Demo Questions

Question 1
Your campus EX9200 core devices are highly oversubscribed on bandwidth ans reporting massive dropped packets. To immediately address the issue, you decide to implement shaping on all interfaces. Which action will accomplish?
  1. Apply the input-shape-rate 5G parameter to all interfaces under the [edit class-of service] hierarchy.
  2. Define a CoS input traffic control profile with the shape-rate 5G parameter and apply it to all interfaces.
  3. Define a CoS output traffic control profile with the shape-rate 5G parameter and apply it to all interfaces.
  4. Apply the shape-rate 5G parameter to all interfaces under the [edit class-of service] hierarchy.
Correct answer: C
Question 2
What allows non-Web enabled devices to access the network on a port configured for captive portal?
  1. A MAC address white list can be configured on the switch to allow specific MAC addresses to bypass the captive portal process.
  2. LLDP can be used to query the type of device that is attempting to access the network, and predefined device types can be allowed to bypass the captive portal process.
  3. Captive portal can be configured to only prompt for credentials when HTTP or HTTPS traffic is requested on a port to allow on-HTTP enabled devices access to the network.
  4. Authentication credentials for specific devices can be preconfigured on the switch for automatic authentication.
Correct answer: A
Question 3
You have deployed sparce-mode multicast in your network using the IGP metrics shown in the exhibit.       
Which path will (*,G) traffic follow form the source to the receiver before the (S,G) state is registered?
  1. Source, R1, R4, R5, R6, Receiver
  2. Source, R1, R2, R5, R2, R3, R6, Receiver
  3. Source, R1, R2, R3, R6, Receiver
  4. Source, R1, R2, R5, R6, Receiver
Correct answer: B
Question 4
You are troubleshooting an OSPF adjacency issue between R1 and R2. What is the reason for the ExStart state shown in the exhibit?  
 
  1. R2 was elected as the designated router.
  2. R1 was elected as the backup designated router.
  3. R1 and R2 are using the same IP address. 
  4. The MTU is not the default on R1 and R2.
Correct answer: C
Question 5
Router R1, in peer AS 65001, advertises routes to R2 using EBGP. R2 advertises the routes learned from R1 to R3 using IBGP. Referring to the exhibit, to which routers will R3 advertise the BGP routes received from R2?  
  
  1. R6, R7
  2. R4, R5, R6, R7
  3. R4, R5
  4. R2, R4, R5, R6, R7
Correct answer: C
Question 6
Referring to the exhibit, which statement is true? 
 
  1. R1 is an ASBR.
  2. R1 has the 8 bit set.
  3. R1 is a backbone router.
  4. R1 is an ABR.
Correct answer: A
Question 7
Which two statements are true about PIM source-specific multicast (SSM)? (Choose two.)
  1. The receiver DR builds a source-base tree to the RP.
  2. (S,G) is always used.
  3. A Different group address must be used by each source.
  4. IGMPv3 is required.
Correct answer: BD
Question 8
You are configuring MSTP to prevent loops in your Layer 2 network. After applying the configuration, you notice that MSTO is not working correctly. Referring to the exhibit, what is causing the problem?  
  
  1. Too many VLANs have been defined.
  2. Context identifier must be specified.
  3. MSTI-to-VLAN mappings must be the same.
  4. Incorrect revision number is used.
Correct answer: C
Question 9
A customer on MSTI-2 was isolated due to a physical link outage on Switch 5's ge-0/0/32 interface.  
Referring to the exhibit, which corrective action would solve this problem?  
 
  1. Replace the link between Switch 5 and Switch 6 with a 10 Gbps link.
  2. Implement the CIST on all switches.
  3. Move the root bridge for MSTI-2 to Switch 6.
  4. Add MSTI-2 to all interfaces on Switch 5.
Correct answer: D
Question 10
Which two statements about MVRP are correct? (Choose two.)
  1. MVRP monitors interfaces using VSTP and dynamically creates VLANs as necessary.
  2. MVRP PDUs are sent to other switches as periodic intervals.
  3. MVRP can propagate dynamic VLANs created on one switch to another switch.
  4. MVRP is enabled by adding trunk ports under the [edit protocols mvrp] hierarchy.
Correct answer: BD
