NEW QUESTION # 219
Which feature describes the weight parameter for BGP path selection?
- A. Its value is local to the router
- B. Its value is global to the router.
- C. Its value is set either locally or globally.
- D. Its default value is 0.
Answer: A
Explanation:
The weight parameter in BGP (Border Gateway Protocol) is a Cisco-specific attribute that is local to the router on which it is configured. It is used to prefer one path over another when multiple paths to the same destination are available. The weight is not advertised to other routers, making it a local parameter.
NEW QUESTION # 220
Refer to the exhibit:
What is significant about the number 2 in the configuration?
- A. It dictates the number of sessions that can be open with the SNMP manager
- B. It indicates two SNMP managers can read and write with the agent using community string cisco test
- C. It represents the version of SNMP running
- D. It is the numeric name of the ACL that contains the list of SNMP managers with access to the agent
Answer: D
NEW QUESTION # 221
Refer to the exhibit.
What does this REST API script configure?
- A. application profile
- B. VRF
- C. interface with IP address 192.168.0.1
- D. public community string for SNMP
Answer: C
NEW QUESTION # 222
Refer to the exhibit. A network engineer with an employee ID: 5086:72:817 is configuring a connection to manage CE1 from the OAM server on VLAN 100. PE1 must push S-VLAN tag 10 toward PE2 while forwarding traffic from CE1 to the OAM server. PE1 must push S-VLAN tag 20 toward PE2 while forwarding traffic from CE2 to the data traffic gateway. Which configuration must the engineer implement on PE2?
- A. Interface Ge0/1
encapsulation dot1q 100
rewrite ingress tag translate 1-to-1 dot1q 20 - B. Interface Ge0/1
encapsulation dot1q 10
rewrite ingress tag push dot1q 10 symmetric
Interface Ge0/0
encapsulation dot1q 20
rewrite ingress tag push dot1q 20 symmetric - C. Interface Ge0/0
encapsulation dot1q 100
rewrite ingress tag push dot1q 10 symmetric
Interface Ge0/1
encapsulation dot1q 200
rewrite ingress tag push dot1q 20 symmetric - D. Interface Ge0/1
encapsulation dot1q 100
rewrite ingress tag pop 10
rewrite ingress tag push 20
Answer: A
Explanation:
On PE2 you must map the incoming S-VLAN tags directly into the CE-VLAN. The one-to-one translate command does exactly that - any packet arriving with S-VLAN-20 is rewritten into C-VLAN-100 on the CE-facing subinterface.
PE2(config)# interface GigabitEthernet0/1
PE2(config-if)# encapsulation dot1q 100
PE2(config-if)# rewrite ingress tag translate 1-to-1 dot1q 20
This ensures that traffic PE1 has S-tagged with 20 (from CE2) is presented to the CE3/OAM server on VLAN-100.
NEW QUESTION # 223

NEW QUESTION # 240
In an EVPN operation, how does the PE determine and advertise Ethernet segment reachability?
- A. The PE discovers remote ESIs and determines their redundancy mode.
- B. The PE discovers other PEs in the same Ethernet segment and elects a DF.
- C. The PE discovers and shared routing information for the B-MAC addresses associated with local Ethernet segments.
- D. The PE discovers the remote PEs in the EVI and builds a flood list linked with the EVI.
Answer: A
Explanation:
In an EVPN operation, the PE (Provider Edge) router determines and advertises Ethernet segment reachability by discovering remote ESIs (Ethernet Segment Identifiers) and determining their redundancy mode (all-active or single-active). This is crucial in multihoming scenarios where the PE needs to auto-discover remote PEs and the corresponding redundancy mode. In case of segment failures, PEs withdraw the routes used at this stage to trigger fast convergence by signaling a MAC mass withdrawal on remote PEs3.
