Which set of facts must the network architect consider when deciding whether to implement SaltStack or Chef?
正確答案: C
Refer to the exhibit. The network engineer who manages ASN 65001 is troubleshooting suboptimal routing to the 198.18.15.0/24 prefix. According to the network requirements:
- Routing to IP destinations in the 198.18.15.0/25 block must be
preferred via the EDGE-1 PE.
- Routing to IP destinations in the 198.18.15.128/25 block must be
preferred via the EDGE-2 PE.
- More specific prefixes of the 198.18.15.0/24 block must not be
advertised beyond the boundaries of ASN 64611.
- Routing to 198.18.15.0/24 must be redundant in case one of the
uplinks on INT-R1 fails.
Which configuration must the network engineer implement on INT-R1 to correct the suboptimal routing and fix the issue?
- Routing to IP destinations in the 198.18.15.0/25 block must be
preferred via the EDGE-1 PE.
- Routing to IP destinations in the 198.18.15.128/25 block must be
preferred via the EDGE-2 PE.
- More specific prefixes of the 198.18.15.0/24 block must not be
advertised beyond the boundaries of ASN 64611.
- Routing to 198.18.15.0/24 must be redundant in case one of the
uplinks on INT-R1 fails.
Which configuration must the network engineer implement on INT-R1 to correct the suboptimal routing and fix the issue?
正確答案: C
Refer to the exhibit. A global company plans to implement BGP at its newest location to provide connectivity to other offices. The global infrastructure of the company is a multivendor environment. An engineer must review the BGP core configurations at headquarters to determine if they can be repurposed at the new location. The engineer copied this JSON script for review.
What is the effect of the script?

正確答案: C
After a possible security breach, the network administrator of an ISP must verify the times that several different users logged into the network.
Which command must the administrator enter to display the login time of each user that activated a session?
Which command must the administrator enter to display the login time of each user that activated a session?
正確答案: B

Refer to the exhibit. A network engineer notices PE-21 convergence degradation due to the growing LSDB size of Level 2 areas in the network. The engineer decides to migrate router PE-21 from an inter-area design to an intra-area implementation. Inter-area routing must be accomplished via an ATT-bit set by the Level 1/Level 2 router. Which configuration must the engineer implement on PE-21 to complete the migration?
正確答案: B
Refer to the exhibit. ISP A provides MPLS L3VPN service to customer A with BGP as the external routing protocol. Customer A has just opened a new branch office in London and requested the service provider to implement lossless service between its two offices. The LDP is enabled over the MPLS backbone and label exchange is working normally. Which action must the ISP engineering team take to enable the service?
正確答案: B
Refer to the exhibit. Which configuration prevents the OSPF neighbor from establishing?

Topology
Tasks
Configure and verify the OSPF neighbor adjacency between R1 and R2 in OSPF area 0 according to the topology to achieve these goals:
1. Establish R1 and R2 OSPF adjacency. All interfaces must be advertised in OSPF by using the OSPF interface command method. Use Loopback0 as the OSPF ID.
2. There must be no DR/BDR elections in OSPF Area 0 when establishing the neighbor relationship between R1 and R2. OSPF must not generate the host entries /32 for the adjacent interfaces.
3. Enable OSPF MD5 Authentication between both routers at the interface level with password C1sc0!.
