Exam JN0-649 topic 1 question 7 discussion

I think it's ABE When enabling MSTP, you define one or more MSTP regions. An MSTP region defines a logical domain where multiple spanning-tree instances (MSTIs) can be administered independently of MSTIs in other regions, setting the boundary for bridge protocol data units (BPDUs) sent by one MSTI. An MSTP region is a group of switches that is defined by three parameters: Region name—User-defined alphanumeric name for the region. Revision level—User-defined value that identifies the region. Mapping table—Numerical digest of VLAN-to-instance mappings. https://www.juniper.net/documentation/us/en/software/junos/stp-l2/topics/topic-map/spanning-tree-configuring-mstp.html

According to AJES training (Revision 21A), page 104

a,b,c sure

The correct answer is ABC by using the elimination method see : user https://supportportal.juniper.net/s/article/EX-series-Switch-and-MSTP-Multiple-Spanning-Tree-Protocol?language=en_US

As per AJEX training.

A B and C - Juniper doesn't have an option for region name. VLAN TO instance mapping REvision and COnfiguration name

tricky one, since configuration-name and region name refer to the same thing, since they mention config parameter, it choose ABC

Region name and configuration name are basically the same. But the question is looking for specifically for config parameter. In config, the word used is configuration-name.

ABE is the correct answer

ABE is the correct answer

ABC valid answers

Wrong. Correct answer ABE An MSTP region is a group of switches that is defined by three parameters: Region name—User-defined alphanumeric name for the region. Revision level—User-defined value that identifies the region. Mapping table—Numerical digest of VLAN-to-instance mappings.
