Explanation
https://www.cisco.com/c/en/us/td/docs/security/firepower/fxos/clustering/asa-cluster-solution.html Clustering lets you group multiple Firepower Threat Defense (FTD) units together as a single logical device.
Clustering is only supported for the FTD device on the Firepower 9300 and the Firepower 4100 series. A cluster provides all the convenience of a single device (management, integration into a network) while achieving the increased throughput and redundancy

- B. A TACACS+server is checked first. If that check fail, a RADIUS server is checked. If that check fail. a local database is checked.
- C. A local database is checked first. If that fails, a TACACS+server is checked, if that check fails, a RADUIS server is checked.
- D. A local database is checked first. If that check fails, a TACACS+server is checked.
正解：D

Explanation
The "aaa authentication login default local group tacacs+" command is broken down as follows:
+ The 'aaa authentication' part is simply saying we want to configure authentication settings.
+ The 'login' is stating that we want to prompt for a username/password when a connection is made to the device.
+ The 'default' means we want to apply for all login connections (such as tty, vty, console and aux). If we use this keyword, we don't need to configure anything else under tty, vty and aux lines. If we don't use this keyword then we have to specify which line(s) we want to apply the authentication feature.
+ The 'local group tacacs+" means all users are authenticated using router's local database (the first method). If the credentials are not found on the local database, then the TACACS+ server is used (the second method).
When you click Deploy, Cisco DNA Center requests the Cisco Identity Services Engine (Cisco ISE) to send notifications about the policy changes to the network devices.

質問 # 307
What mechanism does PIM use to forward multicast traffic?
- A. PIM sparse mode uses receivers to register with the RP.
- B. PIM dense mode uses a pull model to deliver multicast traffic.
- C. PIM sparse mode uses a pull model to deliver multicast traffic.
- D. PIM sparse mode uses a flood and prune model to deliver multicast traffic.
正解：C
解説：
PIM dense mode (PIM-DM) uses a push model to flood multicast traffic to every corner of the network. This push model is a brute-force method of delivering data to the receivers. This method would be efficient in certain deployments in which there are active receivers on every subnet in the network. PIM-DM initially floods multicast traffic throughout the network. Routers that have no downstream neighbors prune the unwanted traffic. This process repeats every 3 minutes.
PIM Sparse Mode (PIM-SM) uses a pull model to deliver multicast traffic. Only network segments with active receivers that have explicitly requested the data receive the traffic. PIM-SM distributes information about active sources by forwarding data packets on the shared tree. Because PIM-SM uses shared trees (at least initially), it requires the use of an RP. The RP must be administratively configured in the network.
Answer C seems to be correct but it is not, PIM spare mode uses sources (not receivers) to register with the RP. Sources register with the RP, and then data is forwarded down the shared tree to the receivers.

What does this EEM applet event accomplish?
"event snmp oid 1.3.6.1.3.7.1.5.1.2.4.2.9 get-type next entry-op g entry-val 75 poll-interval 5"
- A. Upon the value reaching 75%, a SNMP event is generated and sent to the trap server.
- B. It reads an SNMP variable, and when the value exceeds 75% for live polling cycles.
- C. It presents a SNMP variable that can be interrogated.
- D. It issues email when the value is greater than 75% for five polling cycles.
正解：B
解説：
EEM offers the ability to monitor events and take informational or corrective action when the monitored events occur or reach a threshold. An EEM policy is an entity that defines an event and the actions to be taken when that event occurs. There are two types of EEM policies: an applet or a script. An applet is a simple form of policy that is defined within the CLI configuration.
To specify the event criteria for an Embedded Event Manager (EEM) applet that is run by sampling Simple Network Management Protocol (SNMP) object identifier values, use the event snmp command in applet configuration mode.
event snmp oid oid-value get-type {exact | next} entry-op operator entry-val entryvalue
[exit-comb {or | and}] [exit-op operator] [exit-val exit-value] [exit-time exit-timevalue] poll-interval poll-int-value
+ oid: Specifies the SNMP object identifier (object ID)
+ get-type: Specifies the type of SNMP get operation to be applied to the object ID specified by the oid-value argument.
- next - Retrieves the object ID that is the alphanumeric successor to the object ID specified by the oid-value argument.
+ entry-op: Compares the contents of the current object ID with the entry value using the specified operator. If there is a match, an event is triggered and event monitoring is disabled until the exit criteria are met.
+ entry-val: Specifies the value with which the contents of the current object ID are compared to decide if an SNMP event should be raised.
+ exit-op: Compares the contents of the current object ID with the exit value using the specified operator. If there is a match, an event is triggered and event monitoring is reenabled.
+ poll-interval: Specifies the time interval between consecutive polls (in seconds) Reference:
QUESTION 2 Cisco TrustSec uses tags to represent logical group privilege. This tag, called a Security Group Tag (SGT), is used in access policies. The SGT is understood and is used to enforce traffic by Cisco switches, routers and firewalls . Cisco TrustSec is defined in three phases: classification, propagation and enforcement.
When users and devices connect to a network, the network assigns a specific security group. This process is called classification. Classification can be based on the results of the authentication or by associating the SGT with an IP, VLAN, or port-profile (-> Answer 'security group tag ACL assigned to each port on a switch' and answer 'security group tag number assigned to each user on a switch' are not correct as they say "assigned ... on a switch" only. Answer 'security group tag ACL assigned to each router on a network' is not correct either as it says "assigned to each router").
