NEW QUESTION # 20
A company has multiple branch offices across different geographic locations and a centralized data center. The company plans to migrate Its critical business applications to the public cloud infrastructure that is hosted in Microsoft Azure. The company requires high availability, redundancy, and low latency for its business applications. Which connectivity model meets these requirements?
- A. ExpressRoute with private peering using SDCI
- B. hybrid connectivity with SD-WAN
- C. AWS Direct Connect with dedicated connections
- D. site-to-site VPN with Azure VPN gateway
Answer: A
Explanation:
The connectivity model that meets the requirements of high availability, redundancy, and low latency for the company's business applications is ExpressRoute with private peering using SDCI.
ExpressRoute is a service that provides a dedicated, private, and high-bandwidth connection between the customer's on-premises network and Microsoft Azure cloud network1.
Private peering is a type of ExpressRoute circuit that allows the customer to access Azure services that are hosted in a virtual network, such as virtual machines, storage, and databases2.
SDCI (Secure Data Center Interconnect) is a Cisco solution that enables secure and scalable connectivity between multiple data centers and cloud providers, using technologies such as MPLS, IPsec, and SD-WAN3.
By using ExpressRoute with private peering and SDCI, the company can achieve the following benefits:
High availability: ExpressRoute circuits are redundant and resilient, and can be configured with multiple service providers and locations for failover and load balancing1. SDCI also provides high availability by using dynamic routing protocols and encryption mechanisms to ensure optimal and secure path selection3.
Redundancy: ExpressRoute circuits can be paired together to form a redundant connection between the customer's network and Azure4. SDCI also supports redundancy by allowing multiple connections between data centers and cloud providers, using different transport technologies and service levels3.
Low latency: ExpressRoute circuits offer lower latency than public internet connections, as they bypass the congestion and variability of the internet1. SDCI also reduces latency by using MPLS and SD-WAN to optimize the performance and quality of service for the traffic between data centers and cloud providers3.

NEW QUESTION # 21
An engineer must edit the settings of a site-to-site IPsec VPN connection between an on-premises Cisco IOS XE router and Amazon Web Services (AWS). IPsec must be configured to support multiple peers and failover after 120 seconds of idle time on the first entry of the crypto map named Cisco. Drag and drop the commands from the left onto the order on the right.
Answer:
Explanation:
Explanation:
Step 1 = crypto map cisco 1 ipsec-isakmp Step 2 = set peer 192.168.10.1 default Step 3 = set peer
192.168.20.1 Step 4 = set security-association idle-time 120 default
The process of editing the settings of a site-to-site IPsec VPN connection between an on-premises Cisco IOS XE router and Amazon Web Services (AWS), and configuring IPsec to support multiple peers and failover after 120 seconds of idle time on the first entry of the crypto map named Cisco involves several steps123456.
crypto map cisco 1 ipsec-isakmp: This command is used to create a new entry in the crypto map named
"cisco". The "1" is the sequence number of the entry, and "ipsec-isakmp" specifies that the IPSec security associations (SAs) should be established using the Internet Key Exchange (IKE) protocol13.
set peer 192.168.10.1 default: This command is used to specify the IP address of the default peer for the crypto map entry. In this case, the default peer is at IP address 192.168.10.115.
set peer 192.168.20.1: This command is used to add an additional peer to the crypto map entry. In this case, the additional peer is at IP address 192.168.20.1. This allows the IPsec VPN to support multiple peers56.
set security-association idle-time 120 default: This command is used to set the idle time for the security association. If no traffic is detected over the VPN for the specified idle time (in this case, 120 seconds), the security association is deleted, and the VPN connection fails over to the next peer46.

