An enterprise has identified these causes for inefficient CAPEX spending:
CAPEX planning is driven by technology and not by business objectives. The CAPEX planning team lacks the data it needs to perform due diligence tasks. The organizational structure lacks sufficient accountability and incentives.
Which corporate cultural change contributes to improving the effectiveness of CAPEX spending?
A. Build a financial control function that delivers high-quality reports on operational expenses for business insight and financial reporting.
B. CxO-level staff must have a full technical understanding but the should not trust their technical leaders fully.
C. Adopt new organizational models that promote real accountability for ROI. not just revenue. EBITDA, and cash.
D. Marketing and product management divisions must reduce their CAPEX budgets significantly to drive the change.
An enterprise wants to provide low-cost delivery of network systems that can be scaled on business demand, followed by an initiative to reduce capital expenses for new IT equipment. Which technology meets these goals'?
A. laaS within a private cloud
B. laaS within an on-premises location
C. PaaS within a public cloud
D. SaaS within an on-premises location
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 core layer, to offer the possibility to isolate STP domains
B. at the aggregation layer because it is the Layer 2 to Layer 3 demarcation point
C. at the access layer because the STP root bridge does not need to align with the HSRP active node
D. at the core layer because all external connections must terminate there for security reasons
Company XYZ runs OSPF in their network. A design engineer decides to implement hot- potato routing architecture. How can this implementation be achieved?
A. Enable iBGP and apply prepend to ensure all prefixes will have the same length of the AS path attribute value.
B. Redistribute the external prefixes onto OSPF and ensure the total metric calculation includes only the ext value and the value is the same in all ASBRs.
C. Enable OSPF load-balancing over unequal cost path.
D. Redistribute the external prefixes onto OSPF and ensure that the total metric calculation includes external internal values.
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
Company XYZ is redesigning their QoS policy. Some of the applications used by the company are real-time applications. The QoS design must give these applications preference in terms of transmission. Which QoS strategy can be used to fulfill the requirement?
A. weighted fair queuing
B. weighted random early detection
C. low-latency queuing
D. first-in first-out
What are two primary design constraints when a robust infrastructure solution is created? (Choose two.)
A. monitoring capabilities
B. project time frame
C. staff experience
D. component availability
E. total cost
Which effect of using ingress filtering to prevent spoofed addresses on a network design is true?
A. It reduces the effectiveness of DDoS attacks when associated with DSCP remarking to Scavenger.
B. It protects the network Infrastructure against spoofed DDoS attacks.
C. It Classifies bogon traffic and remarks it with DSCP bulk.
D. It filters RFC 1918 IP addresses.
Sometimes SDN leverages various overlay networking technologies to create layer(s) of network abstraction. What describes an overlay network?
A. It transmits packets that traverse over network devices like switches and routers
B. It encapsulates packets at source and destination, which incurs additional overhead
C. Packet delivery and reliability occurs at Layer 3 and Layer 4
D. It is responsible for the delivery of packets; NAT- or VRF-based segregation is required
A business wants to refresh its legacy Frame Relay WAN. It currently has product specialists in each of its 200 branches but plans to reduce and consolidate resources. The goal is to have product specialists available via video link when customers visit the nationwide branch offices. Which technology should be used to meet this objective?
A. DMVPN phase 1 network over the Internet
B. Layer 3 MPLS VPN hub and spoke
C. Layer2VPLS
D. Layer 3 MPLS VPN full mesh
