NEW QUESTION # 15
What is the role of service providers to establish private connectivity between on-premises networks and Google Cloud resources?
- A. enable intelligent routing and dynamic path selection using software-defined networking
- B. provide end-to-end encryption for data transmission using native IPsec
- C. facilitate direct, dedicated network connections through Google Cloud Interconnect
- D. accelerate content delivery through integration with Google Cloud CDN
Answer: C
Explanation:
The role of service providers to establish private connectivity between on-premises networks and Google Cloud resources is to facilitate direct, dedicated network connections through Google Cloud Interconnect.
Google Cloud Interconnect is a service that allows customers to connect their on-premises networks to Google Cloud through a service provider partner. This provides low latency, high bandwidth, and secure connectivity to Google Cloud services, such as Google Compute Engine, Google Cloud Storage, and Google BigQuery.
Google Cloud Interconnect also supports hybrid cloud scenarios, such as extending on-premises networks to Google Cloud regions, or connecting multiple Google Cloud regions together. Google Cloud Interconnect offers two types of connections: Dedicated Interconnect and Partner Interconnect. Dedicated Interconnect provides physical connections between the customer's network and Google's network at a Google Cloud Interconnect location. Partner Interconnect provides virtual connections between the customer's network and Google's network through a supported service provider partner. Both types of connections use VLAN attachments to establish private connectivity to Google Cloud Virtual Private Cloud (VPC) networks. References:

NEW QUESTION # 16
Refer to the exhibit.
Refer to the exhibits. An engineer troubleshoots a Cisco SD-WAN connectivity issue between an on-premises data center WAN Edge and a public cloud provider WAN Edge. The engineer discovers that BFD is Dapping on vEdge1. What is the problem?
- A. The control plane deleted the BFD session.
- B. The remote Edge device has a duplicate IP address.
- C. The remote Edge device BFD is down.
- D. The remote Edgedevice failed to respond BFD keepalives.
Answer: D
Explanation:
BFD (Bidirectional Forwarding Detection) is a protocol that detects failures in the overlay tunnel between Cisco SD-WAN devices. BFD packets are sent and received periodically by each device to check the liveliness and quality of the connection. If a device does not receive a BFD packet from its peer within a specified timeout interval, itconsiders the peer to be unreachable and reports a BFD down event. This event triggers a control connection state change and a possible route change in the SD-WAN fabric.
In this scenario, the engineer discovers that BFD is flapping on vEdge1, which means that the BFD session between vEdge1 and the remote Edge device is going up and down repeatedly. This indicates a connectivity issue between the two devices, such as network congestion, packet loss, or misconfiguration. The most likely cause of the problem is that the remote Edge device failed to respond BFD keepalives within the timeout interval, which resulted in a BFD timeout event on vEdge1. This event caused vEdge1 to mark the remote Edge device as down and notify the control plane. The control plane then tried to establish a new BFD session with the remote Edge device, which may have succeeded or failed depending on the network condition. This cycle of BFD session creation and deletion caused the BFD flapping on vEdge1.
The other options are less likely to be the cause of the problem. Option A is incorrect because if the remote Edge device BFD was down, vEdge1 would not receive any BFD packets from it and would not flap. Option C is incorrect because if the remote Edge device had a duplicate IP address, vEdge1 would not be able to establish a BFD session with it in the first place. Option D is incorrect because the control plane does not delete the BFD session unless there is a configuration change or a port-hop event on the device.

