link is not working...can someone share the alternative link pls.... Thanks

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

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...

Another One CONNECTIVITY / CAPEX / OPEX / ANNUAL / INSTALLATION FEE / TERM DWDM over dark fiber / $250,000 / $100,000 / $30,000 / 60 months CWDM over dark fiber / $150,000 / $100,000 / $25,000 / 50 months MPLS wire only / $50,000 / $150,000 / $75,000 / 12 months Metro Ethernet / $45,000 / $120,000 / $5,000 / 36 months Refer to the table. A customer investigates connectivity options for a DCI between two production data centers. The solution must provide dual 10G connections between locations with no single points of failure for Day 1 operations it must also include an option to scale for up to 20 resilient connections in the second year to accommodate isolated SAN over IP and isolated, dedicated replication IP circuits, All connectivity methods are duplex 10 Gbps Which transport technology costs the least over two years, in this scenario? A. Metro Ethernet B. DWDM C. MPLS D. CWDM Simply go with B as only DWDM can scale up to the requirement.

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 - OSPF Design Guide - Cisco 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 OSPF Convergence and typologies (cisco.com) Looks like C Ring is right Ans.

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.

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 ?

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.

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.

Agree A and E. here is link for E - [Hidden Content]

Ans is A Very well explain on this link [Hidden Content] Refer Use case 2

Interesting...Large scale mean - high speed link which can exclude CDWM. because CDWM best option are 10 Gbps and 16 Gbps whereas DWDM can go up 400 Gbps... Here is another one with QoS trick CONNECTIVITY / CAPEX / OPEX / ANNUAL / INSTALLATION FEE / TERM DWDM over dark fiber / $200,000 / $100,000 / $30,000 / 12 months CWDM over dark fiber / $150,000 / $100,000 / $25,000 / 18 months MPLS wire only / $50,000 / $80,000 / $5,000 / 12 months Metro Ethernet / $45,000 / $100,000 / $5,000 / 36 months Refer to the table. A customer investigates connectivity options for a DCI between two production data centers to aid a large-scale migration project. The solution must provide a single 10G connection between locations and be able to run its own varying QoS profiles without service provider interaction based on the migration stages. All connectivity methods are at 10 Gbps. Which transport technology costs the least of the connectivity is required for just one year? A. Metro Ethernet B. MPLS C. DWDM over dark fiber D. CWDM over dark fiber In this i can safely say CWDM because of two reason...QOS and second 10Gb is perfect speed offered by CDWM with less cost. [Hidden Content]

Here is link for Cisco Zero Trust Architecture CZTA focus on workplace, workload and workforce. Thanks

CONNECTIVITY / CAPEX / OPEX / ANNUAL / INSTALLATION FEE / TERM DWDM over dark fiber / $200,000 / $100,000 / $30,000 / 12 months CWDM over dark fiber / $150,000 / $100,000 / $25,000 / 18 months MPLS wire only / $50,000 / $180,000 / $5,000 / 12 months Metro Ethernet / $65,000 / $100,000 / $5,000 / 36 months Refer to the table A customer investigates connectivity opt for a DCI between two production data centers to aid a large-scale migration project. The migration is estimated to take 20 months to complete but might extend an extern 10 months if issues arise. All connectivity options meet the requirements to migrate workloads. Which transport technology provides the best ROI based-on cost and flexibility? A. Metro Ethernet B. MPLS C. DWDM over dark fiber D. CWDM over dark fiber Lets discuss which one is best ans and why ? My vote is with Option A because its lest expensive in simple math. but i may b missing the trick as CCDE do not test our math skills.
