NEW QUESTION # 186
Refer to the exhibit.
An engineer implemented OSPF neighbor relationship on an IOS device. Which configuration must be applied to get the OR/BOR election removed from interfaces running OSPF?
- A. ip ospf network broadcast on interfaces running OSPF
- B. ip ospf network multipoint-point on interfaces running OSPF
- C. ip ospf network non-broadcast on n:erfaces running OSPF
- D. ip ospf network point-to-point on interfaces running OSPF
Answer: C
Explanation:
In OSPF, the election of the designated router (DR) and backup designated router (BDR) is based on the OSPF network type. The network types include:
Broadcast: This is the default network type for Ethernet interfaces. In a broadcast network, OSPF elects a DR and BDR. All other routers become DROTHERs. To prevent the election of a DR/BDR, you can configure the interface as non-broadcast (NBMA) using the ip ospf network non-broadcast command.
Point-to-Point: This network type is used for point-to-point links (e.g., serial links). There is no DR/BDR election in point-to-point networks.
Point-to-Multipoint: This network type is used for point-to-multipoint links (e.g., Frame Relay). There is no DR/BDR election in point-to-multipoint networks.
Point-to-Multipoint Non-Broadcast: Similar to point-to-multipoint, but explicitly configured as non-broadcast. There is no DR/BDR election in point-to-multipoint non-broadcast networks.
Loopback: Loopback interfaces are always treated as point-to-point.
Virtual-Link: Used for OSPF virtual links.
Sham-Link: Used for OSPF sham links.
Demand Circuit: Used for demand circuits (e.g., ISDN).
Non-Broadcast: Explicitly configured as non-broadcast. There is no DR/BDR election in non-broadcast networks.

NEW QUESTION # 187
According to RFC5305 on IS-IS extensions for traffic engineering, what is the 4-octet sub-TLV type 10 of extended IS-IS reachability TLV type 22?
- A. IPv4 neighbor address
- B. maximum reservable link bandwidth
- C. TE default metric
- D. administrative group (color)
Answer: B
Explanation:
RFC 5305 extends the IS-IS protocol for traffic engineering by specifying new information that an Intermediate System (router) can place in Link State Protocol Data Units (LSPs). Sub-TLV type 10 of the extended IS-IS reachability TLV type 22 is used to specify the maximum reservable link bandwidth. This is an important parameter for traffic engineering as it defines the amount of bandwidth that can be reserved by traffic engineering algorithms for use in constrained-path computations for MPLS traffic engineering Label Switched Paths (LSPs). Reference: RFC 53051.
NEW QUESTION # 188

To meet service requirements, the service provider must extend the layer 2 domain between the company's two locations. Which configuration must the engineer apply to implement an attachment circuit between the two sites using a VLAN tag of 12?
- A. Option C

- C. Option D
- D. Option B
Answer: B
NEW QUESTION # 189
How can shared services in an MPLS Layer 3 VPN provide Internet access to the customers of a central service provider?
- A. Static routes on CE routers allow route leakage from a PE global routing table
- B. Route distinguishes are used to identify the routes that CEs can use to reach the Internet
- C. The CE router can establish a BGP peering to a PE router and use the PE device to reach the Internet
- D. The customer VRF uses route targets to import and export routes to and from a shared services VRF

NEW QUESTION # 190
Refer to the exhibit:
When implementing an LDP protocol, an engineer experienced an issue between two directly connected routers and noticed that no LDP neighbor exists for 1.1.1.1.
Which factor should be the reason for this situation?
- A. LDP needs to be enabled on the R2 loopback interface
- B. LDP needs to be enabled on the R2 physical interface
- C. R2 does not see any hellos from R1
- D. R2 sees the wrong type of hellos from R1
Answer: C
Explanation:
The issue of no LDP neighbor existing for 1.1.1.1 between two directly connected routers could be due to R2 not receiving any hellos from R1. In the context of LDP (Label Distribution Protocol), hellos are used for the discovery of LDP peers. They are sent periodically on each interface that LDP is enabled on to discover and maintain LDP sessions with neighbors. If R2 is not seeing any hellos from R1, it means there's a failure in the initial step of establishing an LDP session, hence no neighbor relationship is formed.
Implementing and Operating Cisco Service Provider Network Core Technologies source documents or study guide can provide more insights into the workings and troubleshooting steps for LDP protocol.
NEW QUESTION # 191
Refer to the exhibit.
A network engineer is implementing a standard customer route-policy on ASBR1 with these requirements:
* It must accept only customer-assigned prefixes
* It must preserve customer advertised BGP communities
* It must set the local-preference to 110 for all prefixes
* It must attach the ORIGINATION-PE and LOCAL-CITY communities to all accepted prefixes.
Which route policy must the engineer implement on ASBR1 to satisfy the requirements?
- A. Option D
- B. Option B
- C. Option A
- D. Option C
Answer: D
Explanation:
The correct route policy to satisfy the requirements is Option C. This option likely contains the necessary commands to:
Accept only customer-assigned prefixes, which can be specified using an access list or prefix list.
Preserve customer advertised BGP communities, which is typically done with the set community command along with the additive keyword to ensure existing communities are not overwritten.
Set the local-preference to 110 for all prefixes, which is achieved with the set local-preference 110 command.
Attach the ORIGINATION-PE and LOCAL-CITY communities to all accepted prefixes, which would also use the set community command with both community values specified and the additive keyword.
NEW QUESTION # 192
Refer to the exihibit.
Refer to the exhibit. Routers R1 through R5 are being deployed within the core of a service provider running BGP The core supports distribution of VPNv4 routes using MPLS. R3 currently has multiple paths to reach R4. A network engineer must implement BGP attributes so that R3 can reach R4 via R1. Which action must the engineer take to meet the requirement?
- A. Configure R3 so the route to R4 through R1 will have a higher weight than the route from R2 or R5.
- B. Configure R5 to send the route from R4 to R1 using a longer AS path than the AS path that it receives from R1 or R2.
- C. Configure R3 so the route to R4 through R1 will have a lower local preference than the route from R2 or R5
- D. Configure R2 to send the route from R4 to R1 using a higher metric than what is advertised to R3.
Answer: A
Explanation:
To direct traffic from R3 to R4 via R1, the weight attribute on R3 can be set higher for the route through R1 compared to other routes. Weight is a Cisco-specific BGP attribute that determines the preferred path when multiple routes to the same destination exist. It is local to the router on which it is configured and not advertised to other BGP peers.

However, local-preference configuration is not permitted on R1. Which task must the engineer perform on R1 to complete the implementation?
- A. Enable MED comparison between routes from neighbors in different AS.
- B. Set the device to ignore the conditional MED if the route originated in a different autonomous system.
- C. Configure the device to choose the best MED from the same AS.
- D. Implement deterministic MED to choose the best route from the different AS.

Drag and drop the functions from the left onto the correct Path Computation Element Protocol roles on the right
Answer:
Explanation:
Explanation
Path Computation Element (Calculates paths through the network, keeps TE topology database information, sends path status updates) Path computation Client (sends path calculation request, sends path creation request) Path Computation Element (PCE) Represents a software module (which can be a component or application) that enables the router to compute paths applying a set of constraints between any pair of nodes within the router's TE topology database. PCEs are discovered through IGP.
Path Computation Client (PCC)
Represents a software module running on a router that is capable of sending and receiving path computation requests and responses to and from PCEs. The PCC is typically an LSR (Label Switching Router).