NEW QUESTION # 17
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. Enter sdwan mode.
- B. Enable bgp advertisement.
- C. Disable bgp advertisement.
- D. Set the VRF-specific route advertisements.
Answer: B
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.
NEW QUESTION # 18
An engineer must use Cisco vManage to configure an application-aware routing policy Drag and drop the steps from the left onto the order on the right to complete the configuration.
Answer:
Explanation:
Explanation:
Step 1 = Create the groups of interest. Step 2 = Configure the topology. Step 3 = Create the application-aware routing policy. Step 4 = Apply the application-aware routing policy to a specific VPN and sites.
The process of configuring an application-aware routing policy in Cisco vManage involves several steps12.
Create the groups of interest: This is the first step where you define the applications or groups that the policy will affect1.
Configure the topology: This involves setting up the network topology that the policy will operate within1.
Create the application-aware routing policy: After setting up the groups and topology, you then create the application-aware routing policy. This policy tracks network and path characteristics of the data plane tunnels between Cisco SD-WAN devices and uses the collected information to compute optimal paths for data traffic31.
Apply the application-aware routing policy to a specific VPN and sites: Finally, the created policy is applied to a specific VPN and sites. This allows the policy to affect the desired network traffic1.

NEW QUESTION # 19
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 # 20 
Refer to the exhibits. An engineer must redistribute only the 10.0.10.0/24 network into BGP to connect an on-premises network to a public cloud provider. These routes are currently redistributed:
Which command is missing on router R2?
- A. redistribute ospf 1 match internal
- B. neighbor 10.0.10.0/24 remote-as 100
- C. neighbor 10.0.10.2 remote-as 100
- D. redistribute ospf 1 match external
Answer: D
Explanation:
The command redistribute ospf 1 match external is missing on router R2. This command is needed to redistribute only the external OSPF routes into BGP. The external OSPF routes are those that are learned from another routing protocol or redistributed into OSPF. In this case, the 10.0.10.0/24 network is an external OSPF route, as it is redistributed from EIGRP into OSPF on router R1. The other commands are either already present or not relevant for this scenario.

NEW QUESTION # 21 
Refer to the exhibit. An engineer successfully brings up the site-to-site VPN tunnel between the remote office and the AWS virtual private gateway, and the site-to-site routing works correctly. However, the end-to-end ping between the office user PC and the AWS EC2 instance is not working. Which two actions diagnose the loss of connectivity? (Choose two.)
- A. Check the network security group rules on the host VNET.
- B. Check the IPsec SA counters.
- C. Check the security group rules for the host VPC.
- D. On the Cisco VPN router, configure the IPsec SA to allow ping packets.
- E. On the AWS private virtual gateway, configure the IPsec SA to allow ping packets.
Answer: B,C
Explanation:
The end-to-end ping between the office user PC and the AWS EC2 instance is not working because either the security group rules for the host VPC are blocking the ICMP traffic or the IPsec SA counters are showing errors or drops. To diagnose the loss of connectivity, the engineer should check both the security group rules and the IPsec SA counters. The network security group rules on the host VNET are not relevant because they apply to Azure, not AWS. The IPsec SA configuration on the Cisco VPN router and the AWS private virtual gateway are not likely to be the cause of the problem because the site-to-site VPN tunnel is already up and the site-to-site routing works correctly.

NEW QUESTION # 22
An engineer is implementing a highly securemultitierapplication in AWS that includes S3. RDS, and some additional private links. What is critical to keep the traffic safe?
- A. specific routing and bucket policies
- B. EC2 super policies and specific routing policies
- C. gateway load balancers and specific routing policies
- D. VPC peering and bucket policies
Answer: A
Explanation:
A highly secure multitier application in AWS that includes S3, RDS, and some additional private links requires specific routing and bucket policies to keep the traffic safe. The reasons are as follows:
Specific routing policies are needed to ensure that the traffic between the tiers is routed through the private links, which provide secure and low-latency connectivity between AWS services and on-premises resources12. The private links can also prevent the exposure of the data and the application logic to the public internet12.
Bucket policies are needed to control the access to the S3 buckets that store the application data34. Bucket policies can specify the conditions under which the requests are allowed or denied, such as the source IP address, the encryption status, the request time, etc.34. Bucket policies can also enforce encryption in transit and at rest for the data in S334.

NEW QUESTION # 24
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. star topology with internet-based VPN connections and BGP for routing
- C. fully meshed topology with SD-WAN technology using dynamic routing and prioritized traffic for QoS
- D. hub-and-spoke topology using MPLS with static routing and dedicated bandwidth for QoS
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:
