by the key server over an existing IKE SA. Rekeying can use multicast or unicast messages. ReferencE. -3s/sec-get-vpn-xe-3s-book/sec-get-vpn.html QUESTION NO: 362 Which three statements about GET VPN are true? (Choose three.)A. It encrypts WAN traffic to increase data security and provide transport authentication. B. It provides direct communication between sites, which reduces latency and jitter. C. It can secure IP multicast, unicast, and broadcast group traffic. D. It uses a centralized key server for membership control. E. It enables the router to configure tunnels. F. It maintains full-mesh connectivity for IP networks. Answer: A,B,DExplanation: Cisco GET VPN Features and Benefits Feature Description and Benefit Key Services Key Servers are responsible for ensuring that keys are granted to authenticated and authorizeddevices only. They maintain the freshness of the key material, pushing re-key messages as wellas security policies on a regular basis. The chief characteristics include: • Key Servers can be located centrally, granting easy control over membership. • Key Servers are not in the "line of fire" - encrypted application traffic flows directly between VPNend points without a bottleneck or an additional point of failure. • Supports both local and global policies, applicable to all members in a group - such as "Permitany any", a policy to encrypt all traffic. Supports IP Multicast to distribute and manage keys, for improved efficiency; Unicast isalso supported where IP Multicast is not possible. Scalability and Throughput • The full mesh nature of the solution allows devices to communicate directly with eachother, without requiring transport through a central hub; this minimizes extra encrypts anddecrypts at the hub router; it also helps minimize latency and jitter. • Efficient handling of IP Multicast traffic by using the core network for replication canboost effective throughput further Cisco 400-101 Exam "Pass Any Exam.

Security Provides data security and transport authentication, helping to meet security complianceand internal regulation by encrypting all WAN traffic ReferencE. -vpn/product_data_sheet0900aecd80582067.html QUESTION NO: 363 Refer to the exhibit.If the traffic flowing from network 192.168.254.0 to 172.16.250.0 is unencrypted, which two actionsmust you take to enable encryption? (Choose two).A. Configure the transform-set on R2 to match the configuration on R1. B. Configure the crypto map on R2 to include the correct subnet. C. Configure the ISAKMP policy names to match on R1 and R2. D. Configure the crypto map names to match on R1 and R2. E. Configure the Diffie-Hellman keys used in the ISAKMP policies to be different on R1 and R2. Answer: A,BExplanation: A transform set combines an encryption method and an authentication method.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
