Cisco Designing and Implementing Cisco Service Provider Cloud Network Infrastructure Sample Questions (Q39-Q44):

NEW QUESTION # 39

Refer to the exhibit. An engineer must configure an IPsec VPN connection between site 1 and site 2. The indicated configuration was applied to router R1; however, the tunnel fails to come up. Which command must be run on R1 to resolve the issue?

Answer: A

Explanation:
For asite-to-site IPsec VPN, each peer must point to thereachable IP address of the remote VPN endpoint
-that is, the IP address on the WAN/Internet-facing interface of the remote router.
From the diagram:
* R1 outside (toward Internet):192.168.10.1
* R2 outside (toward Internet):192.168.20.2
* Inside LANs:
* Site 1:10.1.0.0/24
* Site 2:10.2.0.0/24
The crypto map on R1 uses:
crypto map mymap 10 ipsec-isakmp
set transform-set myset
match address 101
set peer <REMOTE_PEER_IP>
The <REMOTE_PEER_IP> must be the IP address where R1 can actually reach the IPsec peer, which is R2's Internet-facing interface192.168.20.2.
If the peer were configured with a LAN IP such as 10.2.0.1 (site 2's internal gateway), IKE packets would never reach the remote router because that address is not routable over the Internet.
Therefore, the correct command to bring up the VPN is:
set peer 192.168.20.2
* Option A (10.1.0.1)- local LAN IP (R1's side), not the remote endpoint.
* Option C (192.168.10.1)- R1's own WAN IP, not the remote peer.
* Option D (10.2.0.1)- remote LAN IP, not reachable directly over the Internet.


NEW QUESTION # 40
Troubleshooting ACI involves understanding:

Answer: B


NEW QUESTION # 41
What is Virtualized Architecture primarily used for in the context of IT infrastructure?

Answer: A


NEW QUESTION # 42
What is a benefit of using VXLANs in a cloud-scale environment?

Answer: C

Explanation:
In a cloud-scale or data center-scale environment,Virtual Extensible LAN (VXLAN)is used as anoverlay technologyto transportLayer 2 segments over a Layer 3 underlay network. VXLAN encapsulates Layer 2 Ethernet frames inside UDP/IP packets, allowing broadcast, unknown unicast, and multicast (BUM) traffic and tenant Layer 2 domains to be extended across a routed IP fabric.
Key points aligned with Cisco Service Provider Cloud Infrastructure design principles:
* VXLAN creates aLayer 2 overlay on top of a Layer 3 underlay.
* TheVXLAN Network Identifier (VNI)provides a much larger segmentation space than traditional VLANs, enabling multi-tenancy at cloud scale.
* Because the underlay is pure Layer 3 (IP routed fabric), VXLAN allows you tointerconnect Layer 2 segments between leaf switches or data centers over an IP/MPLS backbonewithout relying on large Layer 2 domains in the physical network.
Why the options evaluate as follows:
* Option A: extends Layer 2 segments across the underlying Layer 3 infrastructure#This is the core benefit of VXLAN in cloud-scale designs. VXLAN encapsulates Layer 2 frames intoIP/UDP headers, allowing isolated Layer 2 segments (per VNI) to be stretched across a routed IP network. This enables:
* Multi-tenant Layer 2 connectivity across a distributed cloud fabric
* Mobility of virtual machines or containers while keeping same IP/MAC addressing
* Use of an IP-based leaf-spine or service provider underlay for scalability and resiliency
* Option B: extends Layer 3 segments across the underlying Layer 2 infrastructure#This is the opposite of what VXLAN does. VXLAN is explicitlyL2-over-L3, not L3-over-L2. Extending pure Layer 3 segments over Layer 2 is not the VXLAN use case.
* Option C: reduces spanning-tree complexity across the Layer 2 infrastructure##(Partially related but not the primary or direct benefit)In modern designs, the underlay isLayer 3 routed, and VXLAN overlays provide logical Layer 2 segments. This designavoids dependence on spanning tree in the fabric, whichindirectlyreduces STP complexity. However, the fundamental, exam-relevant benefit isL2 extension over L3, so C is not the best or most accurate answer compared to A.
* Option D: eliminates the need for a Layer 3 underlay in the service provider infrastructure
#VXLAN absolutelyrequiresan IP (Layer 3) underlay for transport. VXLAN tunnels are built over a routed infrastructure (leaf-spine, MPLS/IP core, etc.). It does not remove the need for Layer 3; it depends on it.


NEW QUESTION # 43

Refer to the exhibit. An engineer is troubleshooting a Cisco NFVI issue where the management node fails to start. Which service must be restarted to resolve the issue?

Answer: B

Explanation:
In Cisco NFVI, themanagement noderelies heavily on Docker containers for:
* NFVIS management functions
* VIM services
* Orchestration components
If the management node fails to start and the system shows:
docker.service: inactive (dead)
...then all Docker-based platform services also fail to start.
The correct recovery action is torestart the Docker engine:
systemctl restart docker
This brings up:
* All NFVI-required Docker containers
* Management services
* REST APIs and cluster components
Why other answers are incorrect:
* docker-kibana# Only affects Kibana logging container
* docker-cobbler# Used for provisioning, not core NFVI management
* kube-apiserver# Part of Kubernetes cluster, but relies on Docker; restarting it won't help until Docker is running Thus, the correct answer isB. docker.
