Latest and Most Accurate Amazon AWS-Certified-Advanced-Networking-Specialty Dumps Exam Questions and Answers:

Question: 6

You are the AWS cloud architect and have been tasked with designing an appropriate subnetting design for your production VPC. Your production VPC requires secure communications back to the corporate private network. Quality of Service (QoS) is very important 24×7 for this particular connection, as real-time data is passed continually backwards and forwards between your on-prem bioinformatics enterprise application, and the number crunching servers deployed in the cloud. Any potential latency incurred on this connection will have a direct impact on the company’s ability to attract investors and expansion into new markets. Select the correct network configuration that best facilitates your company’s continued growth plans.

A. Provision a Direct Connect connection – between your service provider’s data center and the AWS region that your cloud compute resources exist in . Configure just a Private Virtual
Interface. As this is a Direct Connection, a Virtual Private Gateway is not required
B. Configure a site-to-site layer 2 software router using OpenVPN within your VPC and ensure that QoS enabled – this is a secure and cheap option
C. Configure a site-to-site layer 3 software router using OpenVPN within your VPC and ensure that QoS enabled – this is a secure and cheap option
D. Provision a Direct Connect connection – between your existing service provider’s data center and the AWS region that your cloud compute resources exist in. Configure a Virtual Private Gateway and Private Virtual Interface

Answer: D

Explanation:
Answers A, B, and C all rely on an Internet connection. An Internet connection cannot guarantee QoS and will be subject to performance fluctuations – therefore they are all incorrect options. The only difference between these options is whether a Virtual Private Gateway is required – the answer is yes and therefore the correct answer is D.

Question: 7

You are your company’s AWS cloud architect. You have created a VPC topology that consists of 3 VPCs. You have a centralised VPC (VPC-Shared) that provides shared services to the remaining 2 departmental dedicated VPCs (VPC-Dept1 and VPC-Dept2). The centralised VPC is VPC peered to both of the departmental VPCs, that is a VPC peering connection exists between VPC-Shared and VPC-Dept1, and a VPC peering connection exists between VPC-Shared and VPC-Dept2. Select the correct option from the list below.

A. Network traffic is possible between VPC-Shared instances and VPC-Dept1 and VPC-Dept2 instances as long as the appropriate routes and security groups are in place, but only for communication that is initiated from VPC1-Shared instances as the default peering bi-directional communication flag has been disabled.
B. Instances within VPC-Dept1 can communicate directly with instances in VPC-Shared, as long as the appropriate routes and security groups are in place, and vice versa regardless of who initiates communication
C. All network communication remains blocked between all VPCs until the respective peering bi-directional communication flags are set to the appropriate setting that allows traffic to flow.
D. Network traffic is possible between VPC-Shared instances and VPC-Dept1 and VPC-Dept2 instances as long as the appropriate routes and security groups are in place, but only for
communication that is initiated from VPC1-Shared instances as the default peering bi-directional communication flag has been enabled.

Answer: B

Explanation:
Answers A, C and D are incorrect answers as they reference a non-existing setting – there is no such thing as a “default peering bi-directional communication flag”.

Question: 8

In your current role as the corporate network architect – you have decided to replace your existing hardware firewall appliances with a pair of Juniper SRX-Series Services Gateways. You have chosen these as AWS lists these as supportable devices for establishing IPsec connections. With this in mind, select the minimum set of options to ensure that you can establish IPsec connectivity between your on premise private corporate network and your AWS hosted VPC. Select which option is NOT required

A. Initiate network connections from somewhere within your corporate network, this is required to bring the tunnels UP
B. Deploy a Customer Gateway within your corporate network
C. Deploy a Customer Gateway within your VPC
D. Deploy a Virtual Private Gateway within your VPC

Answer: B

Explanation:
A customer gateway within the corporate network is NOT required.
The Customer Gateway (CGW) is a component that you deploy within your VPC that logically represents you VPN physical hardware’s perimeter public IP – therefore Answer C is required.
A Virtual Private Gateway (VPG) is the AWS VPN Concentrator end point – and is always a requirement that needs to be deployed in your VPC – therefore it must always be deployed – therefore Answer D is required
AWS only supports IPsec in Tunnel mode – therefore Answer A is required.

Question: 9

The IPsec protocol suite is made up of various components covering aspects such as confidentiality, encryption, and integrity. Select the correct statement below regarding the correct configuration options for ensure IPsec confidentiality:

A. The following protocols may be used to configure IPsec confidentiality, DES, 3DES, MD5
B. The following protocols may be used to configure IPsec confidentiality, DES, 3DES, AES
C. The following protocols may be used to configure IPsec confidentiality, PSK, RSA
D. The following protocols may be used to configure IPsec confidentiality, PSK, MD5
E. The following protocols may be used to configure IPsec confidentiality, PSK, RSA

Answer: B

Explanation:
Answer A is incorrect – as MD5 is a hashing protocol (data integrity)
Answer C is incorrect – as PSK is short for Pre-Shared Keys (key exchange) – and again MD5 is a hashing protocol (data integrity)
Answer D is incorrect – as both MD5 and SHA are hashing protocols (data integrity)
Answer E is incorrect – as both PSK and RSA are used for key exchanges
This leaves Answer B is the only correct IPsec configuration covering confidentiality. DES, 3DES, and AES are all encryption protocols.

Question: 10

Which of the following statements does not describe Jumbo Frames in an AWS VPC environment?

A. For instances that are collocated inside a placement group, jumbo frames help to achieve the maximum network throughput possible
B. Jumbo Frames are not supported for traffic that exits the Virtual Private Gateway
C. Jumbo Frames are not supported for traffic that exits the Internet Gateway
D. T2.micro instances do not support Jumbo Frames
