Correct Ans is A and E.. Refer below bold remarks meet both the condition mention in question...and definition is from above cisco link

IPv6 Prefix Guard Overview
The IPv6 Prefix Guard feature works within the IPv6 Source Guard feature, enabling the device to deny traffic originated from nontopologically correct addresses. IPv6 prefix guard is often used when IPv6 prefixes are delegated to devices (for example, home gateways) using DHCP prefix delegation. The feature discovers ranges of addresses assigned to the link and blocks any traffic sourced with an address outside this range.

IPv6 Destination Guard Overview
The IPv6 Destination Guard feature works with IPv6 neighbor discovery to ensure that the device performs address resolution only for those addresses that are known to be active on the link. It relies on the address glean functionality to populate all destinations active on the link into the binding table and then blocks resolutions before they happen when the destination is not found in the binding table.

Company XYZ, a global content provider, owns data centers on different continents. Their data center design involves a standard three-layer design with a Layer 3-only core. HSRP is used as the FHRP. They require VLAN extension across access switches in all data centers, and they plan to purchase a Layer 2 interconnection between two of their data centers in Europe. In the absence of other business or technical constraints, which termination point is optimal for the layer 2 interconnection?
A. at the access layer because the STP root bridge does not need to align with the HSRP active node
B. at the core layer, to offer the possibility to isolate STP domains
C. at the core layer because all external connections must terminate there for security reasons
D. at the aggregation layer because it is the Layer 2 to Layer 3 demarcation point

 

Please comment on this one..

I will go with B because Core is only Layer 3 device which host the SVI for all the vlans, it means connecting the L2 link on Core switches will ensure gateway reachability from other DC.

Which purpose of a dynamically created tunnel interface on the design of IPv6 multicast services is true?
A. first-hop router registration to the RP
B. multicast client registration to the RP
C. multicast source registration to the RP
D. Transport of all IPv6 multicast traffic.

 

Any suggestion on this one ?

Which two application requirements are mandatory for traffic to receive proper treatment when placed in the priority queue? (Choose two.)
A. intolerance to jitter
B. TCP-based application
C. FC WRED drop treatment
D. small transactions (HTTP-like behavior)
E. tolerance to packet loss

 

Agree with A...but couldn't find second option. 

E could be second option because LLQ also allows queue depths to be specified to determine when the router should drop packets if too many packets are waiting in any particular class queue.

In an OSPF network with routers connected together with Ethernet cabling, which topology typically takes the longest to converge?
A. partial mesh
B. triangulated
C. ring
D. squared
E. full mesh

A will win from E because OSPF design guide -

B and D can be easily ruled out because we cannot triangulated or squared 20 router with ethernet cable...

Now we need to delibrate between C and E . Discussed on Cisco learning site

Looks like C Ring is right Ans.

As part of workspace digitization, a large enterprise has migrated all their users to Desktop as a Service (DaaS) by hosting the backend system in their on-premises data center. Some of the branches have started to experience disconnections to the DaaS at periodic intervals, however, local users in the data center and head office do not experience this behavior. Which technology can be used to mitigate this issue?
A. WRED
B. tall drop
C. traffic policing
D. Traffic shaping

Any suggestion...

Thanks for the update changed answer in vce, as we work through them all i will share the final version again, go team!

7 is correct Ans because  In broadcast network...Router can either be DR or BDR or NON-DR/NON-BDR, NON-DR/NON-BDR router can become neighbor with another NON-DR/NON-BDR router but their state stop at 2-way not full.
All NON-DR/NON-BDR router will have full neighborship with DR/BDR. So we have 3 NON-DR/NON-BDR Router in question which will have full neighborship with DR and BDR so 6 Full Neighborship and one more full neighborship between DR and BDR so total is 7

B is correct, this would be similar to a DCI link which terminates on the core and not on access or aggregation switches

My second thought was shaping outbound to keep the traffic smooth and consistent from the remote side but that does nothing if not applied to the DC side as well

Document suggests A. That is incorrect. Correct answer should be C.

In a PIM-SM network, sources must send their traffic to the RP. In sparse mode, a router assumes that other routers do not want to forward multicast packets for a group, unless there is an explicit request for the traffic. When hosts join a multicast group, the directly connected routers send PIM Join messages toward the RP. The RP keeps track of multicast groups. Hosts that send multicast packets are registered with the RP by the first hop router of that host. The RP then sends Join messages toward the source. At this point, packets are forwarded on a shared distribution tree. If the multicast traffic from a specific source is sufficient, the first hop router of the host may send Join messages toward the source to build a source-based distribution tree.

Automatic Multicast Tunneling (AMT) provides a method to tunnel multicast data over a unicast network. The tunneling is performed between AMT relays and AMT gateways, using User Datagram Protocol (UDP) encapsulation. AMT enables service providers and their customers to participate in delivering multicast traffic even in the absence of end-to-end multicast connectivity.
