Which of the following statements is true regarding the following /etc/resolv.conf file? search example.com nameserver 208.77.188.166 nameserver 208.77.188.167

The provided `/etc/resolv.conf` file snippet `search example.com` and `nameserver 208.77.188.166 nameserver 208.77.188.167` uses correct syntax for configuring DNS resolution.

DNS queries to localhost are typically handled locally or fail if no local resolver is configured, and the `nameserver` entries are for querying external DNS servers, not for fallback from localhost failures.

`example.com` is not appended to *all* host lookups; it's specifically applied to unqualified hostnames (those without dots) or in some cases, partially qualified names where the initial lookup fails.

The `search` directive in `/etc/resolv.conf` specifies a domain suffix list. When the resolver attempts to resolve a hostname that is a single label (i.e., contains no dots), it appends each domain in the search list, in order, until a match is found or the list is exhausted.

The `nameserver` entries in `/etc/resolv.conf` are queried sequentially in the order they appear, with subsequent servers acting as fallbacks; there is no mechanism for querying based on shortest ping time.
