Free Cisco 300-410 Practice Questions 2026 | Implementing Cisco Enterprise Advanced Routing and Services (300-410 ENARSI)

Refer to the exhibit.

R1 has a route map configured, which results in a loss of partial IPv6 prefixes for the BGP neighbor, resulting in service degradation. How can the full service be restored?

A.

The neighbor requires a soft reconfiguration, and this will clear the policy without resetting the BGP TCP connection.

B.

The prefix lit requires all prefixes that R1 is advertising to be added to it, and this will allow additional prefixes to be advertised.

C.

The route map requires a deny 20 statement without set conditions, and this will allow additional prefixes to be advertised.

D.

The route map requires a permit 20 statement without set conditions, and this will allow additional prefixes to be advertised.

What is an advantage of implementing BFD?

A.

BFD provides faster updates for any flapping route.

Refer to the exhibit The enterprise users fail to authenticate with the TACACS server when a direct fiber link fails between RB and RD The NOC team observes 
Users connected on AS65201 fail to authenticate with TACACS server 192 168 1
1
Users connected on AS65101 successfully authenticate with TACACS server 192

Refer to lhe exhibit An engineer must filter EIGRP updates that are received to block all 10 10 10.0/24 prefixes The engineer tests the distribute list and finds one associated prefix. Which action resolves the issue?

A.

There is a permit in the route map that allows this prefix A deny 20 statement is required with a match condition to match a new ACL that denies all prefixes

B.

There is a permit in the ACL that allows this prefix into EI6RP. The ACL should be modified to deny 10.10.10.0 0.0.0.255.

C.

There is a permit in the route map that allows this prefix A deny 20 statement is required with no match condition to block the prefix.

D.

There is a permit in the ACL that allows this prefix into EIGRP. The ACL should be modified to deny 10.10.10.0 255.255.255.0.

Refer to the exhibit.

Which action restores OSPF adjacency between R1 and R2?

A.

Change the IP MTU of R1 Fa1/0 to 1300

B.

Change the IP MTU of R2 Fa0/0 to 1300

C.

Change the IP MTU of R1 Fa1/0 to 1500

D.

Change the IP MTU of R2 Fa0/0 to 1500

The network administrator must implement IPv6 in the network to allow only devices that not only have registered IP addresses but are also connecting from assigned locations. Which security feature must be implemented?

A.

IPv6 Snooping

B.

IPv6 Destination Guard

C.

IPv6 Prefix Guard

D.

IPv6 Router Advertisement Guard

The network administrator is tasked to configure R1 to authenticate telnet connections based on Cisco ISE using RADIUS. ISE has been configured with an IP address of 192.168.1.5 and with a network device pointing towards R1 (192.168.1.1) with a shared secret password of Cisco123. If ISE is down, the administrator should be able to connect using the local database with a username and password combination of admin/cisco123.

The administrator has configured the following on R1:

A.

Option A

B.

Option B

C.

Option C

D.

Option D
