Which Microsoft Azure service enables a dedicated and secure connection between an on-premises infrastructure and Azure data centers through a colocation provider?
Azure Private Link
Azure ExpressRoute
Azure Virtual Network
Azure Site-to-Site VPN
Azure ExpressRoute is a service that enables a dedicated and secure connection between an on-premises infrastructure and Azure data centers through a colocation provider. A colocation provider is a third-party data center that offers network connectivity services to multiple customers. Azure ExpressRoute allows customers to bypass the public internet and connect directly to Azure services, such as virtual machines, storage, databases, and more. This provides benefits such as lower latency, higher bandwidth, more reliability, and enhanced security. Azure ExpressRoute also supports hybrid scenarios, such as connecting to Office 365, Dynamics 365, and other SaaS applications hosted on Azure. Azure ExpressRoute requires a physical connection between the customer's network and the colocation provider's network, as well as a logical connection between the customer's network and the Azure virtual network. The logical connection is established using a Border Gateway Protocol (BGP) session, which exchanges routing information between the two networks. Azure ExpressRoute supports two models: standard and premium. The standard model offers connectivity to all Azure regions within the same geopolitical region, while the premium model offers connectivity to all Azure regions globally, as well as additional features such as increased route limits, global reach, and Microsoft peering.Reference:Designing and Implementing Cloud Connectivity (ENCC) v1.0,Learning Plan: Designing and Implementing Cloud Connectivity v1.0 (ENCC 300-440) Exam Prep,ENCC | Designing and Implementing Cloud Connectivity | Netec

An engineer is implementing a highly secure multitier application in AWS that includes S3. RDS, and some additional private links. What is critical to keep the traffic safe?
VPC peering and bucket policies
specific routing and bucket policies
EC2 super policies and specific routing policies
gateway load balancers and specific routing policies
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.

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?
wrong ISAKMP policy
identity mismatch
wrong encryption
IKE version mismatch
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.Reference:=

Which command is missing on router R2?
A company with multiple branch offices wants a connectivity model to meet its network architecture requirements. The company focuses on ensuring low latency and efficient routing for its critical business applications. Which connectivity model meets these requirements?
hub-and-spoke topology with SD-WAN technology, using dynamic routing and OSPF as the routing protocol
fully meshed topology with SD-WAN technology, using dynamic routing and BGP as the routing protocol
point-to-point topology using dedicated leased lines and static routing
star topology with internet-based VPN connections and static routing
A fully meshed topology with SD-WAN technology, using dynamic routing and BGP as the routing protocol, meets the requirements of the company because it provides the following benefits:
It allows direct and secure connectivity between any two branch offices, without the need for a central hub or intermediary devices12. This reduces the latency and improves the performance of the critical business applications.
It leverages SD-WAN technology to optimize the traffic flow and application quality of service (QoS) across the WAN13.SD-WAN can dynamically select the best path for each application based on the network conditions and policies13.SD-WAN can also provide redundancy, security, and visibility for the WAN13.
It uses dynamic routing and BGP as the routing protocol to exchange routing information and establish connectivity between the branch offices14.BGP is a scalable and flexible protocol that can support multiple address families, such as IPv4 and IPv6, and multiple routing policies, such as local preference and route filtering14.BGP can also enable seamless integration with the cloud service providers (CSPs) and internet service providers (ISPs)14.
