Demo Questions

Question 1
  
Refer to the exhibit. As the new network designer for a manufacturing company, you are designing this resilient Ethernet ring for the plant Ethernet network that is connected to the core, which does not use STP. Both edge ports are on the same switch in a ring segment. There is connectivity between the edge ports throughout the segment, so you create a redundant connection between any two switches in the ring. Which four options are characteristics of this design? (Choose four.)
  1. If a link fails, then the alternate ports quickly unblock. When the failed ink comes back up, a physically blocked port per VLAN is selected with minimal disruption to the network.
  2. If a link fails, then the alternate portsquickly unblock. Whenthe failed ink comes back up, a logically blocked port per VLAN is selected with minimal disruption to the network.
  3. If VLAN load balancing is configured, then two ports in the segment control the blocked state of VLANs.
  4. If VLAN load balancing is configured, then one port in the segment controls the blocked state of VLANs.
  5. If all ports in the segment are operational, then one port is in the blocked state for each VLAN.
  6. If one or more ports in a segment are not operational, thereby causing a linkfailure, then all ports forward traffic on all VLANs to ensure connectivity.
  7. If all ports in the segment are operational, then two ports are in the blocked state for each VLAN.
Correct answer: BCEF
Explanation:
REP segments have thefollowing characteristics:If all ports in a segment are operational, one port (referred to as the alternate port) is in the blocked state for each VLAN. If VLAN load balancing is configured, two ports in the segment control the blocked state of VLANs. If one or more ports in a segment is not operational, and cause a link failure, all ports forward traffic on all VLANs to ensure connectivity. In case of a link failure, alternate ports are unblocked as quickly as possible. When the failed link is up, a logically blocked portper VLAN is selected with minimal disruption to the network. 
REP segments have thefollowing characteristics:
  • If all ports in a segment are operational, one port (referred to as the alternate port) is in the blocked state for each VLAN. If VLAN load balancing is configured, two ports in the segment control the blocked state of VLANs. 
  • If one or more ports in a segment is not operational, and cause a link failure, all ports forward traffic on all VLANs to ensure connectivity. 
  • In case of a link failure, alternate ports are unblocked as quickly as possible. When the failed link is up, a logically blocked portper VLAN is selected with minimal disruption to the network. 
Question 2
Refer to the exhibit. 
  
A service provider would like to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP-SW2. In which two of these ways can you design this solution? (Choose two.)
  1. Enable Y.1731 Connectivity Fault Management on the SP switches.
  2. E-LMI PDUs must be forwarded over VPLS.
  3. Cisco Discovery Protocol PDUs must be forwarded over the VPLS.
  4. Use upward maintenance endpoints on the SP switches.
  5. Enable IEEE 802.1ag Connectivity Fault Management on the SP switches.
Correct answer: DE
Question 3
Company ABC is using an Ethernet virtual circuit as it’s provider’s DCI solution. A goal is to reduce the time to detect the link failure. Which protocol accomplishes this goal?
  1. UDLP
  2. spanning tree bridge assurance
  3. link aggregation group
  4. Ethernet OAM
Correct answer: D
Question 4
  
Refer to the exhibit. 
This Layer 2 network is expected to add 150 VLANs over the next year, in addition to the existing 50 VLANs within the network. Which STP type will support this design requirement using the least amount of CPU resources and achieving load-balancing?
  1. MST
  2. CST
  3. PVST+
  4. RSTP
Correct answer: A

Question 5
When creating a network design, which one of these options provides for basic Layer 2 client isolation to prevent broadcast traffic exposure?
  1. SVI
  2. VLAN
  3. routed port
  4. edge port
Correct answer: B
Question 6
What are two design advantages to using virtual port channel? (Choose two.)
  1. enhanced system availability through multiple systems
  2. reduced Spanning Tree Protocol convergence time
  3. loop management without use of Spanning Tree Protocol
  4. ability to use Spanning Tree Protocol blockedports to forward traffic
  5. enhanced abilityto recover from Spanning Tree Protocol changes
Correct answer: AC
Question 7
You are designing a wireless LAN with the following components:
  • High-densityindoor access point deployment 
  •  2.4-GHz and 5-GHz radios 
  •  802.11a, 802.11g,and 802.11n mode wireless LAN clients 
Site survey results show negligible foreign WiFi and non-WiFi interference. What is the best method to decrease duty cycle (radio frequency utilization) and increase overall wireless LAN client performance for this design?
  1. Disable all data rates below 12 Mb/s on all access points.
  2. Decrease radio transmit power on all access points that report a high duty cycle.
  3. Increase radio transmit power on all access points that report a high duty cycle.
  4. Disable all data rates above 12 Mb/s on all access points.
  5. Increase radio transmit power on all access points.
Correct answer: A
Question 8
You are designing a network solution to connect a primary data center to a disaster recovery site. The applications hosted on the site will be mainly web and email servers that are provided through a virtualized environment. A third data center facility may also be added in the next six months. Which connectivity type is appropriate for this design?
  1. L2TPv3
  2. VPLS
  3. point-to-point GRE tunnels
  4. VPWS
Correct answer: B
Question 9
Which option is a critical mechanism to optimize convergence speed when using MPLS FRR?
  1. IGP timers
  2. bandwidth reservation
  3. shared risk link groups
  4. down detection
Correct answer: D
Question 10
Which design criteria drives the selection of G.8032 in an ISP network design?
  1. To gradually degrade the Ethernet rings’ performance when it becomes saturated.
  2. To make full use of Ethernet rings’ redundant paths.
  3. To achieve fast failover between two upstream Ethernet ring paths to the network core.
  4. To prevent loops on Ethernet rings.
Correct answer: D