NEW QUESTION # 22
Refer to the exhibits.
While troubleshooting, a network engineer discovers that the backup path fails between ASBR3 and ASBR4 for traffic between BGP AS6000 and BGP AS6500 when the connection between ASBR1 and ASBR2 goes down. The following configurations were performed on ASBR1:
Which command is missing?
- A. bgp additional-paths select
- B. bgp advertise-best-external
- C. redistribute static
- D. bgp additional-paths Install
Answer: B
Explanation:
The bgp advertise-best-external command is used to enable the advertisement of the best external path to internal BGP peers. This command is useful when there are multiple exit points from the local AS to other ASes, and the local AS wants to use the closest exit point for each destination. By default, BGP only advertises the best path to its peers, and the best path is usually the one with the lowest IGP metric to the next hop. However, this may not be the optimal path for traffic leaving the local AS, as it may result in suboptimal hot-potato routing or MED oscillations. The bgp advertise-best-external command allows BGP to advertise the best external path, which is the path with the lowest MED among the paths from different neighboring ASes, in addition to the best path. This way, the internal BGP peers can choose the best exit point based on the MED value, rather than the IGP metric. In this scenario, ASBR1 is configured to receive additional paths from ASBR2, which is a route reflector. ASBR2 receivestwo paths for the same prefix from AS6500, one from ASBR3 and one from ASBR4. ASBR2 selects the best path based on the IGP metric to the next hop, and advertises it to ASBR1. However, this path may not be the best external path, as it may have a higher MED value than the other path. If the connection between ASBR1 and ASBR2 goes down, ASBR1 will not have any backup path to reach AS6500, as it does not know the other path from ASBR4. To prevent this situation, ASBR1 should be configured with the bgp advertise-best-external command, so that it can receive the best external path from ASBR2, along with the best path. This way, ASBR1 will have a backup path to reach AS6500, in case the primary path fails. References := IP Routing: BGP Configuration Guide - BGP Additional Paths ... - Cisco, BGP Additional Paths
NEW QUESTION # 23
Refer to the exhibit.
While troubleshooting an IPsec connection between a Cisco WAN edge router and an Amazon Web Services (AWS) endpoint, a network engineer observes that the security association status is active, but no traffic flows between the devices What is the problem?
- A. identity mismatch
- B. IKE version mismatch
- C. wrong ISAKMP policy
- D. wrong encryption
Answer: A
Explanation:
An identity mismatch occurs when the local and remote identities configured on the IPsec peers do not match.
This can prevent the establishment of an IPsec tunnel or cause traffic to be dropped by the IPsec policy. In this case, the network engineer should verify that the local and remote identities configured on the Cisco WAN edge router and the AWS endpoint match the values expected by each peer. The identities can be an IP address, a fully qualified domain name (FQDN), or a distinguished name (DN). The identities are exchanged during the IKE phase 1 negotiation and are used to authenticate the peers. If the identities do not match, the peers will reject the IKE proposal and the IPsec tunnel will not be established or will be torn down.

An engineer must enable the OMP advertisement of BGP routes for a specific VRF instance on a Cisco IOS XE SD-WAN device. What should be configured after the global address-family ipv4 is configured?
- A. Enable bgp advertisement.
- B. Enter sdwan mode.
- C. Disable bgp advertisement.
- D. Set the VRF-specific route advertisements.
Answer: A
Explanation:
To enable the OMP advertisement of BGP routes for a specific VRF instance on a Cisco IOS XE SD-WAN device, the engineer must first configure the global address-family ipv4 and then enable bgp advertisement under the vrf definition. This will allow the device to advertise the BGP routes learned from the cloud provider to the OMP control plane, which will then distribute them to the other SD-WAN devices in the overlay network1 References := 1: Designing and Implementing Cloud Connectivity (ENCC) v1.0, Module 3: Implementing Cloud Connectivity, Lesson 3: Configuring IPsec VPN from Cisco IOS XE to AWS, Topic: Configuring BGP on the Cisco IOS XE Device, Page 3-24.

Refer to the exhibits. An engineer must redistribute IBGP routes into OSPF to connect an on-premises network to a cloud provider. Which command must be configured on router R2?
- A. redistribute bgp 100 subnets
- B. redistribute ospf 1
- C. redistribute bgp 100 ospf 1
- D. bgp redistrlbute-lnternal
Answer: C
Explanation:
This command redistributes the routes learned from BGP AS100 into OSPF Area 1, which allows router R2 to advertise those routes to router R1 and connect the on-premises network to the cloud provider. The other options are incorrect because they either redistribute the wrong routes or use the wrong syntax5 .

