NEW QUESTION # 11
Refer to the exhibit.
Which Cisco lKEv2 configuration brings up the IPsec tunnel between the remote office router and the AWS virtual private gateway?
- A.
- B.
- C.
Answer: C
Explanation:
Option C is the correct answer because it configures the IKEv2 profile with the correct match identity, authentication, and keyring parameters. It also configures the IPsecprofile with the correct transform set and lifetime parameters. Option A is incorrect because it does not specify the match identity remote address in the IKEv2 profile, which is required to match the AWS virtual private gateway IP address. Option B is incorrect because it does not specify the authentication pre-share in the IKEv2 profile, which is required to authenticate the IKEv2 peers using a pre-shared key. Option C also matches the configuration example provided by AWS1 and Cisco2 for setting up an IKEv2 IPsec site-to-site VPN between a Cisco IOS-XE router and an AWS virtual private gateway.

NEW QUESTION # 12
A company with multiple branch offices wants a suitable connectivity model to meet these network architecture requirements:
* high availability
* quality of service (QoS)
* multihoming
* specific routing needs
Which connectivity model meets these requirements?
- A. hybrid topology that combines MPLS and SD-WAN
- B. hub-and-spoke topology using MPLS with static routing and dedicated bandwidth for QoS
- C. fully meshed topology with SD-WAN technology using dynamic routing and prioritized traffic for QoS
- D. star topology with internet-based VPN connections and BGP for routing
Answer: C
Explanation:
A fully meshed topology with SD-WAN technology using dynamic routing and prioritized traffic for QoS meets the network architecture requirements of the company. A fully meshed topology provides high availability by eliminating single points of failure and allowing multiple paths between branch offices.
SD-WAN technology enables multihoming by supporting multiple transport options, such as MPLS, internet, LTE, etc. SD-WAN also provides QoS by applying policies to prioritize traffic based on application, user, or network conditions. Dynamic routing allows the SD-WAN solution to adapt to changing network conditions and optimize the path selection for each traffic type. A fully meshed topology with SD-WAN technology can also support specific routing needs, such as segment routing, policy-based routing, or application-aware routing. References:

NEW QUESTION # 15
Refer to the exhibit.
A company uses Cisco SD-WAN in the data center. All devices have the default configuration. An engineer attempts to add a new centralized control policy in Cisco vManage but receives an error message. What is the problem?
- A. Site-list "All-Site" should be configured with a new match sequence that is lower than the sequence for site-list "Hub*.
- B. The policy for "Hub" should be applied in the outbound direction, and the policy for "All-Site" should be applied inbound.
- C. Apply an additional outbound control policy to override the site ID overlaps.
- D. A centralized control policy is already applied to the specific site ID and direction
Answer: A
Explanation:
The problem is that the site-list "All-Site" has a higher match sequence than the site-list "Hub", which means that the policy for "All-Site" will take precedence over the policy for "Hub" for any site that belongs to both lists. This creates a conflict and prevents the engineer from adding a new centralized control policy in Cisco vManage. To resolve this issue, the site-list "All-Site" should be configured with a new match sequence that is lower than the sequence for site-list "Hub", so that the policy for "Hub" will be applied first and then the policy for "All-Site" will be applied only to the remaining sites that are not in the "Hub" list.

Which method is used to create authorization boundary diagrams (ABDs)?
- A. identify only interconnected systems that are FedRAMP-authorized
- B. show all networks in CIDR notation only
- C. identify all tools as either external or internal to the boundary
- D. show only minor or small upgrade level software components
Answer: C
Explanation:
According to the FedRAMP Authorization Boundary Guidance document1, the method used to create authorization boundary diagrams (ABDs) is to identify all tools as either external orinternal to the boundary.
The ABD is a visual representation of the components that make up the authorization boundary, which includes all technologies, external and internal services, and leveraged systems and accounts for all federal information, data, and metadata that a Cloud Service Offering (CSO) is responsible for. The ABD should illustrate a CSP's scope of control over the system and show components or services that are leveraged from external services or controlled by the customer1. The other options are incorrect because they do not capture the full scope and details of the authorization boundary as required by FedRAMP.

NEW QUESTION # 20
An engineer must configure an IPsec tunnel to the cloud VPN gateway. Which Two actions send traffic into the tunnel? (Choose two.)
- A. Configure a static route.
- B. Configure an IPsec profile and match the remote peer IP address.
- C. Configure a local policy in Cisco vManage.
- D. Configure policy-based routing.
- E. Configure access lists that match the interesting user traffic.
Answer: D,E
Explanation:
To send traffic into an IPsec tunnel to the cloud VPN gateway, the engineer must configure two actions:
Configure access lists that match the interesting user traffic. This is the traffic that needs to be encrypted and sent over the IPsec tunnel. The access lists are applied to the crypto map that defines the IPsec parameters for the tunnel.
Configure policy-based routing (PBR). This is a technique that allows the engineer to override the routing table and forward packets based on a defined policy. PBR can be used to send specific traffic to the IPsec tunnel interface, regardless of the destination IP address. This is useful when the cloud VPN gateway has a dynamic IP address or when multiple cloud VPN gateways are available for load balancing or redundancy. References:

NEW QUESTION # 22 
Refer to the exhibits. An engineer must redistribute OSPF internal routes into BGP to connect an on-premises network to a cloud provider without introducing extra routes. Which two commands must be configured on router R2? (Choose two.)
- A. redistribute ospf 1 match internal external
- B. redistribute bgp 100
- C. router ospf 1
- D. router bgp 100
- E. redistribute ospf 1
Answer: A,D
Explanation:
To redistribute OSPF internal routes into BGP, the engineer needs to configure two commands on router R2.
The first command is router bgp 100, which enables BGP routing process and specifies the autonomous system number of 100. The second command is redistribute ospf 1 match internal external, which redistributes the routes from OSPF process 1 into BGP, and matches both internal and external OSPF routes. This way, the engineer can avoid introducing extra routes that are not part of OSPF process 1, such as the default route or the connected routes.
