I think it depends on two things - what you are interested in and how much time you have. By getting your CCNA (congratulations!) you have a good foundation as a network administrator. You can add to that by studying in an area that you findd interesting - for example you might be interested in security so you could do a general security course or something specific like a manufacturer certification n a popular firewall. What you do will also have to fit in with how long your break is. You've done well and worked hard so give yourself a little time to relax too
