You are designing a network running both IPv4 and IPv6 to deploy QoS Which consideration is correct about the QoS for IPv4 and IPv6?
IPv4 and IPv6 traffic types can use use queuing mechanisms such as LLQ, PQ and CQ.
IPv6 packet classification is only available with process switching, whereas IPv4 packet classification is available with both process switching and CEF.
IPv6 and IB/4 traffic types can use a single QoS policy to match both protocols
Different congestion management mechanisms need to be used for IPv4 and IPv6 traffic types
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?
Fragmented packet with the do-not-fragment bit set
IP packets with broadcast IP source addresses
IP packets with the multicast IP source address
IP packet with the multicast IP destination address
IP packets with identical source and destination IP addresses
IP packets with the destination IP address 0.0.0.0.
A Tier-3 Service Provider is evolving into a Tier-2 Service Provider due to the amount of Enterprise business it is receiving The network engineers are re-evaluating their IP/MPLS design considerations in order to support duplicate/overlapping IP addressing from their Enterprise customers within each Layer3 VPN. Which concept would need to be reviewed to ensure stability in their network?
Assigning unique Route Distinguishers
Assigning unique Route Target ID'S
Assigning unique IP address space for the Enterprise NAT/Firewalls
Assigning unique VRF ID's to each L3VPN
Which three Cisco products are used in conjunction with Red Hat to provide an NFVi solution?
(Choose three.)
Cisco Prime Service Catalog
Cisco Open Virtual Switch
Cisco Nexus switches
Cisco UCS
Cisco Open Container Platform
Cisco Virtual Network Function
What are two key design principles when using a hierarchical core-distribution-access network model? (Choose two )
A hierarchical network design model aids fault isolation
The core layer is designed first, followed by the distribution layer and then the access layer
The core layer provides server access in a small campus.
A hierarchical network design facilitates changes
The core layer controls access to resources for security
A Service Provider is designing a solution for a managed CE service to a number of local customers using a single CE platform and wants to have logical separation on the CE platform using Virtual Routing and Forwarding (VRF) based on IP address ranges or packet length. Which is the most scalable solution to provide this type of VRF Selection process on the CE edge device?
Static Routes for Route Leaking
Policy Based Routing
OSPF per VRF Instance
Multi-Protocol BGP
An MPLS service provider is offering a standard EoMPLS-based VPLS service to Customer A. providing Layer 2 connectivity between a central site and approximately 100 remote sites.
Customer A wants to use the VPLS network to carry its internal multicast video feeds which are sourced at the central site and consist of 20 groups at Mbps each. Which service provider recommendation offers the most scalability?
EoMPLS-based VPLS can carry multicast traffic in a scalable manner
Use a mesh of GRE tunnels to carry the streams between sites
Enable snooping mechanisms on the provider PE routers.
Replace VPLS with a Layer 3 MVPN solution to carry the streams between sites
What best describes the difference between Automation and Orchestration?
Automation refers to an automatic process for completing a single task and Orchestration refers to assembling and coordinating a set of tasks and conditions.
Automation describes a hands-off configuration process while Orchestration refers to sets of automation tasks that require the network administrator to coordinate
Automation refers to an automatic process for completing multiple tasks with conditions and Orchestration refers to executing tasks in parallel.
Automation refers to scripting languages (Python. Ansible etc.) and Orchestration refers to commercial products that control configuration deployment
A customer asks you to perform a high level review of their upcoming WAN refresh for remote sites The review is specially focused on their retail store operations consisting of 500+ locations connected via mutlipoint IPsec VPN solution.
Which routing protocol would be valid but would also be the most restrictive for the expansion of this deployment model?
EIGRP
IS-IS
OSPF
BGP
Which actions are performed at the distribution layer of the three-layer hierarchical network design model? (Choose two)
Fast transport
Reliability
QoS classification and marking boundary
Fault isolation
Redundancy and load balancing
