NEW QUESTION 199
An engineer is designing a PIM Anycast RP solution between two data centers. The design must ensure that RP1 in DC1 and RP2 in DC2 inform each other about specific sources that have joined locally. Which solution must the engineer choose?

Provision the RPs on the same IP subnet and extend the subnet at Layer 2 between data centers

Enable MSDP between RPs using separate unique loopback interfaces

Enable MSDP between RPs using the configured Anycast RP address

No action is required because PIM registers from the source will, by default, reach each RP

In Anycast RP, two or more RPs are configured with the same IP address on loopback interfaces. The Anycast RP loopback address should be configured with a 32-bit mask, making it a host address. All the downstream routers should be configured to “know” that the Anycast RP loopback address is the IP address of their local RP. IP routing automatically will select the topologically closest RP for each source and receiver.
MSDP used for Anycast RP is an intradomain feature that provides redundancy and load-sharing capabilities.
Enterprise customers typically use Anycast RP for configuring a Protocol Independent Multicast sparse mode (PIM-SM) network to meet fault tolerance requirements within a single multicast domain.

” You need to have a loopback on each prospective RP router, which is different than the loopback that is being used as the RP address.”

NEW QUESTION 200
Refer to the exhibit.

An engineer is designing a BGP solution for a client that peers with ISP1 for full Internet connectivity and with ISP2 for direct exchange of routes for several third parties. Which action, when implemented on the edge routers, enables the client network to reach the Internet through ISP1?

Run an eBGP session within different VRFs for each ISP.

Advertise a default route for downstream routers within the client network.

Apply the AS-path prepend feature for ISP2.

Apply route filtering such that the client advertises only routes originated from its own AS.

NEW QUESTION 201
An engineer must design a QoS solution for a customer that is connected to an ISP over a 1Gbps link with a 100Mbps CIR. The ISP aggressively drops all traffic received over which is causing numerous TCP retransmissions. The customer is not using any RTP applications but wants to maximize bandwidth usage up to the CIR. Which QoS solution engineer choose?

Policing

Traffic shaping

Policer with markdown

Queuing

NEW QUESTION 202
Drag and drop the descriptions from the left onto the Cisco SD-WAN component they describe on the right.

Explanation:
Answer Area
is responsible for traffic forwarding, security, encryption, QoS,and routing protocols distributes routes and policy information via OMP enables centralized provisioning and simplifies network changes enables the communication of devices that sit behind NAT

NEW QUESTION 203
What following parameters for the EIGRP authentication need to match in order for EIGRP neighbors to establish a neighbor relationship?

Autonomous System number.

K-Values

If authentication is used both: the key number, the password, and the date/time.

The neighbors must be on common subnet (all IGPs follow this rule).

NEW QUESTION 204
Refer to the exhibit.

A network engineer must improve the current IS-IS environment. The Catalyst switch is equipped with dual supervisors. Each time a stateful switchover occurs, the network experiences unnecessary route recomputation. Which solution addresses this issue if the upstream router does not understand graceful restart messaging?

Enable IS-IS remote LFA FRR on both devices.

Enable NSR on the switch.

Enable NSF on the switch.

Configure ISIS aggressive timers on both devices.

NEW QUESTION 205
Drag and drop the characteristics from the left onto the configuration protocols they describe on the right.

NEW QUESTION 206
A branch office has a primary L3VPN MPLS connection back to the main office and an IPSEC VPN tunnel that serves as backup. Which design ensures that data is sent over the backup connection only if the primary MPLS circuit is down?

Use EIGRP to establish a neighbor relationship with the main office via L3VPN MPLS and the IPSEC VPN tunnel.

Use BGP with the multipath feature enabled to force traffic via the primary path when available.

Use static routes tied to an IP SLA to prefer the primary path while a floating static route points to the backup connection.

Use OSPF with a passive-interface command on the backup connection.

NEW QUESTION 207

Refer to the exhibit. A network architect is preparing a network design based on the EIGRR Routers are connected using a cat6a cable type and the inter-router connection speed is limited to 10 Mbps due to distance. During the pilot phase, a DUAL-3-SIA error message is visible. Which action must the engineer take to create a stable design?

Enable poison reverse on R4.

Configure STUB area on R4.

Create a summary route on R2.

Disable split horizon on R1.

NEW QUESTION 208
Which protocol is deployed through LAN automation to build node-to-node underlay adjacencies in SDA?

IS-IS

OLISP

OSPF

VXLAN

NEW QUESTION 209

Refer to the exhibit. Customers report low video quality and delays when having point-to-point telepresence video calls between the two locations. An architect must optimize a design so that traffic follows the same path for egress and ingress traffic flows. Which technique optimizes the design?

Configure route leaking on the router in area 2.

Configure route leaking on the router in area 1.

Configure the high metric on the router in area 4.

Configure route filter on the router in area 4.

NEW QUESTION 210
What is an advantage of using model-driven telemetry in the network?

It uses interrupt-driven polling to pull data at regular intervals.

It uses MIB models to structure the data that are well known in the industry.

It uses JSON encoding and is compatible with a wide variety of tools on the market.

Telemetry obtains data by parsing the CLI output from show commands.

NEW QUESTION 211
Which two tasks must you perform to configure DHCP snooping on a device? (Choose two.)

Enable DHCP packet validation on the device

Enable DHCP option 82

Enable DHCP snooping on the VLAN

Enable DHCP snooping globally

Enable VRF support for the DHCP relay agent

Explanation/Reference: https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/4_1/nx-os/security/configuration/ guide/sec_nx-os-cfg/sec_dhcpsnoop.html

NEW QUESTION 212
A client is moving to Model-Driven Telemetry and requires periodic updates. What must the network architect consider with this design?

Updates that contain changes within the data are sent only when changes occur.

Empty data subscriptions do not generate empty update notifications.

Periodic updates include a full copy of the data that is subscribed to.

The primary push update is sent immediately and cannot be delayed.

Periodic updates contain a full copy of the subscribed data element or table for all supported transport protocols.
