New Question 1:
What advantage of placing the IS-IS layer 2 flooding domain boundary at the core Layer in a three-layer hierarchical network is true?
A. The Layer 1 and Layer 2 domains can easily overlap
B. It reduces the complexity of the Layer 1 domains
C. It can be applied to any kind of topology
D. The Layer 2 domain is contained and more stable
Correct Answer: D
New Question 2:
What is a characteristic of a secure cloud architecture model?
A. limited access to job function
B. dedicated and restricted workstations
C. multi-factor authentication
D. software-defined network segmentation
Correct Answer: D
New Question 3:
When designing a WAN that will be carrying real-time traffic, what are two important reasons to consider serialization delay? (Choose two )
A. Serialization delays are invariable because they depend only on the line rate of the interface
B. Serialization delays are variable because they depend on the line rate of the interface and on the type of the packet being serialized.
C. Serialization delay is the time required to transmit the packet on the physical media.
D. Serialization delays are variable because they depend only on the size of the packet being serialized
E. Serialization delay depends not only on the line rate of the interface but also on the size of the packet
Correct Answer: BD
New Question 4:
Which two features describe controller-based networking solutions compared to traditional networking solutions? (Choose two.)
A. inflate licensing costs
B. reduce network configuration complexity
C. provide centralization of primary IT functions

A. software plane
B. control plane
C. application plane
D. management plane

New Question 6:
The Company XYZ network is experiencing attacks against their router. Which type of Control Plane Protection must be used on the router to protect all control plane IP traffic that is destined directly for one of the router interfaces?
A. Control Plane Protection host subinterface
B. Control Plane Protection main interface
C. Control Plane Protection transit subinterface
D. Control Plane Protection CEF-exception subinterface
Correct Answer: A
New Question 7:
Which architecture does not require an explicit multicast signaling protocol, such as PIM or P2MP, to signal the multicast state hop-by-hop, but instead uses a link state protocol to advertise the multicast forwarding state?
A. Binary indexed explicit routing
B. Binary intermediate enhanced routing
C. Bit indexed explicit replication
D. Bi-directional implicit replication
Correct Answer: C
New Question 8:
A network engineering team is in the process of designing a lab network for a customer demonstration. The design engineer wants to show that the resiliency of the MPLS traffic Engineering Fast Reroute solution has the same failover/ failback times as a traditional SONET/SDH network (around 50MSEC). In order to address both link failure and node failure within the lab typology network, which type of the MPLS TE tunnels must be considered for this demonstration?
A. TE backup tunnel
B. Next-hop (NHop) tunnel
C. FRR Backup tunnel
D. next-next-hop (NNHop) tunnel
Correct Answer: D
New Question 9:
A company plans to use BFD between its routers to detect a connectivity problem inside the switched network. An IPS is transparently installed between the switches. Which packets shold the IPS forward for BFD to work under all circumstances?
A. Fragmented packet with the do-not-fragment bit set
B. IP packets with broadcast IP source addresses
C. IP packets with the multicast IP source address
D. IP packet with the multicast IP destination address
E. IP packets with identical source and destination IP addresses
F. IP packets with the destination IP address 0.0.0.0.
Correct Answer: E
New Question 10:
Retef to the exhibit.
An engineer is designing a multiarea OSPF network for a client who also has a large EIGRP domain EIGRP routes are getting redistributed into OSPF ,OSPF area 20 has routers with limited memory and CPU resources The engineer wants to block routes from EIGRP 111 from propagating into area 20 and allow EIGRP 222 routes to how in.
