Exam JN0-1301 topic 1 question 14 discussion

I think qfx5110 is correct, you can see it here in description, that qfx5110-48s supports 1gbps transcievers: https://www.juniper.net/documentation/en_US/release-independent/junos/topics/reference/specifications/port-panel-qfx5110-48S.html

Correct but how do you accommodate 1GB access ports on the QFX5110? I don't see any models that can accommodate 1GB access "• QFX5110-48S—A 10GbE/100GbE data center access switch, the QFX5110-48S offers 48 small form-factor pluggable plus (SFP+) transceiver ports and four QSFP28ports that can be configured as 4x40GbE or 4x100GbE ports" And you can use EX4300 in a VCF deployment. I think the question is either incorrect or we should be allowed to choose (2) answers

EX4300-48MP /the one with 10 Gb ports) does not fit VFC: https://www.juniper.net/documentation/en_US/junos/topics/concept/vcf-overview.html QFX5110 has 1 Gb ports: check out QFX5110-48S model

I don't think the QFX5110 will accomodate 1GB access ports (https://www.juniper.net/assets/us/en/local/pdf/datasheets/1000605-en.pdf) I think the only possible correct answer would be to use QFX5110 AND EX4300. The EX4300 will handle the 1 GB Access Ports and is a an acceptable model in VCF (VCF Docs - https://www.juniper.net/documentation/en_US/junos/topics/concept/vcf-components.html)
