NEW QUESTION 4
Customer XYZ network consists of an MPLS core. IS-IS running as IGP a pair of BGP route reflectors for route propagation, and a few dozens of MPLS-TE tunnels for specific tactical traffic engineering requirements. The customer's engineering department has some questions about the use of the Overload Bit in the IS-IS networks and how it could be used to improve their current network design. Which two concepts about the Overload Bit are true? (Choose two.)
- A. It can be set on a router during the startup process for a fixed period of time
- B. Networks advertised within the LSPs of the respective node will become unreachable
- C. It forces the midpoint MPLS-TE node to reoptimize the primary tunnels going through the OL node.
- D. It can be set on a router until other interacting protocols have signaled convergence.
- E. It is not recommended on BGP Route Reflectors
Answer: AD
NEW QUESTION 5
Company ABC wants to minimize the risk of users plugging unauthorized switches and hubs into the network Which two features can be used on the LAN access ports to support this design requirement? (Choose two.)
- A. Loop Guard
- B. PortFast
- C. DTF
- D. Root Guard
- E. BPDU Guard
Answer: BE
NEW QUESTION 6
How many fully established neighbour relationships exist on an Ethernet with five routers running OSPF as network type broadcast?
- A. 5
- B. 6
- C. 7
- D. 10
- E. 20
Answer: C
Explanation:
Assuming routers R1-R5, R1 is elected DR, R2 BDR. Fully established neighborships only occur to DR and BDR, all other neighbors are in 2Way DR other state. DR|BDRFull relationships:
R2-R1 R3-R1 R3-R2 R4-R1 R4-R2 R5-R1 R5-R2
NEW QUESTION 7
If the desire is to connect virtual network functions together to accommodate different types of network service connectivity what must be deployed?
- A. bridging
- B. service chaining
- C. linking
- D. daisy chaining
- E. switching
Answer: B
Explanation:
Service chaining is the technique of connecting virtual network functions together to provide different types of network service connectivity. Service chaining uses software-defined networking (SDN) programmability to create a chain of connected network services, such as firewalls, load balancers, NAT, and intrusion protection. Service chaining can automate the provisioning of network applications that have different characteristics and requirements, such as security, latency, or quality of service (QoS). Service chaining can also optimize the use of network resources and improve application performance by using SDN analytics and performance tools to select the best available network paths and avoid network congestion. Service chaining is being used in many SDN and network functions virtualization (NFV) use cases and deployments, such as data centers, carrier networks, and virtual customer edge123. References:

- A. Sensors
- B. Security
- C. Applications
- D. Wi-Fi Infrastructure
- E. Ethernet Switches
Answer: A
NEW QUESTION 9
Company XYZ wants to use the FCAPS ISO standard for network management design. The focus of the design should be to monitor and keep track of any performance issues by continuously collecting and analyzing statistical information to monitor, correct, and optimize any reduced responsiveness across the network. Which layer accomplishes this design requirement?
- A. fault management
- B. accounting management
- C. performance management
- D. security management
Answer: C
NEW QUESTION 10
What is a description of a control plane action?
- A. de-encapsulating and re-encapsulating a packet in a data-link frame
- B. matching the destination MAC address of an Ethernet frame to the MAC address table
- C. matching the destination IP address of an IP packet to the IP routing table
- D. hosts locating routers that reside on attached links using the IPv6 Neighbor Discover Protocol
Answer: D
NEW QUESTION 11
Two routers R1 and R2 are directly connected through an Ethernet link. Both routers are running OSPF over the Ethernet link and OSPF has been registered with BFD. R1 has been set up to transmit BFD at a 50 ms interval, but R2 can receive only at a 100 ms rate due to platform limitations. What does this mean?
- A. After the initial timer exchang
- B. R2 sets its transmission rate to the R1 Desired Min TX interval
- C. After the initial timer exchang
- D. R1 sets its transmission rate to the R2 Required Min RX interval
- E. Timers renegotiate indefinitely, so the timer exchange phase never converges
- F. R2 sets the P-bit on all BFD control packets until R2 sends a packet with the F-bit set
Answer: B
NEW QUESTION 12
Which two data plane hardening techniques are true? (Choose two)
- A. warning banners
- B. redundant AAA servers
- C. Control Plane Policing
- D. SNMPv3
- E. infrastructure ACLs
- F. disable unused services
- G. routing protocol authentication
Answer: EF
NEW QUESTION 13
