NEW QUESTION # 170
Refer to the exhibit. An architect reviews the low-level design of a company's enterprise network and advises optimizing the STP convergence time. Which functionality must be to Gi1/0/1-10 to follow the architect's recommendation?
Answer: B
NEW QUESTION # 171
An engineer is upgrading a company's main site to include a connection to a second ISP. The company will receive full Internet routing tables from both ISPs via BGP. The engineer must ensure that the company does not become a transit autonomous system. Which solution should be included in this design?
Answer: D
Explanation:
There are 4 methods how you can prevent becoming a transit AS:
- Filter-list with AS PATH access-list.
- No-Export Community.
- Prefix-list Filtering
- Distribute-list Filtering

NEW QUESTION # 172
Drag and drop the characteristics from the left onto the correct telemetry mode on the right.
Answer:
Explanation:
In a dial-in mode, the destination initiates a session to the router and subscribes to data to be streamed. Dialin mode is supported over gRPC in only 64-bit platforms In a dial-out mode, the router initiates a session to the destinations based on the subscription. All 64-bit IOS XR platforms (except for NCS 6000 series routers) support gRPC and TCP protocols. All 32-bit IOS XR platforms support only TCP.

NEW QUESTION # 173
Refer to the exhibit.
An engineer is designing a routing solution for a customer. The design must ensure that a failure of network
10.1.0.0/24, 10.1.2.0/24, 10.2.1.0/24, or 10.2.3.0/24 does not impact the core. It also requires fast convergence time during any link failover in the core or access networks. Which solution must the engineer select?
Answer: C
Explanation:
Summarization on routers A and C is the correct design because the requirement is to keep failures of the listed access networks from impacting the core while still supporting fast convergence in both access and core. Route summarization creates an aggregation boundary: more-specific access routes can flap behind the summary without causing the core to learn and withdraw every individual prefix. Cisco hierarchical routing design uses summarization at distribution or aggregation boundaries to reduce routing-table size, contain convergence events, and protect the core from access-layer instability. Adding another aggregation layer may be appropriate in some large designs, but it is not necessary when the question asks for the mechanism that stops specific prefix failures from impacting the core. Graceful restart protects forwarding during control- plane restart events, not ordinary access-prefix failures. FRR provides fast reroute for link or node failures but does not hide individual connected-network changes from the core. Summarizing at routers A and C directly addresses the stated networks and reduces the query, LSA, or update impact depending on the routing protocol used. Reference topics: route summarization, hierarchical routing, convergence containment, core protection, prefix aggregation.
NEW QUESTION # 174
An engineer must design a management network that enables SSH, NTP, FTP, and SNMP over the production network. The design requires the management of routers and switches that exist across different networks. Which feature must the design include?
Answer: B
Explanation:
A dedicated management VRF is the correct feature when management protocols must traverse the production network but remain logically separated. The question describes in-band management because SSH, NTP, FTP, and SNMP are carried over the production network rather than over a separate physical console or out- of-band network. The design still requires routers and switches across different networks to be managed securely. A management VRF gives the management plane its own routing table, allowing the engineer to restrict management reachability, apply separate routing, and keep management traffic from leaking into user or service forwarding paths. Management Plane Protection can restrict which interfaces accept management- plane traffic, but it does not by itself provide separate routing across different networks. A terminal server or dedicated console connection is an out-of-band operational tool, not the production-network management design requested here. A dedicated management VRF per device is therefore the correct feature. Reference topics: in-band management, management VRF, SNMP and SSH reachability, management-plane segmentation, enterprise operations design.
