Demo Questions

Question 1
Which three commands can you use to configure VXLAN on a Cisco ASA firewall? (Choose three.)

  • A: default-mcast-group
  • B: set ip next-hop verify-availability
  • C: sysopt connection tcpmss
  • D: segment-id
  • E: inspect vxlan
  • F: nve-only
Correct Answer: ADF



Question 2
Which Cisco ISE profiler service probe can collect information about Cisco Discovery Protocol?

  • A: SNMP Query
  • B: DCHP SPAN
  • C: DCHP
  • D: HTTP
  • E: RADIUS
  • F: NetFlow
Correct Answer: F



Question 3
View the Exhibit. 

  

Refer to the exhibit. After you applied this EtherChannel configuration to a Cisco ASA, the EtherChannel failed to come up. 
Which reason for the problem is the most likely?

  • A: The channel-group modes are mismatched.
  • B: The lacp system-priority and lacp port-priority values are the same.
  • C: The EtherChannel requires three ports, and only two are configured.
  • D: The EtherChannel is disabled.
Correct Answer: C



Question 4
Which option best describes RPL?

  • A: RPL stands for Routing over Low-power Lossy Networks that use link-state LSAs to determine the best route between leaves and the root border router.
  • B: RPL stands for Routing over Low-power Lossy Networks that use distance vector DOGAG to determine the best route leaves and the root border router.
  • C: RPL stands for Routing over low priority links that use link-state LSAs to determine the best route between two root border routers.
  • D: RPL stands for Routing overlow priority links that use distance vector DOGAG to determine the best route between two root border routers.
Correct Answer: B
RPL is a distance vector protocol and supports a wide set of routing link and node metrics. RPL supports mono metric optimization—the best path is considered as the shortest (constrained) path according to a single metric (multimetric optimization is not supported). The objective is to not trade path optimality for network stability. A small path cost increase is usually smoothed out for the benefit of limiting the control plane traffic.

Question 5
Which WEP configuration can be exploited by a weak IV attack?

  • A: When the static WEP password has been given away
  • B: When the static WEP password has been stored without encryption
  • C: When a per-packet WEP key is in use
  • D: When a 40-bit key is in use
  • E: When the same WEP key is used to create every packet
  • F: When a 64-bit key is in use
Correct Answer: D

Question 6
Which two options are benefits of global ACLs? (Choose two.)

  • A: The only operate on logical interfaces.
  • B: They are more efficient because they are processed before interface access rules.
  • C: They can be applied to multiple interfaces.
  • D: They are flexible because they match source and destination IP addresses for packets that arrive on any interface.
  • E: They save memory because they work without being replicated on each interface.
Correct Answer: DE
Global access rules allow you to apply a global rule to ingress traffic without the need to specify an interface to which the rule must be applied. Using global access rules provides the following benefits:
When migrating to the adaptive security appliance from a competitor appliance, you can maintain a global access rule policy instead of needing to apply an interface-specific policy on each interface. 
Global access control policies are not replicated on each interface, so they save memory space. 
Global access rules provides flexibility in defining a security policy. You do not need to specify which interface a packet comes in on, as long as it matches the source and destination IP addresses. 
Global access rules use the same mtrie and stride tree as interface-specific access rules, so scalability and performance for global rules are the same as for interface-specific rules.

Question 7
Which three statements about 802.1x multiauthentication mode are true? (Choose three.)

  • A: It can be deployed in conjunction with MDA functionality on voice VLANs.
  • B: It requires each connected client to authenticate individually.
  • C: Each multiauthentication port can support only one voice VLAN.
  • D: It is recommended for auth-fail VLANs.
  • E: On non-802.1x devices, it can support only one authentication method on a single port.
  • F: It is recommended for guest VLANs.
Correct Answer: ABC
Available in Cisco IOS Release 12.2(50)SG, multiauthentication mode allows one client on the voice VLAN and multiple authenticated clients on the data VLAN. When a hub or access point is connected to an 802.1X port, multiauthentication mode provides enhanced security over multiple-hosts mode by requiring authentication of each connected client. For non-802.1X devices, you can use MAB or web-based authentication as the fallback method for individual host authentications, allowing you to authenticate different hosts through different methods on a single port.  
Multiauthentication also supports MDA functionality on the voice VLAN by assigning authenticated devices to either a data or voice VLAN depending on the VSAs received from the authentication server.

  • B:
      
  • C:
      
  • D:
      
  • E:

Question 9
You are considering using RSPAN to capture traffic between several switches. 
Which two configurations aspects do you need to consider? (Choose two.)

  • A: Not all switches need to support RSPAN for it to work
  • B: The RSPAN VLAN need to be blocked on all trunk interfaces leading to the destination RSPAN switch
  • C: All switches need to be running the same IOS version
  • D: All distribution switches need to support RSPAN
  • E: The RSPAN VLAN need to be allow on all trunk interfaces leading to the destination RSPAN switch
Correct Answer: DE
