Which reason prevents a designer from using a GDOI-based VPN to secure traffic that traverses the Internet?

A. Enterprise host IP addresses are typically not routable.

B. GDOI is less secure than traditional IPsec.

C. Network address translation functions interfere with tunnel header preservation.

Which major block is not included in the ETSI network Function Virtualization reference framework?

A. Network Function Virtualization Infrastructure

B. Network Function Virtualization Management and Orchestration

Which option is a design consideration when using routers in a distributed hardware architecture?

A. Routing information is stored in the RIB and the FIB makes forwarding decisions as programmed on the line card hardware

B. After a link failure occurs in the core, the RIB continues to forward the traffic while FIB convergence is in progress

C. BGP routes are stored in the RIB and IGP routes are stored in the FIB

D. IP routes are stored in the RIB and MPLS labels are stored in the FIB

Refer to the exhibit.

A customer currently has a large EIGRP-based network with several remote sites attached. All remote sites connect to the two corporate data centers, depicted as 10.1.1.0 and 10.1.2.0. The customer has experienced several network-wide failures where neighbors were stuck-in-active and had other network stability issues due to some links flapping. Which two redesign options increase stability and reduce the load on the remote site routers, still maintaining optimal routing between remote sites and the two data centers? (Choose two)

A. Set the data center routers as stub-routers

B. Perform summarization at the data centers, selectively leaking routes sent to the remote sites

C. Perform summarization at the remote sites, selectively leaking routes sent to the data centers

D. Set the hello interval timer to be larger than the hold interval

E. Increase the hold interval to accommodate lost hello packets on error-prone links

Which two items are required for data plane hardening of an infrastructure device? (Choose two)

A. Disable unused services

B. Routing protocol authentication

C. SNMPv3

D. Redundant AAA servers

E. Infrastructure ACLs

F. Warning banners

G. Control Plane Policing

Which IEEE standard is commonly used at the data link layer for an access network, in an IoT environment?

A. Wireless Regional Area Network

B. Low-Rate Wireless Network

C. Wireless Local Area Network

D. Broadband wireless metropolitan Network

You have been asked to design a wireless network solution that will implement context- aware services on an existing network that was initially deployed for data traffic only. Which two design principles would you follow to increase the location accuracy with the least possible impact on the current setup? (Choose two.)

A. Use directional antennas to provide better cell separation.

B. Add access points along the perimeter of the coverage area.

C. Install additional APs in monitor mode where the co-channel interference would otherwise be affected.

D. Increase the AP density to create an average inter-access point distance of less than 40 ft.| 12.2meters

E. Fine tune the access point's radio configuration to have a higher average transmission power to achieve better coverage.

Refer to the exhibit.

A. Multipoint-to-point LDP

B. MSDP

C. MLDP VPN

D. Rosen Draft using LDP
