質問 112
Refer to the exhibit.
SwitchC connects HR and Sales to the Core switch However, business needs require that no traffic from the Finance VLAN traverse this switch Which command meets this requirement?
A)
B)
C)
D)
- A. Option D
- B. Option B
- C. Option A
- D. Option C
正解: A
解説:
From the "show vlan brief" we learn that Finance belongs to VLAN 110 and all VLANs (from 1 to
1005) are allowed to traverse the trunk (port-channel 1). Therefore we have to remove VLAN 110 from the allowed VLAN list with the "switchport trunk allowed vlan remove " command. The pruning feature cannot do this job as Finance VLAN is active.
質問 113
Refer to the exhibit.
Link1 is a copper connection and Link2 is a fiber connection. The fiber port must be the primary port for all forwarding. The output of the show spanning-tree command on SW2 shows that the fiber port is blocked by spanning tree. An engineer enters the spanning- tree port-priority 32 command on GO/1 on SW2, but the port remains blocked. Which command should be entered on the ports that are connected to Link2 to resolve the issue?
- A. Enter spanning-tree port-priority 32 on SW1.
- B. Enter spanning-tree port-priority 64 on SW2.
- C. Enter spanning-tree port-priority 224 on SW1.
- D. Enter spanning-tree port-priority 4 on SW2.
正解: A
質問 114
Refer to the exhibit.
What is the result when a switch that is running PVST+ is added to this network?
- A. Both switches operate in the PVST+ mode
- B. Spanning tree is disabled automatically on the network
- C. Both switches operate in the Rapid PVST+ mode.
- D. DSW2 operates in Rapid PVST+ and the new switch operates in PVST+
正解: D
解説:
Explanation
From the output we see DSW2 is running in RSTP mode (in fact Rapid PVST+ mode as Cisco does not support RSTP alone). When a new switch running PVST+ mode is added to the topology, they keep running the old STP instances as RSTP (in fact Rapid PVST+) is compatible with PVST+.
質問 115
Which EIGRP feature allows the use of leak maps?
- A. neighbor
- B. stub
- C. offset-list
- D. address-family
正解: B
解説:
Explanation
If we configured an EIGRP stub router so that it only advertises connected and summary routes.
But we also want to have an exception to this rule then we can configure a leak-map. For example:
R4(config-if)#router eigrp 1
R4(config-router)#eigrp stub
R4(config)#ip access-list standard R4_L0opback0
R4(config-std-nacl)#permit host 4.4.4.4
R4(config)#route-map R4_L0opback0_LEAKMAP
R4(config-route-map)#match ip address R4_L0opback0
R4(config)#router eigrp 1
R4(config-router)#eigrp stub leak-map
As we can see the leak-map feature goes long with 'eigrp stub' command.
質問 116
Which control plane protocol is used between Cisco SD-WAN routers and vSmart controllers?
- A. OMP
- B. TCP
- C. BGP
- D. UDP
正解: A
解説:
Cisco SD-WAN uses Overlay Management Protocol (OMP) which manages the overlay network. OMP runs between the vSmart controllers and WAN Edge routers (and among vSmarts themselves) where control plane information, such as the routing, policy, and management information, is exchanged over a secure connection.

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. It issues email when the value is greater than 75% for five polling cycles.
- B. Upon the value reaching 75%, a SNMP event is generated and sent to the trap server.
- C. It reads an SNMP variable, and when the value exceeds 75% for live polling cycles.
- D. It presents a SNMP variable that can be interrogated.
正解: C
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)

When configuration WPA2 Enterprise on a WLAN, which additional security component configuration is required?
- A. PKI server
- B. NTP server
- C. RADIUS server
- D. TACACS server
正解: C
解説:
Deploying WPA2-Enterprise requires a RADIUS server, which handles the task of authenticating network users access. Theactual authentication process is based on the 802.1X policy and comes in several different systems labelled EAP. Becauseeach device is authenticated before it connects, a personal, encrypted tunnel is effectively created between the device andthe network.
質問 127
Drag and drop the characteristics from the left onto the routing protocols they describe on the right.
正解:
解説:
Explanation
EIGRP maintains alternative loop-free backup via the feasible successors. To qualify as a feasible successor, a router must have an Advertised Distance (AD) less than the Feasible distance (FD) of the current successor route.
Advertised distance (AD): the cost from the neighbor to the destination. Feasible distance (FD): The sum of the AD plus the cost between the local router and the next-hop router

ip route vrf Customer 192.168.1.200 255.255.255.255 192.168.1.1 global
ip route 192.168.1.0 255.255.255.0 Vlan10
ip route 172.16.1.0 255.255.255.0 Vlan20 - C. ip route vrf Customer1 172.16.1.0 255.255.255.0 172.16.1.1 Customer1
ip route vrf Customer 192.168.1.200 255.255.255.255 192.168.1.1 Customer2 - D. ip route vrf Customer1 172.16.1.1 255.255.255.255 172.16.1.1 global
ip route vrf Customer 192.168.1.200 255.255.255.0 192.168.1.1 global
ip route 192.168.1.0 255.255.255.0 Vlan10
ip route 172.16.1.0 255.255.255.0 Vlan20
正解: B
解説:
https://www.cisco.com/c/en/us/support/docs/ip/ip-routing/200158-Configure-Route-Leaking-between-Global-a.html
Static routes directly between VRFs are not supported so we cannot configure a direct static route between two VRFs.
The command "ip route vrf Customer1 172.16.1.0 255.255.255.0 172.16.1.1 global" means in VRF Customer1, in order to reach destination 172.16.1.0/24 then we uses the next hop IP address 172.16.1.1 in the global routing table. And the command "ip route 192.168.1.0 255.255.255.0 Vlan10" tells the router "to reach 192.168.1.0/24, send to Vlan 10".

Refer to the exhibit.
An engineer must create a configuration that executes the show run command and then terminates the session when user CCNP legs in. Which configuration change is required''
- A. Add the access-class keyword to the username command
- B. Add the autocommand keyword to the username command
- C. Add the access-class keyword to the aaa authentication command
- D. Add the autocommand keyword to the aaa authentication command
正解: B
解説:
Explanation
The autocommand causes the specified command to be issued automatically after the user logs in. When the command is complete, the session is terminated. Because the command can be any length and can contain embedded spaces, commands using the autocommand keyword must be the last option on the line. In this specific question, we have to enter this line username CCNP autocommand show running-config.
