    A) Yes.

    31) What is the command to start and stop the httpserver?

    A) ./apachectl -k stop/start

    32)What is a keystore?

    A) A keystore is a database that contains private keys with their associated

    certificates. The keystore will be used for encrypting/signing some thing with

    your private key

    33) What is root certificate?

    A) ----> Root certificate is either an unsigned public key certificate or a self-

    signed certificate that identifies the Root Certificate Authority (CA).

    -----> Digital certificates are verified using a chain of trust. The trust anchor

    for the digital certificate is the Root Certificate Authority (CA).

    -----> A root certificate is the top-most certificate of the tree, the private key

    of which is used to "sign" other certificates. All certificates immediately below

    the root certificate inherit the trustworthiness of the root certificate.

    ---->Intermediate certificate is a subordinate certificate issued by the trusted

    root specifically to issue end-entity server certificates. The result is a

    certificate chain that begins at the trusted root CA, through the intermediate

    and ending with the SSL certificate issued to you. Such certificates are called

    chained root certificates

    ----> Creating certificates directly from the CA root certificate increases the

    risk of root certificate compromise, and if the CA root certificate is

    compromised, the entire trust infrastructure built by the SSL provider will

    fail. The usage of intermediate certificates for issuing SSL certificates to end

    entities, therefore, provides an added level of security.

    34) What is the Default Server in WAS for Application Server profile ?

    A) Server1
