@Anonymous, thanks. i also studied the same questions but failed.
There are about 20 questions with wrong answers.
Pls advise if you have any idea of correct answers

@superman took it yesterday and got 9xx i choseC for BFD

An engineer is working on an OSPF network design and wants to minimize the failure detection time and the impact on the router CPU. Witch technology accomplishes this goal?

BFD can provide fast failure detection times for all media types, encapsulations, topologies, and routing protocols. In the best-case scenario, it can provide fast failure detection similar to that found in POS.

@No LTE

@superman

What should be implemented to prevent exceeding the 50MB allowable bandwidth of internet circuit?
A. CIR
B. police
C. shaping
D. ACL
E. rate-limit
Answer: C

There are two reasons why you might want to configure shaping:

Instead of waiting for the policer of the ISP to drop your traffic, you might want to shape your outgoing traffic towards the ISP so that they don’t drop it.
To prevent egress blocking. When you go from a high speed interface to a low speed interface you might get packet loss (tail drop) in your outgoing queue. We can use shaping to make sure everything will be sent (until its buffer is full).

@AST

which two characteristics of MSDP when designing an interdomain multicast network are true.

*MDSP is a mechanism that allows RPs to share information about active sources
*In the PIM-SM model Mutlicast sources and recievers must register with their local RP

hey all!

I’ll be sitting for the test tomorrow morning. I studied passleader709q – I’m very nervous with all the people stating the issues with that dump. any last minute advice will be great! I have about 15 hours before I take the exam.

I’ll check in after I fail or pass. Thanks to all those actually posting helpful advice!

New question, Diagram with four switches and same config but different bandwidth, question is to select the root switch (answer need to chose with the lowest mac address, believe switch S3).

@Ast if you list the questions from 410q dump that are wrong, lets review them together. I have few weeks before I take mine.

E. the 0x01004f MAC address prefix is used for mapping IP addresses to MAC addresses
F. the 0x01005e MAC address prefix is used for mapping IP addresses to MAC addresses

Answer: D and F
Ethernet & FDDI Multicast Addresses

– The low order bit (0x01) in the first octet indicates that this packet is a Layer 2 multicast packet. Furthermore,
the “0x01005e” prefix has been reserved for use in mapping L3 IP multicast addresses into L2 MAC addresses.
– When mapping L3 to L2 addresses, the low order 23 bits of the L3 IP multicast address are mapped into the
low order 23 bits of the IEEE MAC address. Notice that this results in 5 bits of information being lost.

Hi guys,

Planning to take the exam in feb 2020. Have read the book and watched nuggets, but want to pass the first or 100% the second time. Anyone suggestions for good dump? I heard SPOTOs dumps are reliable, but am not 100% sure. What do you guys think?

Which statement is correct regarding NBAR and NetFlow?
A. NetFlow uses five key fields for the flow.
B. NBAR examines data in Layers 3 and 4.
C. NetFlow examines data in Layers 3 and 4.
D. NBAR examines data in Layers 2 through 4.
E. NetFlow examines data in Layers 2 through 4.

Answer should be C. because NBAR work until layer 7.

Which configuration represents resiliency at the hardware and software layers?
A. multiple connections and FHRP
B. HSRP and GLBP
C. redundant supervisor and power supplies
D. dual uplinks and switches
should it be C instead A

A. routed mode
B. multicontext mode
C. transparent mode

What is an advantage of using the vPC feature in a data center environment?
A. VSS is a requirement.
B. Multiple instances of control plane are formed.
C. The control plane and management plane remain separate.
D. Cisco FabricPath technology does not have to be configured.
I believe Answer is B as some dump say Answer: C

“Each peer device in the vPC domain runs its own control plane, and both devices work independently. Any potential control plane issues stay local to the peer device and does not propagate or impact the other peer device.”

cisco.com/c/dam/en/us/td/docs/switches/datacenter /sw/design/vpc_design/vpc_best_practices_design_guide.pdf

Based on above statement I would also say B, Answer C is also correct but not because of the vPC feature.

******************************************************************

I believe answer is A
cisco.com/c/en/us/td/docs/security/nac/appliance/configuration_guide/48/cam/48cam-book/m_intro.html

NAC Appliance lets you block access or quarantine users who do not comply with your security requirements,
NAC Appliance enforces security policies by blocking, isolating, and repairing noncompliant machines in a quarantine area without needing administrator attention.
Quarantining allows remediation servers to provide operating system patches and updates, virus definition files, or endpoint security solutions to compromised or vulnerable devices.

Since there is no any word regarding quarantine in option B, denying access to clients would be the next action by NAC Appliance.

******************************************************************

Pls advise the answer, i found some say A and B, other dump say C and D.

Below descpritions from CCDP ARCH 300-320 fourth edition:

“EoR requires a smaller number of capable switches. EoR reduces the management overhead, simplifies STP topology, and requires fewer ports in the aggregation layer. However, in large-scale networks, EoR may require extensive copper cabling from hundreds of servers to the end of the row and more infrastructure for patching and cabling. This translates to more operational complexity.
In contrast, ToR contains the servers’ copper cabling in the rack, reducing the cable and patching infrastructure and using fiber connections with higher capacity. In addition, ToR physical topology is more modular because each rack presents a module that can be upgraded and changed with no effect on the other racks. ToR, however, requires a larger number of switches, thus increasing the management overhead. More ports are required in the aggregation layer, and the STP topology gains complexity.
”

Based on above I would say B and D

******************************************************************

Which statement is correct regarding NBAR and NetFlow?
A. NetFlow uses five key fields for the flow.
B. NBAR examines data in Layers 3 and 4.
C. NetFlow examines data in Layers 3 and 4.
D. NBAR examines data in Layers 2 through 4.
E. NetFlow examines data in Layers 2 through 4.

Cisco standard NetFlow version 5 defines a flow as a unidirectional sequence of packets that all share the following 7 values:[2]

Ingress interface (SNMP ifIndex)
Source IP address
Destination IP address
IP protocol
Source port for UDP or TCP, 0 for other protocols
Destination port for UDP or TCP, type and code for ICMP, or 0 for other protocols
IP Type of Service

So I would say the Answer is C also
******************************************************************

Which configuration represents resiliency at the hardware and software layers?
A. multiple connections and FHRP
B. HSRP and GLBP
C. redundant supervisor and power supplies
D. dual uplinks and switches
should it be C instead A

I would also agree C would meet this requirement

During an upgrade of an existing data center, a network team must design segmentation into existing networks. Due to legacy applications, the IP addresses cannot change. Which firewall deployment model meets these requirements?
A. routed mode
B. multicontext mode
C. transparent mode
D. cluster mode

Pls advise the answer, I think A: routed mode is correct.

Based on question and available answers I would answer A for this one.
