NEW QUESTION # 26
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. site-to-site VPN with Azure VPN gateway
- B. hybrid connectivity with SD-WAN
- C. ExpressRoute with private peering using SDCI
- D. AWS Direct Connect with dedicated connections
Answer: C
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.

Which method is used to create authorization boundary diagrams (ABDs)?
- A. identify only interconnected systems that are FedRAMP-authorized
- B. identify all tools as either external or internal to the boundary
- C. show all networks in CIDR notation only
- D. show only minor or small upgrade level software components
Answer: B
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 # 31
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. gateway load balancers and specific routing policies
- B. specific routing and bucket policies
- C. EC2 super policies and specific routing policies
- D. VPC peering and bucket 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 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 # 32
Which architecture model establishes internet-based connectivity between on-premises networks and AWS cloud resources?
- A. That relies on AWS Elastic Load Balancing (ELB) for traffic distribution and uses SSL/TLS encryption for secure data transmission.
- B. That uses Amazon CloudFrontfor caching and distributing content globally and uses HTTPS for secure data transfer.
- C. That establishes an iPsec VPN tunnel with Internet Key Exchange (IKE) for secure key negotiation and encrypted data transmission
- D. That employs AWS Direct Connect for a dedicated network connection and uses private IP addresses tor secure communication.
Answer: C
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 model12. It allows multiple remote sites to connect to the same virtual private gateway in AWS, creating a hub-and-spoke topology1. The VPN CloudHub model provides the following benefits12:
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.
The other options are not correct because they do not establish internet-based connectivity between on-premises networks and AWS cloud resources. Option B relies on AWS Elastic Load Balancing (ELB) for traffic distribution and uses SSL/TLS encryption for secure data transmission. However, ELB is a service that distributes incoming traffic across multiple targets within a VPC, not across different networks3. Option C employs AWS Direct Connect for a dedicated network connection and uses private IP addresses for secure communication. However, AWS Direct Connect is a service that establishes a private connection between on-premises networks and AWS, bypassing the public internet4. Option D uses Amazon CloudFront for caching and distributing content globally and uses HTTPS for secure data transfer. However, Amazon CloudFront is a service that delivers static and dynamic web content to end users, not to on-premises networks5.

NEW QUESTION # 34
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. star topology with internet-based VPN connections and static routing
- C. fully meshed topology with SD-WAN technology, using dynamic routing and BGP as the routing protocol
- D. point-to-point topology using dedicated leased lines and static routing
Answer: C
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 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.
