Part 7 Flashcards
What is a benefit of deploying an on-premises infrastructure versus a cloud infrastructure deployment?
A. ability to quickly increase compute power without the need to install additional hardware
B. less power and cooling resources needed to run infrastructure on-premises
C. faster deployment times because additional infrastructure does not need to be purchased
D. lower latency between systems that are physically located near each other
D. lower latency between systems that are physically located near each other
How does QoS traffic shaping alleviate network congestion?
A. It drops packets when traffic exceeds a certain bitrate.
B. It buffers and queues packets above the committed rate.
C. It fragments large packets and queues them for delivery.
D. It drops packets randomly from lower priority queues.
B. It buffers and queues packets above the committed rate. https://www.cisco.com/c/en/us/support/docs/quality-of-service-qos/qos-policing/19645-policevsshape.html
In a Cisco SD-Access wireless architecture, which device manages endpoint ID to edge node bindings?
A. fabric control plane node
B. fabric wireless controller
C. fabric border node
D. fabric edge node
A. fabric control plane node
In a Cisco SD-Access solution, what is the role of a fabric edge node?
A. to connect external Layer 3 networks to the SD-Access fabric
B. to connect wired endpoints to the SD-Access fabric
C. to advertise fabric IP address space to external networks
D. to connect the fusion router to the SD-Access fabric
B. to connect wired endpoints to the SD-Access fabric
What are two reasons a company would choose a cloud deployment over an on-prem deployment? (Choose two.)
A. Cloud costs adjust up or down depending on the amount of resources consumed. On-prem costs for hardware, power, and space are on-going regardless of usage.
B. Cloud resources scale automatically to an increase in demand. On-prem requires additional capital expenditure.
C. In a cloud environment, the company is in full control of access to their data. On-prem risks access to data due to service provider outages.
D. In a cloud environment, the company controls technical issues. On-prem environments rely on the service provider to resolve technical issues.
E. Cloud deployments require long implementation times due to capital expenditure processes. On-prem deployments can be accomplished quickly using operational expenditure processes.
A. Cloud costs adjust up or down depending on the amount of resources consumed. On-prem costs for hardware, power, and space are on-going regardless of usage.
B. Cloud resources scale automatically to an increase in demand. On-prem requires additional capital expenditure.
What is the difference between the MAC address table and TCAM?
A. TCAM is used to make L2 forwarding decisions. CAM is used to build routing tables.
B. Router prefix lookups happen in TCAM. MAC address table lookups happen in CAM.
C. The MAC address table supports partial matches. TCAM requires an exact match.
D. The MAC address table is contained in TCAM. ACL and QoS information is stored in TCAM.
D. The MAC address table is contained in TCAM. ACL and QoS information is stored in TCAM.
Which controller is the single plane of management for Cisco SD-WAN? A. vBond B. vSmart C. vManage D. vEdge
C. vManage
A company plans to implement intent-based networking in its campus infrastructure. Which design facilitates a migration from a traditional campus design to a programmable fabric design?
A. two-tier
B. Layer 2 access
C. three-tier
D. routed access
A. two-tier
Explanation: Intent-based Networking (IBN) transforms a hardware centric, manual network into a controller-led network that captures business intent and translates it into policies that can be automated and applied consistently across the network. The goal is for the network to continuously monitor and adjust network performance to help assure desired business outcomes. IBN builds on software-defined networking (SDN). SDN usually uses spine-leaf architecture, which is typically deployed as two layers: spines (such as an aggregation layer), and leaves (such as an access layer).
Which statement about a fabric access point is true?
A. It is in local mode and must be connected directly to the fabric edge switch.
B. It is in local mode and must be connected directly to the fabric border node.
C. It is in FlexConnect mode and must be connected directly to the fabric border node.
D. It is in FlexConnect mode and must be connected directly to the fabric edge switch.
A. It is in local mode and must be connected directly to the fabric edge switch.
A customer requests a network design that supports these requirements: ✑ FHRP redundancy ✑ multivendor router environment ✑ IPv4 and IPv6 hosts Which protocol does the design include?
A. VRRP version 2
B. VRRP version 3
C. GLBP
D. HSRP version 2
B. VRRP version 3
While configuring an IOS router for HSRP with a virtual IP of 10.1.1.1, an engineer sees this log message. Jan 1 12:12:12.111 : %HSRP-4-DIFFVIP1: GigabitEthernet0/0 Grp 1 active routers virtual IP address 10.1.1.1 is different to the locally configured address 10.1.1.25 Which configuration change must the engineer make?
A. Change the HSRP group configuration on the local router to 1.
B. Change the HSRP virtual address on the local router to 10.1.1.1.
C. Change the HSRP virtual address on the remote router to 10.1.1.1.
D. Change the HSRP group configuration on the remote router to 1.
B. Change the HSRP virtual address on the local router to 10.1.1.1.
A network administrator has designed a network with two multilayer switches on the distribution layer, which act as default gateways for the end hosts. Which two technologies allow every end host in a VLAN to use both gateways? (Choose two.)
A. VRRP
B. GLBP
C. VSS
D. MHSRP
E. HSRP
A. GLBP
D. MHSRP (multi-group HSRP)
