaaS
- D. PaaS
Answer: C
Explanation:
Comprehensive and Detailed Explanation (Cisco Cloud Model Knowledge)
The requirement states:
* All infrastructure in the cloud
* All applications delivered from the cloud
* No software management
* No maintenance by the customer
This matchesSoftware as a Service (SaaS).
SaaS provides:
* Fully managed applications
* No patching, upkeep, installation, or infrastructure maintenance
* End-to-end cloud delivery
PaaS and IaaS still require some software/application management.
FaaS is event-driven serverless compute, not full application hosting.
Therefore, the correct answer isA. SaaS.

- A. The availability and performance requirements of the application
- B. The scalability and flexibility of MPLS/segment routing
- C. The cost and complexity of IPsec VPNs only
- D. The exclusive use of Direct Connect for all scenarios
Answer: A
