I have a virtual host site configured on two webservers with ELB as front facing. I have domain.bundle.crt and domain.key on my webservers under /etc/httpd/ssl. I have verified my site at ssllabs.com and got Grade B, so I went through the Criteria Categories through which the ssllabs gives the grade and got below values for my site
Protocol support: TLS 1.2 - 100% Key exchange: 2048 key private key length - 90% Cipher Strength: TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256.128bit keys - 80%

I have got the following results. What could I do to fix this?
