Free Cisco 300-510 Practice Questions 2026 | 300-510

Which two differences should be considered when deciding whether to implement to implement routing policies or route maps? (Choose two.)

A. Sequences are added after implementing a route map, but routing policies must be reconfigured when change is needed.

B. Route maps are implemented using hierarchical policies, but routing policies must be implemented sequentially.

C. Route maps require an explicit deny at the end of the sequence, but routing policies have an implicit deny at the end of the program.

D. Route policies require sequence numbers, but route maps are implemented without sequencing.

E. Route maps are supported in Cisco 10S Software and routing policies are supported in Cisco IOS XR Software.

Refer to the exhibit.

BGP is running on the network, and CE1 currently prefers routes to the internet via PE 1 A network engineer must manipulate the BGP routes that CE1 receives from PE2 to be more desirable The engineer configured a route map using MED and applied it on CE1 outbound from PE2. However, after a BGP soft reset. PE1 is still preferred. Which action must the engineer take so that PE2 is chosen as the next hop?

A. Update the route map to use only weight to manipulate the path.

B. Configure the route map with MED and local preference to manipulate the route outbound

C. Apply the route map on CE1 In the inbound direction.

D. Configure the route map with AS path prepend to manipulate the AS path to exit the autonomous system

What is one of the purposes of a default Multicast Distribution Tree?

A. to offload traffic from data MDT

B. to define the RP for PIM sparse mode and the different leafs

C. to support control traffic between different VRFs

D. to handle high-bandwidth source streams

Which feature is used in multicast routing to prevent loops?

A. STP

B. inverse ARP

C. RPF

D. split horizon

Refer to the exhibit.

MPLS traffic from 192.168.4.0/24 to 192.168.5.0/24 is failing to pass over the link from R4 to R2. The engineer verified that:

Cisco Express Forwarding Is enabled on all routers.
All routers reach all networks via OSPF.
MPLS traffic from 192.168.1.0/24 to 192.168.3.0/24 is passing normally over the link from R1 to R2.
Which action resolves the issue?

A. On router R4, remove the mpls ip command on the s/O/O/2 interface.

B. On router R2, configure the mpls ip command on the SIO/O/4 interface.

C. On router R4, configure the mpls label protocol Idp command on all serial interfaces.

D. On router R2, configure the mpls label protocol Idp command on the interface.

What are two features of dual-stack? (Choose two.)

A. It is implemented without excessive processing power.

B. It supports IPv4 and IPv6 traffic on the same infrastructure.

C. It allows an engineer to stack multiple Layer 2 switches to serve as a single switching unit.

D. It requires tunneling IPv6 traffic over an IPv4 infrastructure.

E. It securely routes and tunnels traffic between separate sites over the Internet.

Refer to the exhibit.

A regional service provider provides connectivity for several midsize businesses that run mission-critical applications between multiple offices connected via PE 1 and PE2 Links throughout the service provider network are connected using shared resources and an SRTE tunnel is in use to route traffic over different paths depending on congestion policies The networking team must implement SR updates to reduce downtime in the event of a link failure. Which action must the team take to meet the requirements?

A. Implement SRLG protection to identify a post-convergence backup path

B. Implement BGP timers to support immediate reconvergence when the BGP neighbor relationship status changes.

C. Implement targeted LDP neighbors to prevent unwanted LDP relationships from forming

D. Implement VRFs to segment the network and avoid large-scale network outages when a link fails

Refer to the exhibit.

Which effect of this configuration is true?

A. It sets the keepalive timer to 30 seconds and the hold timer to 240 seconds.

B. It sets the keepalive timer to 30 milliseconds and the hold timer to 240 milliseconds

C. It sets the hold timer to 30 milliseconds and the keepalive timer to 240 milliseconds

D. It sets the hold timer to 30 seconds and the keepalive timer to 240 seconds

A network engineer recently deployed a wireless network for users at a new office to join video conferences wirelessly The existing network consists of routers that are configured for EIGRP and BGP. which are located at several data centers in different physical locations The engineer configured PIM-SSM within a single domain from a single source However, during the testing phase, the video conference failed to work for any of the users. The IPs are reachable and firewalls in the network are configured correctly to allow the traffic. Which action resolves the issue?

A. Configure PIM dense mode to replace P1M-SSM.

B. Configure PIM dense mode with multidomain multicast

C. Configure the devices to send join messages toward a multicast SPT

D. Configure PIM sparse mode to replace PIM-SSM.