NEW QUESTION # 27
Which approach does a centralized internet gateway use to provide connectivity to SaaS applications?
- A. VPN connections are used to provide secure access to SaaS applications from the on-premises infrastructure.
- B. Internet traffic from the on-premises infrastructure is routed through a centralized gateway that provides access controls for SaaS applications.
- C. A dedicated, private connection is established between the on-premises infrastructure and the SaaS provider data center using colocation services.
- D. A cloud-based proxy server routes traffic from the on-premises infrastructure to the SaaS provider data center.
Answer: B
Explanation:
A centralized internet gateway is a network design that routes all internet-bound traffic from the on-premises infrastructure through a single point of egress, typically located at the data center or a regional hub1. This approach allows the enterprise to apply consistent security policies and access controls for SaaS applications, as well as optimize the bandwidth utilization and performance of the WAN links2. A centralized internet gateway can use various technologies to provide connectivity to SaaS applications, such as proxy servers, firewalls, web filters, and WAN optimizers3. However, a cloud-based proxy server (option A) is not a part of the centralized internet gateway, but rather a separate service that can be used to route traffic from the on-premises infrastructure to the SaaS provider data center4. VPN connections (option C) and dedicated, private connections (option D) are also not related to the centralized internet gateway, but rather alternative ways of providing secure and reliable access to SaaS applications from the on-premises infrastructure5. Therefore, the correct answer is option B, which describes the basic function of a centralized internet gateway. References := 1: Designing and Implementing Cloud Connectivity (ENCC) v1.0, Module 1:

An engineer must configure cloud connectivity with Cisco Umbrella Secure Internet Gateway (SIG) in active/backup mode. The engineer already configured the SIG Credentials and SIG Feature Templates. Drag and drop the steps from the left onto the order on the right to complete the configuration.
Answer:
Explanation:
Explanation:
The configuration of cloud connectivity with Cisco Umbrella Secure Internet Gateway (SIG) in active/backup mode involves several steps. After configuring the SIG Credentials and SIG Feature Templates, the engineer must:
Select the SIG provider for the primary tunnel: This is the first step in setting up the active/backup mode. The primary tunnel is the main connection path for the cloud connectivity.
Add the secondary tunnel: The secondary tunnel serves as a backup in case the primary tunnel fails. It ensures that the cloud connectivity remains uninterrupted even if there are issues with the primary tunnel.
Create one high-availability pair using primary and secondary tunnels: This step involves pairing the primary and secondary tunnels to create a high-availability pair. Thisensures that the cloud connectivity will switch over to the secondary tunnel seamlessly if the primary tunnel fails.
Edit the service-side VPN template to inject a service route: The final step involves modifying the VPN template on the service side to include a service route. This ensures that the traffic is correctly routed through the primary or secondary tunnel as needed.

NEW QUESTION # 29
Which method is used to create authorization boundary diagrams (ABDs)?
- A. identify all tools as either external or internal to the boundary
- B. identify only interconnected systems that are FedRAMP-authorized
- C. show all networks in CIDR notation only
- D. show only minor or small upgrade level software components
Answer: A
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 # 32
A cloud engineer is setting up a new set of nodes in the AWS EKS cluster to manage database integration with Mongo Atlas. The engineer set up security to Mongo but now wants to ensure that the nodes are also secure on the network side. Which feature in AWS should the engineer use?
- A. tagging
- B. security groups
- C. EC2 Trust Lock
- D. key pairs
Answer: B
Explanation:
Security groups are a feature in AWS that allow you to control the inbound and outbound traffic to your instances. They act as a virtual firewall that can filter the traffic based on the source, destination, protocol, and port. You can assign one or more security groups to your instances, and each security group can have multiple rules. Security groups are stateful, meaning that they automatically allow the response traffic for any allowed inbound traffic, and vice versa. Security groups are essential for securing your nodes in the AWS EKS cluster, as they can prevent unauthorized access to your Mongo Atlas database or other resources. You can also use security groups to isolate your nodes from other instances in the same VPC or subnet, or to allow communication between nodes in different clusters or regions.

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.
