NEW QUESTION 1
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?
A. VPC peering and bucket policies
B. specific routing and bucket policies
C. EC2 super policies and specific routing policies
D. gateway load balancers and specific routing policies
Answer: B
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 resources. The private links can also prevent the exposure of the data and the application logic to the public internet.
– Bucket policies are needed to control the access to the S3 buckets that store the application data. 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. Bucket policies can also enforce encryption in transit and at rest for the data in S3.
NEW QUESTION 2
What is the role of service providers to establish private connectivity between on-premises networks and Google Cloud resources?
A. Facilitate direct, dedicated network connections through Google Cloud Interconnect.
B. Enable intelligent routing and dynamic path selection using software-defined networking.
C. Provide end-to-end encryption for data transmission using native IPsec.
D. Accelerate content delivery through integration with Google Cloud CDN.
Answer: A
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.
NEW QUESTION 3
An engineer must configure an IPsec tunnel to the cloud VPN gateway. Which Two actions send traffic into the tunnel? (Choose two.)
A. Configure access lists that match the interesting user traffic.
B. Configure a static route.
C. Configure a local policy in Cisco vManage.
D. Configure an IPsec profile and match the remote peer IP address.
E. Configure policy-based routing.
Answer: AE
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.
NEW QUESTION 4
Which architecture model establishes internet-based connectivity between on-premises networks and AWS cloud resources?
A. That establishes an iPsec VPN tunnel with Internet Key Exchange (IKE) for secure key negotiation and encrypted data transmission.
B. That relies on AWS Elastic Load Balancing (ELB) for traffic distribution and uses SSL/TLS encryption for secure data transmission.
C. That employs AWS Direct Connect for a dedicated network connection and uses private IP addresses tor secure communication.
D. That uses Amazon CloudFront for caching and distributing content globally and uses HTTPS for secure data transfer.
Answer: A
Explanation:
The architecture model that establishes internet-based connectivity between on-premises networks and AWS cloud resources is the one that establishes an iPsec VPN tunnel with Internet Key Exchange (IKE) for secure key negotiation and encrypted data transmission. This model is also known as the VPN CloudHub model. It allows multiple remote sites to connect to the same virtual private gateway in AWS, creating a hub-and-spoke topology. The VPN CloudHub model provides the following benefits:
– It enables secure communication between remote sites and AWS over the public internet, using encryption and authentication protocols such as IPsec and IKE. It supports dynamic routing protocols such as BGP, which can automatically adjust the routing tables based on the availability and performance of the VPN tunnels.
– It allows for redundancy and load balancing across multiple VPN tunnels, increasing the reliability and throughput of the connectivity.
– It simplifies the management and configuration of the VPN connections, as each remote site only needs to establish one VPN tunnel to the virtual private gateway in AWS, rather than multiple tunnels to different VPCs or regions.
NEW QUESTION 5
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. EC2 Trust Lock
B. security groups
C. tagging
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.
NEW QUESTION 6
Which feature is unique to Cisco SD-WAN IPsec tunnels compared to native IPsec VPN tunnels?
A. real-time dynamic path selection
B. tunneling protocols
C. end-to-end encryption
D. authentication mechanisms
Answer: A
Explanation:
Cisco SD-WAN IPsec tunnels are different from native IPsec VPN tunnels in several ways. One of the unique features of Cisco SD-WAN IPsec tunnels is that they support real-time dynamic path selection, which means that they can automatically choose the best path for each application based on the network conditions and policies. This feature improves the performance, reliability, and efficiency of the network traffic. Native IPsec VPN tunnels, on the other hand, do not have this capability and rely on static routing or manual configuration to select the path for each tunnel. This can result in suboptimal performance, increased latency, and higher costs.
NEW QUESTION 7
Which approach does a centralized internet gateway use to provide connectivity to SaaS applications?
A. A cloud-based proxy server routes traffic from the on-premises infrastructure to the SaaS provider data center.
B. Internet traffic from the on-premises infrastructure is routed through a centralized gateway that provides access controls for SaaS applications.
C. VPN connections are used to provide secure access to SaaS applications from the on-premises infrastructure.
D. A dedicated, private connection is established between the on-premises infrastructure and the SaaS provider data center using colocation services.
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 hub. 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 links. A centralized internet gateway can use various technologies to provide connectivity to SaaS applications, such as proxy servers, firewalls, web filters, and WAN optimizers. 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 center. 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 infrastructure. Therefore, the correct answer is option B, which describes the basic function of a centralized internet gateway.

ExpressRoute is a service that provides a dedicated, private, and high-bandwidth connection between the customer’s on-premises network and Microsoft Azure cloud network. 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 databases. 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-WAN. 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 balancing. SDCI also provides high availability by using dynamic routing protocols and encryption mechanisms to ensure optimal and secure path selection.
– Redundancy: ExpressRoute circuits can be paired together to form a redundant connection between the customer’s network and Azure. SDCI also supports redundancy by allowing multiple connections between data centers and cloud providers, using different transport technologies and service levels.
– Low latency: ExpressRoute circuits offer lower latency than public internet connections, as they bypass the congestion and variability of the internet. 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 providers.
NEW QUESTION 10
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 or internal 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 customer. 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 11
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?
A. hub-and-spoke topology with SD-WAN technology, using dynamic routing and OSPF as the routing protocol
B. fully meshed topology with SD-WAN technology, using dynamic routing and BGP as the routing protocol
C. point-to-point topology using dedicated leased lines and static routing
D. star topology with internet-based VPN connections and static routing
Answer: B
Explanation:
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 devices. 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 WAN. SD-WAN can dynamically select the best path for each application based on the network conditions and policies. SD-WAN can also provide redundancy, security, and visibility for the WAN.
– It uses dynamic routing and BGP as the routing protocol to exchange routing information and establish connectivity between the branch offices. 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 filtering. BGP can also enable seamless integration with the cloud service providers (CSPs) and internet service providers (ISPs).
NEW QUESTION 12
Which Microsoft Azure service enables a dedicated and secure connection between an on-premises infrastructure and Azure data centers through a colocation provider?
A. Azure Private Link
B. Azure ExpressRoute
C. Azure Virtual Network
D. Azure Site-to-Site VPN
Answer: B
Explanation:
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.
